探讨了环氧氯丙烷对棉织物接枝改性的原理,通过实验分析了环氧氯丙烷对棉织物接枝的影响因素,测试了棉织物接枝前后的接枝率、强力和白度,结果表明:环氧氯丙烷与棉织物发生接枝反应后,重量增加,将接枝前后棉织物采用双氧水漂白,已接枝已漂白棉织物白度最高,同时接枝后其强力有所下降。

This paper probes the theory of graft modiifcation of epichlorohydrin on cotton fabrics, analyzes the inlfuence factors of the graft modiifcation of epichlorohydrin on cotton fabrics, and tests the grafting rates before and after the grafting, the strength and whiteness of cotton fabrics. The result indicates the weight of cotton fabrics increases after grafting, and the grafted cotton fabrics bleached with hydrogen peroxide is the whitest compared with them before grafting, meanwhile the strength of them decreases up to some point.

采用自制阳离子助剂WLS-20先将棉织物改性，然后用活性染料对改性棉织物进行无盐染色，最后采用新配制的WLS-20溶液或改性使用过的WLS-20残液对染色棉织物进行固色处理。通过与未改性棉织物传统活性染料有盐染色工艺的对比发现，WLS-20助剂既可作为棉织物的改性剂，实现活性染料无盐染色；又可作为固色剂，提高染色产品的色牢度；且可重复利用改性使用过的WLS-20残液对染色棉织物进行固色处理，其固色效果与新配制的WLS-20固色效果相当。

In this paper, cotton fabrics are modified by using self-made cationic modifier WLS-20, then reac-tive dyes are chosen to dye the modified cotton fabrics, at last, new prepared WLS-20 solution or WLS-20 solu-tion which has been used in modification process is applied in the fixation process of dyed modified cotton fabrics. Compared with the traditional dyeing process of reactive dyes in the presence of salt for unmodified cotton fabrics, it is found that WSL-20 can not only be used as modifier to realize dyeing without salt for reactive dyes, it also can be used as fixing agent to improve color fastness of fabrics; Meanwhile, it is found that WLS-20 solution can be reused, which means WLS-20 residual solution from modification process can be used in the fixation process a-gain, and the fixing effects are the same with that using new prepared WLS-20 solution in fixation process.

综述了目前仿酶金属配合物在棉织物H2O2低温催化漂白中的研究现状及发展趋势，重点介绍了金属卟啉配合物、金属酞菁配合物、希夫碱金属配合物、大环多胺金属配合物作为棉织物H2O2低温漂白仿酶催化剂的效果，并展望了仿酶金属配合物应用于棉织物低温漂白的应用前景。

The research status and development trend about the application of biomimetic metal complexes in the low-temperature hydrogen peroxide bleaching of cotton fabric were reviewed. The paper introduced the catalytic effects of metal porphyrin complexes, metal phthalocyanine complexes, schiff-base metal complexes and macrocyclic polyamine metal complexes, which were used as biomimetic catalysts in the low-temperature hydrogen peroxide bleaching of cotton fabric. Furthermore, the application perspective of biomimetic metal complexes in low-temperature bleaching of cotton fabric was prospected.

将明胶蛋白加入到磷酸氢二铵阻燃整理浴中,以柠檬酸为交联剂,次亚磷酸钠为催化剂,研究该复配阻燃体系中各助剂对棉织物阻燃性能的影响,评价该体系阻燃整理棉织物的阻燃性及其他物理机械性能。结果表明,明胶蛋白单独处理很难使棉织物获得良好的阻燃效果,但当其与磷酸氢二铵阻燃剂复配使用时,有助于进一步提高棉织物的阻燃效果及减少整理后棉织物的强力损失,但整理织物的白度和毛效有所降低。

Gelatin protein was added into the diammonium phosphateflame retardant finishing bath to investigate the effects of additives in the compounded flame retardant system, in which citric acid was crosslinker and sodium hypophosphiteacts as catalyst, on the flame retardant property of cotton fabric. And the flame retardantproperty as well as other physical and mechanical properties of the finished cotton fabric were evaluated. The results showed that it is very difficult for cotton fabric to get good flame retardant property just treated by gelatin protein.While it is conducive to further improve the flame retardant property and reduce the strength loss of the treated fabric with deduction of whiteness and capillary effect through compounded finishing of gelatin protein and diammonium phosphate.

用环氧氯丙烷、二甲胺、乙二胺合成了阳离子改性剂聚环氧氯丙烷-二甲胺，并将其用于棉织物的阳离子改性，然后用活性染料进行无盐染色．确定了阳离子改性剂对棉织物的最佳改性工艺及改性棉织物的染色工艺．结果表明，棉织物经改性后，可用于活性染料的无盐染色，上染率和固色率均高于常规染色．

The cationic modifier polyepichlorohydrin- dimethylamine was synthesized by epichlorohydrin, dimethylamine and ethylenediamine. It was applied in cationic modification of cotton fabric. Then the modified cotton fabric was salt- free dyed with reactive dyes. The optimal cationic modification of cotton fabric and dye-ing process of cationic agent modified cotton fabric were determined. The results showed that the modified cotton fabric could be applied in salt- free dyeing with reactive dyes. The exhaustion rate and fixation rate of modified fabric were higher than those of the traditional dyed fabric.
