Background

Polyester fiber is also called polyester fiber, and is fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and dihydric alcohol. Polyester fiber, as an important raw material in the textile industry, alleviates the shortage of natural fiber to a great extent, and has wide applications because of its excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation performance, sunlight resistance, friction resistance, no mildew or moth-eating, ideal chemical reagent resistance, weak acid and weak alkali resistance, excellent spinning performance (spinnability), and wearing performance, etc., while polyester yarn products are mainly suitable for various fields such as covering yarn, socks, yarn, gloves, carpet, curtain, etc.

However, when polyester yarn products in the market are actually used, due to the fact that the moisture absorption is poor and the limiting oxygen index is low, the polyester yarn products are easy to burn when meeting a fire source, and therefore potential danger threats are caused to human bodies.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides the polyester yarn with the flame retardant function, and solves the problem that the polyester yarn products in the market are easy to burn due to poor hygroscopicity and low limiting oxygen index when in actual use, thereby causing potential danger threat to human bodies.

In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a dacron silk with fire-retardant function, includes the dacron silk body, the tea fiber layer has been laid to one side of dacron silk body, the glass fiber layer is stained with to one side of tea fiber layer, the polyamide fiber layer is stained with to one side of glass fiber layer, the outside on polyamide fiber layer is provided with fire-retardant layer.

Preferably, the outer side of the flame-retardant layer is provided with an elastic fiber layer.

Preferably, the polyester yarn body is a uniform and ordered yarn bundle formed by mutually twisting a plurality of groups of filaments, and the thickness of the polyester yarn body is 1500-2000 mu m.

Preferably, the flame-retardant layer is phenolic fiber, the fineness of the flame-retardant layer is 1.7-5.6dtex, and the strength of the flame-retardant layer is 1.14-1.58 cN/dtex.

Preferably, the glass fiber layer and the polyamide fiber layer are jointly connected by means of a pp adhesive.

Preferably, the horizontal cross-sectional areas of the glass fiber layer and the polyamide fiber layer are the same, and the thicknesses of the glass fiber layer and the polyamide fiber layer are 50-60 mu m.

Advantageous effects

The utility model provides a polyester yarn with a flame-retardant function. Compared with the prior art, the method has the following beneficial effects:

1. the utility model provides a polyester yarn with fire-retardant function, through being provided with the glass fiber layer, so when using, have the temperature resistant, fire-retardant, thermal-insulated and anti-corrosion performance, in addition because of being stained with the polyamide fiber layer in one side on the glass fiber layer again, so both mutually support, can supply its poor shortcoming of wear resistance, service life has further been improved, be provided with fire-retardant layer in the outside on polyamide fiber layer simultaneously, so compare with the polyester yarn on the market, its fire behaviour is better, thereby the problem of easily burning when having solved the meeting fire, user's safety has further been ensured.

2. The utility model provides a polyester yarn with fire-retardant function, has laid the tea fiber layer through the one side at the polyester yarn body, is provided with the elastic fiber layer in outside one side on fire-retardant layer, so when using, the tea fiber can play antibiotic and deodorant efficiency, has further ensured polyester yarn's health and safety, has reduced bacterial growing, and elastic fiber can improve holistic tolerance.
