Increasing dyeing and finishing for workwear fabrics

Due to increasing dyeing and finishing requests for workwear fabrics, factories in this industry have improved their operation rates. Some factories are reporting increases of up to 20% from the previous year's figures, and many are carrying out full-scale operations until the end of March 2000 in order to meet this demand. The substantia..

Emissions in the wool -processing textile finishing industry(AiF 11276)

Emissions in the finishing of wool fabrics and polyester/wool fabrics(stentering) are studied using headspace capillary gas chromatography/mass spectrometry. The results indicate that the emission of volatile organic compounds is at a minimum in the finishing of pure wool. There are no changes in the chemical composition after high temper..

ITMA 99 : Treatments prior to dyeing (Spanish) (ITMA '99 : Tratamientos previos a la tintura)

The article presents an overview of pre-dyeing treatments for yarns and fabrics presented at ITMA 99. The treatments presented are singeing, mercerization, ammonia finishing, de-sizing, scouring and bleaching. No great innovations were noted in these fields, but small modifications aimed particularly at improving economic and ecological a..

Nanofiltration membrane technology for caustic soda recovery

A process to recover a least 95% sodium hydroxide and water from textile mercerization wastewater has been developed using both laboratory and pilot scale nanofiltration membrane systems. Flux changes were measured in terms of operating temperature, filtration time, and sodium hydroxide concentrations. Pretreatment requirements as well as..

Reuse of polyamide and polyester mixed waste by addition of compatibilizer

Polyamid and polyester mixed waste carpeting is recycled for use in fabricating new carpeting and pile fabrics by adding a copolymer derived from an alkene monomer and an unsaturated epoxy-containing monomer as a compatibilizing agent. The mixture, e.g. of 75-90% polyamide, 10-25% of polyester and 5-20% of the copolymer, which may be a co..

New method for the mineralization of organohalogen compounds (German)

A new, free radical wet oxidation process for the mineralization of organohalogen compounds in waste water is described. It is a carrier-assisted system, with the carrier being a solid polymer having a reducing action(preferably a textile substrate). The oxidizing agent, managaness(IV) is firmly attached to this carrier. The redox system ..

Textile industry dye-house water recovery and reuse

This case study details a UK-based wool-dyeing and yarn-spinning company's quest for a suitable water recovery system which could offer economic benefits to its business and deal with its environmental constraints.
