【摘要】 将大直径聚丙烯(PP)、聚己内酰胺(PA6)、聚对苯二甲酸乙二醇酯(PET)、聚苯硫醚(PPS)单丝进行热处理,测试纤维的拉伸强度及勾结强度。数据表明:PP纤维的强损温度为120~130℃,PA6纤维的强损温度在150℃左右,PET纤维的强损温度为160~170℃,而PPS纤维的强损温度为220~230℃。因此PPS单丝的热稳定性优于其他几种聚合物单丝。更多还原

【Abstract】 The tensile strength and loop strength of the large diameter monofilaments of PP,PA6,PET,PPS were tested respectively after the heat treatment.The results showed that the temperature of strength loss of PP monofilaments was 120~130 ℃,the temperature of strength loss of PA6 monofilaments was about 150 ℃,the temperature of strength loss of PET monofilaments was 160~170℃ and the temperature of strength loss of PPS monofilaments was 220~230℃.The heat resistance of the PPS monofilaments was superior to that of other monofilaments.更多还原
