Bleach Washing Problem

jeanspro_jeanspro

Bleach Washing Problem Bleach can be used to decolorize indigo from garments.  In this process a strong oxidative bleaching agent such as sodium hypochlorite or KMnO4 is added during the washing. De-colorization process is  usually more apparent depending on strength of the bleach liquor quantity, temperature and treatment time. It is preferable to have strong bleach with short treatment time. After bleach washing, there should be neutralization to minimize yellowing. Limitations of bleach washed in the below: Difficult to control in bleach processing time Bleach is harness chemicals so it…
