Plain Bleached Fabric
Purpose of bleaching:
The purpose of bleaching is to remove the natural pigments, impart the necessary whiteness to the fabric, and at the same time further remove the natural impurities that have not yet been removed from the scouring.
Mainly there are dip, drift and continuous rolling.
Immersion is the process of immersing the fabric in a bleaching bath for bleaching. The rinsing is to uniformly stack the fabric in the tank, and the rinsing liquid is continuously sprayed on the fabric by a pump. Dripping is a discontinuous production that is rarely used today. Continuous rolling is the bleaching of the fabric after being immersed in a large container or in other equipment for a period of time.
