[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1

[0015] Combine Figure 1 This embodiment is described in detail. A cut-resistant and stab-resistant cool underwear comprises: a front panel 1 and a back panel 2; the front panel 1 is an air layer fabric, and the air layer fabric comprises a surface layer 3, a middle layer 4 and an inner layer 5; the surface layer 3 and the inner layer 5 are weft-knitted by ultra-high molecular weight polyethylene fiber filaments; the back panel 2 is knitted by core-spun yarn; the core yarn of the core-spun yarn is low-temperature spandex filament, and the wrapping yarn is ultra-high molecular weight polyethylene fiber filament, and the wrapping yarn is spirally wound on the outside of the core yarn.

[0016] Weft-knitted fabrics offer excellent impact energy absorption and wear comfort. Among all types of fabric, weft-knitted fabrics exhibit superior breathability, softness, and impact resistance. The yarns of the middle layer 4 are spirally wound along the wales of the surface layer 3 and the corresponding wales of the inner layer 5, connecting the surface layer 3 and the inner layer 5. This three-layer air layer fabric, used as the front panel 1, improves the fabric's ability to absorb puncture energy, meeting puncture protection requirements.

[0017] Ultra-high molecular weight polyethylene fiber is the strongest chemical fiber. Its main chain is a highly symmetrical methylene structure. The theoretical breaking strength is as high as 328cN / dtex. The actual breaking strength of mainstream products is 30-50cN / dtex. The initial modulus is greater than 900cN / dtex. It is a high-strength and high-modulus fiber with a density of only 0.97g / cm 3 , lower than most synthetic fibers, and has good chemical stability, impact resistance and cut resistance.

[0018] Polyethylene filaments are made from melt-spun polyolefins. They possess a repetitive linear molecular structure and are typical intrinsically thermally conductive fibers. Their thermal conductivity is enhanced by modifying the macromolecular aggregate structure during the fiber forming process to achieve a unique molecular chain configuration. Compared to ordinary polyethylene filaments, highly stretched and oriented ultra-high molecular weight polyethylene (UHMWPE) exhibits hundreds of times higher thermal conductivity. This superior thermal conductivity surpasses that of modified thermally conductive polymers, and UHMWPE fibers exhibit excellent instantaneous cooling properties.

[0019] Furthermore, the front sheet 1 has a gram weight of 580 g / m2, and the back sheet 2 has a gram weight of 350 g / m2.

[0020] Furthermore, the fineness of the ultra-high molecular weight polyethylene fiber filaments used in the surface layer 3 and the inner layer 5 is 400D.

[0021] Furthermore, the fineness of the low-temperature spandex filament used in the core yarn is 40D, and the fineness of the ultra-high molecular weight polyethylene fiber filament used in the wrapping yarn is 200D. The post-processing temperature of ultra-high molecular weight polyethylene generally does not exceed 120°C, so the heat setting temperature of the low-temperature spandex filament is 85°C. The back piece 2 is knitted from core-spun yarn. The low-temperature spandex filament serves as the core yarn of the core-spun yarn and has good elasticity. The core-spun yarn elastic fabric made of ultra-high molecular weight polyethylene fiber filament as the wrapping yarn has good adaptability to the body. As the back piece 2 of the anti-cut and anti-stab cooling underwear, it has a certain elasticity without a sense of oppression. At the same time, the soft and elastic fabric properties of the knitted fabric and the structural characteristics of the coil string determine the good absorption of the knitted fabric to puncture energy.

[0022] Furthermore, the middle layer 4 is woven from 200D, 300D or 400D ultra-high molecular weight polyethylene fiber filaments. Specifically, the middle layer 4 is woven from 200D ultra-high molecular weight polyethylene fiber filaments.

[0023] Example 2

[0024] Based on the first embodiment, the back panel 2 is a weft-knitted double rib fabric, which is woven by combining two rib structures, i.e., arranging a wale of coils of another rib structure between a wale of coils of the same rib structure. The weft-knitted double rib fabric is composed of coil units, and the coils have the characteristic of length transfer. When the double rib structure fabric is cut by a knife, the yarn first changes from a round shape to an oblate shape after being compressed. Then, the adjacent wales will shift in the direction of the force. The transverse connecting lines of the coils transmit the force to both sides, and the longitudinal force of the coils shifts. The deformation of the coils and the length transfer of the coils absorb a large amount of energy, thereby alleviating the yarn from being cut and breaking. When the double rib structure fabric is stabbed by a knife, the knife tip first penetrates the surface coils. Because the knitted fabric coils have the characteristic of coil length transfer, when a coil is stretched by a small force, the length of the adjacent coils will quickly shift toward the coil. At this time, the yarn is cut by the blade under a very small axial holding tension, and the cutting force is very small. As the cutter falls, the area where the tip of the cutter penetrates the coil increases rapidly. After the coil moves to a certain extent, it stops moving and the tip of the cutter is locked by the coil. The blade begins to have a significant cutting effect on the locked coil. At this time, the locked coil is no longer a single coil, but is surrounded by multiple coils. The force is dispersed and transferred accordingly. Therefore, the weft knitted fabric has a good buffering and locking effect on the blade. Combined with the good impact resistance and cut resistance of the ultra-high molecular weight polyethylene fiber filament, the back sheet 2 has good anti-cut and anti-stab properties.

[0025] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
