Latest Developments and Application of Nonwoven
Starting with a keynote on the Present & Future of the Chinese Filtration and Separation
Business by Wang Yanxi, Chairman of the Chinese Filtration Society, the conference will
review the latest developments in nonwoven filter media for the region and across the
globe. Experts from market leaders will also feature a review of trends and innovations in
air, liquid and automotive filtration. This comprehensive programme is complemented by
a session on filter testing and standards.
Unique promotional opportunity
―Opportunities for companies to present and discuss individual products and services
with potential customers are included,‖ said Mr Wiertz. ―The tabletop exhibition is an
important feature of all FILTREX events, and this will make FILTREX Asia 2015 not only
the highest level conference this year in Asia for nonwoven filter media, but also a unique
promotional opportunity for all companies with particular interest in the Chinese and
Asia-Pacific filtration market.‖
FIGHTING A DEVASTATING EPIDEMIC
Protective clothing and accessories such as facemasks and shoe covers based on nonwovens are essential components of the comprehensive personal protective equipment (PPE) that is recommended for dealing with the current Ebola virus in West Africa. The US Centers for Disease Control (CDC) is advising that anyone entering a patient room should wear at least gloves, a fluid resistant or impermeable gown, goggles or a face shield and a facemask. Additional PPE may be required in certain situations, including but not limited to, double gloving, disposable shoe covers and leg coverings. Such protective clothing is already widely employed in many countries, and single-use nonwoven-based gowns and drapes are well-proven in hospitals and other medical environments as extremely effective tools in fighting healthcare associated infections (HAIs). In the EU, for example, patient safety is now top of the agenda in every hospital, Page No. 11
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
with one in eight patients said to be impacted by HAIs. According to the European Centre for Disease Prevention and Control (ECDC), the direct cost of HAIs is now €7 billion each year, with and €1.2 billion is attributable to surgical site infections alone. In orthopedic surgery, such an infection can prolong a hospital stay by two weeks, increasing health care costs by more than 300%. The key advantages of single-use nonwoven-based protective garments include: o Simple logistics – they are bought, used and then disposed of. o For every single surgery, the products are new, clean and unused every time, providing confidence and security. o They give hospitals the flexibility to choose the preferred systems for every procedure. Drapes and gowns can be chosen from a range of models to ensure that they provide the right level of protection at the right price. o They are budget-friendly, with no hidden costs such as laundering, repairing, re- sterilization or re-packaging. The costs of single-use drapes and gowns are known for every procedure. During 2013, EDANA –the international association serving the nonwovens and related industries which sponsors the tri-annual INDEX™ shows held in Geneva – welcomed a new report prepared by the ECDC, making a number of recommendations for dealing with HAIs. ―Experience has shown that in surgery, single-use surgical barrier materials – gloves, gowns, drapes and masks – are a key factor in preventing the transfer of micro-organisms,‖ says EDANA General Manager Pierre Wiertz. ―Although in Europe the market penetration of single-use gowns and drapes has reached around 60-65% – taking into account geographical differences – this is still significantly lower than in the USA. More has to be done to help increasing that penetration and thus contribute towards better infection control to reduce HAIs.‖ The significance of disinfecting wipes and other nonwoven-based cleaning materials in fighting HAI‘s should also not be overlooked. Nonwoven protective clothing was also widely deployed to deal with previous epidemic scares, including the 2003 SARS outbreak, the wave of Bird Flu that swept through south-east Asia in 2005 and during the Swine Flu panic of 2009, when the demand for face masks, in particular, exploded on a global scale. The major manufacturers of nonwoven protective clothing for healthcare workers are currently reported to be working around the clock to meet fresh demand in response to the Ebola threat and there is optimism that the epidemic can eventually be brought under control using such recognised public health containment measures. It‘s acknowledged, however, that this may not be enough, and researchers at laboratories in Britain, Canada, the USA and Mali Page No. 12
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
are currently racing to develop vaccines that can be rushed to West Africa before the end
of 2014. By that time, however, it is estimated that the number of Ebola cases will have
reached as many as 1.4 million.
Ebola first appeared in 1976 in two simultaneous outbreaks, in Sudan and the Democratic
Republic of Congo. It is introduced into the human population through close contact with
the blood, secretions, organs or other bodily fluids of infected animals. In Africa, infection
has been documented through the handling of infected chimpanzees, gorillas, fruit bats,
monkeys, forest antelope and porcupines found ill or dead or in the rainforest. Ebola then
spreads in the community through human-to-human transmission, with infection
resulting from direct contact (through broken skin or mucous membranes) with the
blood, secretions, organs or other bodily fluids of infected people, and indirect contact
with environments contaminated with such fluids. Human-to-human transmission of the
Ebola virus is primarily associated with direct or indirect contact with blood and body
fluids and transmission to health care workers occurs only when appropriate infection
control measures have not been observed. However, it‘s not always possible to identify
patients with the virus early, because initial symptoms can be non-specific. For this
reason, health care workers are being urged to apply standard precautions consistently
with all patients – regardless of their diagnosis – at all times. These include basic hand
hygiene, respiratory hygiene, safe injection practices and the use of personal protective
equipment.
ADJUSTING THE VERTICAL FOR BULK BENEFITS
Although there are many applications for nonwovens in which the ability to pack multiple performance properties into an extremely thin format is appreciated, sometimes a little bulk is required. This is particularly the case when materials are being employed for insulation, for cushioning, or for filling, in applications such as mattresses and bedding, furniture, automotive upholstery and construction materials. Traditionally, the nonwovens produced for such functions have been made from self-crimping staple fibres and processed on drylaid, mechanical technologies. Crosslapping machines serve to Page No. 13
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
successively layer loosely-bound nonwoven webs into the required thickness prior to them being consolidated, usually by needlepunch machines or thermobonding calendars.But in addition to thickness, it‘s also advantageous in many cases for thick nonwovens to contain a high percentage of air, making them lighter, more breathable and with greater resilience and recovery from compression. These are some of the key advantages of so-called ‗high loft‘ nonwovens, and specifically of the latest ‗vertically lapped‘ materials, which are characterised by an extremely high uniformity due to the vertical orientation of their fibres. Shedding weight
Car manufacturers, for example, have been constantly looking to alternative energies and
smaller cars for reduced fuel usage, but shedding the weight of components while
achieving the same performance level can be just as critical. As a consequence, vertically-
lapped nonwovens are now being employed by many of the leading car manufacturers in
products such as door insulators, headliner pads and base materials, under-carpet
insulators and bonnet and trunk liners.
They can also be equally effective solutions in other industrial areas such as building and
construction and the furniture markets too, while in filtration, the unique structure of
vertically-orientated webs improves both coarse particle holding on the surface and depth
holding of the finer particles, resulting in filters with a very low pressure drop and
excellent dust holding capacity. The ability to provide increased bulk without adding
weight provides for greater air circulation and a cooler feel than typical bonded
nonwovens. Vertically-lapped products are more foam-like than other filling media,
achieving a reduced weight/cost balance at comparable thicknesses, while delivering
pressure relief, comfort and support properties. In mattress construction, meanwhile,
vertically-lapped high loft materials are used with strong scrims for spring pocket
insulator materials, and as mattress topping materials which are much more foam-like
than conventional crosslapped polyesters. The improved compression and recovery does
not compromise the soft feel of these materials, while the ability to provide improved bulk
without weight provides for much more air circulation and a ‗cooler‘ feel.
Skinning
But adding scrims – usually synthetic mesh materials – to these nonwovens to provide
stability also adds cost, and in a further recent development, a new term has entered the
nonwoven industry vocabulary – ‗skinning‘.― ‗Skinning‘ refers to running a web or fabric
containing thermoplastic fibres under a heated calender roller that just rests gently on its
surface – rather than squeezing it – so that only the fibres in the outer layer are
compressed and fused together,‖ explains Professor Stephen Russell, director of the
Nonwovens Research Group at the University of Leeds. ―You might think of it as glazing
the surface. You can achieve similar effects using other heat sources as long as they only
act on the surface.‖Following investment in the latest technology for vertically lapped
nonwovens production, the UK company John Cotton has this year commissioned a new
Page No. 14
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
thermal bonding line solely dedicated to the skinning process and employed to produce a
range of glazed-surface materials, including its latest Airstream products. Airstream
nonwovens are the subject of a number of new patent applications in respect of their
special ‗convoluted and zoned‘ structures. They can be manufactured from a range of
natural, synthetic, recycled and blended fibres at various web weights and product
densities. In addition, they are odour free, contain no VOC‘s (Volatile Organic
Compounds) and are cradle-to-cradle recyclable. They are also hypo-allergenic and
washable.
Spunbonding
While voluminous high loft or vertically-lapped nonwovens have many advantages,
however, their production has been restricted to self-crimping staple fibres and it has not
been possible to manufacture them using the much faster spunbonding technology which
now accounts for by far the highest percentage of all nonwovens manufactured
worldwide. This may be about to change. Germany‘s Reifenhäuser Reicofil reports success
in the development of a spunbonding process exploiting bicomponent technology for the
production of new high loft nonwovens. This latest process is based on two filaments of
different raw materials being extruded in a side-by-side structure. Self-crimping of the
filaments can be caused by the combination of the different materials or activated by
thermal energy. The resulting nonwoven fabrics are subsequently bonded using hot air or
a special embossing calender. Reicofil says these thick, soft nonwovens are well suited for
applications in which carded nonwovens are currently being employed and that in the
future it expects to be able to offer the technology for producing high loft nonwovens
much more cost-effectively. It also sees possible new applications for such materials in the
major hygiene market, as, for example, topsheets and backsheets in premium diapers. As
will be demonstrated at the 2017 edition of INDEX™ – the industry‘s leading exhibition
which next takes place at Palexpo in Switzerland from 4th-7th April 2017 – the
technologies for producing nonwovens are in a constant state of evolution, and often the
processes for one application can be successfully adopted by another.
BROTHERS IN ARMS FOR FINE FILTRATION
Page No. 15
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
Nonwovens and membranes are considered to be very separate products
which in fact, in many filtration applications, are highly interconnected.
Nonwoven media-based filtration processes are not generally considered
absolute methods of purification, since particles of the size of one micron or
less can pass through them into the filtrate.

Typical pore sizes for microfiltration membranes are in the range of 0.1 microns to 0.45
microns, whereas a meltblown nonwoven media‘s pore opening is at least ten times
larger. Membranes, however, are manufactured by solvent casting or spinning, biaxial
stretching, sol-gel and other sophisticated processes which make them much more
expensive to make than nonwoven filter media. It‘s for this reason that work is ongoing in
attempting to develop nonwoven filter media that are capable of achieving the
performance of membranes. Nanofibres must surely be the key to this, and also promise
to make single material products for microfiltration possible – as opposed to the
laminates which are widely employed at present.
Sugar cube
At the 2014 OUTLOOK™ conference for nonwoven personal care and hygiene products in
Barcelona, Bryan Haynes of Kimberly-Clark spoke of the incredible scale that is
achievable with nanofibres. A small cube of polypropylene, the size of a sugar cube, with
sides of 1.58cm weighing 3.5 grams, he pointed out, can support the production of 15
micron spunbond fibres that would stretch for 14 miles. The same amount of
polypropylene employed to make 3 micron meltblown fibres, meanwhile, would result in
350 miles of fibre. But that same sugar lump employed to make 300 nanometre
nanofibres, would result in enough to stretch 35,000 miles. ―The questions is,‖ Haynes
asked, ―how can we produce these fibres cost effectively on a mass scale?‖
Disruptor
A product which has attracted a great deal of attention across many areas of the filtration industry is Ahlstrom‘s Disruptor. Disruptor‘s filter effect works by both electrical charge and mechanical entrapment. It employs a submicron microglass support fibre to which nanofibres are attached, to result in an average pore size of 2 microns – so a square metre of this material has more than 42,000 square metres of available nanofibre surface. Another product employing nanofibres is DuPont Hybrid Membrane Technology (HMT), which is billed as filling the performance gap between meltblown nonwovens and microporous films. HMT nanofibre sheets contain continuous polymeric filaments with diameters between 200 and 600 nanometres and have been available on a commercial scale for a number of years now. So nonwovens are getting close to the performance of membranes and there will be many examples of attempts to get them closer on show at the next edition of INDEX™, the industry‘s leading exhibition which takes place at Palexpo in Switzerland from 4th-7th April 2017. Page No. 16
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
Integrity
However, most membranes lack the mechanical strength that is often required in harsh
operating conditions and in many applications – most notably for liquid filtration and
separation – need nonwovens to provide it. Membranes supported by nonwovens exhibit
significantly longer lifetimes compared with conventional unsupported membranes and
their complexity depends on this required mechanical strength. In addition, the
nonwoven can also improve overall particle-retention capacity. Companies like
Freudenberg Filtration Technologies supply nonwovens that are specifically engineered
for the membranes employed in micro-filtration, ultra-filtration or reverse osmosis
processes to suit a number of filter configurations – flat, tubular or cartridge. Flat
membranes are employed in many filter systems of different configurations and sizes – in
spiral windings, plate or cassette modules and in punched blanks. Usually, these
membranes are so thin and fragile that they can only be produced by being directly coated
onto the carrier nonwoven‘s surface. In order to produce flawless membranes, such
carrier nonwovens have to exhibit a high degree of uniformity in terms of thickness,
porosity and surface properties. In addition, very good fibre bonding with the membrane
is essential in order to reduce defects. In the continuous production process for tubular
membranes, meanwhile, a narrow strip of the nonwoven carrier is wound to form a tube,
welded using ultrasonics, and coated with the membrane solution. This process and the
application conditions (particularly the maximum operating pressure and temperature)
require nonwovens with high longitudinal and transverse strength, rigidity and good
weldability. Suitability for welding in turn demands an appropriately uniform density and
thickness. Filter cartridges with pleated membranes will deliver their maximum
performance only if the filter‘s entire surface area can actually be used. Nonwovens make
this possible by acting as ‗spacers‘ between the pleats on the face side and as a drainage
layer on the clean side. The nonwoven media‘s performance profile can be very
specifically modified in terms of weight per unit area, thickness or permeability and in
addition, the nonwovens can be easily pleated without damaging the membrane, prior to
converting.
AN ADULT MATTER
Page No. 17
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
Incontinence products for adults are increasingly resembling regular cotton briefs as a result of sophisticated constructions and innovations in nonwovens, elastics and films. Not too long ago, sufferers had very restricted choice – the products available were little more than larger versions of baby diapers, bulky and often with serious fit issues. As a result, they were less effective and users had to dress around them. Today‘s products can be virtually invisible under even the tightest of clothing, providing the three qualities that users most need – comfort, security and discretion. They are available in different sizes, shapes and functional performance levels, required to address different levels of the problem, as well as coming in gender and age-specific variants. One of the key innovations introduced into pant-like products over the past few years include better elastic components. The elastane yarns employed in such products can gather together in hot atmospheres, and the laminate within the product becomes relaxed, giving the pant unwanted bulk. Some manufacturers have solved this problem by adding additional closely-positioned rows of thinner elastane yarns. Others are employing laminates of plastic films and nonwovens to provide flat, cloth-like stretch. The use of apertured films also adds breathability. Both apertured elastic film/ nonwoven laminates and apertured film acquisition and distribution layers (ADLs) have been successfully introduced by several leading adult incontinence product manufacturers, and polyolefin elastomers have been introduced as the primary stretch material in elastic film formulations. Ultra-thin absorbent cores have, without doubt, been another major development, with superabsorbent polymers increasingly replacing bulky fluff pulp and some cores even becoming completely fluff free. Combinations of airlaid nonwovens and superabsorbent polymers have also contributed to reducing the size of the cores. Some of today‘s products are also being engineered to be as ‗cotton-like‘ as possible and are heavily promoted as such. The use of ―cellulosic‖ materials (made of viscose, which is more accurately described as regenerated cellulose) to replace spunlaid polypropylene topsheets is also currently finding favour. Before the advent of polypropylene spunbond, which, for a number of years have been the material of choice for topsheets as a result of evident cost and performance benefits (especially in terms of fluid management), the previous mainstream technologies for this end use had been carded polypropylene thermobonded nonwovens, and before these, carded viscose-or viscose/polyester based webs. Now, however, the textile-like qualities of viscose-based nonwovens – especially the more hydrophobic, spunlaced variants – are increasingly promoted. As visitors to INDEX™ 17 – the next edition of the leading nonwovens show which takes place at Palexpo in Switzerland from April 4th-7th 2017 – will discover, innovations in product designs and material applications for adult incontinence product solutions continue to accelerate market penetration. The potential global market for adult incontinence products is now growing faster than those for either baby diapers or feminine hygiene products, at an average of 8% per year. It is well known that the world population of people over the age of 65 continues to grow. Back in 1950 this segment of the world‘s consumers represented just 5% of potential users, and by 2050 will represent 16%, or 1.5 billion people. For many Page No. 18
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
of them, increasingly-sophisticated adult incontinence products will contribute positively
towards maintaining active lifestyles and even to being able to live independently at
home. It is therefore unsurprising that this year the consumer products giant Procter &
Gamble has decided to re-enter this market, building on the success of its ‗Always‘
femcare brand; the market has become simply too big to ignore.
ON YOUR BIKE
Suppliers of nonwovens and related materials to the automotive industry should pay special attention to what‘s happening right now in China – once known as the Kingdom of Bicycles. The country is the bedrock for all automotive industry growth forecasts, and car production in China has been meteoric – as, for that matter, has been the production of nonwovens. In 2010 China became the largest car and light vehicle producer in the world, outputting some 13.6 million units. Last year, production was up to 22.1 million. There is a strong relationship between the growth of car ownership and GDP and household income, of course, just as there is with the penetration in the country of nonwoven-based absorbent hygiene products. Twenty years ago, back in 1995, China‘s annual GDP per capita was just US$1,500 and it has now rocketed to around $10,000 and is still growing. In 1985, meanwhile, the penetration of femcare products was around 30% and has consequently risen to above 90%. Diapers were virtually unheard of in China in 1995 but are now approaching 50% market penetration. In parallel, Chinese spunmelt nonwovens production has climbed from virtually zero in 1995 to approaching two million tons in 2013. At the same time, China is now taking sustainable issues very seriously, and specifically, is looking to curb pollution. In the Chinese government‘s current five-year plan (2011-2015), it committed to investing US$1.6 trillion on clean energy and manufacturing efficiency investments and at the same time, is also pursuing a goal of ―harmonious urbanisation‖ and the shift to intelligent cities. Most notably, during 2013, Beijing was the first city to impose a cap on new vehicle registrations to keep the overall number of vehicles down to 150 per thousand people. Three other major Chinese cities – Shanghai, Guangzhou and Guiyang – have already followed suit and introduced restrictions, and eight more will shortly follow. Such actions are not likely to be limited to Page No. 19
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
China either. Speaking at EDANA‘s recent Filtrex conference held in Berlin, Germany, Philip G. Gott, of leading US analyst IHS Automotive, suggested that Asian cities will not grow to the motorisation rates of the West. ―Congestion now costs cities billions each year,‖ he said. ―It impedes the efficient movement of goods and manufacturing within them suffers as a result, and employers eventually move out. At the same time, it‘s beneficial to keep people clustered in cities, so mass transportation infrastructure and alternatives to the car are essential for progress. Car ownership peaks as a function of population density and at ten thousand people per square kilometre it starts to go down.‖ And by 2035, this will mean there will be 260 million fewer light vehicles on the roads than there are today, as older cars reach the end of their life and are not replaced. In seeking to reduce CO2 emissions through greater fuel economy, weight is currently preoccupying the car manufacturers and this is an area in which nonwovens – often in combination with other textile materials – can contribute significantly. As a result of higher demand for increased comfort and improved safety, the use of textile materials has increased from 20 kg in a mid-size car in 2000 to 26 kg today. Many current developments include new uses for fabrics, and by 2020, it is predicted that the same sized car will contain 35 kg of textiles. As will be evident at the next INDEX™ nonwovens show, which takes place from April 4th - 7th 2017, new applications for nonwovens for the automotive industry continue to be found. In the longer term, however, this market will perhaps not seem quite as attractive as it does today? LESS IS MORE WITH AEROGEL NONWOVENS
Aerogel-containing nonwovens are increasingly appearing in the extreme performance outdoor gear of major sports brands, including Adidas, The North Face, Rocky and Salomon. In boots and jackets they provide unprecedented insulation properties whilst at the same time being comprised of more than 90% air. And this is only one of the extraordinary things about these ultra-thin nanoporous materials, consisting of an amorphous silica gel which is generally impregnated into a flexible polyester nonwoven Page No. 20
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
substrate. In fact, ultra-silica aerogels – first developed by NASA back in the 1930s and subsequently employed in space suits and rocket components – now hold no less than six world records for the physical properties of all solids, having: o The highest thermal insulation value. o The lowest density. o The highest specific surface area. o The lowest refractive index. o The lowest speed of sound. o The lowest dielectric constant. This means that they can, for instance, be 39 times more insulating than the best
fibreglass insulation and at the same time are 1,000 times less dense than glass.
A wafer thin layer of aerogel is sufficient to protect a hand from blowtorch just inches
away from it, while a block the size of a person weighs less than half a kilo, looks like it
would blow away in a slight breeze and is capable of holding up a small car.
Industrial uses
Not surprisingly, these materials have been exploited in some very extreme industrial
applications, such as providing the insulation for sub-sea oil and gas pipelines. Here,
while the aerogel nonwovens guarantee the lowest thermal conductivity of any insulation,
they also ensure minimum temperature drop along the line and at the same time are
much thinner than other insulation materials, so the outer carrier pipe can be smaller and
less costly. They have proved just as effective in the insulation of local energy supply
infrastructure, including steam, hot water and condensate piping and equipment, in
addition to towers, tanks and both low and high-temperature ducts. In these applications,
their water resistance offers a further level of protection against corrosion. And by their
nature, aerogels are just as efficient at protecting from heat as they are from the cold –
encapsulated in nonwovens they can span a service temperature range from –270°C to
+650°C!
Buildings
In terms of building insulation, there could perhaps be no better reference than The
Pentagon in Washington DC. In a recent building scheme there, fibreglass panels were
first employed in the cavities between the solid masonry and the metal stud frame walls.
These though, were found to still allow ‗thermal bridges‘, which are recognised paths for
heat loss and inefficiency. When a layer of aerogel-containing nonwovens were added, the
insulation was recorded as improving by 23%, with a comparable reduction of both
Page No. 21
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
heating costs and greenhouse gas emissions. At the other end of the scale, a UK company
called My Space Pod has been promoting the conversion of used shipping containers into
self-contained and inexpensive bedroom units. A North London factory full of them
showcases their potential as the individual components of, for example, student halls of
residence, but also social housing developments, with each ‗pod‘ containing a desk, bed,
an en-suite shower room and an array of storage space. Each room is pre-wired with
telephone, TV and Internet, via ducts running through the internal build up so that
alterations or upgrades can be made simply in the future. It is anticipated that the
MySpace Pods will have a working life in excess of 60 years and in addition to maximising
the living space, the closest attention to detail has been paid to material selection and
quality. The highest possible sound and heat insulation is provided by a combination of
Rockwool and aerogel-containing nonwovens, overlaid with reinforced plasterboard to
ensure residents have no sense of actually living in a steel box.
Encapsulation
Until well into the 1990s, the high cost of producing aerogel nonwovens prevented their
widespread application beyond high-cost components for the aeronautic, space and
defence industries. Today, however, they are regularly being specified for insulating and
soundproofing new buildings. But handling these materials remains tricky since they are
dusty and tacky-feeling, and for their incorporation into layers of clothing, a further
processing step has been necessary. A US company called Aerotherm, based in Clinton,
Massachusetts, has now developed a way to encapsulate the aerogel nonwovens
into polyurethane membranes making them easier to handle and more suitable for
incorporation into apparel and footwear. The rapid adoption of these advanced insulating
layers by such major sports brands is largely as a result of the considerable weight
reduction they make possible, while ensuring maximum performance. The successful
launch of new products that are dependent on the versatility of engineered nonwovens
continues to surprise, and is one of the key strengths of INDEX 14, the industry‘s leading
showcase for nonwovens innovations, which is taking place this year at Geneva Palexpo in
Switzerland from April 8-11.
KNOWING HOW THE LAND LIES
Page No. 22
Nonwoven Bulletin Volume 01 Issue No. 05 / February 2015
he world‘s largest artificial island, the biggest-ever land reclamation project, and even the
most prized ski slopes in the Swiss Alps all rely on layers of nonwoven fabrics for their
stability. In infrastructure projects around the world, permeable geotextiles – typically
made from polypropylene or polyester – have a range of functions to perform in respect of
separation, filtration, reinforcement, protection or drainage. Construction teams have
employed them for decades where stone is used as the base for roads and railway lines.
When stone is placed against indigenous soil there is always a danger of it becoming
contaminated or unstable as a result of both the relentless weight placed upon it over
years of traffic and of water movement through the soil. A geotextile layer beneath the
base of the stone allows the water to drain away but at the same time prevents instability
and contamination. Geosynthetics are also used extensively beneath coastal defences,
where a robust layer laid below rock armour or pre-cast concrete units ensures that the
underlying soils are not leached out by tidal action, undermining the whole structure. Two
extreme examples are Dubai‘s Palm Island Jumeirah and Hong Kong‘s International
Airport.
Dubai's coastline
Palm Island Jumeirah is the first of three islands that were initially planned to extend Dubai‘s coastline from 72 kilometres to a staggering 1,500 kilometres, being designed in elaborate patterns with extending ‗fronds‘. Work on the second island, however, Jebel Ali, has taken longer than initially planned and the construction of the third has now been shelved for the immediate future.But Palm Island Jumeirah was completed in 2007 at an estimated cost of $12.3 billion and having involved around 40,000 workers. It was created by pouring sand fill onto the deep seabed using dredgers and then by employing a technique known as ‗rainbowing‘, in which the sand fill was sprayed over the surface of the rising island. Palm Island Jumeirah now measures five square kilometres and has 17 fronds, each two kilometres long and 75 metres wide, which are protected by a 12 kilometre-long breakwater. It is the home to many different residential complexes and luxury hotels and also boasts the first monorail in the Middle East which connects the island to the mainland. Nonwoven geotextiles supplied by Fibertex of Denmark were widely employed in the construction of Palm Island Jumeirah, which in total employed some 90 million cubic metres of sand and rock. The engineered fabrics were used in the breakwater to separate the rock base from the sand ‗beach‘ and also under the roads on each of the fronds. In addition, they were used for landscaping and in the drainage and storm water sewers. As far as the breakwater was concerned, the selection of the geosynthetic material had to take into account the water depth, the wave height, the type of rocks that were to be dropped onto the fabric and the height from which they would be dropped. The material also had to resist puncture, be flexible enough to conform to irregular seabeds and be sufficiently porous to retain fine particles, while allowing the free flow of water. Page No. 23

Making Nonwovens from Pineapples, Piñatex is a sustainable, leather
alternative

Social entrepreneur and designer Dr. Carmen Hijosa founded Ananas Anam in 2011. She
owned her own leather goods company from 1978-1995, and it was in the 1990s while
working as a consultant to the Product Development and Design Center of the Philippines
when she discovered the qualities of pineapple leaf fibers, including their fineness and
strength. After this realization, Hijosa examined ways the fibers could be used to develop
an alternative material. ―The nonwoven industry became the bridge and tool to make this
transformation possible,‖ she says. Piñatex was initially developed in the Philippines, but
much of the research and development is being done in the U.K. and Spain, where the
finishing technology is being enhanced, Hijosa explains. While the product is eco-
friendly in that it‘s a leather alternative (the leather making process uses a considerable
amount of energy as well as chemicals, among other hazards), the Piñatex converting
process shows additional sustainable features
Nonwovens for Fido , Man's best friend gets groomed with wipes
Wet wipes offer much convenience—even for our furry friends. While wipes for pets have been around for more than 20 years, companies have introduced a number of applications in which to use them. Here‘s a look at a few companies that have left a big ―paw-print‖ on the industry. Petkin Petkin was founded in 1989 when its founder David Goldberg was looking for an easy way to keep pets clean without giving them a bath. The idea for using moist wipes seemed natural, and, according to the company, the very first brand of pet wipes was born. ―Our first two pet wipes were called Doggywipes and Kittywipes and were packaged in individual packets,‖ says Goldberg. ―These same wipes still exist today and are packed in flow packs.‖ The company claims to have the largest assortment of pet wipes in the world, and they can be used on dogs, cats, small animals and even on people. ―We‘ve got pets covered from head to tail and in between,‖ adds Goldberg. Current product offerings include Petwipes, Ear Wipes, Eye Wipes, Tooth Wipes, Itch Wipes, Paw Wipes, Tushie Wipes, Flea Wipes, Pet Stain Wipes and Sunscreen Wipes. The wipes are made of a spunlace rayon/pulp for the company‘s original line and bamboo fiber for its new bamboo line. Petkin‘s Bamboo line is made of 100% organically grown bamboo; a completely renewable resource. By incorporating bamboo in its products, the company says it‘s able to ―reduce the environmental effects of deforestation and provide a superior and sustainable product.‖ Another nonwoven offered in Petkin‘s Bamboo line is its Pottypads. According to its website, the Pottypads feature a quick drying, tear resistant top sheet, an absorbent layer, a ―triple action‖ super absorbent bamboo core that includes superabsorbent polymers, an extra absorbent layer and a plastic backing. www.petkin.com Page No. 24

Rohit Landge*, Aniket Bhute, Pradeep Ingale , "Dye Chem Pharma Business News", January 2015, Page Nos. 59 to 62
Abstract –
This paper gives a review for different natural variants used as eco-friendly finishing
treatment for textiles because huge need for antibacterial materials as growing public
health awareness formations caused by microorganisms, in many application areas like
apparels, medical devices, hygienic application, health care, water purification systems,
hospital, dental surgery equipment, food packaging, and all textile application which are
directly related to human contact. (1) Micro organisms causes skin infections, body odour
and decrease comfort value of garments. The microbial infestation is a common problem
especially in natural textiles due to their receptiveness for moisture, dirt, food particles
giving scope for microbe‘s growth. So by using these natural variants in finish on textiles
we will decrease the use of chemicals which used for antimicrobial finishes and make
finishing eco-friendly.
