摘要

Bleaching process is the most important pretreatment. It should be carried out with no fault in order to achieve the complete absorbency and uniform degree of whiteness. The purpose of bleaching includes the removal of various natural, added or acquired impurities from the grey cloth as efficiently as possible with minimum or no damage to the fibre and leaving the fabrics in a perfectly white state. The damage to the cloth refers to decrease in tensile strength of fabric caused by lowering the degree of polymerization of the cellulose chains due to molecular chain break down. Bleaching can also be defined as a process of making the fabric whiter, regardless of whether the purification is carried out for the preparation of dyeing, printing or in the processing of goods to be finished as white.
