摘要
通过向过氧化氢水溶液中加入漂白活化剂,可形成活化过氧化氢体系,产生更加活泼的过氧酸,对棉纤维在温和条件下进行漂白。N-[4-(三乙基铵甲撑)苯酰基]内酰胺氯化物(TBLC)是一类新型漂白活化剂,可以在低温、近中性条件下起作用。本文重点介绍了TBLC对过氧化氢的活化作用机理,在此基础上,提出了基于TBLC活化过氧化氢体系构建棉纤维低温漂白工艺的新思路,并对未来发展方向进行了展望。
An activated peroxide system is formed by adding bleach activator to an aqueous solution of hydrogen peroxide, from which peracid is generated as a more kinetically active bleaching agent and allows cotton fibers to be bleached under milder conditions. N-[4-（triethylammoniomethyl）benzoyl]lactam chlorides （TBLC） are a novel series of bleach activators which play the role of low-temperature bleaching under near- neutral conditions. In this paper, the bleaching mechanism of the TBLC-activated peroxide system was highlighted, based on which a new bleaching process was proposed for low-temperature bleaching of cotton fibers. This paper also provided new insights into the future development of low-temperature bleaching of cotton fibers.
