Abstract

The invention discloses a preparation method of flame-retardant droplet-resistant terylene. The preparation method comprises the following steps of: A) evenly mixing four materials including a flame-retardant droplet resistant basic magnesium sulfate whisker, a beta-type silicon nitride whisker, a tetrapod-like zinc oxide whisker and a magnesium salt whisker, baking the mixture in a vacuum furnace; stirring and dispersing the mixture in a sodium hexametaphosphate solution, carrying out atmospheric pressure plasma treatment, and then filtering and baking the solution by a filter with 200 meshes; B) mixing the whiskers obtained from the step A) with flame-retardant melamine cyanurate, a microencapsulated red phosphorus retardant, and a silane coupling agent under the condition of 75 DEG C; C) preparing a flame-retardant droplet resistant whisker ethylene glycol solution by a flame-retardant droplet resistant whisker obtained in the step B); and D) preparing a flame-retardant droplet resistant polyester from the flame-retardant droplet resistant whisker in a blending or copolyester manner, and preparing the sheath-core flame-retardant droplet resistant terylene of taking the flame-retardant droplet resistant polyester as a skin layer by using a compound spinning technology.

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,...
