Printing and dyeing processing technology of polylactic acid fabric

The invention relates to the technical field of textile, and discloses a printing and dyeing processing technology of a polylactic acid fabric. The printing and dyeing processing technology comprisesthe steps that polylactic acid fibers are prepared, specifically, polylactic acid is produced into filaments under a filament dissolving process, and the filaments are woven by a looped pile weft knitting machine to obtain the polylactic acid fabric. Under the conditions that the working temperature of enzyme desizing is controlled to be 70-82 DEG C, the working time is 15 min and the pH value is10, the mixed fabric is bleached, whiteness and fabric strength can still meet the requirements, the pretreatment effect of printing and dyeing processing in the whole process is better, and the efficiency is higher. 本发明涉及纺织技术领域，公开了一种聚乳酸织物的印染加工工艺，包括聚乳酸纤维的制备：在溶丝工艺下将聚乳酸生产成长丝，通过毛圈纬编机对所述长丝进行织造，得到所述聚乳酸织物。本发明通过在酶退浆的工作温度控制在70-82℃之间，工作时间为15min和pH＝10的条件下，对交织物进行漂白处理,白度和织物强力仍能达到要求，并且整个过程的印染加工的前处理的效果更好，效率更高。
