PDMDAAC/AM在涤纶织物上的抗静电性能

研究二甲基二烯丙基氯化铵/丙烯酰胺共聚物(PDMDAAC/AM)在涤纶上抗静电性能。采用烘干和焙烘两种整理工艺对涤纶织物进行处理，进一步运用接触角测试仪、扫描电镜、X射线光电子能谱对其处理前后表面结构进行研究。实验结果表明PDMDAAC/AM在涤纶织物上具有很好的抗静电性能，并且表现出良好的耐洗性。良好的抗静电性能主要来源于聚合物在涤纶织物表面的附着。研究还发现两种工艺整理后，织物的抗静电性能和手感有一定的差异，主要是因为PDMDAAC/AM在高温焙烘下产生交联。

Antistatic properties of PDMDAAC/AM on polyester fabrics

Polyester fabrics were finished by p(dimethyldiallylammonium chloride/acrylamide)(PDMDAAC/AM) copolymer,followed by drying or curing,and the antistatic properties of the finished fabrics were investigated.The peak value,half life of the static voltage and antistatic durability after 20 washing cycles of the polyester fabrics before and after finishing were measured.Contact angle tester,SEM and X-ray photoelectron spectroscopy were applied to characterize the hydrophilicity,surface morphology and change of surface compositions of the polyester fabrics before and after finishing.The results indicated that PDMDAAC/AM attached on the surface of polyester fabrics imparted good antistatic properties and washing durability to the fabrics.In respect of antistatic properties and hand feeling,there existed some difference between the dried and cured polyester fabrics,which was attributed to the crosslinking of PDMDAAC/AM under high temperature curing.
