At the on-going spring edition of Intertextile Shanghai Apparel Fabrics, the Hong Kong Research Institute of Textiles and Apparel (HKRITA) is showcasing its newest range of functional fabric samples and recent developments in more eco-friendly textile production methods. The four projects include: high performance sportswear, chitosan yarns, thermal protective garments and solvent-assisted dyeing.
Sophie Huang, Research Officer – HKRITA, said, “The garments are a part of our on-going advanced textile production which provide wearers with added functionality in moisture management, lightweight, four-way stretch, and UV protection.”
It’s worth mentioning here that the range of performance garments by HKRITA were adopted by the Hong Kong rowing team during last year’s Olympic Games in Rio and has also recently been adopted by the Hong Kong marine police.
HKRITA is also highlighting its developments in more eco-friendly textile production methods – with wastewater treatment in solvent-assisted dyeing at the forefront of the company’s sustainability programme. The new technique involves the use of a micellar system with silicon-based green solvents, eliminating the use of water, as the dyeing medium. The solvent speeds up the dyeing process which is said to reduce water consumption to the great extent.
“There are other advantages to this technique,” Huang said, adding, “Unlike traditional water baths, solvent-assisted dyeing requires no pre-treatment and no salt, and the solvent can be recovered by distillation to reuse.”
