摘　　要：采用亲电取代法合成反应型阴离子改性剂,对天丝织物进行阴离子化改性,再分别用黄连素和阳离子荧光红GN对改性天丝织物进行染色。探讨了改性剂用量对天丝织物抗紫外线和染色性能的影响,测试了染色织物的K/S值、UPF、紫外线透过率和染色牢度。结果表明:当天丝织物分别用黄连素或阳离子荧光红GN染色,相应最佳的改性剂质量分数为10%和15%。反应型阴离子改性剂有利于提高天丝织物的紫外线防护性能,染色织物的耐洗和耐摩擦色牢度达到3级以上。Reactive anion modification agent is prepared by electrophilic substitution reaction and is applied to tencel fabrics for anionic modification. Then the modified tencel fabrics are dyed with berberine and Cationic Fluorescent Red GN respectively. The effects of the modification agent concentration on the anti-UV and dyeing performances of tencel fabrics are researched. The K/S value, UPF, UV transmittance and color fastness of dyed fabrics are tested. The results show that when the tencel fabrics are dyed with berberine or Cationic Fluorescent Red GN, the corresponding mass fraction of modification agent is 10% or 15% respectively. The reactive anionic modifier can improve the UV protection performance of tencel fabrics. The color fastnesses to washing and rubbing are above Grade 3.
