摘要
以甲基丙烯酸甲酯(MMA)和甲基丙烯酰氧基丙基三甲氧基硅烷(KH570)的共聚物作为涤纶切片的添加物,籍共聚物中的MMA组分赋予树脂流动性,籍KH570中的硅氧基团赋予抗熔滴性能。熔融指数和热失重分析表明,共聚温度为45℃、时间1.5 h下共聚物的流动性较好,不影响涤纶的纺丝性能。结果表明:共混涤纶纤维经水处理26 h后,无熔滴现象。
A new idea regarding improvement of anti-dripping property of PET fiber through adding the copolymer of MMA and KH570 to PET resin and then spinning is put forward.The MMA chain segment endows the fluidity of the copolymer and the cross linking siloxane endows the anti-dripping property of PET fiber.The experimental results show that the copolymer fluidity is adaptive to PET spinning when copolymer was obtained at 45℃,1.5 h,and the melting drop of PET fiber are not found after water treating 26 h.
