Technical Field

[0001] The utility model belongs to the technical field of textile fabrics, and particularly relates to a multifunctional windproof, rainproof, warm-keeping, sweat-discharging and moisture-permeable composite fabric. Background Technique

[0002] Textile fabrics refer to various materials made through textile processes and are widely used in fields such as clothing, home, and industry; according to the source and processing method of fibers, textile fabrics can be divided into two major categories: natural fabrics and chemical fabrics; natural fabrics include cotton, linen, silk, wool, etc., while chemical fabrics include synthetic fibers such as polyester and nylon; the classification of textile fabrics can also be further subdivided according to their organizational structure, composition, post-finishing, and weaving methods; for example, according to the weaving method, fabrics can be divided into woven fabrics, knitted fabrics, and non-woven fabrics; woven fabrics are woven by arranging warp and weft yarns perpendicular to each other, knitted fabrics are formed by knitting yarns into loops, and non-woven fabrics are made by bonding or stitching loose fibers.

[0003] Traditional windproof and rainproof fabrics have a simple structure and single function, especially poor warm-keeping performance, and are unable to timely discharge the moisture generated when the skin "breathes", increasing the risk of hypothermia in the human body. Based on this, a multifunctional windproof, rainproof, warm-keeping, sweat-discharging and moisture-permeable composite fabric is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multifunctional windproof, rainproof, warm-keeping, sweat-discharging and moisture-permeable composite fabric with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A multifunctional windproof, rainproof, warm-keeping, sweat-discharging and moisture-permeable composite fabric, including a fabric outer layer, an intermediate layer, and a fabric inner layer. The fabric outer layer is a windproof and breathable layer, the intermediate layer is a sweat-discharging and moisture-permeable layer, the fabric inner layer is a warm-keeping and heat-generating layer. The intermediate layer is arranged between the fabric outer layer and the fabric inner layer, and the fabric outer layer, the intermediate layer, and the fabric inner layer are compounded by a lamination process.

[0007] As a further optimized scheme of the utility model, the fabric outer layer is made of high-density nylon fabric, including a water-repellent layer and ultra-fine nylon filaments. The water-repellent layer is impregnated with hydrophobic porous polymer on the filaments of ultra-fine nylon filaments, and the filaments of ultra-fine nylon filaments with the water-repellent layer are woven into the fabric outer layer by a warp and weft weaving method.

[0008] As a further optimized scheme of the utility model, the intermediate layer is a pore-free breathable TPU film. The TPU film has elasticity, silica additives are added in the TPU film, and the thickness of the TPU film is at the nanometer level.

[0009] As a further optimization scheme of the present utility model, the inner layer of the fabric comprises aerogel fiber strands and X-shaped cross-section yarns, and the aerogel fiber strands and the X-shaped cross-section yarns are intertwined to form the inner layer of the fabric.

[0010] As a further optimization scheme of the present utility model, the aerogel fiber strands are made of graphene aerogel fiber yarns and combed wool yarns that are twisted together.

[0011] As a further optimization scheme of the present utility model, the X-shaped cross-section yarns are made by twisting hollow fibers added with far-infrared absorbents.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The present utility model uses silk threads of superfine nylon filaments with a water-repellent layer to weave the outer layer of the fabric, endowing the outer layer of the fabric with excellent properties of wind and rain resistance, breathability and wear resistance. Graphene aerogel fibers endow the inner layer of the fabric with the characteristics of warmth retention, antistatic property and moisture absorption and heat generation.

[0017] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following detailed embodiments are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0018] Embodiment

[0019] As Figure 1 and Figure 2As shown, a multifunctional weatherproof, warm, sweat-wicking and moisture-permeable composite fabric includes a fabric outer layer 1, an intermediate layer 2 and a fabric inner layer 3. The fabric outer layer 1 is a windproof and breathable layer, the intermediate layer 2 is a sweat-wicking and moisture-permeable layer, and the fabric inner layer 3 is a warm and heat-generating layer. The intermediate layer 2 is arranged between the fabric outer layer 1 and the fabric inner layer 3, and the fabric outer layer 1, the intermediate layer 2 and the fabric inner layer 3 are composite by a lamination process; The fabric outer layer 1 is made of high-density nylon fabric, including a water-repellent layer 101 and ultra-fine nylon filaments 102. The water-repellent layer 101 impregnates the filaments of the ultra-fine nylon filaments 102 with a hydrophobic porous polymer. The filaments of the ultra-fine nylon filaments 102 with the water-repellent layer 101 are woven into the fabric outer layer 1 by a warp and weft knitting method;

[0020] It should be noted that the use of the ultra-fine nylon filaments 102 significantly increases the knitting density and reduces the pore diameter, thereby endowing the fabric outer layer 1 with excellent properties of light weight, wear resistance and breathability. When the water-repellent layer 101 impregnates the filaments of the ultra-fine nylon filaments 102 with a hydrophobic porous polymer, the hydrophobic porous polymer ensures the unidirectional moisture permeability of the fabric outer layer 1. Even in a windy and rainy environment, it can breathe efficiently, greatly improving the comfort of the fabric; Each filament of the ultra-fine nylon filaments 102 has been treated with water repellency, and the waterproof index of the entire fabric outer layer 1 can reach 20000mmH2O, which can prevent heavy rain.

[0021] As Figure 1 and Figure 2 shown, the intermediate layer 2 is a pore-free breathable TPU film 201. The TPU film 201 has elasticity. Silica additives are added into the TPU film 201, and the thickness of the TPU film 201 is at the nanometer level.

[0022] It should be noted that the TPU film 201 is prepared by a blow molding process, and the silica additive is used as a water absorption desiccant; Therefore, the intermediate layer 2 has a small thickness, a large surface area and good adsorption, which can promote the absorption and volatilization of water molecules and is a good moisture-permeable layer; The intermediate layer 2 made of the TPU film 201 prepared by the blow molding process has high elastic setting characteristics, which can firmly adhere to the fabric outer layer 1 and the fabric inner layer 3, ensuring the effectiveness and firmness of the lamination process.

[0023] As Figure 1 and Figure 2As shown in the figure, the inner layer 3 of the fabric includes aerogel fiber strands 301 and X-shaped cross-section yarns 302. The aerogel fiber strands 301 and the X-shaped cross-section yarns 302 are intertwined to form the inner layer 3 of the fabric. The aerogel fiber strands 301 are made of graphene aerogel fiber yarns and combed wool yarns twisted together. The graphene material has the properties of conductivity, near-infrared absorption, and far-infrared emission. The conductivity makes it difficult for the inner layer 3 of the fabric to generate static electricity by rubbing against the skin. The near-infrared absorption property greatly improves the utilization rate of sunlight by the inner layer 3 of the fabric and can convert light energy into heat energy. The far-infrared emission property can prevent the loss of human body heat and endows the inner layer 3 of the fabric with good heat preservation effect. The porous structure of the aerogel greatly increases the surface area of the fiber, which can not only retain air but also promote the discharge of sweat. Therefore, the graphene aerogel fiber yarn has excellent properties of antistatic, moisture absorption and heat generation, heat insulation and heat preservation. The combed wool yarn is natural wool fiber, which is both warm and harmless to the human skin. The X-shaped cross-section yarn 302 is made by twisting hollow fibers added with far-infrared absorbent. The hollow structure of the hollow fiber and the aerogel structure of the graphene aerogel fiber yarn act synergistically to be both heat-insulating and breathable. The X-shaped cross-section yarn 302 has good stability, and the inner layer 3 of the fabric is not easy to wrinkle. The X-shaped cross-section yarn 302 added with far-infrared absorbent also has the property of far-infrared emission, which can not only insulate heat and keep warm, but also effectively inhibit the growth of bacteria.

[0024] When in use, since the outer layer 1 of the fabric is woven by the waterproof layer 101 and the superfine nylon filaments 102 impregnated with a hydrophobic porous polymer, it can prevent heavy rain. The superfine nylon filaments 102 adopt a tight warp and weft weaving method, which makes the outer layer 1 of the fabric have good breathability and at the same time realizes the lightweight of the outer layer 1 of the fabric. The middle layer 2 has excellent elasticity and remarkable moisture permeability, which can maximize the comfort of the sports personnel. The graphene aerogel fiber has the characteristics of antistatic, moisture absorption and heat generation, moisture conduction and breathability, heat insulation and heat preservation. The X-shaped cross-section yarn 302 added with far-infrared absorbent also has the properties of heat insulation and heat preservation, moisture conduction and breathability. In addition, it endows the inner layer 3 of the fabric with good wrinkle resistance and antibacterial properties.

[0025] To sum up, this three-layer composite fabric can integrate the three functions of resisting wind and rain, discharging sweat and moisture, and keeping warm. In addition, the composite fabric also has properties such as stain resistance, antistatic, wrinkle resistance, and antibacterial properties, which can effectively protect the life safety of outdoor adventure personnel in extremely cold environments.

[0026] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention.
