摘要/Abstract

摘要：

纺织品在使用过程中经常会沾染一些有色污渍，在家庭洗涤中使用普通洗涤配方很难将其有效去除。过氧化物经常被用于家庭洗涤中去除纺织品沾染的有色污渍，但需在较高温度下起作用。活化氧漂体系是通过向过氧化物溶液中加入漂白活化剂形成的漂白体系，能够在较低温度下将纺织品有色污渍有效去除。本文使用N-[4-（三乙基铵甲撑）苯酰基]己内酰胺氯化物（TBCC）和四乙酰乙二胺（TAED）为漂白活化剂构建活化氧漂体系，以十二烷基苯磺酸钠（SDBS）和十八烷基三甲基氯化铵（STAC）为表面活性剂，设计洗涤配方，研究其在室温近中性条件下去除纺织品有色污渍的性能。实验结果表明：表面活性剂自身不能有效去除纺织品有色污渍，但携带的离子电荷能够在一定程度上影响活化氧漂体系对纺织品有色污渍的去除性能，SDBS与TBCC活化氧漂体系组成的洗涤配方能够在室温近中性条件下有效去除纺织品上的有色污渍。

Abstract:

Textiles are often contaminated by coloring matters in daily use. It is difficult to remove these colored stains by using traditional household washing detergents. Peroxides can be used as bleaching agents to remove these colored stains from textiles, however, at relatively high temperatures. Activated peroxide systems are established by adding so-called bleach activators that can react with hydrogen peroxide released from peroxides to generate more kinetically active bleaching species that can break down colored stains at lower temperatures. In this paper, N-[4-（triethylammoniomethyl）benzoyl]caprolactam chloride （TBCC） and tetraacetylethylenediamine （TAED） were used as bleach activators to establish activated peroxide systems in which sodium dodecylbenzenesulfonate （SDBS） and stearyltrimethylammoium chloride （STAC） were added. The formula was designed, aiming to remove colored stains from textiles at room temperature. Morin and coffee were used to simulate the colored stains on textiles. In near-neutral conditions at room temperature, it was found that surfactants themselves could not remove colored stains from textiles, but the ionic charges on these surfactants could interact with the activated peroxide systems and affect their performance on removing colored stains. The formula of activated peroxide system based on TBCC and SDBS was able to effectively remove colored stains from textiles at room temperature. This study might contribute to developing effective household washing formulations for cleaning textiles stained with colored substances.
