【摘要】 介绍了膨体变形丝(BCF)的有色切片纺丝、色母粒着色纺丝、熔体着色纺丝和本色切片纺丝后染色的着色方法;从原料、设备和工艺等方面剖析了有色BCF产生色差的原因,提出了预防措施;指出提高色母粒质量,采用高精度色母粒计量添加装置,选择适宜的工艺条件可降低有色BCF的色差。更多还原

【Abstract】 The pigment methods for bulked continuous fiber(BCF) were introduced including colored chip spinning,color masterbatch pigment spinning,melt pigment spinning and dyeing after grey chip spinning.The reasons for the color difference of colored BCF were explored from the aspects of the raw material,equipments and process technology.And the corresponding proventive measures were suggested.It was pointed out that the color difference of colored BCF could be decreased by improving the quality of color masterbatch,applying a high-precision color masterbatch metering device and selecting proper process conditions.更多还原
