Problems solved by technology

The flame retardant and anti-dripping polyester produced by this method usually obtains the flame-retardant and anti-dripping properties at the expense of other properties of the fiber. With the addition of flame retardant and anti-dripping agents, the fiber strength and elongation tend to Weak; poor hand feeling; difficult spinning and weaving

Abstract

A method for preparing flame-retardant melt droplet-resistant polyester, consisting of the following steps: A) uniformly mixing four materials consisting of flame-retardant melt droplet-resistant basic magnesium sulfate whiskers, beta-type silicon nitride whiskers, tetra-needle like zinc oxide whiskers and magnesium salt whiskers; roasting in a vacuum furnace; stirring and dispersing in a sodium hexametaphosphate solution, treating by atmospheric-pressure plasma; filtering through a 200 mesh filter and drying; B) mixing the whiskers obtained from the step A) with flame retardant agents and a silane coupling agent at 75°C, where the flame retardant agents are melamine cyanurate (MCA) and microencapsulated red phosphorus; C) preparing a flame-retardant melt droplet-resistant whiskers ethylene glycol solution using the flame-retardant melt droplet-resistant whiskers obtained in the step B); D) preparing a flame-retardant melt droplet-resistant polyester from the flame-retardant melt droplet-resistant whiskers in a blending or copolyester manner, and preparing a sheath-core flame-retardant melt droplet-resistant polyester thread by means of compound spinning technology, where the surface layer of the thread is the flame-retardant melt droplet-resistant polyester.

Description

technical field [0001] The invention relates to a method for manufacturing flame-retardant and anti-melt-drip polyester, which includes polyester (PET), melamine cyanurate, microencapsulated red phosphorus flame retardant, tetrapod-like zinc oxide Whiskers, β-type silicon nitride whiskers, basic magnesium sulfate whiskers, magnesium salt whiskers; belong to the technical field of textile fiber manufacturing. Background technique [0002] Polyester is made from polyethylene terephthalate (PET). It is the largest variety of synthetic fibers at present. Because of the high rigidity of the fiber macromolecular chain and high elastic modulus, the fiber is not easily deformed, and the fabric does not wrinkle after washing, does not need to be ironed, is firm and scratchable, and is easy to wash and dry. It also has good heat resistance, cold resistance, sun resistance and abrasion resistance, and is an ideal textile raw material. Polyester is widely used in apparel, decoration,...
