以蟹壳甲壳质为原料，以不同配比的氯化锂（ＬｉＣｌ）和Ｎ，Ｎ－二甲基乙酰胺（ＤＭＡＣ）以及三氯乙酸（ＴＣＡ）和二氯甲烷（ＤＣＭ）为复合溶剂制备了甲壳胺纤维的湿法纺丝原液（成纤高聚物的浓溶液），对原料溶解过程的预处理和纺丝原液的流变性能做了研究。结果表明，在ＤＭＡＣ／ＬｉＣｌ体系中，ＬｉＣｌ含量为８％时和ＴＣＡ／ＤＣＭ（Ｗ／Ｗ）为６０／４０时，甲壳胺的溶解性最佳。纺丝原液浓度在４～６％时，可纺性较好，而当浓度大于６．８％以后，可纺性变得很差。
Using chitin shell chitin as raw material, different proportions of lithium chloride (LiCl) and N, N-dimethylacetamide (DMAC) and trichloroacetic acid (TCA) and dichloromethane The wet spinning solution of chitosan fiber (concentrated solution of fiber-forming polymer) was used to study the pretreatment of the raw material dissolution process and the rheological properties of spinning dope. The results showed that chitosan had the best solubility in the DMAC / LiCl system when LiCl content was 8% and TCA / DCM (W / W) was 60/40. The spinnability was better when the concentration of spinning dope was between 4% and 6%, while the spinnability became worse when the concentration was more than 6.8%.
