摘要/Abstract

摘要： 为提高靛蓝染料对纯棉牛仔布的上染率，本文以四氯化碳（CCl4）为溶剂，环氧氯丙烷(ECH)为合成单体，在催化剂三氟化硼合乙醚（BF3O( C2H5 )2）的作用下，预先聚合成聚环氧氯丙烷（PECH），然后再用二甲胺胺化制得靛蓝染色促进剂ZL，并对ZL对棉织物的改性工艺进行优化及其染色深度K/S值和色牢度进行测试。实验结果表明：ZL改性工艺参数为：ZL 2g/l，NaOH 4g/l，温度80℃，时间40min；改性后棉织物靛蓝染色耐洗牢度、摩擦牢度良好，K/S高达25.06，而相同染色条件下未改性棉织物的K/S仅为16.60。棉织物经改性剂ZL改性后，浸轧-氧化3次靛蓝染色就能达到未改性棉织物浸轧-氧化6次的染色效果。

Abstract: In order to improve the low rate of indigo uptake for cotton fabric, the cationic ring-opening polymerisation of epichlorohydrin in carbon tetrachloride with boron trifluorideetherate as catalyst produces the polyepichlorohydrin(PECH) polymer. ZL was prepared by the initial polymerisation of epichlorohydrin followed by amination with dimethylamine. And the modification conditions have been optimized, the K/S value and the color fastness had been measured. The condition was as follow：ZL 2g/l, NaOH 4 g/l, 80℃ and 40min. Cotton fabric modified by ZL had a significant increase in K/S value which could reach 25.06,while the unmodified was only 16.60. The experiments also showed that the same dye depth as that of 6-passage dyeing in traditional process could be obtained under the process of modification with 2 g/L ZL and 3-passage stock indigo dyeing. Meanwhile, the color fastness is also good.

Key words: modification, promoter ZL, indigo dyeing, K/S value
