摘要

A sequential two-stage bleaching process using peracetic acid followed by hydrogen peroxide has been developed specifically for jute and jute/cotton blend fabrics. A peracetic acid system is optimized for jute by the selection of suitable buffering and stabilizing agents. A superior bleaching effect is obtained by using TSPP as a stabilizer in the presence of a phosphate buffer, under mildly alkaline conditions (pH 8.0-8.5), whereby excellent fibre brightness may be achieved at temperatures as low as 40-60 deg. C.
