Standard Scouring & Bleaching Process in textile Or SOP Of Scouring and Bleaching Of Knit Fabric According To Fiber Type

Scouring is so important factor in wet processing (dyeing). Different type of chemicals and their different dosing is used according to the nature of the different fiber. We are discussing the scouring and bleaching process in textiles according to fiber or fabric type. Here We sharing a table of different types of fiver and their scouring process.
