Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a moisture-permeable fabric. Background Art

[0002] Moisture-permeable fabric is a kind of fabric with unique functions. Its main feature is that while maintaining waterproof performance, it allows water vapor, that is, sweat emitted by the human body, to pass through the fabric in gaseous form, thereby achieving the effect of breathability and moisture permeability.

[0003] In the prior art, breathable fabrics are usually multi-layer fabrics formed by bonding a film with waterproof and breathable functions to other fabrics through adhesives. The breathability of existing breathable fabrics is mainly determined by the breathable film used. The breathable film's breathability is usually divided into low, medium and high permeability. The cost of films with different breathability is different. The cost of high breathable film is high. Therefore, the cost of high breathable fabrics in the prior art is greatly affected by the breathable film. Moreover, if the lining is made of more than 150G / M 2 When using fabrics such as sweat cloth, fleece or polar fleece, even if a high moisture permeability membrane is used, the moisture permeability of the finished product is unlikely to have a high moisture permeability function. Utility Model Content

[0004] The purpose of the utility model is to provide a moisture permeable fabric that can solve the problem that the moisture permeability of the existing moisture permeable fabrics described in the background art is determined by the moisture permeability of the moisture permeable film, the existing high moisture permeable fabrics are expensive, and for some linings, even if a high moisture permeable film is used, the moisture permeability of the finished product is difficult to have a high moisture permeability function.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A moisture-permeable fabric comprises a first fabric layer, a second fabric layer and a third fabric layer, wherein the second fabric layer is a moisture-permeable membrane, the first fabric layer is a fabric treated by water splashing, and the third fabric layer is a fabric treated by moisture absorption and quick drying. The first fabric layer, the second fabric layer and the third fabric layer are sequentially bonded and fixedly connected by hot melt adhesive.

[0007] In the above solution, the first fabric layer has a gram weight of 80g / m 2 -120g / m 2 Polyester fabric.

[0008] In the above solution, the second fabric layer is a low-permeability moisture-permeable film, a medium-permeability moisture-permeable film, or a high-permeability moisture-permeable film.

[0009] In the above solution, the second fabric layer is a TPU medium-transparent film with a thickness of 8UM-20UM.

[0010] In the above solution, the third fabric layer is a jersey, fleece, polar fleece or a material with a gram weight of 130g / m 2 -180g / m 2 Polyester knitted fabric.

[0011] The present invention has positive effects: 1) The breathable fabric of the present invention, the outermost first fabric layer adopts the fabric that has been treated with water splashing, so that the obtained breathable fabric has better waterproof performance, and the innermost third fabric layer adopts the fabric that has been treated with moisture absorption and quick drying, so that it has better moisture absorption performance. Through this improvement, the moisture permeability of the breathable fabric can be largely determined by the performance of the innermost third fabric layer. Without the need to improve the moisture permeability of the second fabric layer, the moisture permeability of the fabric can be improved, thereby achieving a significant improvement in the moisture permeability of the fabric at a lower cost; 2) The breathable fabric of the present invention can be used not only in the case where the third fabric is ordinary fabric, but also in the case of moisture-absorbing sweat cloth, fleece, polar fleece or 130g / m2 fabric that has a greater impact on moisture absorption performance. 2 -180g / m 2 The polyester knitted fabric or other thermal insulation fabrics can be made into a fabric with good moisture permeability and good thermal insulation performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic structural diagram of the moisture-permeable fabric of the present invention.

[0013] The reference numerals in the figure are a first fabric layer 1 , a second fabric layer 2 , and a third fabric layer 3 . DETAILED DESCRIPTION

[0014] The following examples clearly and completely describe the technical solutions of the present invention. Obviously, the examples described are only a portion of the embodiments of the present invention, not all of them. Based on the examples of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0015] like Figure 1 As shown, the moisture-permeable fabric of the present invention includes a first fabric layer 1, a second fabric layer 2 and a third fabric layer 3. The first fabric layer 1, the second fabric layer 2 and the third fabric layer 3 are sequentially bonded and fixedly connected by hot melt adhesive.

[0016] The second fabric layer 2 is a moisture-permeable film, and the second fabric layer 2 can be made of a low-permeability moisture-permeable film, a medium-permeability moisture-permeable film, or a high-permeability moisture-permeable film. For example, the second fabric layer 2 can be made of a TPU medium-permeability film.

[0017] The first fabric layer 1 can be selected with a weight of 80g / m2 -120g / m 2 The polyester fabric of the first fabric layer 1 can preferably be made of fabric that has been treated with water after splashing, and the water after splashing can be treated with a fluorine-free waterproofing agent. The fluorine-free waterproofing agent can be a polyurethane water repellent, a modified acrylic water repellent, or a paraffin modified fluorine-free water repellent.

[0018] The third fabric layer 3 is a fabric that has been post-treated for moisture absorption and quick drying. The method of post-treatment for moisture absorption and quick drying is: adding a hydrophilic additive during dyeing by padding to allow the hydrophilic additive to undergo a hydrophilic copolymerization reaction with the fiber, thereby forming a hydrophilic layer on the fiber surface, thereby giving the fabric a moisture absorption and quick drying function.

[0019] The third fabric layer 3 can be made of ordinary textile fabrics, which can have good moisture permeability after being treated with moisture absorption and quick drying. The third fabric layer 3 can also be made of sweat cloth, fleece, polar fleece or a weight of 130g / m 2 -180g / m 2 The polyester knitted fabric makes the warm fabric also have good moisture permeability.

[0020] The following example illustrates the preparation method of the moisture-permeable fabric of the present invention:

[0021] The first fabric layer 1 is made of 100% polyester, 50Denier*50Denier, density 330T, weight 80g / m 2 ;

[0022] The second fabric layer 2 is made of 100% TPU material and 20UM thick medium transparent film;

[0023] The third fabric layer 3 is made of 100% polyester with a gram weight of 160g / m 2 polar fleece;

[0024] The waterproof post-treatment method of the first fabric layer 1 is to use a mixture of a fluorine-free waterproofing agent and a wetting agent to splash water on the fabric, the concentration of the waterproofing agent in the mixture is 60g / L, the concentration of the wetting agent is 15g / L, and the pH of the mixture is adjusted to 4-5 with citric acid. It is then subjected to front-stage baking and back-stage baking treatment, and the vehicle speed is 30m / min.

[0025] The first fabric layer 1 and the second fabric layer 2 are bonded together using hot melt adhesive at a bonding temperature of 95°C-100°C, a speed of 25 m / min, and a bonding pressure of 2-5 MPa. The bonded fabrics are steam-cured and then cured.

[0026] The third fabric layer 3 is subjected to a moisture absorption and quick-drying treatment by adding a hydrophilic additive during dyeing by padding, so that the hydrophilic additive undergoes a hydrophilic copolymerization reaction with the fiber, forming a hydrophilic layer on the fiber surface, thereby giving the fabric a moisture absorption and quick-drying function.

[0027] The third fabric layer 3 that has been treated with moisture absorption and quick drying is bonded to the back of the second fabric layer 2 by hot melt adhesive. The bonding temperature is 100°C, the vehicle speed is 25m / min, and the bonding pressure is 2-5MPa.

[0028] The moisture-permeable fabric of the present invention has an outermost first fabric layer 1 made of fabric that has been treated with water splashing, so that the obtained moisture-permeable fabric has better waterproof performance, and the innermost third fabric layer 3 is made of fabric that has been treated with moisture absorption and quick drying, so that it has better moisture absorption performance. Through this improvement, the moisture permeability of the moisture-permeable fabric can be largely determined by the performance of the innermost third fabric layer 3. Without improving the moisture permeability of the second fabric layer 2, the moisture permeability of the fabric can be improved, thereby achieving a significant improvement in the moisture permeability of the fabric at a lower cost.

[0029] The moisture-permeable fabric of the utility model can be used not only when the third fabric 3 is a common fabric, but also when it is used for moisture-absorbing sweat cloth, fleece, polar fleece or other fabrics with a gram weight of 130g / m2 that have a greater influence on moisture absorption performance. 2 -180g / m 2 The polyester knitted fabric or other thermal insulation fabrics can be made into a fabric with good moisture permeability and good thermal insulation performance.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
