The Red Batiks of Jambi: Questions of Provenance

This article is intended to shed light on the question of provenance of a group of batik cloths which are thought to have originated from Jambi in South America. As well as trying to solve this question it also seeks to unravel the history and circumstances behind the cloths which have given rise to differing opinions in published account..

River water means the bills don't soar

Reports on use of river water by two dyeing companies Westdale Dyeing, Leicester, England, UK and Langholm Dyeing, Dumfriesshire, Scotland, UK. Westdale uses 115,000 ㎡ of water a year and by drawing from a tributary of the River Soar is making savings on the previous ￡100,000 water bill. The water is filtered, softened and treated with ..

Control of dye concentration, pH. and temperature in dyeing processes

Dyeing processes are receiving growing attention in the textile industry because of the high demand for quality products. Commonly, dye concentration, pH, and temperature in the dyebath are the factors that most affect shade and coloration uniformity of dyed goods. To achieve quality assurance, control of dye concentration, pH, and temper..

Exhaust dyeable polypropylene fibres

In this contribution the influence of polypropylene (PP) fiber modification by modified polyethylene terephthalate (PET) and other additives on dyeing and colouristic properties of blend fibres were investigated. The paper describes the dyeing characteristics of modified PP fibres using the disperse dyes. Modified fibres were prepared fro..

Dyeing blended fabrics - the ultimate compromise?

The importance of blends in the global context, and the end-use popularity of specific blends are reviewed. Why right-first-time processing is more important in blend dyeing than in processing 100% content materials are explored. The aspects relevant to dyeing blends are highlighted. The use of computer color matching in dyeing blends and..

AquaChron rinsing technique on Venus jet dyeing machine

According to Sclavos, the AquaChron process improves the rinsing performance through a combination of precise process control (heating/cooling time, fabric and water management) and the patented, double-nozzle 'win Soft Flow' system which uses two nozzles per chamber to create an extended 'intensive zone' for bleaching, dyeing and rinsing..

Decolorisation of azo dyes with hydrogen peroxide catalysed by manganese protoporphyrins

Manganese protoporphyrin or mesoporphyrin derivatives catalysed the decolorisation of azo dyes by hydrogen peroxide under mild conditions, pH 8.0 and 25℃. The decolorisation rate was increased by the presence of manganese protoporphyrin or mesoporphyrin derivatives and was dependent upon the structures of the porphyrins and of the azo dy..

Single bath chemical processing of jute - an update

Combined chemical processing of jute products makes the process faster and reduces energy consumption. This review article examines combined scouring and dyeing with direct dyestuffs, single bath bleaching-dyeing, combined dyeing-finishing, and combined water repellent and anti-crease finish. Recommendations are given for different combin..

Heavy metal threat to cotton dyers

Metals - both heavy and alkaline earth-can effect the success of preparation, dyeing and washing off of cotton and blends. The metals come from the cotton substrate itself, not the water, and are a result of production demands and forced cultivation-ie geology and climate of crop growing area, chemicals used in the cultivation and use of ..

The jet age downs at ITMA

ITMA 99 was the 'coming of age' of ink-jet printing for the textile industry, with over 20 booths exhibiting digital printing systems based on all three of the major ink-jet technologies. Ink-jet printing requires a large number of relatively slow machines to produce volumes of fabric, and the technology still requires improvements in rel..
