[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present embodiment discloses a unidirectional moisture-conducting fabric, comprising a surface layer 100 and an inner layer 200 arranged in sequence from the outside to the inside, wherein the inner layer 200 comprises a first area 201 and a second area 202, wherein the two second areas 202 protrude upward to form triangular top ends, and glue is dispensed at the top ends to connect the inner layer 200 and the base 1022 through glue dispense.

[0029] The first area 201 is recessed downward, and the recess height H is 0.3mm-0.6mm. Preferably, the recess height H is 0.5mm. The first area 201 is recessed downward to form a cavity 300 with the inner side 102 of the surface layer and the inner layer 200. The cavity 300 is in the shape of an inverted trapezoid. The first area 201 is woven with the second yarn 402, and the second yarn 402 is made of polypropylene fiber. Because the fiber cross-section of the polypropylene fiber is circular and the fiber is smooth and has no stripes in the longitudinal direction, moisture cannot penetrate and adsorb. The molecular structure of the polypropylene fiber is relatively tight, so it is not easy for water molecules to penetrate into the internal gaps of the fiber, so that water vapor can be released to the cavity 300 through the first area 201, and the cavity 300 is hollow, so that the water vapor is circulated in the cavity 300 by air, thereby evaporating part of the water vapor, and the remaining water vapor can be adsorbed by the surface layer 100 and discharged to the outside.

[0030] The angle α formed by the two second areas 202 and the inner side 102 of the surface layer is 10°-18°. Preferably, the angle α formed by the two second areas 202 and the inner side 102 of the surface layer is 12°. If the angle formed by the two second areas 202 and the inner side 102 of the surface layer is less than 10°, the space in the cavity 300 will be insufficient to form air circulation due to the small angle. If the angle is greater than 18°, the cavity 300 will be concave downward due to the large angle, thereby making the fabric structure unstable. The second area 202 is woven with the first yarn 401, and the first yarn 401 is made of shaped fiber. Because the cross-sectional structure of the shaped fiber contains micropores and cavities, when it comes into contact with water vapor, it can quickly absorb moisture and transfer it to the surface layer 100 by capillary action. The second area 202 is higher than the first area 201, 1 is combined to form a first area 201 for hydrophobic transmission and a second area 202 for hydrophilic transmission, but the first area 201 surrounds the second area 202, and the first area 201 and the second area 202 are arranged in a matrix, and the area of ​​the second area 202 is smaller than the first area 201, which not only increases the structural stability of the inner layer 200, but also intersperses the hydrophobic part with the hydrophilic part, so that the water vapor penetration and adsorption can be faster, and form multi-directional different transmission channels, so that the water vapor can be transmitted in multiple ways and directions, so that the inner layer 200 can be kept dry continuously, and the inner layer 200 can shorten the residence time of the water vapor by interlacing the first area 201 and the second area 202. When the water vapor contacts, it can be quickly transferred to the fabric surface layer 100 through the siphon of the second area 202, so that the inner layer 200 close to the skin can be quickly dry.

[0031] The surface layer 100 includes an outer surface layer 101 and an inner surface layer 102. The surface layer 100 is woven with hydrophilic fibers. The inner surface layer 102 includes meshes 1021 and a base 1022. The meshes 1021 are also arranged in a matrix on the base 1022, and the meshes 1021 are located above the center of the first area 201. Therefore, the meshes 1021 are also located above the center of the cavity 300. Therefore, when the first area 201 transports water vapor to the cavity 300, the water vapor passes through the hydrophilic fibers on the inner surface layer 102. However, because the inner side 102 of the surface layer is interrupted by the mesh 1021, the water vapor adsorbed by the hydrophilic fibers on the inner side 102 of the surface layer will not be too saturated, and the water vapor can directly contact the outer side 101 of the surface layer more quickly through the mesh 1021, so that the inner side 102 of the surface layer can continuously penetrate and absorb moisture, and the outer side 101 of the surface layer is also woven with hydrophilic fibers. Therefore, the outer side 101 of the surface layer absorbs the water vapor that penetrates the inner side 102 of the surface layer, and evaporates through the outside to keep the fabric dry.

[0032] The first area 201 in the inner layer 200 is woven with the second yarn 402, which is made of polypropylene fiber. The second area 202 is woven with the first yarn 401, which is made of shaped fiber. The surface layer 100 is made of hydrophilic fiber, which is polyester fiber with enhanced twist, so that grooves are formed in the cross-section of the polyester fiber, so that the surface layer 100 can penetrate and absorb more water vapor.

[0033] The inner layer 200 has 4 rows of stitches as one cycle, each row of stitches including a first yarn 401 and a second yarn 402. Figure 1 :1, and each row of loops of the inner layer 200 also includes an upper needle and a lower needle, and the first yarn 401 is tucked on the 1st and 3rd upper needles of the 1st and 3rd row of loops, and looped on the 2nd and 4th lower needles, and the second yarn 402 is looped on the 1st and 3rd upper needles of the 2nd and 4th row of loops, and tucked on the 2nd and 4th lower needles, so that the first yarn 401 is knitted to form the second area 202, and the second yarn 402 is knitted to form the first area 201, and the width of the first area 201 is made greater than that of the second area 202. Because each row has tucks, the first area 201 and the second area 202 form a structure of different densities, so that water vapor can quickly diffuse to the surface layer 100 when it contacts.

[0034] The surface layer 100 has 6 rows of stitches as one cycle, and each row of stitches has only one yarn, but each row of stitches includes an upper needle and a lower needle. The 1st, 3rd, 5th, and 7th upper needles of the 1st and 2nd rows of stitches form a loop, and the 2nd, 4th, 6th, and 8th lower needles form a loop. The 1st and 2nd rows of stitches are repeated 12 times. The 1st, 3rd, 5th, and 7th upper needles of the 3rd to 6th rows of stitches form a loop, and the 2nd lower needle is tucked. The 4th lower needle is not knitted, and the 6th and 8th lower needles form a loop. The 5th, 6th, 7th, and 8th needles of the 3rd to 6th rows of stitches need to be repeated 12 times. The mesh 1021 is formed by tucking the 2nd lower needle of the 3rd to 6th rows of stitches. Because of the loop of the number of stitches, the mesh 1021 is located above the center of the first area 201, and The inner layer 200 is woven in this way so that the first area 201 and the second area 202 form a tree-like forked structure, and the first area 201 is hydrophobic, and the second area 202 is hydrophilic, and a cavity 300 is formed between the inner layer 200 and the surface layer 100, so that when the inner layer 200 and the surface layer 100 contact water vapor, multi-level connecting channels are formed, which not only improves the water vapor transportation efficiency, but also accelerates the evaporation of water vapor, thereby increasing the air permeability of the fabric. Because the inner layer 200 adopts polypropylene fiber and heterosexual fiber, the polypropylene fiber does not absorb water, and the siphon of the heterosexual fiber can only transport it to the polyester fiber of the surface layer 100. Therefore, when external water vapor contacts, the water vapor will not be backed up to affect the moisture conductivity of the fabric.

[0035] The double-layer structure of the surface layer 100 and the inner layer 200 is woven, and therefore the surface layer 100 and the inner layer 200 are experimentally rated by the dynamic moisture transfer method according to the performance index data of GB / T21655.2 (see Tables 1 and 2). The multi-level interconnected channels formed by the combination of the surface layer 100 and the inner layer 200 improve the hygroscopicity and moisture conductivity of the fabric, and at the same time increase the moisture diffusion rate of the fabric, so that the unidirectional moisture conductivity of the fabric is not formed by the coating, thereby increasing the environmental protection and practicality of the fabric.
