In the line of fibre

Specialist nonwovens in the protective apparel market must provide comfortable clothing that can withstand hazardous working environments. A recent innovation is a breathable microporous film that can be laminated to a nonwoven substrate. Members of the protective clothing industry are trying to develop a standard for the US in order to i..

U. Engineering: New Developments for Nonwoven Machinery

U. Engineering Company Limited of Japan’s Caroliner fabric guiding and wrinkle removing device for woven and nonwoven fabrics, films, paper, and glass fabrics eliminates web expansion without damaging the fiber web. Rubber cords around the periphery of the wrinkle removing roll stretch and contract as the roll rotates to provide uniform ..

When cotton nonwovens become the vogue

Illustrated with colour photographs of a catwalk display and individual garments, this is an account of a fashion show that featured only nonwoven materials. Sponsored by Rieter Perfojet, with the concept “nonwovens as fashion items”, a team of designers took up the challenge, led by two experienced designers. No restrictions were place..

Improving wen evenness by using optimized feed webs (German) (Verbsserung der VliesgleiclumaBigkeit durch optimierte Speisevliese)

A Trutzschler tuft feeder for improving wet uniformity is described. The process is in four steps: consistent and continuous feeding; double truck principle; automatic adaptation of production; and web profile control.

Study of polypropylene-woollenised jute blended needle-punched non-wovens using a factorial design technique: Part 3

Physical properties studied were the effect of fabric weight and polypropylene proportion in polypropylene-woollenised jute blends on Breaking Elongation (transverse direction) at the level of 150 and 350 punches/Cm2 needling density on Initial Modulus (transverse direction) at the level of (a) 80:20::PP: W. J. blend, and (b) 350 punches/..

Reduced CV values in nonwoven fabric weights

Technological measures for levelling the fabric weight profile in the transverse direction have contributed substantial1y to reducing web irregularity. These alone are, however, insufficient to achieve optimum levelling. Longitudina1 profile uniformity maintained by the use of "Hyperpunch" in the needling process is necessary. Web weight ..

Nonwovens unit employs innovative vertical lapping system

Since the launch of the Wavemaker vertical lapped nonwovens line about two years ago by Santex AG Nonwoven, Switzer-land, eight commercial installations, have been constructed and installed. principally in Europe. The fundamental concept, of Czech origin, is described. The wide range of applications covered include shoe cushioning and mou..

Functional characteristics of modern microfilament nonwovens

Freudenberg Nonwovens has developed products with "textile characteristics" such as good draping properties. decorative appearance, good process ability and good " wash and wear" capabilities. "Evolon" fabric has been produced by a new process which consists of 100% continuous microfilaments with special characteristics. Various finishes ..

Breathable nonwoven/film composites produced by extrusion coating

Economic production concepts for greater competitiveness and meeting product demand more rapidly are becoming increasingly important for manufacturers of breathable composites. Raw material is the principal cost-saving possibility. A survey of endues applications in the marketplace is followed by an account of current market requirements ..

Nonwoven fabric bonding: Water jets or needles? (German) (Vliesstoffverfestigung: Wasserstrahl oder Nadel?)

An in depth comparison is made with the aid of tables between hydraulically entangled nonwovens and needled nonwovens, with regard to the economic aspects, fabric characteristics and processing conditions. The properties of hydraulically entangled products make them ideal for the rapidly expanding hygiene and medical sectors, where their ..
