Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of fabrics, and in particular to a composite fabric with heat preservation and breathability functions. Background Art
[0002] With the development of material science and textile technology, consumers' requirements for clothing are increasing day by day. As a key component of clothing and other products, the performance of fabrics directly affects the quality of the final products and the user experience of consumers. When existing wearers exercise while wearing clothing made of breathable fabrics, due to the accumulation of sweat and moisture generated by exercise, although it can provide a certain degree of breathability, it is easy to cause the humidity inside the clothing to be too high, and the fabric itself lacks heat preservation effect, thus bringing discomfort to the wearer. Utility Model Content
[0003] The purpose of this utility model is to provide a composite fabric with heat preservation and breathability functions to solve the above problems.
[0004] The technical solution of the present disclosure is implemented as follows:
[0005] The present disclosure provides a composite fabric with heat preservation and breathability functions, including an outer layer, a heat preservation layer, and an elastic layer. The outer layer and the heat preservation layer are connected through the elastic layer. There is a cavity between the heat preservation layer and the elastic layer, and a heat preservation inner liner is arranged in the cavity;
[0006] The heat preservation layer includes warp yarns, weft yarns, and heat preservation yarns. A plain stitch structure is formed by interweaving between the warp yarns and the weft yarns. The heat preservation yarns are lined into the plain stitch structure and are located between the warp yarns and the weft yarns;
[0007] Villi are evenly distributed on the surface of the heat preservation layer away from the heat preservation inner liner;
[0008] Ventilation holes are arranged on the side of the outer layer away from the elastic layer. The ventilation holes are provided in several numbers and are evenly distributed on the surface of the outer layer. External air is communicated with the elastic layer through the ventilation holes.
[0009] In an embodiment, a heating gasket is further arranged on the side of the heat preservation layer away from the heat preservation inner liner, and the heating gaskets are evenly distributed on the surface of the heat preservation layer;
[0010] The heating gasket is located inside the villi;
[0011] The heating gasket is made of heat-absorbing and heat-generating fibers.
[0012] In an embodiment, a conductive wire is further included. One end of the conductive wire is sewn inside the heat preservation layer, and the other end passes through the heat preservation inner liner and is sewn and connected to the inside of the elastic layer.
[0013] In one embodiment, a waterproof membrane is provided between the outer layer and the elastic layer. The waterproof membrane is evenly distributed with flow micropores that penetrate the waterproof membrane, and the flow micropores communicate with the breathable pores;
[0014] The aperture of the flow micropores is smaller than that of the breathable pores.
[0015] In one embodiment, the thermal insulation inner liner is filled with cotton wadding or down.
[0016] In one embodiment, the thermal insulation yarn is woven from a mixture of polyester fiber and acrylic fiber.
[0017] In one embodiment, the elastic layer is formed by mixing and weaving nylon fiber and spandex fiber.
[0018] In one embodiment, the outer layer is formed by mixing and weaving polyester and acrylic fiber.
[0019] The advantages or beneficial effects in the above technical solutions at least include:
[0020] A composite fabric with thermal insulation and breathability functions disclosed in the present disclosure has fluff on one side of the thermal insulation layer in contact with the skin, so that an air layer can be formed on the surface to effectively reduce heat dissipation and achieve a thermal insulation effect. And because the thermal insulation layer is provided with thermal insulation yarn made of heat-absorbing and generating fibers, when the heat and moisture generated by the skin are transferred into the thermal insulation layer, the thermal insulation yarn adsorbs and generates heat, thereby maintaining the temperature inside the thermal insulation layer. Moreover, since the outer layer is provided with breathable pores communicating with the external air, and there is a thermal insulation inner liner between the thermal insulation layer and the outer layer to block, the flow rate of the fabric gas is reduced, and the internal gas exchange can be realized while maintaining a certain temperature, solving the problem that the existing fabric lacks thermal insulation effect while having breathability.

[0037] ReferenceFigures 1 - 4 , a composite fabric with heat preservation and breathability functions, comprising an outer layer 1, a heat preservation layer 2 and an elastic layer 3. The outer layer 1 and the heat preservation layer 2 are connected through the elastic layer 3. The outer layer 1 is formed by mixing and weaving polyester and acrylic. The elastic layer 3 is formed by mixing and weaving nylon fiber and spandex fiber. There is a cavity between the heat preservation layer 2 and the elastic layer 3, and a heat preservation inner liner 4 is arranged in the cavity. The heat preservation inner liner 4 is filled with cotton wadding or down. The outer layer 1 is on the side where the fabric contacts the outside, and the heat preservation layer 2 is on the side where the fabric contacts the skin. By sewing the heat preservation layer 2 and the outer layer 1 with the elastic layer 3, the elastic layer 3 can control the tension of the fabric and avoid the deformation of the fabric;
[0038] The heat preservation layer 2 includes warp yarns 21, weft yarns 22 and heat preservation yarns 23. A plain stitch structure is formed by interweaving the warp yarns 21 and the weft yarns 22. The plain stitch structure is a common knitting structure, also known as plain stitch or plain weave. It is formed by alternating continuous front coils and back coils. The softness and elasticity of the plain stitch structure make the clothes comfortable to wear. The heat preservation yarns 23 are lined into the plain stitch structure and are located between the warp yarns 21 and the weft yarns 22. The heat preservation yarns 23 are formed by mixing and weaving polyester fiber and acrylic. The heat preservation layer 2 is woven with a padding structure;
[0039] On the surface of the heat preservation layer 2 away from the heat preservation inner liner 4, fluff 24 is evenly distributed. The setting of the fluff 24 can further improve the heat preservation effect of the heat preservation layer 2, and the contact between the fluff 24 and the skin can further improve the comfort during wearing;
[0040] Ventilation holes 11 are arranged on the side of the outer layer 1 away from the elastic layer 3. Several ventilation holes 11 are arranged and evenly distributed on the surface of the outer layer 1. External air is communicated with the elastic layer 3 through the ventilation holes 11, and the breathability effect of the fabric is realized through the setting of the ventilation holes 11.
[0041] Based on the above structure, since the heat preservation layer 2 is on the side in direct contact with the skin, the heat preservation yarns 23 in the heat preservation layer 2 can increase the overall temperature in the heat preservation layer 2. And by filling a heat preservation inner liner 4 between the heat preservation layer 2 and the elastic layer 3, the heat preservation inner liner 4 can block the external air and the heat dissipated inside, reduce the heat flow, and thus play a heat preservation effect. And there is fluff 24 on the heat preservation layer 2. The setting of the fluff 24 can further reduce the temperature fluctuation and improve the comfort during wearing. Also, since ventilation holes 11 are arranged on the outer layer 1, when external air moves to the heat preservation layer 2 through the ventilation holes 11, it needs to pass through the elastic layer 3 and the heat preservation inner liner 4. Therefore, the gas temperature exchange speed can be reduced, so that the fabric can achieve the breathability effect while keeping warm, and solve the problem of poor heat preservation effect of the existing fabric.
[0042] In one of the implementation modes, referring to Figure 1, Figure 2 and Figure 4 , on the side of the heat preservation layer 2 away from the heat preservation inner liner 4, a heating gasket 25 is further arranged. The heating gaskets 25 are evenly distributed on the surface of the heat preservation layer 2. The heating gaskets 25 are located inside the fluff 24. The heating gaskets 25 are made of heat-absorbing fibers. The heat-absorbing fibers refer to fibers that can absorb and store heat, and can be woven from acrylonitrile fibers or polyester fibers. Since the heating gaskets 25 are on the side of the heat preservation layer 2 in direct contact with the skin, when the skin generates heat and transfers it to the heating gaskets 25, heat is generated and released inside the heating gaskets 25, thereby improving the overall heat preservation effect of the heat preservation layer 2.
[0043] In one implementation, referring to Figures 1 - 4 , it further includes a conductive wire 5. One end of the conductive wire 5 is sewn inside the heat preservation layer 2, and the other end passes through the heat preservation inner liner 4 and is sewn and connected to the inside of the elastic layer 3. In order to improve the heat preservation effect of the made clothing, one side of the heat preservation layer 2 is attached to the skin. The conductive wire 5 is a textile fiber with a metal wire or carbon fiber. Since the climate is dry in winter, when wearing the clothing and moving, the skin and the clothing will rub against each other, resulting in static electricity generated on the clothing. Through the setting of the conductive wire 5, the static electricity can be guided, and the static charges are transmitted to the inside of the fabric through the conductive wire 5, achieving the effects of preventing static shock and eliminating static electricity.
[0044] In one implementation, referring to Figure 1 and Figure 2 , a waterproof membrane 6 is arranged between the outer layer 1 and the elastic layer 3. The waterproof membrane 6 is made of TPU material. Flow micro-holes are evenly distributed on the waterproof membrane 6. The flow micro-holes penetrate through the waterproof membrane 6. The flow micro-holes are interconnected with the ventilation holes 11. The aperture of the flow micro-holes is smaller than that of the ventilation holes 11. Through the interconnection between the flow micro-holes and the ventilation holes 11, the heat generated by the skin can be transferred to the flow micro-holes and discharged through the ventilation holes 11. And the setting of the flow micro-holes can block the external liquid by the waterproof membrane 6 before it flows through the ventilation holes 11 and enters the elastic layer 3. And the aperture of the flow micro-holes is smaller than the aperture of water molecules, so it can prevent the external liquid from directly penetrating into the inside of the fabric from the outer layer 1.
[0045] In the description of the present disclosure, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present disclosure.
[0046] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present disclosure and are not intended to limit the scope of the present disclosure. For those skilled in the art, other changes or modifications can be made based on the above disclosure, and these changes or modifications are still within the scope of the present disclosure.
