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.
