Interview with Dave Rousse

The increased usage of antibiotic products like disinfecting wipes for minor infections have made bacteria stronger. This causes a problem for doctors to cure major infections. They may spread bacteria. Please present your views on this.

We have not seen evidence of disinfecting wipes causing problems, rather they have contributed to more sanitary living conditions. To the extent that bacteria adapt to various disinfectant chemicals, new ones are being created. The issue of superbugs in hospitals IS an area of concern. The only safe practice for any open-tissue procedure is to utilize disposable gloves, masks, drapes, gowns, etc. Using these items once, and then incinerating them, is a proven practice to avoid bacteria spread. This disposal practice is sometimes counter to local cultures and practices. However, we see that all doctors coming out of medical school all over the world are understanding the need and effectiveness on using disposable nonwoven products to reduce infections; they just need to convince the funders.

There is lot of energy consumed while recycling of disposables. How can that be reduced

Closed loop manufacturing processes can cut energy consumption, as can the aggressive search for recycled product sources closer to point of use.

What is the percentage share of nonwovens, round the globe, produced by different types of technology?

While carded technologies have lost share their combined volume continues to rise boosted primarily by the spunlaced and needlepunched technologies. The spunlaid technology has increased at a faster pace, though, and surpassed carded in 2006. In 2012, it is estimated spunlaid’s share of web forming processes was 46% and carded’s 44%. Both airlaid’s and wetlaid’s share has remained relatively constant over the last decade at 6% and 4% respectively.

Do you think nonwovens can replace the wovens? To what extent this is possible?

Except in some specialized uses, nonwovens do not represent a threat to wovens at all. Woven fabrics have such a rich variety of textures, colors, patterns, weights that are both visually and tactically appealing. Nonwovens will primarily be limited to industrial clothing and/or single use protective clothing. Each has its own functional niche; I don’t see them as threatening each other at all.

Tell us about role of bi-component fibres in the field of nonwovens.

Bi-component fibers, the inclusion of two different materials in a single fiber strand, have tremendous opportunity. Currently, fabrics made with a polypropylene core for strength and a polyethylene sheath for softness have found utility in the diaper area, where the softness next to a baby’s skin is valued. Other resins and other configurations of the bi-component process besides core/sheath will yield other beneficial effects. This area is a great example of the robust nature of nonwovens to be engineered to meet a wide variety of technical needs, depending on the end-use. So we see this area continuing to deliver innovative nonwoven engineered fabrics.
