MANAGEMENT

Detailed explanation-1: -Bleaching, a process of whitening fabric by removal of natural colour, such as the tan of linen, is usually carried out by means of chemicals selected according to the chemical composition of the fibre. Chemical bleaching is usually accomplished by oxidation, destroying colour by…

Detailed explanation-2: -Chlorine, sodium hypochlorite, calcium hypochlorite, and hydrogen peroxide are commonly used as bleaches.

Detailed explanation-3: -Bleaching of fiber is effective at removing surface impurities, lignin and hemicellulose, thereby producing brighter color and rougher fiber surface which promotes fiber/matrix adhesion as depicted by SEM micrographs.

Detailed explanation-4: -In case of oxidative bleaching, Chlorine is the basis for commonly used bleaching agents like sodium hypochlorite, bleaching powder and sodium chlorite. While, the non chlorine containing oxidative chemicals are hydrogen peroxide, sodium persulphate, sodium percarbonate, sodium perborate and peracetic acid.

Detailed explanation-5: -Scouring is the process of removing the impurities such as oil, fat, wax dust, and dirt from the textile material to make it hydrophilic. Bleaching is the chemical treatment for the removal of natural coloring matter from the fabric.
