The New zealand research Effort to Increase the Value of Wool .

Strategies developed by the Wool Research Organization of New Zealand (WRONZ) to assist the New Zealand wool industry and increase wool prices include research and development and brandname identification. New technologies developed by WRONZ include Lanalbin APB antiphotobleaching agent for carpets, Languard zero effluent insect resistanc..

Evaluating Staple Fiber Processing Propensity. Part II: Processing Propensity of Polyester/Cotton Blends.

Researchers analyzed the fiber processing propensity of polyester fibers and cotton/polyester blends using a modified rotor ring spinning system. Polyester fibers had a different processing behavior than did cotton fibers on the rotor system. Different kinds of polyester fibers behaved differently during processing. The processing propens..

Cotton--From Stronger and Longer to Color and Blends, Directly from the Fields.

Major advances in cotton biotechnology are expected to be complemented by agricultural improvements (longer and stronger fibers) in the 21st century. Improvements in these characteristics will make cotton fibers easier to process. Better insect control inherent in the plant will result in better yields. New technologies, especially in dye..

Tendencies in Baling and Wrapping of Fiber Bales.

An overview of recent developments in fiber baling addresses the standardization of bale dimensions, development of pressing force, automation of bale wrapping, standardization of wrapping methods, automatic bale strapping, and baling systems for several fiber lines. Trends indicate that the installation of highly automated system will co..

Dyeing of Chemically Modified Wool.

Graft copolymerization is a chemical modification of wool fibers that diffuses polymers into the internal structure of wool. Chemical methods for grafting onto wool fibers include initiation involving aliphatic azo compounds, hydroperoxides, percarbonates, persulfate, peroxydiphosphate, periodates, metal chelates, Fenton's reagents, and h..

The Rayon Fibre Process and Fibre Characteristics.

Rayon fibers are manmade fibers composed of regenerated cellulose and are chemically identical to cotton on a molecular level. The three rayon fiber manufacturing processes are the viscose, cuprammonium, and Tencel methods. The viscose method is the most widely used. The cuprammonium method, which is more expensive, serves niche markets f..

Eco-Friendly Cellulose Fibre Process.

An overview of lyocell fibers examines their extrusion, fibrillation, applications, blends, dyeing, finishing, and recent lyocell related activities at Courtaulds, Lenzing, and Akzo Nobel. The preparation of lyocell entails dissolving wood pulp in amine oxide, which is not toxic and is eventually purified and recycled. Compared with other..

Regenerated Silk Fibroin -- A Review.

This review of literature on the regeneration of silk polymer from silk waste covers classifications of silk waste; methods of separating silk polymer from silk waste; properties of silk fibroin powder, formation and properties of silk thin films; and applications of fibroin powder, silk, fiber based materials, films, and membranes. Table..

Structural Changes in Silk Fibers by Steaming.

Researchers used wide angle X-ray scattering to study the changes in raw silk fiber structure caused by steaming Samples included mulberry silkworm (Bombyx mori), Chinese tussah silkworm (Antheraea pernyi), and Japanese oak silkworm (A. yamamai) fibers. Mulberry silk fibers became amorphous when steamed without tension, but retained cryst..

The Use of Flax and Hemp Materials for Insulating Buildings.

A review of the use of hemp and flax for building insulation focuses on the growing market for biogenic materials in environmentally safe construction. The review compares relevant physical properties of established biogenic materials with those of such conventional materials as glass wool and polystyrol. Materials based on flax yield the..
