真丝/PLA织物的染整工艺研究

摘要

以聚乳酸(PLA)长丝与桑蚕丝交织成的丝玉珠缎织物为研究对象,针对PLA纤维不耐强碱和高温的特点,对真丝/PLA织物的前处理、染色、热定形工艺参数等进行了研究,确定了适合真丝/PLA织物的酶练工艺、一浴法染中浅色和一浴两步法或二浴法染深色的染色方法、热定形等染整工艺参数,使真丝/PLA织物保持良好的风格及服用性能.%The satin perl made of the PLA fiber and the silk fiber was the object of the study. As the PLA fiber could not resist the alkali and high temperature, the process of the satin perl should be studied, including the pretreatment, dyeing and heat setting. The optimum dyeing and finishing parameters of the process of the fabric was researched by investigating the condition of proteinase refining, dyeing method and heat setting. One bath process was used to dye the neutral and light colors. And one bath two-stage process or two baths process was employed to dye the deep colors. The fabric style and good wearability were retained.
