Master batches for production of polyester filaments, and preparation method and application thereof

The invention discloses master batches for production of polyester filaments, and a preparation method and application thereof. The problems that the traditional regenerated master batches cannot havethe characteristics of properties close to those of the original master batches and low cost are solved. According to the key point of the technical scheme, the master batches comprise the followingcomponents in parts by weight: 60 to 70 parts of waste plastic bottle sections, 10 to 40 parts of original master batches, 1 to 3 parts of defoaming master batches, 1 to 5 parts of compatibilizer and0.1 to 1 part of accelerant. The master batches prepared by the above formula have low cost, have excellent properties close to those of the original master batches, can be compatible with the waste plastic bottle sections well in the production of the polyester filaments and enables the polyester filaments to be uniform in character and color. 本发明公开了种用于涤纶长丝生产的母粒及其制备方法和应用，解决了传统再生母粒不能兼具具有接近原生母粒的性能与成本低廉的特性，其技术方案要点是包括如下重量份的组分：
