P(AM-co-AA)浆料的共聚组成对其黏附性能的影响

Influence of copolymer composition on the adhesion of P(AM-co-AA) sizes

以轻浆粗纱条的最大强力、断裂伸长和断裂功为量化指标,研究了P(AM-co-AA)浆料的共聚组成对其上浆涤/棉纱黏附性能的影响。所研究的聚丙烯酸类浆料包括P(AM-co-AA)及其相应的均聚物PAM和PAA,它们都是用相应的单体通过自由基引发剂引发的聚合反应制备。实验结果表明,这些浆料的共聚组成对其上浆涤/棉纱的黏附性能有显著影响,P(AM-co-AA)浆料的黏附性能显著优于均聚物PAM和PAA。

The influences of copolymer composition on the adhesion of polyacrylic sizes to polyester/cotton yam are investigated by an impregnated roving method for warp sizing. The adhesion is evaluated in terms of the maximum strength, investigated include breaking elongation and work to break of a slightly sized roving. The polyacrylic sizes biopolymer of P（AM-co-AA） and homopolymers of PAA and PAM. The polymeric sizes were prepared through the that the adhesion of the polymerization of their corresponding monomers by free radical initiator. It was found polymeric sizes to the fibers is strongly depends on the type and amount of the structural units incorporated into the copolymer chains. The adhesion of the biopolymer sizes with appropriate ratio of AM to AA units on the fibers is superior to the homopolymers of PAM and PAA.
