Studies to improve the functional properties of terry towel fabrics made from bicomponent yarn

NITRA has developed a method to produce terry towels, using a non-conventional manufacturing process, to improve its functional properties. In order to have a better towelling effect the area of fibre surface in each loop should be mximum, therefore the yarn should have minimum twist to achieve better quality, but sufficient strength for ..

High strength glass fibre improves impact and fatigue resistance

Owens Corning of Ohio, USA has developed a high strength glass fibre, ZenTron, which claims to offer a 15-50％ improvement of tensile strength compared with other standard and high strength glass fibres currently on the market. ZenTron fibres also improve impact resistance by as much as 50％, and enhance fatigue resistance. ZenTron has a ..

Polyolefin and the 10-Year Automobile.

As United States automobile manufacturers have steadily increased the standard for durability of an automobile engine and body, automotive fabric manufacturers have been asked to improve the durability of their products to match that longevity standard. S

Trevira High Tenacity Yarn for Airbags.

Hoechst's high tenacity Trevira polyester yarn is ideal for the manufacture of air bags. In this market, Trevira competes with nylon yarns. Hoechst has optimized Trevira's properties for this end use, minimized its price, and established recycling operations for both production waste and the product after use. Air bags manufactured from T..

Measurement of Resilience Properties of Carpet Yarn.

A research project at the University of Gent will develop a method to test the resilience of pile yarns. The technique will test these yarns after spinning and will constitute an important preliminary quality control procedure for carpet production. The first stage of the project will evaluate various methods of measuring viscoelastic pro..

Trevira High Tenacity Yarn for Airbags.

Hoechst recently introduced a Trevira high tenacity polyethylene terephthalate (PET) fiber that is especially suitable for air bag fabrics. The Trevira PET fiber will be available in two types. Trevira Type 726 will be sold in Europe. Both types of Trevira feature a lower specific heat, lower moisture absorption, lower water retaining cap..

The stress relaxation of wool at a high straining rate

The aim of this paper is to report a measuring technique which can be used to investigate the stress-relaxation behaviour of wool fibres from zero relaxation time onwards at high straining rates. Results were obtained on Lincoln and merino wool with a gauge length of 5 cm at a straining rate of 120000％/min(1m/s) and 10％ extension.

Contactless sensing for broken yarns

A coarse count yarn break detector has been developed by Dent Instrumentation of Colne, UK. The device uses optoelectronic contactless sensing and can be used for carpet yarns, tyre cords, glass fibres and, any heavy yarns being spun. Because less sensitivity is called for than with fine counts, the company says that it was possible to cr..
