Lenzing's EUR 26 million sustainable nonwovens pilot facility

Edema stocking

Qmilk fibre

Meltblown technology for filtration applications

Currently most of the nonwoven products are produced using synthetic polymers. They cause land filling issue due to their non-decomposing nature. In order make biodegradable nonwoven products, Lenzing has invested EUR 26 million to commission a pilot scale one meter wide web technology in Austria. Wolfgang Plasser, Vice President of Global Business Management Nonwovens said that the new Lenzing Web Technology will enable the value chain to create more innovative applications out of the natural, biodegradable cellulose material.

Ohmatex in demark has developed an edema stocking with the aid of electronic smart textile technology. These smart edema stockings are used to measure the change in leg volume. This device helps to monitor the leg volume continuously using inbuilt sensors and sends this information to physicians via a telecommunication device. Hence, the number of outpatient visits to hospitals is reduced. This smart stocking can also be used to monitor women suffering from pre-eclampsia in pregnancy. This is a serious condition, which causes retention of fluid and can ultimately put the pregnancy at risk. The Edema stocking can be used to monitor the leg condition in both hospital as well as home environment.

In April 2011 the Qmilch GmbH was founded. There are now a group of companies – Qmilk IP GmbH, Qmilk Holding GmbH and Qmilk Deutschland GmbH – which are engaged in the production and development of biopolymers, based on milk proteins and other natural and renewable raw materials. It results from invention of Qmilk fibre. Qmilk fiber is made from milk, which is no longer suitable for internal consumption and would otherwise be disposed of as a secondary waste. Like wool and silk, Qmilk fibre is soft, gentle on the skin, and has antimicrobial, flame-resistant and non-allergenic properties. Due to this property the Qmilk fibre can be used as wipes. QMILK dissolves without residue in water and enables to meet the demands as a “flushable”.

Meltblown technology is one of the technologies to manufacture synthetic nonwoven fabrics. Meltblown fabric is generally used for filtration applications. The pore size of the meltblown fabric ranges from 5 – 40 µm. Smaller pores increase the filtration performance. However, it results in higher pressure losses. The size of the meltblown fibres used for filtration application lies between 200 and 2500 nm. Even though the fibre diameter is in nanoscale range, the filtration is not efficient to remove from air or liquid flows the finer particles. The filtration can however, be increased by means of electro charging. Here the nonwoven fabrics are electrically charged either by triboelectric charging or corona charging. The corona charging is prominently used for electro charging the fabric. Electro statically charging of nonwoven fabrics increases their filter performance at lower pressure drops. .

Interview of the Month

Krishnamurthy Vaidyanathan, Managing Director, BIOCRAFT

1. Brief write up on the profile of Biocraft.

Biocraft is the brain child of Mr. Krihsnamurthy, who is a second generation entrepreneur hailing from Tiruppur. Professionally he is an IT person with over 8 years of work experience at USA, which has prompted him to create a company that is future ready. A company that can add value to niche segments of the Indian markets was which is aspiring to be on par with the global benchmarks. The 3-year-old company specializes in creating products with antimicrobial component as the key USP. The company, which started as a small distribution firm for the world's cleanest, greenest and safest antimicrobial, has evolved into a full-fledged product development company.

2. What are the factors that helped you venture into the development and marketing of new generation antimicrobials?

3. What is unique about your product? Do a SWOT analysis of your product releation to the Strength/weakness/opportunities/threats the commercially available antimicrobials to prevent hospital-acquired infections.

4. What are the leading factors that helped you scale new heights in the realm of your business endeavour?

5. What are the opportunities for antimicrobial coatings despite antimicrobial resistant microbes?

6. How do you forecast the growth of the antimicrobial industry in the years ahead and what are the factors contributing to its growth?

The citizens of developed countries are so health conscious and environment conscious. However, the concept of BIO SAFETY is relatively new in India and is a very promising sunrise industry. Indians who have lived for long in the developed nations of the world, return back to their country and the stark reality of the Indian environment and its lack of BIO-SAFETY is being perceived as a serious threat and shortfall in the Indian environment. Hence, a high potential for products releated to bio-safety.

The antimicrobial products currently available in the market and catering to the healthcare segment are focussed on short-term solutions for a problem that has to be fought continuously from the point of human existence till the end of it. The manual component of this repetitive work is very high, as in, the same work has to be manually repeated multiple times a day and every day leading to a situation of complacency which will lead to serious lapses in this critical area of fighting Hospital Acquired Infection (HAI) . This leads to a huge vacuum for new technologies, products and developments, which can bring down this quantum of human interference into this work function. This is exactly the area where BIOCRAFT has launched a product that can bring down the quantum of human work by over 90%. Example a corridor that needs to be mopped with a disinfectant 3 times a day, 7 days a week works out to 21 mopping cycles. However, one single mopping with the BIOCARFT product can protect the floor from BACTERIA for 7 full days and more.

The leading factors are the cost efficiency in moving over to our product. The healthcare industries' constant efforts to keep HAI at minimum levels are another prime mover for creating a demand for our product. The product gives you a long term environment friendly solution with no equivalent in the market for its efficacy, sustainability or cost efficiencies. BIOCRAFT provides a holistic support in terms of training and handholding for the Healthcare management team to undergo the cultural change that is needed to adapt to this new approach and technology.

The bacteria killing component of the antimicrobials distributed by BIOCRAFT is physical by nature. This ELIMINATES the possibility of the

bacteria becoming antimicrobial resistant. To give an example, if a rat infestation is controlled by poison the rat starts identifying the threat then the smell component of the poison is built into the defensive mechanism within the DNA of the rat, However when a physical killing of the rat happens it can be done repeatedly and there is no possibility of the threat and its defence being built into the rat's DNA.

“SUNRISE INDUSTRY”, is the single word that can be used to define the ANTIMICROBIAL industry in India. Though a common buzzword within a healthcare infrastructure, Bacteria, Microbes and pathogens have become a common problem across many other Industries in India. Bacteria play a major role in spoiling the indoor air quality of a built environment, they cause body odours in garments, they play

havoc with food logistics industry and also in the food production industry. Technically speaking, the growth of ANTIMICROBIAL industry is limited only by the creativity levels of the individuals who hold such a product. The disruptive technology of the antimicrobial product marketed by BIOCRAFT, exponentially increases the possibilities of using the product to enhance the overall BIO-SAFETY of the Indian environment and employment hazards.

Newly Installed Instrument at CoE

Fabric touch properties are extremely important for apparel and textile industry. Studies on fabric hand properties have been conducted for many years. However, none of the currently available testing instrument address simultaneous measurements on different aspects of fabric touch. The Fabric Touch Tester (FTT) simultaneously measures physical properties related to touch feels of textiles such as knitted and woven fabrics in four modules as following.

1. Compression 2. Thermal 3. Bending 4. Surface Friction

The comprehensive, sophisticated design of the FTT enables it to measure all the mechanical and surface properties of fabric in one simple test.

FTT primary hand values illustrate the predicted touch/hand feels of samples. The higher value of fabric primary touch/hand – smoothness means a smoother surface; the higher value of fabric primary touch/hand – softness means a softer sample; and the higher value of fabric primary touch/hand – warmness hand means a warmer sample. Primary touch feels mean the feeling when contact samples passively, i.e. wearing. Primary hand feels mean the feeling when contact samples actively, i.e. hand evaluation. FTT therefore test fabric physical properties on both surface side and bottom side. Results obtained from surface side are used to calculate hand feels while those from bottom side are used for touch feels. Total comforts under both circumstances are evaluated as well.

SITRA has recently installed this equipment in its CoE Physical testing laboratory. Mills are invited to send their fabric samples to test the touch properties.

Know This Product - Face Masks

In the operating room the main use of surgical face masks is to protect the medical professionals from byproducts of surgical procedures such as bone chips, splashes of body fluids, and smoke plume resulting from laser or electrosurgical techniques.

Outside of the operating room, masks are used for standard precautions to protect clinicians and patients from pathogens that may spread by blood or other body fluids, secretions, or excretions. Surgical masks are effective against droplet transmission.

The design of the surgical masks and the number of plies in it depends on the end use. Usually, the surgical face masks are 3 ply (3 layers). This 3 ply material is made from a melt-blown material placed between the spun bond non-woven fabrics. The melt blown material acts as a filter preventing the microbes from entering into the mask as well as exiting from the mask. Most surgical masks have pleats or
