合成了一种具有紫外线吸收性能的单体2-羟基-4-丙烯酯基二苯甲酮(HAB),采用传统的轧烘焙(PDC)方法将该紫外线吸收剂接枝到涤纶织物上,以改善织物的抗老化性能。探究了不同因素对接枝效果的影响。优化的整理工艺为:引发剂过氧化苯甲酰(BPO)质量浓度0.2%,紫外线吸收剂用量10%,50℃预烘5min后于120℃焙烘5min。整理织物的增重率达到(8.6±0.8)%。接枝后的织物用红外光谱和扫描电镜进行表征,并测试了抗老化性能。结果表明,整理织物的UPF(紫外线防护系数)达197±13,在紫外光照射300h后织物强力保留率为(60.5±3.6)%,较未整理织物提高了21.8%。
A kind of UV absorber HAB was synthesized and grafted onto polyester fabrics to improve the aging resistance with traditional pad-dry-curing method.The effect of different factors on the grafting results was investigated and weight gain can be reached at (8.6±0.8)% with the optimum finishing condition:0.2wt% of BPO,10wt% of UV absorber,curing 120℃,5 min after pre-dry 50℃,5min.The grafted fabrics were characterized by FT-IR spectra and SEM,and the auti-aging properties were also measured.UPF value of grafted fabrics was 197±13.The retention rate of breaking strength was (60.5±3.6)% after 300h under UV irradiation and increased with 21.8% compared with untreated samples.
