using chemical bleaching methods which use a wide range of chemicals such as peroxides, hypochlorites, chlorites, peracids, sulphites, bisulphites, borohydrides, etc. adopting biobleaching and biosoftening for wet processing of coir is an alternative to using hazardous chemical treatments. emulsions of oil
, fats and waxes, soaps, sulphonated oil, sulphated alcohols, fatty acid condensation products and quaternary ammonium compounds are the major classes of softening agents. the cheapest method for softening is alkaline treatment, which was effective to a certain extent, but was detrimental to the strength...

in preparation, the mill removes natural impurities or processing chemicals that interfere with dyeing, printing, and finishing. typical preparation treatments include desizing, scouring, and bleaching. preparation steps can also include processes, such as singeing and mercerizing, designed to chemically
or physically alter the fabric. for instance, the mercerizing stage chemically treats the fabric to increase fiber strength and dye affinity, or ability to pick up dyes. this, in turn, increases the longevity of fabric finishes applied during finishing. many of the pollutants from preparation result...
