利用原有的聚对苯二甲酸乙二酯(PET)纺丝及卷绕设备,采用前纺注入着色母粒的方法生产有色聚对苯二甲酸丙二酯(PTT)全拉伸丝(FDY)。结合PTT大分子的结构与性能,分析其特性,对有色PTT FDY生产过程中切片、色母粒的干燥,色母粒的加入量和纺丝、卷绕工艺等条件进行讨论,并对生产过程中易出现的色差问题提出了几点建议。
Using the original polyethylene terephthalate (PET) spinning and winding equipment, the method of pre-spinning into masterbatch to produce colored polytrimethylene terephthalate (PTT) fully drawn yarn (FDY ). Based on the structure and properties of PTT macromolecules, the characteristics of the PTT macromolecules were analyzed. The conditions of the chips, the drying of masterbatch, the amount of masterbatch and the spinning and winding processes of colored PTT FDY were discussed. The production process In the prone color problems put forward a few suggestions.
