A kind of polyether polyamide copolymer antistatic agent PED was synthesized by polycondensation through using hexamethylene diamine,adipic acid,polyether amine as raw materials and taking sodium hypophosphite as the catalyst.IR and 1 H-NMR were applied to characterize the molecular structure of PED,and it was applied for antistatic finishing of nylon fabric.The influences of PED dosage,curing temperature and curing time on the antistatic property of the treated fabrics were studied,and process conditions were optimized.Besides,the antistatic property of the finished fabrics was measured.The study results show that the optimal finishing process conditions of PED are as follows:PED dosage 20g/L,curing temperature170 ℃and curing time 50 s.The surface resistivity and induced voltage half-life of the finished fabric are 3.7×107Ωand 1.26 s,respectively.After washing 30 times,its surface resistivity and induced voltage half-life are 7.4×108Ωand 6.11 s.Compared with the finishing effect of common antistatic agent on the market,the finishing agent PED has good antistatic property and durability.
