【摘要】 在少量水存在下，将聚氧乙烯二胺（ＰＥＯ二胺）及Ｎ，Ｎ－二（３－氨丙基）甲胺（ＢＡＰＡ）与等摩尔的己二酸成盐后，再与己内酰胺共聚制得ＰＡ６－ＰＥＯ二胺－ＢＡＰＡ嵌段共聚物，然后将共聚物与ＰＥＴ切片进行共混熔融纺丝、拉伸，得到ＰＥＴ／ＰＡ６－ＰＥＯ二胺－ＢＡＰＡ共混改性纤维。研究发现，嵌段共聚物中低聚物含量少，改性纤维具有良好的可纺性、拉伸性及较高的强度保持值，共混纤维的抗静电性优良，还同时具有分散染料和酸性染料的可染性。对改性纤维进行季铵化处理后，可获得更加优越的抗静电效果。更多还原

【Abstract】 With a little amount of water, poly(oxyethylene)diglycolic amine(PEO diamine)and N,N-bis(3-aminopropyl)methyl amine (BAPA)formed salts with equal moles of adipic acid, then copolymerized with caprolactam and PA6-PEO diamine-BMA block copolymers were prepared. The block copolymer pellets were mixed with PET pellets, and the PET/PA6-PEO diamine-BAPA blend fiber was obtained by melt spinning and drawing. The spinnability and the drawability were quite good. The modified fibers had very good antistantic property while their tensile strength was close to that of PET fiber. The blend fibers could be dyed in disperse and acid dyeing systems,After the quaternary ammonium treatment,the modified fiber had much better antistaic property .更多还原
