Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides Figure 1-2 An insulating, cool and antibacterial fabric is shown, comprising an outer fabric 1 and an inner fabric 2, a multifunctional layer 3 is arranged between the outer fabric 1 and the inner fabric 2, a connecting layer 4 is arranged between the outer fabric 1 and the multifunctional layer 3 and between the multifunctional layer 3 and the inner fabric 2, and the outer fabric 1, the inner fabric 2 and the multifunctional layer 3 are all interwoven in a horizontal warp and vertical weft manner.

[0030] The outer fabric 1 is made of polyester yarn and nylon yarn interwoven with each other. The outer fabric 1 is made of polyurethane fiber and tetrafluoroethylene fiber in a mass ratio of 4:3. The yarn count of the outer fabric 1 is 90-95 metric deniers and the density is 280 yarns / 10cm-290 yarns / 10cm. Nylon yarn has high strength and toughness, which can increase the wear resistance and durability of the fabric. Polyester yarn also has good strength and elasticity. Interweaving the two can improve the overall strength of the fabric, making it more wear-resistant and stretch-resistant. Nylon yarn is usually softer than polyester yarn. After interweaving, the fabric can be made more textured and more comfortable to wear. At the same time, the blended fabric is relatively light in weight and is suitable for making lightweight clothing and outdoor products. Nylon has a certain waterproof property. By interweaving with polyester yarn, the waterproof ability of the fabric can be improved to a certain extent, making it have good water resistance. Polyester yarn has good wrinkle resistance. The interwoven fabric is easier to keep its shape and is not easy to wrinkle. This makes it easier to restore clothes to flat after washing, reduces the appearance of wrinkles, and facilitates daily care. Both fibers have good wear resistance, and interweaving can enhance the wear resistance of the fabric and make it more wear-resistant. In addition, they have good tolerance to general chemicals and are not easily corroded. Both nylon and polyester have good dyeing properties and can be dyed bright and rich colors. Moreover, the color stability of this blended fabric is good and it is not easy to fade or change color.

[0031] The inner fabric 2 is blended from wool fiber and Lycra fiber, the mass ratio of polyester yarn to nylon yarn is 7:2, the yarn count of the inner fabric 2 is 70-80 metric, and the density is 255 yarns / 10cm-270 yarns / 10cm. The wool fiber is soft and comfortable, and has natural elasticity and softness. Lycra fiber has good elasticity and recovery. The blended fabric can remain comfortable, not easily deformed, and fits the body. The addition of Lycra fiber makes the fabric have better wrinkle resistance, and it is not easy to wrinkle even after wearing, keeping the fabric neat and beautiful. Wool and Lycra fiber are both durable fibers. The blended fabric is more wear-resistant and can withstand long-term wearing and use. The addition of Lycra fiber makes the fabric excellent in elasticity, can adapt to the movement of the body, and keep the clothes fit and comfortable. Wool fiber has natural antibacterial properties and can inhibit the growth of bacteria. At the same time, wool fiber also has good hygroscopicity, can absorb sweat and discharge it, and keep the body dry.

[0032] The multifunctional layer 3 includes an insulating layer fabric 31, a breathable layer fabric 32 and an antibacterial layer fabric 33. The insulating layer fabric 31 is woven with glass fiber, the breathable layer fabric 32 is woven with polyurethane fiber, the breathable layer fabric 32 is a mesh-shaped fabric, and the antibacterial layer fabric 33 is made of nano-silver fiber interwoven between the insulating layer fabric 31 and the breathable layer fabric 32.

[0033] Glass fiber is an inorganic non-metallic material with excellent performance and good insulation. It can be used to weave into insulating fabrics to effectively prevent the passage of current, ensuring personal safety and normal operation of equipment.

[0034] Polyurethane fiber itself has certain breathability, and the grid structure increases the breathable area of ​​the fabric, allowing air to pass through the fabric more freely, thereby providing better breathability. The breathable layer fabric can help sweat evaporate, keep the skin dry, and provide a comfortable wearing experience. It is particularly suitable for making underwear or clothing used in hot environments. The surface of the fabric with a grid structure is relatively rough, which can effectively resist dust and dirt and reduce the contact of pollutants with the skin. Polyurethane fiber has good elasticity and ductility and can adapt to the movement and stretching of the body. At the same time, the grid structure also helps to provide additional support and comfort. Polyurethane fiber has good wear resistance and tensile resistance, making the fabric durable and not easy to deform, suitable for long-term use. Polyurethane fiber fabrics usually have good water washing performance, are easy to clean and maintain, and can easily keep clothes clean and tidy;

[0035] Nanosilver fiber has strong antibacterial ability and can effectively inhibit the growth of bacteria, fungi and other microorganisms, thereby maintaining the hygiene of fabrics and reducing the risk of cross-infection. Nanosilver fiber has antibacterial effects on a variety of bacteria and fungi, including difficult-to-kill bacteria such as Staphylococcus aureus, Escherichia coli and Candida albicans. The antibacterial effect of nanosilver fiber is long-lasting. Even after repeated washing and use, it can still maintain its antibacterial properties, reducing dependence on frequent washing. Nanosilver fiber is safe and harmless to human skin, will not cause allergic reactions, and has no negative impact on the environment. Nanosilver fiber is compatible with various textiles and can be used to make various clothing and household items without affecting the original performance and feel of the textiles. The addition of nanosilver fiber can increase the added value of the product and make the product more competitive and attractive in the market.

[0036] The connecting layer 4 is mainly woven from Gore-Tex fiber, the yarn count of the connecting layer 4 is 40 to 60 metric deniers, and the density is 280 to 290 yarns / 10cm. The Gore-Tex fiber has excellent strength and durability. As a connecting layer, it can maintain the stability of the clothing structure and avoid wearing discomfort caused by fabric movement. The Gore-Tex fiber itself has waterproof and breathable properties. The connecting layer can ensure that the joints between different fabrics also have these functions to avoid moisture penetration, reduce friction at the joints of different fabrics, and improve wearing comfort. The Gore-Tex fiber has a certain corrosion resistance. The connecting layer can resist sweat and chemicals in the environment and extend the service life of the clothing. The Gore-Tex fiber can be flexibly applied to a variety of different fabric joining methods, such as stitching, bonding, etc., to meet different design and functional requirements. The Gore-Tex fiber can maintain its performance at different temperatures, whether it is severe cold or hot summer, it can maintain the waterproof and breathable function of the clothing. The Gore-Tex fiber has a low density. As a connecting layer, it can reduce the overall weight and volume of the clothing, making it easy to carry and move.
