    • The synthetic threads are produced from a polymer mixture consisting of polyamide as base polymer and at least one additive polymer, the polymer mixture being pressed through nozzle openings as polymer melt with extrusion speeds (s) in the range from 18 to 160 m/min. The filaments thus formed are cooled, combined to threads, drawn off and spooled by forming at least one thread spool. The content of additive polymer in the polymer mixture is not less than M wt-% and not more than 2.5 wt-%, where M is derived from 0.0001nullvnull0.4, where v is the draw-off speed of the thread, and v lies in the range from 4500 to 8000 m/min. The additive polymer is amorphous and virtually insoluble in the polymer melt. In the spooled thread, the additive polymer is present in the base polymer in a fibril structure, the ratio s:v lies in the range from 1:50 to 1:250. Upon spooling, the thread spool preferably has a weight of the spooled thread of at least 4 kg.
    • 合成线由由聚酰胺作为基础聚合物和至少一种添加剂聚合物组成的聚合物混合物制成,聚合物混合物通过喷嘴开口作为聚合物熔体挤压,挤出速度为18至160m / min。 如此形成的细丝被冷却,组合成螺纹,通过形成至少一个螺纹卷轴被拉出和卷绕。 聚合物混合物中的添加剂聚合物的含量不低于M wt%且不大于2.5wt%,其中M是衍生自0.0001.v-0.4,其中v是螺纹的剥离速度, v在4500至8000米/分钟的范围内。 添加剂聚合物是无定形的并且几乎不溶于聚合物熔体。 在卷绕螺纹中,添加剂聚合物以原纤维结构存在于基础聚合物中,s:v的比例在1:50至1:250的范围内。 在卷绕时,线轴优选地具有至少4kg的卷绕螺纹的重量。

    • There is disclosed a process for removing volatile components in a polyarylene sulfide resin which is produced by subjecting a sulfur source and a dihalogenated aromatic compound to polymerization reaction in an aprotic organic solvent, comprising using an extruder which is equipped with front vent having an opening length in the range of 4D to 11D (D: screw diameter) and which has a distance between a terminal position of a screw in a kneading portion and the opening portion of the front vent being in the range of 4D to 15D. The process is capable of steadily and economically removing volatile components in the polyarylene sulfide resin without necessitating expensive machinery or equipment such as a dryer without plugging up the opening portion of a vent even in the case of degassing a PAS resin having a low molecular weight and further, thus enabling a long-term continuous stable running.
    • 公开了一种除去聚亚芳基硫醚树脂中的挥发性组分的方法,该方法是通过使硫源和二卤代芳族化合物在非质子性有机溶剂中进行聚合反应而制备的,其包括使用挤出机,该挤出机配备有具有开口长度 在4D至11D(D:螺杆直径)的范围内,并且其具有揉捏部分中的螺杆的终端位置与前排气孔的开口部分之间的距离在4D至15D的范围内。 该方法能够稳定且经济地除去聚芳硫醚树脂中的挥发性组分,而不需要昂贵的机械或设备如干燥机,而不会堵塞排气孔的开口部分,即使在脱气低分子量的PAS树脂的情况下, 从而能够长期持续稳定运行。
