Erratum: Progress towards a greener textile industry^†

Abstract

Many of the principles of the relatively new science of Green Chemistry, which aims to use resources efficiently and minimise waste, are applicable in the field of textiles. Improving product quantity and reducing environmental impact in the production and subsequent coloration of textile fibres is a realistic goal. Public interest in organically produced natural fibres has followed on from that in organically grown food, although the market for organic fibres is still relatively small. In recent years, fibre manufacturers have played their part in introducing a number of more ecologically regenerated cellulosic fibres, as well as new totally synthetic polymer fibres based on renewable raw materials. The methods that can be adopted aimed at reducing the environmental impact of fibre, dye manufacture and subsequent coloration processes, are described with particular reference to these newer fibres.

A New Environmentally-Friendly Method of Dyeing Lyocell/Cotton Blended Fabrics

“…8 Lyocell fiber production is also more environmentally friendly than viscose rayon production, since the latter requires a large amount of water and control of sodium sulfate and toxic sulfide gases in their wastes. 9 Although lyocell fiber is very similar to cotton fiber, it has some significant advantages over other cellulosic fibers, including high dry and wet tenacity, and high wet modulus. Lyocell fiber has a higher breaking load and enhanced tenacity compared to cotton, due to its high crystalline/amorphous region ratio.…”

Synthesis of a Bi-functional Cationic Agent and its Application in Cotton Dyeing

“…Cationic modi cation of cotton to improve its dyeability with anionic dyes has received considerable attention for some time. [1][2][3][4][5][6] Pretreatment of cotton bers with cationic agents was reported to enhance the uptake of anionic dyes, resulting in no salt dyeings, reduced or no alkali use, reduced washing procedure, and high xation levels. 7,8 Various chemicals have been used for cationic modi cation of cotton bers.…”
