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

Embodiment 1

[0038] A flame-retardant polyester yarn includes a metal core yarn 2 and a flame-retardant sheath yarn 1. The metal core yarn 2 is stainless steel fiber or silver fiber. In this embodiment, the metal core yarn 2 is selected to use stainless steel fiber from the viewpoint of cost and practical performance. In this embodiment, the polyester yarn is made of 80 parts by weight of the flame-retardant sheath yarn 1 as short filaments, and 20 parts by weight of the metal core yarn 2 as the filament core. The flame-retardant polyester yarn is also coated with Flame retardant coating agent, the coating weight of the flame retardant coating agent is 35% of the polyester yarn weight.

[0039] Among them, the flame-retardant sheath yarn 1 is made by blending 70 parts by weight of flame-retardant polyester fiber and 30 parts by weight of poly(metaphenylene isophthalamide) fiber. The flame-retardant additives in the flame-retardant polyester fiber account for The mass weight percentage content...

Embodiment 2

[0055] It is basically the same as Embodiment 1, with the only difference: In this embodiment, the polyester yarn is made of 90 parts by weight of flame-retardant sheath yarn 1 as short filaments and 10 parts by weight of metal core yarn 2 as filament core.

Embodiment 3

[0057] It is basically the same as the first embodiment, except that the coating weight of the flame-retardant coating agent in this embodiment is 40% of the polyester yarn weight.

Abstract

The invention discloses a flame-retardant polyester yarn. The key point of the technical solution is to include a flame-resistant sheath yarn, and the flame-resistant sheath yarn is composed of 60-70 parts by weight of flame-retardant polyester fiber and 30-40 parts by weight of polyisophthalic acid. Prepared by blending diformyl m-phenylenediamide fibers; the flame retardant additive in the flame retardant polyester fiber accounts for 8-10% of the mass weight percentage content of the flame retardant polyester fiber; the flame retardant additive is composed of the following components by weight Percent composition: melamine modified ammonium polyphosphate 11‑17%, pentaerythritol 2‑4%, melamine cyanurate 2‑4%, Mg (OH) 21%, binder 42‑55%, thickener 1%, water 25‑34%, achieving the effects of flame retardancy, good structural strength and wear resistance.

Description

Technical field [0001] The invention relates to the textile field, and more specifically, it relates to a flame-retardant polyester yarn and a sofa made of the polyester yarn. Background technique [0002] Due to its comprehensive properties such as good strength, wear resistance, high modulus, excellent heat resistance and dimensional stability, polyester has a very wide range of applications and industrial foundations in my country, and it is the most widely used synthetic fiber in China. . [0003] For example, in the production and manufacturing of the sofa, because the sofa has very high requirements on the strength and wear resistance of the yarn, the application of polyester in the sofa is very extensive. With the development and progress of society, people's safety requirements for daily necessities have also increased, and the oxygen index of polyester is 22-24, which not only has no flame retardant effect, but is also flammable, which is easy to cause safety hazards; , B...
