Studies in dyeing behaviour of microfilament yarns and fabrics. II

Polyester Microfibres are widely used in fashionable textiles but the small radius of the fibre causes problems with the dyeing process and colour fastness of the fabric. This article discusses these problems and explains the dyeing behaviour of microfibres. In this study polyester filament yarns of varying deniers were dyed in separate b..

Machinery, equipment and supplies

This is section of the buyer's guide published by the American Association of Textile Chemists and Colourists. It is guide to sources of machinery and equipment used in the dyehouse and laboratory for the dyeing and finishing of textiles. It is divided into two sections: machinery, equipment and supplies by company sources. The guide is a..

75 years of change in dyeing and finishing

Since the founding of AATCC in 1921, the industry has seen many changes. The end of World War I brought the realization that the US needed to develop chemical processes and manufacturing independent of Europe. The result has been a dedication to research and the development of new fibers, dyes, finishes, and equipment to process these new..

The Application of Membrane Technology for Reuse of Process Water and Minimisation of Waste Water in a Textile Washing Range.

A study investigated the recycling of process streams and the reduction of waste disposal using membrane technology in a continuous textile washing process after dyeing with reactive dyes. Researchers added membrane processing to a mathematical model of a

Effluent Study of Reactive Dyeing.

Researchers studied effluent parameters of reactive dyes at different temperatures. The study involved the measurement of dye uptake and effluent loads after dyeing cotton yarn with four reactive dyes at 60, 70, and 80 degrees centigrade. Temperatures of 60-80 degrees centigrade had no effect on dye uptake. Dyeing the samples with a 1 per..

Rope Dyeing Machine for all Types of Fabrics.

Argelich Termes y CIA SA's Technodye HT series of high temperature rope dyeing machines for both knit and woven fabrics operates at an average liquor ratio of 1:4. A programmable frequency converter controls delivery rate and pressure of the Technodye high pressure pump and allows dyeing of delicate fabrics as well as circulating speeds o..

Medusa Flowers 10: Rope Dyeing and Finishing Machine.

Maibo Company specializes in machinery for woven fabrics. Its Medusa Flowers 10 machine is designed for dyeing and finishing. Notable features of the Medusa Flowers 10 include anlack of pulling channels, which often causes jamming and cotting; more transfer points than conventional models; much less pull from the reel; a roller group betw..

PVA Treatment in Wastewater.

Polyvinyl alcohol (PVA) degradation in wastewater has been studied extensively. PVA degrades under the correct system conditions (low sludge loading, constant influx, and temperatures above 18 degrees centigrade) and does not degrade under other system co

Dyeing Behavior of Green Dyes in Coloration Process.

Despite developments in technology, the textile industry continues to generate a vast amount of waste. Researchers attempted to turn waste products into useful materials that can be utilized by the textile industry. Researchers investigated the appropriate methods of extracting color from waste effluent. They also used instrumental techni..

Effect of Laundering with a Bleach (Hydrogen Peroxide), Optical Brightener and a Softener on Cotton and Cotton/Polyester.

A study compared the effects of various laundering processes on 100 percent cotton and 70/30 cotton/polyester fabrics. Researchers bleached sample fabrics with hydrogen peroxide; hydrogen peroxide and an optical brightener; and hydrogen peroxide, an optic
