Beschreibung
Zusammenfassung:The invention discloses a pre-treatment process for production of polylacticacid fiber fabric, and aims at a problem that strength of polylacticacid fiber is severely decreased at a high temperature and alkaline condition. Wide temperature biological enzyme is used for enzyme desizing, and bleaching technology is not needed; non-contact drying is used, and the temperature is controlled between 80-90 DEG C; setting temperature does not exceed 130 DEG Cx30 seconds. The pre-treatment process is used, and the polylactic acid fabric has the advantages of good strength and soft hand feeling; the performance of the fabric is preserved to the largest extent. 本发明公开了种聚乳酸纤维面料生产前处理工艺，针对聚乳酸纤维在高温、碱性条件下强力下降严重的问题，采用宽温生物酶退浆，无需漂白工艺；用无接触式烘干，温度控制在80～90℃之间；定形温度不宜超过130℃X30sec。采用该前处理工艺，能够使得聚乳酸纤维面料强度好，手感柔软，织物性能得到最大程度的保留。
