[0046] A second connection point 500 and a second gap 510 . DETAILED DESCRIPTION

[0047] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0048] Example 1

[0049] A versatile fabric, such as Figure 1 As shown, a waterproof and breathable surface layer 100, a waterproof and breathable middle layer 200 and a knitted bottom layer 300 are provided, and the waterproof and breathable surface layer 100, the waterproof and breathable middle layer 200 and the knitted bottom layer 300 are stacked in sequence. The waterproof and breathable surface layer 100 is a textured fabric with a concave-convex structure.

[0050] The waterproof and breathable surface layer 100 and the waterproof and breathable middle layer 200 are connected through a plurality of first connection points 400, and the first connection points 400 are distributed between the waterproof and breathable surface layer 100 and the waterproof and breathable middle layer 200. There are first gaps 410 for ventilation between the first connection points 400 and the adjacent first connection points 400.

[0051] The waterproof and breathable middle layer 200 and the knitted bottom layer 300 are connected via a plurality of second connection points 500, and the second connection points 500 are distributed between the waterproof and breathable middle layer 200 and the knitted bottom layer 300. A second gap 510 for ventilation exists between the second connection point 500 and the adjacent first connection point 400.

[0052] It should be noted that the utility model connects the waterproof and breathable surface layer 100, the waterproof and breathable middle layer 200 and the knitted bottom layer 300 through the first connection point 400 and the second connection point 500, and the first connection point 400 and the waterproof and breathable surface layer 100 and the waterproof and breathable middle layer 200 are point connections, and there are a large number of first gaps 410; similarly, the second connection point 500 and the water-permeable middle layer and the knitted bottom layer 300 are also point connections, and there are also a large number of second gaps 510. These gaps can quickly conduct gas to the waterproof and breathable surface layer 100, the waterproof and breathable middle layer 200 and the knitted bottom layer 300, thereby improving the ventilation effect. Moreover, the first connection point 400 and the second connection point 500 are distributed in the waterproof and breathable surface layer 100, the waterproof and breathable middle layer 200 and the knitted bottom layer 300 to achieve effective connection of the three layers.

[0053] The waterproof and breathable surface layer 100 of the utility model is a textured fabric with a concave-convex structure. Compared with a relatively flat and tight structure, the concave-convex structure of the waterproof and breathable surface layer 100 has a larger gap with the waterproof and breathable middle layer 200, thereby having a certain air permeability. More importantly, the concave-convex structure of the waterproof and breathable surface layer 100 can effectively improve the air permeability compared with a relatively flat and tight structure.

[0054] The waterproof and breathable surface layer 100 is a waterproof and breathable surface layer 100 that is water-repellent, anti-fouling and easy to decontaminate by paraffin and acrylic polymer.

[0055] It should be emphasized that it is common knowledge for those skilled in the art to use paraffin and acrylic polymers to finish the fabrics with water-repellent, stain-resistant and easy-to-remove properties. Paraffin and acrylic polymers as water-repellent, stain-resistant and easy-to-remove properties are routine operations in the field of fabric technology. The utility model does not improve the water-repellent, stain-resistant and easy-to-remove property finishing process, but uses common fabrics that have been treated with water-repellent, stain-resistant and easy-to-remove properties as the waterproof and breathable surface layer 100 of the utility model. Through this waterproof and breathable surface layer 100, the fabric of the utility model has water-repellent, stain-resistant and easy-to-remove properties.

[0056] In order to facilitate understanding by non-technical personnel, the utility model introduces the principle of paraffin and acrylic polymer, wherein the waterproof principle of paraffin is based on its electrostatic properties. There are many polar groups and non-polar groups in paraffin molecules, which are more sensitive to polarity. Therefore, when encountering water, water molecules will preferentially combine with the polar groups on paraffin, and will not penetrate into the interior of paraffin. In addition, paraffin molecules themselves are non-polar molecules, and the molecular forces between them are relatively strong, so the penetration speed of water can be slowed down to achieve the effect of resisting penetration. Acrylic polymer has three-dimensional cross-linking and hydrophilic groups. The molecular structure of acrylic acid contains a polar functional group carboxyl (-COOH), which can form hydrogen bonds with surrounding water molecules, thereby showing hydrophilicity. Stains are easy to wash and wipe off, achieving an easy-to-remove stain effect. In addition, the molecular structure is designed to obtain an asymmetric spatial distribution, and the molecules are polar, so that the textiles will appear polar, which has a repelling effect on non-polar oil stains. During the washing process of clothing, the stains can be pushed into the water, thereby having a good easy-to-remove stain effect, and it can have a water-repellent effect when drying, but the waterproof and breathable surface layer 100 does not have a hydrostatic waterproof effect.

[0057] It should be noted that the textured fabric with a concave-convex structure of the utility model can be obtained through different textile processes, such as knitting, jacquard, printing, finishing, etc.

[0058] The waterproof and breathable surface layer of this embodiment is woven from more than 100 warp yarns and more than 100 weft yarns. There are at least two finenesses among all the warp yarns. Two adjacent warp yarns with different finenesses are defined as a pair of warp yarns. There are at least two pairs of warp yarns in the waterproof and breathable surface layer; there are at least two finenesses among all the weft yarns. Two adjacent weft yarns with different finenesses are defined as a pair of weft yarns. There are at least two pairs of weft yarns in the waterproof and breathable surface layer. The fineness of the warp yarn is at least two of 30D, 40D, 50D, 70D, 100D, 150D or 300D; the fineness of the weft yarn is at least two of 30D, 40D, 50D, 70D, 100D, 150D or 300D.

[0059] It should be noted that in this embodiment, the concave-convex structure fabric can be obtained by interweaving warp yarns and weft yarns of different finenesses, that is, by using different yarn counts and thicknesses. This method has a lower process complexity than jacquard. Moreover, the fineness of the warp yarn and the fineness of the weft yarn can be within the above range, as long as the fineness of the warp yarn and the weft yarn is within the above range. In this embodiment, the warp yarn is 30D and 50D, and the weft yarn is 30D and 50D as an example. The waterproof and breathable surface layer of this embodiment is composed of weft yarn pairs and warp yarn pairs arranged in sequence, wherein the warp yarn is arranged as 30D, 50D, 30D, 50D, 30D, 50D, 30D, 50D..., that is, each warp yarn forms a warp yarn pair with the warp yarns on the left and right sides; the weft yarn is arranged as 30D, 50D, 30D, 50D, 30D, 50D, 30D, 50D..., that is, each weft yarn forms a warp yarn pair with the weft yarns on the upper and lower sides.

[0060] The arrangement of the warp yarns of the utility model can also be 30D, 30D, 30D, 50D, 50D, 30D, 30D, 50D, 50D, 50D, 50D, 30D, 30D, 30D, 30D, 30D, ..., that is, when the fineness of adjacent warp yarns is different, the warp yarn and the warp yarns of different fineness form a warp yarn pair; when the fineness is the same as that of the adjacent warp yarns, the two warp yarns do not belong to the warp yarn pair mentioned in the utility model. Similarly, the arrangement of the weft yarns can also be 30D, 30D, 30D, 50D, 50D, 30D, 30D, 50D, 50D, 50D, 30D, 30D, 30D, 30D ..., that is, when the fineness of adjacent weft yarns is different, the weft yarn and the weft yarns of different fineness form a weft yarn pair; when the fineness is the same as that of the adjacent weft yarns, the two weft yarns do not belong to the weft yarn pair mentioned in the utility model.

[0061] The utility model can also define continuous warp yarns of the same fineness as a group of warp yarn groups, and define continuous weft yarns of the same fineness as a group of weft yarn groups. Then the above-mentioned warp yarn groups are 30D, 30D, 30D as a group of warp yarn groups, 50D, 50D as a group of warp yarn groups, 30D, 30D as a group of warp and weft groups, 50D, 50D, 50D, 50D as a group of warp yarn groups, 30D, 30D, 30D, 30D as a group of warp yarn groups, and similarly, the division of weft yarn groups is the same as that of warp yarn groups.

[0062] The warp yarn of this embodiment is at least one of polyester-nylon composite yarn or polyester and nylon coated spandex yarn. The weft yarn is at least one of polyester-nylon composite yarn or polyester and nylon coated spandex yarn. It should be noted that since the composite yarn gives the fabric a soft property, and the hydrophilic and hydrophobic structure and low surface energy of the chemical fiber fabric surface have relatively poor water absorption performance, it has a certain effect of preventing water penetration. This embodiment takes the warp yarn as polyester-nylon composite yarn and the weft yarn as nylon coated spandex yarn as an example.

[0063] The first connection point 400 and the second connection point 500 of the utility model are both polyurethane hot melt adhesive points; the waterproof and breathable middle layer 200 is a polyurethane film.

[0064] It should be noted that, since the particle size of sweat vapor is 0.0004μm, the particle size of fog is 100μm, the particle size of drizzle is 500μm, the particle size of moderate rain is 2000μm, the particle size of heavy rain is 3000μm, and the particle size of torrential rain is 6000μm-10000μm, and polyurethane is a mixture of polybutyl acrylate, polypropylene glycol, and polyvinyl alcohol, with a hydrophobic structure of polyolefin in polyethylene glycol and a hydrophilic structure of ethylene oxide, water molecules cannot pass through, and the hydrophilic groups can absorb moisture, so that in addition to having high waterproof performance, it can also absorb small particles of sweat vapor to freely penetrate the membrane, and large particles of fog, drizzle, moderate rain, heavy rain, torrential rain, etc. cannot pass through the polyurethane membrane structure. Therefore, the waterproof and breathable intermediate layer 200 has a strong waterproof and breathable effect and a significant hydrostatic pressure waterproof effect. Since the multifunctional fabric of the utility model is provided with a waterproof and breathable middle layer 200, the defect that the waterproof and breathable surface layer 100 does not have hydrostatic waterproofness is compensated, and the multifunctional fabric is endowed with a hydrostatic waterproof effect.

[0065] The knitted bottom layer 300 of this embodiment is a lattice velvet fabric layer having a base 310 and fluff 320, and the base 310 is stacked with the waterproof and breathable middle layer 200. Figure 2 It should be noted that the grid-shaped velvet fabric layer of this embodiment is breathable and soft, and can discharge sweat in time to improve human comfort. The specific operation of the hair-pulling treatment is common knowledge in the art and will not be described in detail here.

[0066] The lattice velvet fabric layer is woven from a plurality of pattern loops, each pattern loop includes 12 coil horizontal paths and 8 coil vertical columns, the 12 coil horizontal paths are defined from top to bottom as the 1st coil horizontal path, the 2nd coil horizontal path, the 3rd coil horizontal path, the 4th coil horizontal path, the 5th coil horizontal path, the 6th coil horizontal path, the 7th coil horizontal path, the 8th coil horizontal path, the 9th coil horizontal path, the 10th coil horizontal path, the 11th coil horizontal path and the 12th coil horizontal path, and the 8 coil vertical columns are defined from left to right as the 1st coil vertical column, the 2nd coil vertical column, the 3rd coil vertical column, the 4th coil vertical column, the 5th coil vertical column, the 6th coil vertical column, the 7th coil vertical column and the 8th coil vertical column.
