摘　　要：针对当前大麻/黄麻交织物粗糙刚硬,刺痒感明显及碱煮氯漂过程污染环境等问题,采用焦磷酸钠和复合酶(漆酶/酸性木聚糖酶复配)联合工艺对大麻/黄麻交织物进行处理,以织物质量减少率、织物断裂强力(经向)、弯曲长度、芯吸高度为指标进行单因子和正交优化试验,并进行了方差分析。得出最佳处理工艺方案:焦磷酸钠质量浓度为9 g/L,处理时间为90 min,处理温度为80℃,漆酶质量浓度为7.5 g/L,酸性木聚糖酶质量浓度为6.0 g/L,处理时间90 min,处理液pH值5.0。此时织物质量减少率为18.26%,织物断裂强力(经向)为780 N,织物弯曲长度较未经处理下降了24.82%,芯吸高度提高了46.4%,该工艺可达到碱煮氯漂(或碱氧一浴)效果,生态环保。The hemp/jute interlaced fabric is stiff in handle and polluted in alkali boiling chlorine bleaching.It is proposed to combined process with the sodium pyrophosphate and composite enzyme(laccase/acidic xylanase),taking the fabric weight loss ratio,fabric tensile strength(warp direction),bending length and wicking height as evaluation index,the single factor experiments and orthogonal test.Under the above optimal scheme,carried out the infrared spectrum test and performance comparison of the fabrics treated.The optimal process scheme was obtained as follows:the mass concentration of sodium pyrophosphate was 9 g/L,the treatment time was 90 min,the treatment temperature was 80℃,the mass concentration of laccase was 7.5 g/L,the mass concentration of acid xylanase was 6.0 g/L,the treatment time was 90 min,and the pH value was 5.0.The results showed that under the optimum solution,the fabric weight loss ratio was 18.26%,fabric tensile strength(warp direction)was 780 N,bending length reduced 24.82%,capillary effect increased 46.4%;the process can achieve the effect of alkali boiling chlorine bleaching(or alkali oxygen one bath),ecological and environmental protection,which has the potential of market development.
