摘　　要：用接枝剂A对棉织物阳离子化接枝改性 ,并研究其在涂料染色中的应用性能。试验结果表明 ,棉织物经接枝剂A改性后 ,改变了棉纤维对涂料的吸附能力 ,提高了涂料对纤维的上染率和K/S值 ;染色牢度均能提高 2级以上。该课题确定了接枝剂A对棉织物接枝改性的工艺条件 ,即NaOH浓度 3 % ,接枝温度70℃ ,接枝反应时间 2 0min ,接枝剂A浓度 3 % ,浴比 1∶3 0。Grafting agent A for cationic modification t o cotton fabric and its applied properties in pigment dyeing have been studied. Th e experiment results show that the absorption to pigments for cotton fabric trea ted by grafting agent A would be changed and dyeing rate and K/S value have been increased. In pigment dyeing the color fastness of cotton fabric modified w ith grafting agent A would be increased about two grades. The modified condition s of grafting agent A to cotton fabric are also decided, that is concentration o f sodium hydroxide 3%, grafting temperature 70 ℃, grafting time 20 minutes, liq uor ratio 1∶30.
