Sequential bleaching of jute with eco-friendly peracetic acid and hydrogen peroxide

Abstract

An attempt has been made to investigate a two-stage eco-friendly bleaching of jute with peracetic acid-hydrogen peroxide as a substitute for the conventional sodium hypochlorite-hydrogen peroxide bleaching. A non-silicate organic stabilizer has been used in place of conventional sodium silicate in hydrogen peroxide bleaching. It is observed that peracetic acid-hydrogen peroxide bleaching gives higher whiteness, lower loss in strength and abrasion resistance, and improved softness compared to the conventional process. However, the problem of photoyellowing of the fabric on photoexposure for long duration still persists.
