In this video, I am discussing the bleaching process.
Objectives of bleaching process:

The main objective of the bleaching process is to remove the natural colours and pigments present in the cotton fabric, yarn, and fibres.

To whiten the fabric.

If the scoured fabric contains natural colours and pigments, the brightness of the shade, absorbency of the cotton, uneven shade result after dyeing.

Pastel shades do not appear prominently on the fabric if the fabric has traces of natural colours and pigments.

Bleaching process:

Bleaching is the last process of textile wet processing.

The removal of natural colours and pigments present in the cotton by treating the material with bleaching agents is called the “bleaching process” the natural colours and pigments get disappeared from the cotton after bleaching and whiteness in the material results.

Types of bleaching:

There are two kinds of bleaching carried out;

Bleaching by the oxidation process
