Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically a waterproof textile fabric. Background Technology

[0002] As people's living standards and quality of life continue to improve, their requirements for the comfort, aesthetics, and functionality of clothing are also constantly increasing, and functional textiles are gradually becoming the mainstream of modern social development.

[0003] Currently, the waterproof layer of traditional waterproof textile fabrics is mostly made of waterproof membrane materials or polytetrafluoroethylene (PTFE) fibers. Although waterproof membrane materials can play a waterproof role, they are expensive and have poor breathability. On the other hand, the waterproof layer woven from PTFE fibers has poor heat insulation and is easily damaged, resulting in high cost and poor functionality of waterproof textile fabrics. Therefore, a new type of waterproof textile fabric is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and address the problems existing in the existing technology, this utility model proposes a waterproof textile fabric.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The waterproof textile fabric of this utility model includes a fabric body composed of a water-repellent outer layer, a moisture-wicking interlayer and a moisture-absorbing inner layer; the water-repellent outer layer and the moisture-absorbing inner layer are respectively bonded to the upper and lower sides of the moisture-wicking interlayer by materials.

[0006] The outer layer, opposite to the water-repellent interlayer, is roughened to form a fluffy layer, and the inner moisture-absorbing layer has evenly distributed air pores.

[0007] The water-repellent outer layer includes a textile base layer, on which a textile surface layer is bonded by a material, and the pile layer is disposed on the surface of the textile surface layer. A biomimetic coating is applied between the textile base layer and the biomimetic coating.

[0008] The ventilating interlayer includes an upper breathable layer, a lower breathable layer sewn below the upper breathable layer, and an insulation layer filling the gap between the upper and lower breathable layers.

[0009] Preferably, the textile bottom layer is made of polyester low-elasticity yarn using a high-density textile process, and the textile surface layer is made of nylon semi-dull yarn using a high-density textile process.

[0010] Preferably, the slurry interlayer is made of silica biomimetic material, and both the textile bottom layer and the textile top layer are treated with C6 waterproofing agent.

[0011] Preferably, the upper breathable layer is a polyester Oxford cloth layer, the lower breathable layer is a polyester mesh layer, and the heat insulation layer is a polyester staple fiber wadding layer.

[0012] Preferably, the moisture-absorbing inner layer comprises a blended fabric layer, and the air-permeable holes are disposed on the blended fabric layer.

[0013] Preferably, the blended fabric layer is made of cotton, polyester and spandex blended in a certain proportion.

[0014] Preferably, the blended fabric layer is impregnated with a cationic surfactant to make the material surface hydrophilic.

[0015] The advantages of this utility model are:

[0016] This invention utilizes a high-density woven fabric with micropores in the underlayer and surface layers. These pores ensure breathability while providing physical waterproofing. A biomimetic coating forms a waterproof layer on the underlayer. The upper and lower breathable layers exchange gases through the natural gaps in their fibers, thus achieving fabric breathability. An insulation layer is filled between the two layers, ensuring both micro-breathability and warmth. By combining conventional materials and basic processes, this invention avoids the use of expensive materials, effectively reducing production costs and making more functional textile fabrics available to a wider range of people.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] For examples, please refer to Figure 1-4 As shown, a waterproof textile fabric includes a main body of fabric composed of a water-repellent outer layer 1, a moisture-wicking interlayer 2, and a moisture-absorbing inner layer 3; the water-repellent outer layer 1 and the moisture-absorbing inner layer 3 are respectively bonded to the upper and lower sides of the moisture-wicking interlayer 2 by means of materials.

[0027] The outer surface of the water-repellent outer layer 1, opposite to the drainage interlayer 2, is roughened to form a fluffy layer 14, and the moisture-absorbing inner layer 3 has evenly distributed air pores 32.

[0028] The water-repellent outer layer 1 includes a textile base layer 11, on which a textile surface layer 13 is bonded by a material, and a pile layer 14 is disposed on the surface of the textile surface layer 13. A biomimetic coating 12 is coated between the textile base layer 11 and the biomimetic coating 12.

[0029] The ventilating interlayer 2 includes an upper breathable layer 21, a lower breathable layer 22 sewn below the upper breathable layer 21, and a heat insulation layer 23 filling the gap between the upper breathable layer 21 and the lower breathable layer 22.

[0030] The textile bottom layer 11 is made of polyester low-elasticity yarn using a high-density textile process, and the textile top layer 13 is made of nylon semi-dull yarn using a high-density textile process.

[0031] The slurry interlayer 2 is made of silicon dioxide biomimetic material, and both the textile bottom layer 11 and the textile top layer 13 are treated with C6 waterproofing agent.

[0032] The upper breathable layer 21 is a polyester Oxford cloth layer, the lower breathable layer 22 is a polyester mesh layer, and the heat insulation layer 23 is a polyester short fiber wadding layer.

[0033] The moisture-absorbing inner layer 3 includes a blended fabric layer 31, and the air vents 32 are disposed on the blended fabric layer 31.

[0034] The blended fabric layer 31 is made of cotton, polyester and spandex blended in a certain proportion.

[0035] The blended fabric layer 31 is hydrophilicized by impregnation with cationic surfactants.

[0036] In practice, the waterproof layer of traditional waterproof textile fabrics is mostly made of waterproof membrane materials or woven polytetrafluoroethylene (PTFE) fibers. While waterproof membrane materials can provide waterproofing, they are expensive and have poor breathability. PTFE fiber-woven waterproof layers have poor heat insulation and are easily damaged, resulting in expensive and less functional waterproof textile fabrics. In this solution, a high-density woven textile bottom layer 11 and textile surface layer 13 form micropores. These pores ensure breathability while providing physical waterproofing. Furthermore, a napped layer 14 is formed on the surface of textile surface layer 13, creating a feather-like waterproof effect. The nap in the nap layer 14 prevents water from directly contacting the fabric. Under the action of the biomimetic coating 12, a waterproof coating is formed on the textile bottom layer 11. This coating is fixed to the fiber surface using bio-enzyme cross-linking technology, preventing water from penetrating downwards into the drainage layer 2, thereby improving the waterproof effect of the fabric and making the waterproof effect more durable.

[0037] The upper breathable layer 21 and the lower breathable layer 22 form a slurry interlayer 2. The upper breathable layer 21 and the lower breathable layer 22 exchange gases through the natural gaps in their fibers, thereby achieving the breathability of the fabric. An insulation layer 23 is filled between the two layers and fixed by quilting to form an air gap, which can ensure micro-breathability while also maintaining warmth.

[0038] Finally, by blending cotton, polyester and spandex in a certain proportion to form a blended fabric layer 31, the surface of the fabric in contact with the human body is made more skin-friendly and comfortable. The material is impregnated with cationic surfactants to improve the moisture absorption rate of the blended fabric layer 31. At the same time, combined with the natural moisture absorption effect of cotton fibers, it can quickly absorb the sweat excreted by the human body. With the setting of breathable holes 32, the sweat excretion effect is further improved, making people more comfortable to wear.

[0039] By combining conventional materials and basic processes, the use of expensive materials is avoided, which effectively reduces production costs and makes it possible for more people to use textile fabrics with better functionality.

[0040] This combination has achieved the effect of reducing production costs, and at the same time, it has effectively improved the functionality of textile fabrics.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
