Influence of the Fiber Properties and the Finishing Conditions on the Migration in Cellulosic Materials.

During the pad-dry-fixation of cellulosic fabrics, dye migration occurs during intermediate drying. An experiment evaluated the relationship between migration, the water retention capacity of the cellulosic fabric, liquor application, and the conditions existing during both wet and dry processing. Dye migration was independent of the subs..

Modern Trends in Dyeing of Polyester and Cellulosic Fabrics and their Blends.

Technological developments in the continuous dyeing of polyester and cellulosic fabric and their belends have focused on cost control through increases in productivity and decreases in energy consumption, on the integration or right first time and Quick Response conepts, and on the improvement of environmental safety. A critical strategy ..

Future for Knit Finishing in the Uited Kingdom.

A greatly increased potential for import penetration and environmental pressures in the heartaland are major challenges facing the United Knigdom's knitting industry. Commission dyers and finishers of knit fabrics have had to become adept at dealing with fiber blends, natural fiber variations, dyeing with pigments, and applying finishes. ..

Towards the year 2000 - the state of wet processing

In recent years wet processing has encountered several restrictions, eg global competition, orders for small betches, the changing market climate, the containment of costs, and the requirement for invironmental protection. The ways in which these restrictions have been dealt with are enumerated and developments in drying, colouring substa..

Impriving energy efficiency in the textile sector: heat recovery from waste water

The paper discusses low-cost technology designed to improve the energy efficiency of existing traditionally inefficient machinery such as that used in the textile sector. The RCR heat exchanger is an apparatus which be used to recover heat in continous processes using hot water, such as washing, bleaching or rinsing after dyeing. Its effi..

Energy saving n the textile industry

In spain small and medium-size textile firms will have to work hard to achieve sufficient competitivity in the European Market. Prices are critical in this respect, and largely based on energy costs. Production must minimize energy expendture and also energy costs overall. Coteneration of mechanical energy and of heat from liquid or gaseo..

Colur removal from a dyestuff industry effluent using activated carbon

The objective of this study is to identify the best commercially-available activated carbon adsorbents for reoving colur from dye effluent. Effcets evaluated were dye type, adsorbent particle diameter, intial dye concentration, carbon loading, wastewater pH and temperature. Adsorption isotherms are developed for different dyes and represe..

A critical review of the treatments for decolourization of textile effluent

In the textile industry wet processing operations are the chief cause of water pollution. The removal of colour from, e.g. dyeing effluents, is a major concern. The effectiveness of decolourization treatments such as membrane filtration, ion exxhange, surfactant precipitation, asorption techniques and electrokinetic coagulation. These met..

In vestigationns into AOX pollution in waste water from the textile industry

The Insitut fur Textile-und Verfahrenstechnik (ITV) Denkendorf carried out fundamental research into the concentration and sources of AOX (adsorbale organi halogen compunds) in textile waste waters, based on data from 12 firms in Germany including 3 in the former GDR. AOX investigations were carried out on mixed waste water as a whole, wa..

Pre-drying textile fabrics with infrared radiation

A number of different fabrics were pre-dried in a pilotscale electric infrared oven, using tubular radiant heaters placed evenly above and below the web. For most of the fabrics, the degree of drying, for given conditions using both medium- and short-wave sources, was independent of the anture of the fibers and the material construction. ..
