Description

Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to an air layer breathable fabric with upper and lower mesh jacquards, a weaving process and a shoe upper. Background Art

[0002] Knitted fabrics are divided into two categories according to the weaving method: weft knitted fabrics and warp knitted fabrics. Weft knitted fabrics are usually made of low-elastic polyester yarn or special-shaped polyester yarn, nylon yarn, cotton yarn, wool yarn, etc., and are woven on various weft knitting machines using plain stitch, altered plain stitch, rib plain stitch, double rib plain stitch, jacquard stitch, terry stitch, etc.

[0003] Knitted fabrics are generally used for shoe uppers, clothing, backpacks and other items. With the progress of society and the gradual improvement of people's living standards, the requirements for the air permeability, comfort, functionality and the like of textile products are getting higher and higher. The existing knitted fabrics used for textile products usually improve the air permeability by making holes through needle turning, and needle turning is often applied to coarse needles. Fine needles cannot perform needle turning due to the finer needle spacing, so their air permeability cannot be improved. Based on this, the present invention provides an air layer breathable fabric with upper and lower mesh jacquards, a weaving process and a shoe upper. Summary of the invention

[0004] The invention provides an air layer breathable fabric with upper and lower mesh jacquards, a weaving process and a shoe upper, which overcome the shortcomings described in the background technology.

[0005] The technical solution adopted by the present invention to solve its technical problem is: The invention discloses an air layer breathable fabric with upper and lower mesh jacquard, comprising a surface layer, a middle layer and a bottom layer. The surface layer and the bottom layer are connected by monofilament or multifilament weaving to form an air layer. The middle layer comprises a plurality of cavities. The surface layer and the bottom layer are both provided with a plurality of semi-permeable holes.

[0006] A preferred technical solution: the upper and lower semi-permeable breathable fabrics are formed by tucking the yarns of the surface layer to the bottom layer, and the yarns of the bottom layer to the surface layer.

[0007] A better technical solution: the similar semi-permeable holes on the surface layer and the bottom layer are formed by the middle monofilament woven surface plus the upper tuck and the middle monofilament woven bottom plus the bottom tuck to form a fully permeable and breathable fabric.

[0009] A better technical solution: the surface yarn is tucked to the bottom layer, and the bottom layer is woven with a single monofilament and tucked to form a fully permeable and breathable fabric from top to bottom.

[0010] A preferred technical solution: a plurality of monofilament tucked semi-permeable holes on the surface layer and the bottom layer form a breathable area.

[0011] A preferred technical solution: a plurality of supporting layers are woven on the surface of the bottom layer, and gaps for air circulation are formed between the supporting layers.

[0012] A preferred technical solution: the monofilament or multifilament is one or more of polyester, nylon, PU and animal or plant fibers.

[0013] A preferred technical solution: the fabric is used for shoe uppers, clothing, furniture or home textile products.

[0014] A shoe upper is an air-layer breathable fabric with upper and lower mesh jacquard patterns, and tucked semi-permeable holes and tucked fully-permeable holes are arranged at any position of the shoe upper.

[0015] A weaving process for an air layer breathable fabric with upper and lower mesh jacquards, the air layer breathable fabric comprising the following weaving processes: Group 1; The first route is to knit monofilament with upper and lower tucks on alternate needles; The second route is to knit the surface layer in jacquard, with the surface layer yarn looped at the holes and the bottom layer tucked; The third route: jacquard weaving of the surface layer; For the fourth route, knit all the needles in a circle to the bottom layer; Next group; In the first route, weave the monofilament with a needle up and down loops, and weave the bottom layer of monofilament in the places with holes; The second route is to knit the surface layer in jacquard, with the surface layer yarn looped at the holes and the bottom layer tucked; The third route: jacquard weaving of the surface layer; The fourth way is to knit with full stitches where there are no holes, knit with tuck stitches where there are holes, or knit with full stitches and loop stitches where there are holes; Among them, the weaving process is to weave at least four routes in one group; when weaving in a group of four routes, one monofilament is run in the middle; when weaving in a group of five routes, two monofilaments are run in the middle.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are: 1.

[0020] Example 1 like Figure 1-Figure 4 As shown, this embodiment provides an air layer breathable fabric with upper and lower mesh jacquards, including a surface layer 1, an intermediate layer, and a bottom layer 3. The surface layer 1 and the bottom layer 3 are connected by monofilament or multifilament weaving to form an air layer 2. The intermediate layer includes a plurality of cavities 21. The surface layer 1 and the bottom layer 3 are both provided with a plurality of semi-permeable holes. Figure 3 FIG. 2 shows a schematic structural diagram of a tuck loop 5 formed on a knitted fabric.

[0021] Furthermore, the yarns of the surface layer 1 are tucked to the bottom layer 3, and the yarns of the bottom layer 3 are tucked to the surface layer 1 to form an upper and lower semi-permeable breathable fabric. The staggered tucks of the surface layer yarn and the bottom layer yarn form a surface-bottom semi-permeable structure, which is beneficial to improving the tightness between different layers of the fabric, while ensuring that the semi-permeable structure provided on the fabric cooperates with the cavity 21 in the middle layer for ventilation. Compared with the fabrics on the market, the breathability is stronger, and the hole structure also gives the fabric a certain style effect.

[0022] Furthermore, the semi-permeable holes on the surface layer 1 and the bottom layer 3 are formed by the middle monofilament woven surface plus the upper tuck loop and the middle monofilament woven bottom plus the bottom tuck loop, forming an upper and lower semi-permeable breathable fabric with at least one needle position deviation. By setting a certain needle position distance deviation between the positions of the semi-permeable holes on the surface layer 1 and the bottom layer 3, although the air permeability is reduced to a certain extent, it can give the fabric a certain warmth retention effect, and the air permeability of the fabric after the reduction can still meet the fabric air permeability requirements.

[0023] Furthermore, a plurality of monofilament tucked semi-permeable holes 4 on the surface layer 1 and the bottom layer 3 form a breathable area, and by concentrating a plurality of tucked semi-permeable holes 4 in a certain area, a certain area of ​​the fabric is more breathable and targeted. For example, when the air layer breathable fabric is used to make clothing, the tucked semi-permeable holes 4 are concentrated in the sweat-prone area on the back of the clothing to form a breathable area.

[0024] Furthermore, a plurality of support layers 31 are woven on the surface of the bottom layer 3, and gaps 32 for air circulation are formed between the support layers 31. Taking the application of clothing as an example, the support layers 31 can form a certain three-dimensional air permeable gap when the bottom layer 3 contacts the skin, so as to enhance the fluidity of air in the gaps 32.

[0025] Furthermore, the monofilament or multifilament is one or more of polyester, nylon, PU and animal and plant fibers. The corresponding yarns can be selected to make the physical properties or functionality of the air layer breathable fabric supported by weaving stronger, and the above materials can be used but are not limited, as long as the corresponding yarns can be used in combination.

[0026] Furthermore, the fabric is used for shoe uppers, clothing, furniture or home textile products.

[0027] Example 2 Reference Figure 5 This embodiment provides an air layer breathable fabric with upper and lower mesh jacquards. The difference in structure between this embodiment and the fabric in embodiment 1 is that there are no semi-permeable holes on the surface, and only the bottom layer 3 has semi-permeable holes formed by weaving the middle monofilament to the bottom. This embodiment is an alternative structure of the air layer breathable fabric in the embodiment. In this embodiment, no semi-permeable holes are set on the surface layer 1, and its warmth retention is further improved.

[0028] Example 3 This embodiment provides an air layer breathable fabric with upper and lower mesh jacquards. The difference in structure between this embodiment and the fabric in embodiment 1 is that: further, the similar semi-permeable holes on the surface layer 1 and the bottom layer 3 are the middle monofilament woven surface plus the upper tuck and the middle monofilament woven bottom plus the bottom tuck to form the upper and lower fully permeable breathable fabric. In this embodiment, the holes on the surface layer 1 and the bottom layer 3 are optimized to be fully permeable holes. Compared with the surface layer 1 and the bottom layer 3 in embodiment 1, which are provided with semi-permeable holes, the air layer breathable fabric formed in this embodiment has better ventilation effect.

[0029] Example 4 The present embodiment provides an air layer breathable fabric with upper and lower mesh jacquards. The structural difference between the fabric in the present embodiment and the fabric in Embodiment 1 is that: further, the yarn of the surface layer 1 is gathered to the bottom layer 3, and at the same time, the bottom layer 3 is woven with a single monofilament and the bottom layer 3 is gathered to form a fully perforated breathable fabric from top to bottom.

[0030] Example 5 This embodiment provides a shoe upper, which is an air layer breathable fabric with upper and lower mesh jacquard as mentioned above, and the tuck semi-permeable holes 4 and the tuck full-permeable holes are arranged at any position of the shoe upper.

[0031] Take the upper and lower mesh jacquard air layer breathable fabric laser cutting to make the upper as an example: after the upper is pasted on the sole to make the finished shoe, the upper can achieve the effect of ventilation and warmth when in use. Hot air flow direction: the hot air generated in the space of the shoe passes through the semi-permeable holes 4 of the bottom layer 3, passes through the cavity 21 in the air layer 2, and then is discharged from the semi-permeable holes 4 of the surface layer 1; because there is a cavity 21 in the air layer 2, the cavity 21 will contain stagnant air, and heat will accumulate in the upper to a certain extent; when the foot is heated after wearing it for a long time, the hot air will naturally flow to the cold air and enter the cavity 21. If the temperature in the cavity 21 is higher than the external environment, it will naturally go out from the surface layer 1, achieving a ventilation effect. Due to the isolation of the surface layer 1 and the temperature difference, the cold air in the external environment will not easily enter the upper through the semi-permeable holes, thereby achieving a warming effect.

[0032] Example 6 Reference Figure 6 , Figure 7 This embodiment provides a weaving process for an air layer breathable fabric with upper and lower mesh jacquards, and the air layer breathable fabric includes the following weaving processes: Group 1; The first route is to knit monofilament with upper and lower tucks on alternate needles; The second route is to knit the surface layer 1 in jacquard, the surface layer 1 yarn is looped at the hole, and the bottom layer 3 is tucked; The third route: jacquard weaving of the surface layer 1; For the fourth route, knit all the stitches in a circle to the bottom layer 3; Next group; First route, weave the monofilament with upper and lower tucks every other needle, and weave the bottom layer of monofilament in the places with holes 3; The second route is to knit the surface layer 1 in jacquard, the surface layer 1 yarn is looped at the hole, and the bottom layer 3 is tucked; The third route: jacquard weaving of the surface layer 1; The fourth way is to knit with full stitches where there are no holes, knit with tuck stitches where there are holes, or knit with full stitches and loop stitches where there are holes; Among them, the weaving process is to weave at least four routes in one group; when weaving in a group of four routes, one monofilament is run in the middle; when weaving in a group of five routes, two monofilaments are run in the middle.

[0033] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
