精练酶 DMA 在牛仔经纱煮漂工艺探讨

摘要

Based on the orthogonal method, this paper analyzed the various factors of using enzyme DMA during denim warp scouring and bleaching. Compare with traditional denim warp scouring and bleaching method, enzyme DMA yarns shows higher whiteness, enhanced capillary efficiency, lower strength loss, low production cost and energy saving.%　　本文通过正交实验，分析 DMA 精练酶在牛仔经纱前处理中对各项指标的影响，通过实验发现与传统方法相比，使用 DMA 煮练的牛仔经纱具有白度高、毛效好、强力损失小、工艺成本低、节能环保等优点。
