摘要

An attempt has been made to investigate a two-stage eco-friendly bleaching of jute with peracetic acid-hydrogen per- oxide as a substitute for the conventional sodium hypochlorite-hydrogen peroxide bleaching. A non-silicate organic stabi- lizer 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 strengih and abrasion resistance, and improved soft- ness compared to the conventional process. However, the problem of photoyellowing of.the fabric on photoexposure for long duration still persists.
