[0002] With the development of the economy and the progress of society, people's requirements for fabrics are getting higher and higher. As a fabric, the first thing that must be met is the safety and comfort of the fabric. On the premise of ensuring safety and comfort, people begin to pursue other functionalities of the fabric. Warmth and breathability are the priority issues that people consider when choosing fabrics. Ordinary fabrics are difficult to take into account breathability while pursuing warmth. As a result, when users wear warm fabrics for exercise, the sweat produced by the human body is difficult to be discharged from the fabric, causing discomfort to the user. The production of sweat will cause the fabric to be adsorbed on the surface of the human body, which further affects the comfort of the user. Utility Model Content

[0006] The thermal insulation and breathable core layer is formed by two groups of symmetrical first yarns and second yarns that are staggered and woven together. The second yarn forms several thermal insulation cavities in the horizontal direction by repeated looping. The first yarn passes through the thermal insulation cavities and is connected to the second yarn. Part of the outer periphery of the two adjacent groups of thermal insulation cavities is offset to form a gap. The two adjacent groups of gaps are combined to form a plurality of spaced ventilation parts, so that the thermal insulation and breathable core layer is connected to the outside world through the ventilation parts.

[0025] The names of the messages or information exchanged between multiple devices in the embodiments of the present application are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0026] Reference Figure 1 and Figure 2 , a warm and breathable fabric, comprising a warm and breathable core layer 1, a windproof layer 2 and a moisture absorbing layer 3 arranged on the lower surface of the warm and breathable core layer 1, wherein the warm and breathable core layer 1 is located between the windproof layer 2 and the moisture absorbing layer 3;

[0027] The thermal insulation and breathable core layer 1 is formed by two sets of symmetrical first yarns 11 and second yarns 12 that are staggered and woven. The first yarn 11 is twisted by a number of phase change fibers. Phase change fibers are obtained by blending microcapsules containing phase change materials with polymers. The phase change temperature range of the phase change material is 15-25°C. Within this temperature range, when the external temperature drops, the phase change material changes from liquid to solid, releasing heat, providing a heating effect, thereby enhancing the thermal insulation performance of the fabric. When the external temperature rises, the phase change material changes from solid to liquid, absorbing heat, and keeping the fabric comfortable. The second yarn 12 is formed by twisting a plurality of bamboo charcoal fibers. The bamboo charcoal fibers have strong toughness and wear resistance, unique resilience, strong longitudinal and transverse strength, and are stable and uniform. They have good adsorption properties and can absorb odors and harmful gases. At the same time, they themselves have certain warmth retention properties and can enhance the structural stability of the warm and breathable core layer 1. The staggered weaving arrangement will not destroy the phase change material in the first yarn 11, but can enhance the bonding force between the fibers and reduce fiber displacement during wearing, thereby ensuring the durability of the warmth retention and breathability of the warm and breathable core layer 1.

[0028] The second yarn 12 is repeatedly looped to form a plurality of thermal cavities 121 in the transverse direction. The first yarn 11 passes through the thermal cavities 121 and is connected to the second yarn 12, so that the thermal insulation performance of the first yarn 11 is long-lasting and stable, and is not easily weakened by an increase in the number of washings, thereby enhancing the thermal insulation performance of the fabric and greatly improving the use performance of the fabric. Partial outer circumferences of two adjacent groups of thermal cavities 121 are abutted to form gaps, and the two adjacent groups of gaps are combined to form a plurality of spaced ventilation portions 13, so that the thermal insulation and breathable core layer 1 is connected to the outside through the ventilation portions 13, thereby accelerating the air circulation inside the thermal insulation and breathable core layer 1, thereby regulating the humidity inside the fabric, so that the wearer always feels dry and comfortable, and enhancing the ventilation effect of the fabric.

[0029] The windproof layer 2 also includes a hydrophobic coating 21. The windproof layer 2 is made of tightly woven high-performance polyester fiber. This tightly woven structure can effectively block the invasion of cold air from the outside, and the hydrophobic coating 21 can prevent the penetration of liquid water such as rainwater and snow water, ensuring that the fabric can still maintain a certain degree of warmth in a humid environment. The hydrophobic coating 21 covers the surface of the windproof layer 2 away from the warm and breathable core layer 1.

[0030] Based on the above structure, since the thermal insulation and breathable core layer 1 is formed by two groups of symmetrical first yarns 11 and second yarns 12 that are staggered and woven, and the second yarns 12 are repeatedly looped to form a plurality of thermal insulation cavities 121 in the transverse direction, the first yarn 11 passes through the thermal insulation cavities 121 and is connected to the second yarn 12, so that the thermal insulation performance of the first yarn 11 is long-lasting and stable, thereby enhancing the thermal insulation performance of the fabric. Furthermore, since the hydrophobic coating 21 covers the upper surface of the windproof layer 2, the synergistic effect of the hydrophobic coating 21 and the windproof layer 2 effectively blocks the intrusion of cold air and prevents the penetration of liquid water such as rainwater and snow water, further enhancing the thermal insulation effect of the fabric and improving the comfort of human body when worn.

[0031] Furthermore, since the two adjacent groups of gaps are combined to form a plurality of spaced ventilation parts 13, when the user wears the fabric to exercise, the ventilation parts connect the inside of the thermal insulation and breathable core layer 1 with the outside world, thereby enhancing the heat exchange between the body surface and the outside world, and allowing air to circulate more easily in the thermal insulation and breathable core layer 1, thereby regulating the humidity inside the fabric, facilitating the volatilization of sweat, and enhancing the breathability of the fabric. In this way, while ensuring the thermal insulation performance of the fabric, the breathability of the fabric is effectively increased, making the fabric more comfortable, and solving the problem that when people pursue the functionality of the fabric, it is difficult for ordinary fabrics to take into account breathability while pursuing warmth, thereby further affecting the comfort of the user.

[0032] In one embodiment, referring to Figure 1 and Figure 3 The moisture-absorbing layer 3 is formed by the warp 31, the first weft 32 and the second weft 33 being woven in an offset manner. The warp 31 is twisted by a number of special-shaped cross-section fibers. The special-shaped cross-section fibers can use cotton fibers with a cross-shaped cross-section. The cotton fibers with a cross-shaped cross-section can increase the gaps between the fibers and improve the moisture absorption performance, so that the fabric can remain dry and breathable. The first weft 32 is twisted by a number of nano-porous polyurethane fibers. Nano-porous polyurethane fibers have extremely high air permeability and moisture permeability, and can quickly transfer sweat and water vapor from the skin surface. At the same time, when the ambient humidity is high, It can also absorb dry air from the outside world and adjust the humidity inside the fabric, so that the wearer always feels dry and comfortable, further enhancing the breathability of the fabric. The second weft 33 is twisted by several high-strength nylon fibers, which has good wear resistance, strength and elasticity. The first weft 32 is woven on the warp 31 at intervals along the length direction of the warp 31, and a second weft 33 is woven into the warp 31 in a three-in-one method to interweave with the warp 31, thereby enhancing the overall structural strength of the moisture-absorbing layer 3 and preventing fiber breakage during wearing that affects the breathability and moisture absorption properties of the fabric.

[0033] In the description of this application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting this application.

[0034] Those skilled in the art will appreciate that the above embodiments are intended only to clearly illustrate the present application and are not intended to limit the scope of the present application. Other changes or modifications may be made based on the above disclosure, and such changes or modifications are still within the scope of the present application.
