摘要
探讨了影响聚酯切片色泽的因素 ,提出控制PTA质量、催化剂与添加剂种类及含量、生产负荷与真空度、聚酯的结晶度与羧基含量等主要因素 ,生产出色泽均一、晶亮的聚酯切片 。
Through exploring the possible factors which affect the colour of polyester chip, We finally produced homogeneously-coloured and bright polyester chip which has better colour and spinnability by means of controlling the quality of PTA, the kinds and content of catalyst and additives, the production load and vaccum level, the crystallinity of polyester and the content of carboxyl.
