聚马来酸(PMA)对竹纤维的抗皱整理研究

Study on Crease-resist Finishing of Bamboo Fabric by Polymaleic Acid(PMA)

以多元羧酸——聚马来酸(PMA)作为抗皱整理剂对竹纤维织物进行抗皱整理,讨论了整理剂用量、焙烘温度、焙烘时间对抗皱整理效果的影响,通过测试在不同整理条件下织物的折皱回复角、白度、断裂强力等性能取得了优化整理条件。整理后通过X-射线衍射和红外光谱对织物进行了一些结构和性能的测试,结果表明:整理剂在纤维无定形区大分子链之间发生了交联反应,提高了纤维的抗皱性能,纤维的晶区结构基本没有发生改变。

The crease-risist finishing of bamboo fabric by PMA was studied. The influence of PMA dosage, curing temperature and time on crease-resist effect of bamboo fabric was discussed. The optimal finishing process was obtained by testing the dry and wet crease recovery angles and the whiteness of fabrics treated under different conditions. The structure and properties of treated fabrics were studied by X-ray diffraction and infrared spectrum. The results show that the crosslinking reaction occurs between finishing agent and macromolecule chains in the uncrystallized region of fibers, which improves heat stability, while the crystallized structure has little change.
