涤纶短纤维疵点成因探讨

Discussion on the causes of PET staple defects

从PET熔体原料、生产工艺等方面分析了涤纶短纤维的疵点成因,通过严格的控制熔体品质、纺丝工艺、后加工工艺,达到疵点含量符合控制标准,从而提高短纤维的品质。

The causes of PET staple defects were analysed from PET melt raw material and production process. By strict controlling of melt quality, spinning process and after-processing technology, the defects content can meet the control standard. The quality of PET staple was increased.
