NPCA was a non-formaldehyde multifunctional crosslinking polymer. The cotton fabrics dyed with 8.0%(owf)Vinylsulpone-type dyes were treated with 3.0%4.0% NPCA, 0.5 mol/L potassium thiocyanate as a catalyst, then padded through two dips and two nips to reach a wet pickup of 80%85%, then dried at 80℃ for 2 minutes and cured in oven at 140150℃ for 3 minutes. Crocking fastness and fixation (%) were improved with up to 1.01.5 units, 35%50%, respectively. And there was little difference between the color yield of dyed fabrics before and after the treatment at certain conditions. The possible crosslinking mechanism of NPCA was also investigated. It was concluded that NPCA can improve colorfastness of cotton fabric by means of the three-dimensional network, covalent bonding and other molecular forces.展开更多
为实现棉织物的高效抗菌,以氯苯咪唑为抗菌剂对棉织物进行抗菌整理,比较了轧烘焙、电子束辐照及等离子体预处理等方式对棉织物抗菌性能的影响。将整理剂质量分数、浸泡时间以及辐照剂量作为影响因素进行试验,得到电子束辐照的优化工艺...为实现棉织物的高效抗菌,以氯苯咪唑为抗菌剂对棉织物进行抗菌整理,比较了轧烘焙、电子束辐照及等离子体预处理等方式对棉织物抗菌性能的影响。将整理剂质量分数、浸泡时间以及辐照剂量作为影响因素进行试验,得到电子束辐照的优化工艺条件为:整理剂质量分数15%、浸泡时间60 min、辐照剂量65 k Gy。对经轧烘焙工艺、电子束辐照工艺(EB工艺)、基于等离子体预处理的电子束辐照工艺(P-EB工艺)整理的棉织物进行表面形貌观察、红外光谱表征、抗菌性能及其耐洗牢度测试、断裂强力及白度测试。结果表明:3种工艺整理的棉织物均有效接枝氯苯咪唑,经P-EB整理的棉织物抗菌性能最优,并具有优异的耐洗牢度,且织物强力及白度均满足服用要求。展开更多
