Chemical Processing of 'Tencel' -- Wonder Fibre of Twenty First Century.

Courtaulds' high tenacity regenerated cellulosic fiber Tencel offers properties equal to or better than cotton. Tencel fiber properties include good wet and dry tenacity, good shrinkage properties, a fibrillated structure, resistance to chemcial and mechanical damage, and affinity for dyes. Tencel fabrics offer excellent and unique drape ..

Lyocell Fibers: Alternative Regenerated Cellulose Fibers.

Various processes manufacture cellulosic fibers without using environmentally polluting carbon bisulfide and ammonia. These processes incude the commercially viable N-methylmorpholine N-oxide (NMMO) process and the carbamate process, which is still in development. The NMMO process uses tertiary aminoxides as a solvent, reduces the number ..

Lyocell Fibers.

The manufacture of lyocell fibers, or alternative regenerated cellulosic fibers, via organic solvent spinning represents an important alternative to conventional cellulosic fiber processes that are significantly less safe for the environment. Other alternative processes, particularly the carbamate process, are still in the pilot or experi..

Improving Cotton's Spinning Value.

The market value of cotton is based on grade, staple length, and fiber fineness. Grade has the greatest impact on cotton price and is important to spinning mills. Other important factoors in yarn spinning include fiber length, length distribution, short f

ITMF Report.

The 1995 International Textile Manufactureres Federation (ITMF) survey on cotton contamination, stickiness, and seed coat fragments showed that contamination varied from region to region. Only 4 percent of spinners reported contamination problems in Austr

Plasticising of Textile Adhesives.

A review of thermoplastic adhesivs used in apparel manufacture focuses on their modification via plasticization for use in bonding and doubling fabrics. Waxes obtained by polyethylene waste pyrolysis have applications as plasticizers for polyethylene adhesives. A wax admixture of approximately 1-5 percent lowers the melting temperature of..

Extraction of Cotton Impurities: Supercritical CO(2) vs. Soxhlet/TCE.

Researchers investigated several extraction methods for removing residual natural waxes and processing lubricants from cotton fibers, yarns, and fabrics. Conventional solvent extraction generates problems with environmental toxicity and cost. A modified quantitative supercritical fluid extraction mehtod removed wax and oil impurities as w..

Application of the Part-Fibre-Bundle Theory nd Fibre Testing to Analysis of Cotton Yarns.

Part fiber bundle, a statistical modeling procedure based on the deformation of an individual fiber with random position and initial state in a flat fiber bundle, predicts the total tensional loading and breaking process of different flat fiber bundles an
