摘　　要：为解决植物染料对竹浆纤维织物染色性能差的问题,采用漆酶催化五倍子染料生成有色化合物对竹浆纤维针织物进行染色,探究了染色工艺参数对染色效果的影响。为进一步提升染色深度和其他性能,对竹浆纤维织物进行羟丙基壳聚糖改性预处理,然后进行酶促染色。结果表明:当浴比1∶50,五倍子染料质量分数30%(omf),pH=4.5,染色温度40℃,染色时间8 h,漆酶浓度130 U/mL时,染色织物K/S值可达到7.35左右;织物经羟丙基壳聚糖改性,染色后K/S值可达10.73左右,此时织物的耐水洗性能、紫外线防护性能、抗氧化性能均有明显提高。To solve the problem of poor dyeing performance of bamboo viscose knitted fabric with plant dyes,laccase catalyzed gallnut dyes is used,and the influence of dyeing process parameters on the dyeing effect is studied.To further enhance the dyeing depth and other properties,bamboo viscose fabrics are modified with hydroxypropyl chitosan,followed by enzymatic dyeing.The results show that when the bath ratio is 1∶50,the concentration of gallnut dyes is 30%(omf),pH is 4.5,the dyeing temperature is 40℃,the dyeing time is 8 h,and the laccase concentration is 130 U/mL,the K/S value of the dyed fabric can reach about 7.35.The K/S value of fabric modified with hydroxypropyl chitosan and then dyed with laccase catalyzed gallnut dyes can reach about 10.73,and the washability,UV protection,as well as antioxidant properties of the fabric are significantly improved.
