New dyeing centrifuge (German)

Emil Muhlmann GmbH, Germany, has developed a new dyeing centrifuge under the name of Centri-Dye, which enables dyeing, bleaching, washing, finishing and centrifuging to be carried out in one machine. The centrifuge can be used for treating loose fibre or flock and yarn hanks. Most of the fibres currently used can be dyed by this process, ..

ATI Innovation Award: Gaston County Dyeing Machine Co. for its millennium piece dyeing machine

Developed primarily for dyeing specialty fabrics including warp knits, spandex blends and microfibers, the machine features a new cloth chamber and liquor circulation system that promotes tension-free cloth movement. Other innovations allow the user to combine process steps and quick fills to substantially reduce process cycle time.

Future is integrated and automated

ITMA '99 saw a number of innovations in yarn dyeing technology. As well as robotized handling, an integrated systems approach is evident in several innovations. New systems are an offer from Scholl, Then, Maibo, Thies and Bellini.

Dyeing and finishing for the 21st century

Themes highlighted at the recent congress of the International Federation of Associations of Textile Chemists and Colorists include higher fixation, reduced processing times, and better environmental performance. The congress, held in Copenhagen, attracted 260 delegates, and discussion centred around new dyes and chemicals, new machines a..

Fabric yellowing caused by citric acid as a crosslinking agent for cotton

Citric acid (CA), one of the polycarboxylic acids used as cross-linking agents for cotton, is cost-effective and environmentally friendly, but its tendency to discolor fabric is a major disadvantage for white fabrics. In this research, we investigate cotton fabric yellowing caused by citric acid at elevated temperatures. We find that yell..

Effects of fabric parameters on specular reflection of single-jersey knitted fabrics

This paper is concerned with the prediction of goniophotometric curves (distribution curves of specularly reflected light) based on our mathematical model developed earlier for single-jersey knitted fabrics made from monofilament yarns. The theory is extended to include fabrics from multifilament yarns. Four physical and optical parameter..

ITMA '99 innovations signpost future trends in finishing equipment.

A review of some of the most significant new developments from the successful textile machinery exhibition, ITMA '99, held June 1-10 in Paris, France. Technological innovations abounded in practically every area of the preparation, coloration, and finishing sequence. This article covers the principle developments of ink jets for productio..

Designing for a moving target

Longclose, UK, did not attend Paris ITMA '99, however it has a programme of continual development as shown in the Airsoft, Ventura Rapide and Ventura LS machines - with adaptations for processing man-made fibre fabrics and elastomerics. In both machines development has focussed on the nozzle and fabric transport systems with attention to ..

Colouring clothes

Review recent advances in apparel processing equipment including Flainox's NRP/Evolution 2000 with centrifuging set up for rapid unloading and automated handling; the 72075 J2N from Pellering Milnor Corp, USA which uses low speed extraction to provide high quality finishes; and Colorcombi drum dyeing series from Proll and Lohmann with its..

Present state and foreseeable development of dyeing technology (Spanish)

The article analyses the theoretical bases and practical steps which have led to technological advances in the chemical technology of the dyeing process. The dyeing industry at the end of the twentieth century is bound by two key concepts: 'right first time' and 'rapid response'. In addition environmental considerations have become very i..
