Abstract:

In order to improve the production efficiency and reduce energy consumption in bleaching of cotton woven fabric, a rapid pad-steam peroxide bleaching process was conducted by using a cationic bleach activator of (N-(4-(triethylammoniomethyl)benzoyl)caprolactam chloride (TBCC). Investigations were carried out to analyze the influences of alkalis, concentration of TBCC, steaming time and concentration of peroxide stabilizer by measuring the degree of whiteness and degree of polymerization of the bleached fabrics. It is found that the rapid pad-steam peroxide bleaching process could be optimized by using sodium citrate as pH regulator with a molar ratio of TBCC, hydrogen peroxide and sodium citrate in 1:1.2:1.4. The rapid pad-steam peroxide bleaching process is capable of shortening the steaming time to 4 mins or less, and raising the CIE whiteness index from 36.30% to 80.65%, but cause no apparent fiber damage.
