摘　　要：采用PECH-amine对棉织物进行阳离子化改性,然后用反应型紫外线吸收剂UV-SUN CEL LIQ对改性棉织物进行无盐抗紫外整理,探讨了改性剂和氢氧化钠用量、改性温度和时间对改性棉织物抗紫外线性能的影响,测试了整理织物的UPF指数、紫外线透过率和耐洗性能。结果表明:当改性剂PECH-amine 10g/L,氢氧化钠10g/L,改性温度90℃,保温时间60min时,改性后棉织物用UV-SUN CEL LIQ 3%(owf)抗紫外线整理的UPF指数可达到75左右,经过30次标准水洗之后,其UPF指数仍可保持在65以上。Cationic modification was carried out for cotton fabrics with PECH-amine,and then reactive ultraviolet absorber UV-SUN CEL LIQ was used for salt-free anti-UV finishing of cotton fabric.The effects of the concentration of modification agent and sodium hydroxide,modification temperature and time on anti-UV performance of cotton fabrics were discussed.The UPF index,UV transmittance and washing fastness of treated fabrics were tested.The results showed that the UPF index of anti-UV finished fabrics could reach about 75 under reactive ultraviolet absorber LIQ 3%(owf),which was kept at 65 after 30 times of standard washing under the following conditions:modification agent PECH-amine 10g/L,sodium hydroxide 10g/L,modification temperature 90℃ and heat preservation time 60 min.
