The environmental issues associated with residual colour in textile efnuents have posed a major challenge to environmental scientists as well as the textile colouration processors. The requirements to remove colour from textile efnuent on si te prior to discharge to sewer have been progressively tightened due to increased public complaints about coloured watercourses. Dyes are highly dispersibl...

The present study focuses on the improvement in the effluent treatment for the effluent generated from a cotton textile industry employing three reactive dyeing methods viz., Exhaust method, Pad-Dry-Cure method, and Pad-Batch method. Stabilisation pond, aeration tank, and aerobic biological treatment (using E-Coli type bacteria) are simulated in the laboratory in a series operation. Results rev...

Treatment of effluents containing phenols such as textile dyes with fungal laccases is usually limited to the acid to neutral pH range and moderate temperatures. Here we demonstrate for the first time that spore-bound laccases which are stable at high temperatures and pH values can be used for phenolic dye decolorisation. Laccase containing spores from Bacillus SF were immobilized on alumina pe...

Adsorption is one of the most promising decolorization techniques in dyeing wastewater treatment. Adsorption techniques for wastewater treatment have become more popular in recent years owing to their efficiency in the removal of pollutants too stable for biological methods. Dye adsorption is a result of two mechanisms (adsorption and ion exchange) and is influenced by many factors as dye/adsor...

17 The presence of dyes in wastewater effluent of textile industry is well documented. In 18 contrast, the endocrine disrupting effects of these dyes and wastewater effluent have been 19 poorly investigated. Herein, we studied twenty-three commercial dyes, usually used in the 20 textile industry, and extracts of blue jean textile wastewater samples were evaluated for their 21 agonistic and anta...

This paper discusses the performance modeling and availability analysis of Yarn Dyeing System of a Textile Industry. The Textile Industry is a complex and repairable engineering system. Yarn Dyeing System of Textile Industry consists of five subsystems arranged in series configuration. For performance modeling and analysis of availability, a performance evaluating model has been developed with ...

The textile industry uses different fibers obtained from various animals, of which the wool from domesticated sheep Ovis aries is commercially the most important. Dyeing is one of the most important finishing procedures of wool processing. It almost invariably involves absorption of water-soluble colorants from aqueous solutions by the fibers. Diffusion is the process by which the colorant mole...

The textile manufacturing industry consists of a wide range of occupations including spinning, weaving, knitting, dyeing and finishing of natural and synthetic fibres to produce fabrics, yarns and carpets. The range of exposures in the industry includes textile related dusts, chemicals used in making synthetic textiles, sizing agents, oil mist, dyes, solvents, crease-resistance agents, flame re...
