[0002] Labor protection fabrics usually refer to coarse twill cotton fabrics with tight texture, strong and durable. Most of the fabrics are thick, strong, friction-resistant, elastic, not close-fitting, moisture-absorbent, sweat-permeable, wear-resistant and dirt-resistant. They are also natural, simple, rough and casual in style and are often used as work clothes.
[0003] At present, some special workers, such as workers engaged in welding, metal hot stamping and metal pouring operations, basically wear work clothes with multi-layer composite fabrics. Although it can improve the safety performance of the workers, the composite fabric is thick and has poor breathability. The rate at which the wearer's skin sweat is discharged to the outside world is relatively slow, and the wearer's skin is easily damp and hot and has poor comfort. If they stay in a humid and hot environment for a long time, it is easy to breed bacteria and affect the health of the wearer's skin. In addition, the temperature difference between the wearer's working environment and the outside world is large. When switching between working and non-working states, the fabric has a poor ability to slow down the change in human body surface temperature, and the wearer is prone to catching a cold due to the large change in body surface temperature.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1-2The utility model provides a technical solution: an impact-proof, antibacterial and flame-retardant composite fabric, including a flame-retardant layer 1, the flame-retardant layer 1 is a composite material of polyacrylonitrile fiber fabric and aluminum foil, does not contain asbestos, has the advantages of light specific gravity, high temperature resistance, heat insulation, fire resistance, high strength, wear resistance, softness and non-toxicity to the human body, the inner surface of the flame-retardant layer 1 is provided with a composite layer 2, the composite layer 2 includes a buffer layer 201, an antibacterial layer 202, a temperature control layer 203, a skin-fitting layer 204, a moisture conductive line 205, a heat conductive line 206 and a breathable hole 207, the buffer layer 201 is located on the inner surface of the flame-retardant layer 1, the buffer layer 201 is a temperature-sensitive memory cotton, the internal cell tissue allows air to flow therein, and a part of the air is squeezed out when under pressure, After the pressure is removed, the air is re-injected and slowly rebounds to its original shape. The buffer layer 201 is soft and tough. When impacted by external force, it can be compressed and deformed to buffer the impact force and play a certain anti-impact effect. The inner surface of the buffer layer 201 is provided with an antibacterial layer 202. The antibacterial layer 202 is chitosan fiber cloth, which is made of chitosan after deacetylating the acetyl group by concentrated alkali treatment. It is also called deacetylated chitosan or chitosan fiber, which has good broad-spectrum antibacterial properties, hygroscopicity and degradability. The inner surface of the antibacterial layer 202 is provided with a temperature control layer 203. The temperature control layer 203 is an air-conditioning fiber cloth. PCM (nano microcapsule) is implanted into the fiber during the production process of the fiber. When the temperature reaches a certain value, The capsule undergoes a physical transformation (solid-liquid) to achieve the functions of absorbing and releasing heat, thereby slowing down the change of human body surface temperature and maintaining comfort. The inner surface of the temperature control layer 203 is provided with a skin-fitting layer 204, which is woven from Bemberg yarn and has the advantages of anti-static, small shrinkage, natural color, gloss, soft texture, fine texture, good toughness, environmental protection, moisture absorption and perspiration, etc. It is called a breathable, pure natural and environmentally friendly lining. The skin-fitting layer 204 is sewn with the flame-retardant layer 1 through a moisture-conducting line 205, which is a four-channel heterosexual polyester fiber line, which is a special-section fiber with a cross-shaped cross-section, so four grooves are formed on the surface of the fiber. At the same time, the surface area of the fiber is also increased, and the grooves are used to The siphon of the groove can absorb moisture from the body surface and evaporate it as quickly as possible. The outer side of the moisture-conducting line 205 is twisted and woven with a heat-conducting line 206. The heat-conducting line 206 is a mica cooling fiber line with excellent thermal conductivity. A plurality of air holes 207 are evenly arranged on the outer surface of the flame-retardant layer 1. The air holes 207 can improve the ventilation effect of the flame-retardant layer 1. The air holes 207 are oblique hole structures with an angle of 40-50° with the surface of the flame-retardant layer 1. The air holes 207 with the oblique hole structure can effectively reduce the probability of external impurities entering the flame-retardant layer 1 through the air holes 207. The density of the plurality of moisture-conducting lines 205 is 10-20 per square inch, and the suture density is relatively high, which can ensure the stable docking between the skin-contacting layer 204 and the flame-retardant layer 1.
[0016] When the flame retardant layer 1 with the composite layer 2 is made into special labor protection clothing and is worn, parts of the skin-contacting layer 204, the moisture-conducting line 205 and the heat-conducting line 206 will directly contact the wearer's skin or the wearer's underwear. The skin-contacting layer 204 is moisture-absorbent and perspiration-wicking, and has a soft texture, and the skin-fitting feeling is relatively comfortable. The flame retardant layer 1 is located on the outermost side of the clothing and contacts the outside world. It has a flame retardant effect and a certain heat insulation effect, which can alleviate the impact of the high temperature environment of the outside working environment on the inner skin of the wearer. During the work, the wearer's skin discharges sweat and moisture, which can be quickly evaporated to the outside through the moisture-conducting line 205. Combined with the excellent heat conduction effect of the heat-conducting line 206, the wearer's skin can improve the damp and stuffy feeling. The antibacterial layer 202 has antibacterial Performance, so that the wearer's skin can maintain a healthy state. In addition, the temperature control layer 203 can slow down the change of human body surface temperature, so that when the wearer switches between working and non-working environments, the chance of catching a cold due to a large change in body surface temperature is reduced. The buffer layer 201 is soft and tough. When impacted by external force, it can be compressed and deformed to buffer the impact force and play a certain anti-impact effect. The open cell tissue inside allows air to flow in it. When compressed, part of the air is squeezed out. After the pressure is removed, it slowly bounces back to its original shape due to the re-injection of air. Then, during the compression deformation process of the fabric, the buffer layer 201 can improve the overall air permeability of the fabric during compression and rebound. It has strong functionality and is easy to promote and use.
