High-elasticity flame-retardant polyester yarn

Abstract

The invention discloses a high-elasticity flame-retardant polyester yarn. According to the technical scheme, the high-elasticity flame-retardant polyester yarn is characterized by comprising a flame-retardant sheath yarn, wherein the flame-retardant sheath yarn is prepared from, by weight, 60-70 parts of flame-retardant polyester fiber and 30-40 parts of poly(isophthaloyl metaphenylene diamine) fiber through blending, a flame-retardant additive in the flame-retardant polyester fiber accounts for 8-10% of the weight of flame-retardant polyester fiber, the flame-retardant additive is prepared from, by weight, 11-17% of melamine modified ammonium polyphosphate, 2-4% of pentaerythritol, 2-4% of melamine cyanurate, 21% of Mg(OH), 42-55% of bonder, 1% of thickening agent and 25-34% of water. Thehigh-elasticity flame-retardant polyester yarn achieves the effects of flame retardance, good structural strength and abrasion resistance.

Description

technical field [0001] The invention relates to the field of textiles, more specifically, it relates to a flame-retardant polyester yarn with high elasticity and a sofa cloth made of the polyester yarn. Background technique [0002] Because of its comprehensive properties such as good strength, abrasion resistance, high modulus, excellent heat resistance and dimensional stability, polyester has a very wide range of applications and industrial foundations in my country, and is the most widely used synthetic fiber in China. . [0003] For example, in the production and manufacture of sofa cloths, because sofa cloths have very high requirements on the strength and wear resistance of yarns, polyester is widely used in sofa cloths. With the development and progress of society, people's safety requirements for daily necessities are also increasing, and the oxygen index of polyester is 22-24, which not only does not have flame retardant effect, but also belongs to flammable items, ...

AI Technical Summary

Problems solved by technology

With the development and progress of society, people's safety requirements for daily necessities are also increasing, and the oxygen index of polyester is 22-24, which not only does not have flame retardant effect, but also belongs to flammable items, which is easy to cause safety hazards; in addition , since the melting temperature of polyester is lower than its decomposition temperature, the droplet phenomenon will be serious during the combustion process

Although the molten droplets can take away part of the heat from the polymer substrate, which is beneficial to the flame retardancy of polyester, the molten droplets have brought more serious disasters: on the one hand, the molten droplets may cause the flame to spread to other places, causing a larger fire ; In addition, the droplet is easy to cause secondary injuries including scalds and burns. Therefore, the lack of flame retardancy and the defects of the droplet greatly limit the application of polyester in sofa releases
