高速成网非织造布用丙纶细旦纤维的研制

The Development of Polypropylene Fine-denier Fiber for the Use of High-speed Web Formation Non-woven Fabrics

高速、高性能纤维具有高渗水、高柔软、高速梳理、高速铺网、高效热粘合等优良特性。介绍研制高速、高性能非织造布型丙纶细旦短纤维的原料要求、设备特征、工艺流程。研制结果表明 :选用的PP原料MI要低些 ,纺丝油剂上油率一般在 0 4%～ 0 6

High speed,high performance fiber has the excellent properties of high permeation,super soft,high speed carding,high speed web laying and high performance thermal bonding etc The paper introduces the raw material requirement for the development of high speed,high performance non woven type polypropylene fine denier fiber,equipment characteristics and technological process The result of the development indicates that MI of the selected PP raw material should be lower,the oil pick up of finishing oil should be generally between 0 4%-0 6%
