Abstract

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.

Description

technical field [0001] The invention relates to a masterbatch, in particular to a masterbatch used in the production of polyester filaments, a preparation method and application thereof. Background technique [0002] Polyester filament, also known as polyester filament, refers to a synthetic fiber produced from polyethylene terephthalate. It is made of polyester chips and masterbatch after high-temperature melting and spinning. It has the advantages of high color fastness, environmental protection, and no need for dyeing. It is known as "a revolution in the textile industry". [0003] In the production of colored polyester filaments, after obtaining the color masterbatch formula for colored spinning according to computer color matching, weigh the required three primary color masterbatches according to the formula and mix them well, then dry the composite color masterbatches and accurately measure and continuously inject them The screw extruder mixes the composite color mast...
