摘　　要：探讨棉织物用自制阳离子改性剂WLS与双氧水进行同浴改性和漂白的可行性,优化一浴法改性漂白工艺,即改性剂WLS 20 g/L,碳酸钠9 g/L,硅酸钠2 g/L,30%双氧水15 g/L,漂白改性处理60 min。结果表明,改性剂WLS对双氧水漂白效果影响不大,用一浴法漂白改性的棉织物活性染料染色性能显著提高,耐摩擦色牢度和耐皂洗色牢度有所改进。The feasibility of modification of cotton fabric with a self-made cationic agent WLS and bleaching with hydrogen peroxide in one bath is carried out, the processing conditions are optimized as follows： cationic agent WLS 20 g/L, sodium carbonate 9 g/L, sodium silicate 2 g/L, 30% hydrogen peroxide 15 g/L, and treatment for 60 rain. Results show that cationic agent WLS has little effect on whiteness, dyeing behaviors of reactive dyes are greatly enhanced on modified cotton fabric, therefore, salt-free reactive dyeing is realized, the dyeings have good color fastness to rubbing and soaping.
