What is "Bleaching" - Definition & Explanation

The process used to remove the natural colour of fibres to give a white base onto which dyes can be applied. Bleaching is not always necessary. Chlorine based chemicals are effective but not good from an environmental point of view so have been largely replaced by hydrogen peroxide.
A process of whitening fibers, yarns, or fabrics by removing the natural and artificial impurities to obtain clear whites for finished fabric, or in preparation for dyeing and finishing. The materials may be treated with chemicals or exposed to sun, air, and moisture.
Necessary process to remove the natural and artificial impurities in fabrics to obtain clear whites for even dyeing and printing. Bleaching with hydrogen peroxide is the most environmentally friendly way to whiten fabrics. Hydrogen peroxide can help produce a white fabric but not a bright white fabric.
The procedure, other than by scouring only, of improving the whiteness of a textile by decolourising it from the grey state, with or without the removal of the nature colouring matter or extraneous substances (or both).

NOTE:

The removal of colour from dyed or printed textiles is usually called stripping (q.v.).

The process of improving the whiteness of the yarn or fabric or fiber without or with removing its natural color.
Chemical treatment to brighten, whiten, purify, refine, and balance pulp fiber.
A procedure used to improve the whiteness of the textile by decolourising it from the grey state. This is generally done using peroxide or hypochlorite.
