中文摘要：采用散纤维连续染色技术对黏胶散纤维进行连续浸渍染色后再冷堆固色,然后进行连续式水洗。分析了固色时间对黏胶纤维外观形貌、色泽指标及力学性能的影响,并对染色黏胶纤维成品的色牢度、pH和甲醛含量进行测试。结果表明:连续浸渍染色后的黏胶纤维,经冷堆24 h固色后,可获得较好的匀染性;染色黏胶纤维的力学性能略有下降,其中强度下降约15%,断裂伸长率下降约16%;染色黏胶纤维的各项色牢度、pH和甲醛含量均符合要求。

外文摘要：The viscose loose fibers are continuously exhaust dyed,followed by cold batching fixation and continuous washing.The effects of fixation time on the appearance,color index and mechanical properties of viscose fiber are analyzed,and the color fastness,pH and formaldehyde content of dyed viscose fiber are tested.The results show that the viscose fiber after continuous exhaust dyeing can obtain better evenness after 24 h cold batching.The mechanical properties of the dyed viscose fibers decrease slightly,the strength decrease by about 15%and the elongation at break decrease by about 16%.The color fastness,pH and formaldehyde content of the dyed viscose fiber can meet the requirements of the standards.
