Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, and in particular to a moisture-absorbing and quick-drying fabric and a knitting method thereof. Background Art

[0002] The sweat-proof layer of existing clothing on the market is usually waterproof fabric or three-proof (waterproof, oil-proof, and anti-fouling) fabric. The three-proof fabric, as shown in the Chinese invention patent with application number 201410474229.9, includes a coating fabric layer, an adhesive layer, and a coating base material layer arranged from top to bottom. The coating base material layer is coated with a UV finishing agent, an anti-wrinkle finishing agent, and a cross-linking agent, and has the three-proof functions of UV protection, wrinkle resistance, and waterproofness. Clothing made of this three-proof fabric is difficult to absorb sweat stains, which will cause sweat stains to adhere to the skin surface, affecting wearing comfort. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a moisture-absorbing quick-drying fabric and a knitting method thereof.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a moisture-absorbing quick-drying fabric, comprising a water-repellent layer, a drainage layer and a hydrophilic layer arranged in sequence, and the surface of the water-repellent layer is provided with mesh holes.

[0005] Another technical solution adopted by the present invention is: a weaving method of the above-mentioned moisture-absorbing and quick-drying fabric, wherein the water-repellent layer is woven from a first fiber, the drainage layer is woven from a second fiber, and the hydrophilic layer is woven from a third fiber; the second fiber is interwoven with the first fiber and the third fiber to connect the water-repellent layer and the hydrophilic layer.

[0006] The beneficial effects of the present invention are as follows: the moisture-absorbing quick-drying fabric of the present invention absorbs sweat through the hydrophilic layer, and the sweat of the hydrophilic layer enters the water-repellent layer through the drainage layer and is discharged from the mesh holes on the surface of the water-repellent layer, thereby achieving moisture absorption and perspiration discharge; since the water-repellent layer has no water absorption effect, the surface layer of the fabric of the present invention always remains dry. DETAILED DESCRIPTION

[0007] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes.

[0008] A moisture-absorbing quick-drying fabric comprises a water-repellent layer, a drainage layer and a hydrophilic layer which are arranged in sequence, and mesh holes are arranged on the surface of the water-repellent layer.

[0009] From the above description, it can be seen that the beneficial effect of the present invention is that the moisture-absorbing and quick-drying fabric of the present invention has no sweat stains and moisture-absorbing and quick-drying properties. The hydrophilic layer is used to contact the skin, and the sweat generated by the skin is absorbed by the hydrophilic layer, and then enters the water-repellent layer through the drainage layer. Since the water-repellent layer has no water absorption effect, the sweat can only be discharged from the mesh holes on the surface of the water-repellent layer to achieve moisture absorption and perspiration. During this process, the water-repellent layer always remains dry. The clothing always maintains a clean and tidy appearance during wearing. Even in the case of heavy sweating, there will be no embarrassing sweat stains, avoiding problems such as fading, yellowing or deformation of the fabric caused by sweat stains; and because there is no sweat stain residue, there is no need to use too much detergent or perform special treatment to remove stubborn sweat stains during the washing process, thereby extending the service life of the clothing.

[0010] Another technical solution adopted by the present invention is: in the weaving method of the above-mentioned moisture-absorbing and quick-drying fabric, the water-repellent layer is woven from the first fiber, the drainage layer is woven from the second fiber, and the hydrophilic layer is woven from the third fiber; the second fiber is interwoven with the first fiber and the third fiber to connect the water-repellent layer and the hydrophilic layer.

[0011] Further, part of the first fibers are interwoven with the third fibers but not interwoven with the second fibers to form a mesh.

[0012] From the above description, it can be seen that part of the first fibers are not interwoven with the second fibers, but are pulled down to the hydrophilic layer to form a collection loop with the third fibers, forming a mesh on the surface of the water-repellent layer to achieve perspiration of the water-repellent layer.

[0013] Furthermore, the proportion of mesh holes in the water-repellent layer is 10~41 / cm 2 .

[0014] Furthermore, the mesh aperture is less than 0.07 cm.

[0015] Furthermore, each mesh has only one stitch of the first fiber interwoven with the third fiber.

[0016] From the above description, we can know that if there are too many meshes, the water-repellent layer will not dry well, and if there are too few meshes, the moisture absorption and perspiration effect will not be good. Therefore, the proportion of meshes in the water-repellent layer is controlled to be 10~41 / cm 2 .

[0017] Furthermore, the first fibers include waterproof fibers.

[0018] Furthermore, the third fiber includes at least two fibers with different D numbers.

[0019] From the above description, it can be seen that the hydrophilic layer is interwoven with a variety of fibers with different D numbers. Due to the different thicknesses of the various fibers, the hydrophilic layer presents concave and convex changes, which can reduce the contact area between the hydrophilic layer and the skin and improve wearing comfort.

[0020] Furthermore, the first fiber and the third fiber both include spandex.

[0021] From the above description, it can be seen that the addition of spandex makes the fabric have better elasticity and feel, and improves the waterproof effect of the water-repellent layer.

[0022] Further, the D number of the spandex is smaller than that of the other fibers in the first fiber and the third fiber.

[0023] From the above description, it can be seen that the spandex has a small D number and can be hidden inside the fabric without affecting the waterproof property of the first fiber and the hydrophilic property of the third fiber.

[0024] Furthermore, the second fibers have a fineness greater than that of the third fibers.

[0025] From the above description, it can be seen that the fineness of the second fiber is greater than that of the third fiber, so the hygroscopicity of the conductive layer is lower than that of the hydrophilic layer. Sweat is transferred along the hydrophilic layer to the conductive layer, quickly absorbing sweat stains on the body surface, achieving a dry and comfortable effect on the skin surface.

[0026] Furthermore, the third fiber has a fineness of 1-2 dpf.

[0027] From the above description, it can be seen that the third fiber has a fineness of 1~2dpf, has a high siphon effect, and can conduct moisture.

[0028] Furthermore, the minimum loop knitting structure is 12-way, and the arrangement of the knitting needles during knitting includes: the arrangement order of the upper needle disk is AB, and the arrangement order of the lower needle cylinder is BA, wherein A represents high heel needles and B represents low heel needles.

[0029] Furthermore, the 2nd, 5th, 8th and 11th routes are connected to the first fiber, the 1st, 4th, 7th and 10th routes are connected to the second fiber, and the 3rd, 6th, 9th and 12th routes are connected to the third fiber.

[0030] Furthermore, the low heel needle of the needle disc on the first route is a looping organization and the high heel needle of the lower needle cylinder is a tuck organization, and the high heel needle of the upper needle disc and the low heel needle of the lower needle cylinder are a floating thread organization; On the 7th line, the low heel needle of the needle plate and the high heel needle of the lower needle cylinder are tuck stitches, and the high heel needle of the upper needle plate and the low heel needle of the lower needle cylinder are floating stitches; On the 4th and 10th routes, the low heel needles on the needle plate and the high heel needles on the lower needle cylinder are floating thread organizations, and the high heel needles on the upper needle plate and the low heel needles on the lower needle cylinder are tucked loop organizations; The high heel and low heel needles on the 2nd, 5th, 8th and 11th needle discs are loop-forming tissues, and the high heel and low heel needles on the lower needle cylinder are floating thread tissues; The high heel needles and low heel needles on the 3rd, 6th, 9th and 12th needle dials are floating thread organizations, and the high heel needles and low heel needles on the lower needle cylinder are loop forming organizations.
