Technical Field

[0001] The utility model relates to the technical field of polyester filaments, in particular to a flame-retardant and heat-insulating DTY polyester filament. Background Technique

[0002] Polyester drawn textured yarn, abbreviated as DTY, is made of polyester chips as raw materials, high-speed spun into polyester pre-oriented yarn, and then processed by drawing and false twisting. It has the characteristics of short process, high efficiency, and good quality.

[0003] Since DTY polyester filament is a synthetic fiber, but its inherent characteristics result in poor flame retardancy. Under long-term high temperature or open fire, the entire polyester fiber product will burn rapidly. Moreover, the antibacterial performance of DTY polyester filament is average. Therefore, we provide a flame-retardant and heat-insulating DTY polyester filament to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a flame-retardant and heat-insulating DTY polyester filament to solve this problem.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The insulating layer includes two groups of a first heat-insulating winding layer, a first elastic winding layer, a crack-resistant winding layer, a second heat-insulating winding layer, and an anti-ultraviolet winding layer each wound around the outside of the polyester inner core filament;

[0009] Further, the antibacterial fabric layer includes a first wear-resistant fiber layer, silver fiber, graphene fiber, and a second wear-resistant fiber layer. The first wear-resistant fiber layer and the second wear-resistant fiber layer are respectively located inside the flame-retardant layer and outside the insulating layer. Silver fiber and graphene fiber are respectively arranged on one side of the first wear-resistant fiber layer corresponding to each other.

[0010] Further, a soft layer is bonded between the graphene fiber and the silver fiber, and the soft layer is made of silica sol material.

[0011] Further, both the first wear-resistant fiber layer and the second wear-resistant fiber layer are made of polyamide fiber material.

[0012] Furthermore, the first heat-insulating winding layer is made of carbon fiber material, the second heat-insulating winding layer is made of pearl cotton fiber material, the first elastic winding layer is made of polyurethane elastic fiber material, the crack-resistant winding layer is made of rubber wire elastic fiber material, and the anti-ultraviolet winding layer is made of acrylic fiber material.

[0013] Furthermore, the first flame-retardant winding layer is manufactured by mixing polyester fiber, flame retardant particles and latex material.

[0014] Furthermore, the wear-resistant winding layer is made of aramid fiber material, the second flame-retardant winding layer is made of polyacrylonitrile flame-retardant modified fiber material, the second elastic winding layer is made of polyether ester elastic fiber material, and the antioxidant winding layer is manufactured by mixing polyester fiber and antioxidant.

The soft layer, the first wear-resistant fiber layer and the second wear-resistant fiber layer further protect the silver fiber and graphene fiber from damage, avoiding the damage of the silver fiber and graphene fiber under long-term rubbing and friction, which may lead to the destruction of the antibacterial effect of the silver fiber and graphene fiber;

[0018] 3. Through two groups of first flame-retardant winding layers made of polyester fiber, flame retardant particles and latex material, when encountering an open flame, after the surface of this DTY composite polyester filament burns, the flame retardant particles effectively prevent the open flame from adhering to the surface of this DTY composite polyester filament for a long time, effectively playing a flame-retardant effect.
