应用阳离子漂白活化剂的棉织物快速轧蒸漂白工艺
|
摘要
为提高棉织物漂白工艺效率,降低能耗,使用阳离子漂白活化剂N-(4-(三乙基铵甲撑)苯酰基)己内酰胺氯化物(TBCC)构建棉机织物的快速轧蒸漂白体系,对精练棉机织物进行轧蒸前处理。通过测试快速轧蒸漂白织物的白度和聚合度分析了碱剂、TBCC的质量浓度、汽蒸时间以及双氧水稳定剂用量对漂白效果的影响。结果表明,使用柠檬酸钠为pH调节剂,并控制TBCC、双氧水、柠檬酸钠的量比为1∶1.2∶1.4,可使快速轧蒸漂白工艺的漂白性能达到最佳。所构建的快速轧蒸漂白工艺可将汽蒸时间缩短至4 min以内,使棉机织物的CIE白度值由36.30%提高至80.65%,而织物纤维并没有受到显著损伤。
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.
