植酸对羽毛角蛋白整理涤纶性能的影响

Effect of phytic acid on the properties of feather keratin finished polyester fabric

为提高羽毛角蛋白(FK)对涤纶织物的后整理效果及其耐久性,向FK整理液中添加了植酸(PA)组分,采用SEM和FTIR对整理前后涤纶织物的形貌和结构进行了表征,同时对比分析了PA对FK整理涤纶织物表面静态接触角、芯吸高度、抗静电性能的影响规律。此外,将整理的涤纶织物进行洗涤处理,测试了织物上FK的保留率。结果表明:PA组分的添加,可在涤纶织物表面引入磷酸根官能团,使得亲水性基团的数量增加,整理涤纶织物的芯吸高度与抗静电性提升,表面静态接触角下降;同时PA还提升了FK整理涤纶织物的耐久性,经相同工艺水洗后,FK的保留率仍高达89.20%,高于单一组分FK整理的涤纶织物。

In order to improve the finishing effect and durability of feather keratin(FK)on the polyester fabric,phytic acid(PA)was added into FK finishing solution.The morphology and structure of polyester fabrics before and after finishing were characterized by SEM and FTIR.Meanwhile,the effect of PA on the surface static contact angle,wicking height and antistatic property of the polyester fabrics finished by FK were investigated.Besides,the FK retention rate on the fabric was tested after the finished polyester fabric was washed.The results showed that the addition of PA introduced phosphate groups on the surface of polyester fabric,increasing the number of hydrophilic groups.Consequently,the wicking height and antistatic property of the finished polyester fabric were enhanced and the static contact angle of the surface was decreased.PA also improved the durability of the FK finished polyester fabric.After being washed by the same process,the FK retention on the fabric finished by adding PA was as high as 89.20%,higher than that of the polyester fabric finished only by FK.
