Description

Technical Field

[0001] The utility model relates to the technical field of polyester cloth, in particular to a polyester cloth with flame retardancy. Background Art

[0002] Polyester is a synthetic fiber made of organic dibasic acid and diol by chemical polycondensation. It is a kind of polymer compound. It is the most important type of synthetic fiber. It has excellent wrinkle resistance and shape retention. The clothes made of it are not easy to wrinkle during wearing and can maintain the original shape of the clothes. Secondly, polyester has high strength and elastic recovery ability, which makes the woven fabric strong and durable, and can quickly restore to its original shape. In addition, polyester also has the characteristics of wear resistance and non-stick hair. In general, polyester is a very practical synthetic fiber. It is widely used in textile and clothing manufacturing. In order to avoid easy fire, a flame retardant layer is set on one side of the composite polyester cloth.

[0003] For example, the Chinese patent "A highly flame-retardant composite polyester cloth" with announcement number CN218749702U includes a composite polyester cloth body, a polyester layer is arranged in the middle part of the composite polyester cloth body, a first antibacterial layer is arranged above the polyester layer, a second antibacterial layer is arranged below the polyester layer, a first flame-retardant layer is arranged above the first antibacterial layer, a second flame-retardant layer is arranged below the second antibacterial layer, a wear-resistant layer is arranged above the first flame-retardant layer, and a skin-friendly layer is arranged below the second flame-retardant layer. The polyester layer is composed of a combination of polyester fiber lines and hydrophilic fiber lines, and the first flame-retardant layer and the second flame-retardant layer are both hot-pressed connected by a quartz fiber layer and an asbestos layer.

[0004] Although the above-mentioned prior art can achieve flame retardancy for polyester fabric, in actual use, on the one hand, the outer layer of the polyester fabric directly contacts the fire source, and the fire source directly heats the surface of the polyester through heat radiation, causing the surface temperature of the polyester fabric to rise until the polyester fabric reaches the melting point, thereby causing damage to the polyester fabric. On the other hand, polyester fabric products are in direct contact with the body, and some people may be allergic to polyester fibers. After contact with polyester fibers, they may cause allergic reactions, resulting in symptoms such as erythema, papules, itching, etc. In severe cases, palpitations, chest tightness, and dyspnea may also occur. Therefore, it does not meet the existing needs, and we propose a polyester fabric with flame retardancy. Utility Model Content

[0005] The purpose of the utility model is to provide a polyester cloth with flame retardancy to solve the problems proposed in the above-mentioned background technology that the outer layer of the polyester cloth directly contacts the fire source, the fire source directly heats the surface of the polyester through heat radiation, causing the surface temperature of the polyester cloth to rise until the polyester cloth reaches the melting point, thereby causing damage to the polyester cloth, and the polyester cloth products directly contact the body. Some people may be allergic to polyester fibers and may have allergic reactions after contacting polyester fibers, resulting in symptoms such as erythema, papules, itching, etc., and severe cases may also experience palpitations, chest tightness, and difficulty breathing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a polyester fabric with flame retardancy, comprising a polyester layer; and further comprising:

[0007] A flame retardant layer is arranged on the upper end of the polyester layer, and the flame retardant layer is bonded to the polyester layer. An aluminum foil is arranged at the middle position inside the flame retardant layer. Basalt fiber is arranged on the upper end of the aluminum foil. High-silica wool is arranged on the lower end of the aluminum foil. The aluminum foil is hot-pressed to the basalt fiber and the high-silica wool respectively.

[0008] Preferably, a heat insulating layer is provided at the lower end of the polyester layer, and the heat insulating layer is connected to the polyester layer by hot pressing.

[0009] Preferably, a cooling layer is provided at the lower end of the heat insulation layer, the interior of the cooling layer is filled with hydrogel, and the cooling layer is bonded to the heat insulation layer.

[0010] Preferably, a skin-friendly layer is provided at the lower end of the cooling layer, and the skin-friendly layer is bonded to the heat-insulating layer.

[0011] Preferably, a plurality of bamboo fibers and silk protein threads are arranged inside the skin-friendly layer, and the bamboo fibers and silk protein threads are woven in a mat-type mesh twill.

[0012] Preferably, a plurality of leather fibers and aluminum wires are arranged inside the heat insulation layer, and the aluminum wires and the leather fibers are woven alternately up and down.

[0013] Preferably, a wear-resistant layer is provided on the upper end of the flame-retardant layer, and the wear-resistant layer is connected to the flame-retardant layer by hot pressing.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model is provided with a flame retardant layer, which can prevent the direct contact between the fire source and the polyester cloth. When there is a fire source near the polyester cloth, the flame retardant layer is close to the fire source, and basalt fiber, aluminum foil, and high-silicon cotton are arranged in sequence inside the flame retardant layer. The top layer is basalt fiber, which can prevent flame burning, the middle layer is aluminum foil, which can prevent the heat of the fire source from spreading through thermal radiation, and the bottom layer of high-silicon cotton can isolate the heat of the fire source, thereby achieving the purpose of flame retardancy of the polyester cloth, avoiding the outer layer of the polyester cloth from directly contacting the fire source, and protecting the polyester cloth from being damaged by the fire source.

[0016] 2. The utility model is provided with a skin-friendly layer, which can prevent polyester products from directly contacting the body. When wearing polyester products, the body directly contacts the skin-friendly layer, which is made of bamboo fiber and silk protein thread woven through a mat-type mesh twill. This weaving method can make the skin-friendly layer more wear-resistant, extend the service life of the skin-friendly layer, enhance the tensile strength of the skin-friendly layer, and improve the air permeability of the skin-friendly layer. The surface of the skin-friendly layer woven through the mat-type mesh twill is not easy to absorb dirt and is easy to clean and maintain. At the same time, it also prevents the polyester cloth from directly contacting the body, causing allergic reactions in some people.

[0017] 3. The utility model can prevent a small amount of heat from passing through the polyester cloth to burn the human skin surface through the heat insulation layer and the cooling layer. When there is a fire source near the polyester cloth, the flame retardant layer of the outer layer of the polyester cloth can prevent the polyester cloth from being ignited and isolate most of the heat from the fire source. A small amount of heat will still be transferred to the heat insulation layer through the polyester cloth. After the heat insulation layer absorbs the heat, it can accelerate the heat conduction through the overlapping weaving of leather fibers and aluminum wires to avoid heat concentration in one place. At the same time, the cooling layer can cool the heat insulation layer through the internal hydrogel to prevent heat from burning the human skin surface. BRIEF DESCRIPTION OF THE DRAWINGS
