    Abstract: Staple fibre is produced by extruding a solution of a polymer through a spinneret to form continuous filaments, gathering the continuous filaments to form a tow and continuously cutting the filaments in a cutter to form staple fibre. At least one jet of gas is blown at the tow before it enters the cutter to reduce smearing of polymer on the cutter. The process is particularly advantageous for treating water-soluble or water-absorbent filaments.

    Abstract translation: 通过将聚合物溶液通过喷丝头挤出以形成连续长丝,聚集连续长丝以形成丝束并在切割器中连续切割长丝以形成短纤维来生产短纤维纤维。 在进入切割机之前,至少一束气体在丝束处被吹送,以减少切割器上聚合物的污迹。 该方法特别有利于处理水溶性或吸水长丝。
