提高PET纺黏非织造布牵伸丝品质的途径

The ways to improve the PET spunbonded nonwovens drawn yarn quality

从PET切片品质,熔体品质,纺丝速度和温度,泵供量,采用异形喷丝孔纺丝,控制牵伸丝的稳定性,连续性,提高牵伸气流速度和密度等方面,介绍了提高PET纺黏非织造布牵伸丝品质的途径。

The ways to improve the PET spumbonded nonwovens drawn yam quality were introduced from the aspects such as PET chip quality, melt quality, spinning speed and temperature, pump delivery, using special-shaped spinneret hole to spin, controling the yarn stability and continuty,increasing the drawing flow speed and density.
