New Trends in Yarn Carrier Design

The FLEX-Dia yarn carrier tube allows the dyed package to be used as the final package without back winding. The FLEX-Dia tube, similar to conventional cylindrical dyeing tubes in size, solves production management problems and maintains dye quality in automated production management systems. The FLEX-Dia's perforated surface facilitates ..

A Novel Route for Obtaining a 'Peach Skin Effect' on Lyocell and Its Blends

Researchers developed a one bath fibrillation, dyeing, and enzyme treatment for lyocell fabrics that reduces processing time by approximately 40 percent and consumes less water than conventional methods. A 6 hour pilot scale process dyed lyocell fabrics with reactive dyes based on the 3-carboxypyrimidino-1,3,5-triazine reactive group and ..

Effects of Different Quinoid Redox Mediators on the Anaerobic Reduction of Azo Dyes by Bacteria.

Researchers investigated the effects of adding different quinoid redox mediators to anaerobically incubated cultures of different species of bacteria on azo dye reduction. Anthraquinone-2-sulfonate (AQS) and 2-hydroxy-1,4-naphthoquinone (lawsone) resulted in the highest increase in azo dye reduction. Sphingomonas xenophaga BN6 and Escheri..
