Flame-retardant polyester yarn and sofa cloth made of same

Abstract

The invention discloses flame-retardant polyester yarn. The flame-retardant polyester yarn is characterized in that flame-retardant sheath yarn is included, and the flame-retardant sheath yarn is prepared by blending, by weight, 60-70 parts of a flame-retardant polyester fiber and 30-40 parts of a poly(m-phenylene isophthalamide) fiber; a flame-retardant additive in the flame-retardant polyester fiber accounts for 8%-10% of the weight percentage content of the 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, 1% of Mg(OH)2, 42%-55% of a binding agent, 1% of a thickening agent and 25%-34% of water. Accordingly, the advantages of flame retardancy, good structural strength and wear resistance are achieved.

Description

technical field [0001] The invention relates to the textile field, more specifically, it relates to a flame-retardant polyester yarn 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, which is easy to cause sa...

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
