纺丝组件、纺丝组件的制造方法及纺丝组件的改造方法
摘要：
本发明提供一种纺丝组件、纺丝组件的制造方法及纺丝组件的改造方法。在使用了多边形截面金属短纤维过滤器取代粒状滤材的纺丝组件中尽量抑制组件内聚合物的滞留。纺丝组件(4)具备：具有聚合物填充空间(49)的流路形成体(40)，收容在聚合物填充空间(49)内的减容体(57)，具有烧结具有多边形截面的金属短纤维形成的第1过滤层(51)的过滤器(44)，以及形成有分别纺出通过了过滤器(44)的熔融聚合物的多个喷嘴(54)的喷丝头(41)。
摘要（英）：

The invention provides a spinning assembly, a spinning assembly manufacturing method, and a spinning assembly improving method. In a spinning assembly in which a granulous filtering material is replaced by a polygonal-section metallic short fiber filter, the retention of a polymer is suppressed as much as possible. The spinning assembly (4) is provided with a flow path forming body (4) with a polymer filling space (49), a volume reducing body (57) received in the polymer filling space (49), a filter (44) with a first filtering layer (51) formed by sintering the polygonal-section metallic short fiber, and spinning nozzles (41) of multiple nozzles (54) which spin fusion polymers passing through the filter (44).
