摘要

As environmental awareness of textile wet processing's impact increases, attempts are being made to establish more environmentally benign textile processing. In this paper, a new combined process for desizing, bleaching, and scouring cotton in one bath is described using an innovative bleach activator, N-[4-(triethylammoniomethyl)benzoyl]butyrolactam chloride (TBBC) and alpha-amylase enzyme. TBBC reacts with hydrogen peroxide (H_2O_2) to generate a peracid that is a more kinetically active oxidant than perhydroxy anion, leading to effective bleaching at 50"C at near neutral pH. Data show that effective preparation, in terms of whiteness, and mote and size removal, was achieved. Also, while absorbency of the prepared fabric using the TBBC-based process was less than when conventional desizing, scouring, and bleaching was used, fabric strength was higher.
