Abstract

Cotton is bleached with peracetic acid by varying the process parameters (pH, temper ature, treatment time, and acid concentration). The effect of these process parameters on the quality of the bleached material is discussed and compared with conventionally bleached materials. To obtain the desired degree of whiteness with minimum chemical damage to cellulose, the process parameters are optimized.
