COURTAULDS STARTS COMMERCIAL PRODUCTION OF SOLVENT-SPUN CELLULOSIC FIBER

Courtaulds has begun commercial production of Tencel, a solvent-spun cellulosic staple. Tencel is stronger than rayon, both wet and dry, and is easily processed and dyed. The fiber is being spun at a plant in Mobile, Alabama, with a production capacity of 20,000 tons per year. Courtaulds has invested about 100 million Pounds Sterling duri..

FIBER BLENDS AND YARNS CONTAINING METAL FIBERS FOR TECHNICAL TEXTILES

Metal fibers, such as stainless steel fibers, can be blended for use in a variety of applications requiring antistatic properties. Their most improtant use in is industrial fabrics. These blends can be used in woven, nonwoven, braided, knit, and tufted fabrics. The metal fibers confer such properties as electrical and thermal conductivity..

TENCEL -- AN INNOVATIVE FIBER.

The properties, prudction, and global marketing of Tencel, an innovative, environmentally freindly fiber from Courtaulds, are discussed. Courtaulds introduced Tencel at a gala event in New Yrok City. At the event, 20 leading fashion designers and apparel manufacturers presented apparel made with Tencel. The fiber was later introduced and ..

RECYCLING OF TEXTILE WASTE INTO NONWOVENS PRODUCTS.

Newly developed nonwoven products can be manufactured from textile waste materials. Several processes used to manufacture these nonwoven fabrics are described. The operation of foam padders and mixers, dryers with IR preheating, perforated drum dryers, winding devices, and multipurpose lines for the production and bonding of waste fiber w..

CELLULOSE FIBER-REINFORCED POLYMER COMPOSITES -- EFFECT OF PLASMA MODIFICATION ON PROPERTIES

Chemical interactions between cellulose fibers and ionized gas plasmas during plasma modification are reviewed. Various reaction parameters are defined in an attempt to better understand how to modify a fiber's surface morphology to improve the adhesion between lignocellulosic fibers and synthetic plastics in reinforced composites. Abstra..

CONDUCTIVE POLYPROPYLENE

Courtaulds is not using Cabelec 3140, a polypropylene polymer loaded with carbon, to produce an electrically conductive polypropylene filament yarn. The yarns are part of a research and development project devoted to filled yarns. The conductive polypropylene filament yarn can be used in woven structures to eliminate static electricity. C..

HIGH TENACITY POLYESTER AND NYLON FILAMENT MARKETS IN NORTH AMERICA.

The most important North American market for both high-tenacity polyester filament yarns and high tenacity nylon filament yarns is the automotive market. Weak automotive sales since the late-1980s have damaged this market, but new automotive uses for high-tenacity yarns are emerging. The high-tenacity polyester and nylon markets for tires..

PHASE-SEPARATED MICROSTRUCTURE OF POLYETHER-POLYESTER BLOCK COPOLYMERS AND WETTABILITY OF THE POLYMER SURFACE.

A polyether-polyester block copolymer was produced from polyethylene terephthalate (hard segment) and polyethylene glycol or polytetramethylene glycol (soft segment). Its surface composition and wettability were investigated by measuring the contact angle of water droplets against the surface. The compositions of the hard and soft segment..

DIELECTRIC RELAXATION BEHAVIOR OF ABSORBED WATER ON AROMATIC POLYESTERS

Dielectric measurements were used to examine the state of absorbed water and its effects on aromatic polyesters. The measurements depended on the quantity of absorbed water, but not on temperature. The dipole moment of absorbed water was calculated from the dielectric increment, which showed that water was absorbed in the gas phase. 14 re..

INFLUENCE OF THE THERMAL PROCESS ON THE FINE STRUCTURE OF HEAT SET POLYESTER

Two substrates stabilized at different temperatures were heat-set at 150 and 200 degrees Centigrade, and characterized through pre-fusion endothermic peaks (PEP), percentage of crystallinity, and critical dissolution time (CDT). Although stabilization temperature influenced the percentage of crystallnity and CDT, it had little or no influ..
