PA 6 BCF production and the Aquafil solution dyed system

Aquafil of Italy have developed the Alto Chroma system for solution dyed PA BCF for textile floorcoverings. In developing the yarn system, work has focused on three different areas: stabilizers, the cross section and the polymeric matrix. These in turn affect color retention, bleach resistance, stability to deformation and resistance to s..

High Temperature Heatsetting of Tubular Knitted Fabrics Containing Spandex.

Fleissner GmbH & Company's HT SteamSet hot air heat setting and relaxation system for tubular knit fabrics allows the fabric to shrink in a steaming and relaxing zone before using a special spreading device to feed it to the perforated drum. Feeding the fabric nto the system in a plaited form achieves the best results. The steam zone appl..

Use of dyes as fine chemicals in textile fibre application

The Indian dye industry constitutes the backbone of the country's textile industry and provides important links to many consuming industries contributing to the national economy. The industry is not only self-sufficient in providing essential dyestuffs for the user industries in India, including non-textiles, but it has also made a rapid ..

Reducing pollution and energy requirements in cotton dyeing

A process that introduces covalently bound cationic dye sites into the cotton fiber has been developed. It allows cotton to be dyed in an energy efficient, low-pollution manner by improving the affinity of existing commercial dyes for the fiber without the use of new or unfamiliar processing equipment. A significant increase in process pr..

Alternative approach to color appearance of textile materials with application to the wet/dry reflectance prediction

The color appearance of textile fibers is usually modeled via the Kubelka-Munk function, which has shortcomings, some of them being addressed by empirical corrections. Work has been undertaken to produce a more representative model for textile fabrics that would have adequate flexibility to changing conditions such as microfibers, blends,..
