微溶解处理对汉麻织物活性染料染色效果的影响

Influence of Micro-dissolution Treatment on Reactive Dyeing Effects of Hemp Fabric

探讨氯化锂/N,N-二甲基乙酰胺(LiCl/DMAC)微溶解处理对汉麻织物活性染料染色效果的影响。采用了不同工艺对汉麻织物进行微溶解处理,并进行活性染料染色,测定了试样的K/S值、耐摩擦色牢度,选择最优微溶解工艺,在此基础上对汉麻织物进行单因素实验和正交实验。结果表明,在单因素实验中,温度在65℃时上染效果最佳,碱用量在35 g/L时染色效果最好;在正交试验过程中,温度60℃、碱用量40 g/L时,染色效果最好,汉麻织物的力学性能较优。

The paper discusses the influence of micro-dissolution treatment in Lithium Chloride/N,NDimethylacetamide solution on the reactive dyeing effects of hemp fabric.Several different processes were adopted for micro-dissolution treatment of hemp fabric,and then the fabric was dyed with reactive dyes,the K/S values and color fastness to rubbing of the samples were tested,and the optimal microdissolution process was selected,and based on which,the single-factor experiment and orthogonal experiment were carried out.Finally,the results show that,in the single-factor experiment,the best dyeing effect appeared at about65℃and the alkali dosage is at35g/L;while in the orthogonal experiment,the best dyeing effect appeared at60℃and the alkali dosage is at40g/L;and the mechanical performance of the dyed fabric is also perfect at that time.
