Abstract

The invention relates to the technical field of polyester yarn preparation processes, and provides a polyester yarn with flame retardance and a preparation process thereof. Flame retardants 2-carboxyethyl phenyl hypophosphorous acid and dimethyl methylphosphate are added in the process of esterifying PTA into PET; the flame retardant 2-carboxyethyl phenyl hypophosphorous acid and a dimethyl methylphosphate monomer can be embedded into the PTA macromolecular chain through the esterification reaction to form the PET, so that the 2-carboxyethyl phenyl hypophosphorous acid and the dimethyl methylphosphate can be closely arranged in the gaps of the PTA macromolecules so as to form the flame-retardant PET through copolymerization; at a high temperature, 2-carboxyethyl phenyl hypophosphorous acid and the dimethyl methylphosphate can exert the flame retardant property for flame retardance; and then flame-retardant PET is prepared into the flame-retardant polyester fiber, the flame-retardant polyester fiber is spun into the polyester yarn with the flame-retardant performance; and the polyester yarn prepared through the preparation process has no side reaction, does not affect the fiber performance and has permanent flame retardance.

Description

technical field [0001] The invention relates to the technical field of polyester yarn preparation technology, in particular to a flame-retardant polyester yarn and a preparation process thereof. Background technique [0002] Polyester yarn refers to the yarn spun from polyester. Polyester is a kind of fiber made of polymer by spinning. At present, it mostly refers to the fiber produced from ethylene phthalate as raw material. According to its raw material English name "polyethyleneterephthalate" abbreviation, referred to as "PET" fiber. Commonly known as polyester in our country. The so-called "yarn" actually refers to the general term of "yarn" and "thread". Rotating and twisting to form a slender object with a certain strength and linear density; and the "thread" is a strand formed by twisting two or more single yarns. Yarn is a thin strand made of cotton, wool, hemp, chemical fiber, etc., which is elongated and twisted, and then multi-strand thin strands twisted with t...
