中文摘要：

采用常压低温等离子体射流（APPJ）预处理结合碱性果胶酶对棉针织物进行精练，通过测试润湿时间、白度和强力，分析等离子体处理时间、喷嘴与织物距离（JTSD）、果胶酶处理时间、酶浓度等因素对果胶酶精练效果的影响，优化了APPJ预处理工艺（He／O220／0．2L／min，40W，60s，喷嘴与织物距离为2mm）和无助剂果胶酶处理工艺（Bioprep 3000L 300APSU／g织物，50℃，60min，pH值8．0）。经此工艺处理后，织物的润湿时间小于2S，强力保留率大于90％，达到传统碱精练处理效果。

英文摘要：

Alkaline pectinase scouring of cotton fabric is carried out combined with atmospheric pressure plasma jet （APPJ） pretreatment. The effects of APPJ treatment time, jet-to-substrate distance （JTSD）, pectinase concentration and enzyme treatment time on enzyme scouring results are discussed by determining wetting time, CIE whiteness and retained bursting strength. The optimum APPJ pretreatment process is He/O2 20/0.2. L/rain, 40 W, exposure time 60 s and JTSD 2. ram. The optimum pectinase scouring process is treating at 50 ℃ for 60 min with Bioprep 3000L 300 APSU/g fabric and pH value 8.0. The treated cotton fabric can obtain the same scouring results these with the traditienal scouring process with wetting time ef less than 2 s and strength retention of more than 90%.
