摘　　要：采用改性剂B对纯棉织物进行改性,用天然紫胶染料进行无媒染色,并对改性工艺和改性后的染色工艺进行了优化.结果表明,棉织物改性工艺为:改性剂B用量6%,改性p H=12,80℃浸渍40 min;染色工艺为:染料用量1%(omf),染色p H=4.7,80℃染色60 min.改性后棉织物的染色深度明显增加,耐摩擦色牢度和耐皂洗色牢度较好,兼具防紫外性能.Pure cotton fabric was modified by modifier B and then dyed with natural lac dye without any mordant, The modifying and dyeing processes were optimized. The optimal process was determined as follows： modifying with 6% of modifier B at 80 ℃ for 40 min under pH=12, dyeing with 1% （omf） lac dye at 80 ℃ for 60 min under pH=4.7. The color depth of modified cotton fabric was obviously improved, the color fastness to rubbing and soaping were good and had good anti-ultraviolet effect.
