[0001] The invention relates to the technical field of knitted shoe uppers, in particular to a knitted shoe upper and a knitting method thereof. Background Art
[0002] As people's living standards improve, consumers have higher and higher requirements for wearing comfort. In outdoor sports, daily wear and other scenarios, the air permeability and moisture absorption and perspiration performance of the upper material have become one of the important indicators for evaluating its quality. Although traditional upper materials can meet basic wearing needs, they are prone to cause dampness and stuffiness in extreme weather conditions (such as high temperature and high humidity environments), affecting the wearing experience. To solve this problem, some functional upper materials have appeared on the market, but they generally have problems such as high cost and complex process, making it difficult to promote and use them on a large scale. In order to solve the above problems, this solution was created. Summary of the invention
[0003] The present invention provides a knitted shoe upper and a knitting method thereof, which overcome the shortcomings described in the background technology.
[0004] The technical solution adopted by the present invention to solve its technical problem is:
[0005] A knitted shoe upper, comprising: a surface layer and a bottom layer formed by knitting, the surface layer comprising at least one hydrophilic fiber, the bottom layer comprising at least one water-repellent fiber; the surface layer and the bottom layer are connected by knitting, the bottom layer is provided with a fine pore structure by weaving and at least partially combines and weaves a moisture-absorbing coil, at least partially including partial, full, partial, dispersed and local distribution, etc. Among them, the water-repellent fiber is a fiber treated with a chemical water-repellent agent, after which the surface tension of the fiber is reduced, so that water droplets cannot wet the fiber surface; the hydrophilic fiber refers to a type of fiber material with good water absorption and wettability, which can quickly absorb and retain moisture, and at the same time has good air permeability and comfort; the surface layer can be understood as the outer layer of the knitted shoe upper, and the bottom layer can be understood as the inner layer of the knitted shoe upper.
[0006] Preferably, the moisture-absorbing coils are formed by weaving partial coils of the hydrophilic fibers in the surface layer onto the bottom layer, and the hydrophilic fibers of the surface layer are knitted and connected with the water-repellent fibers of the bottom layer through the moisture-absorbing coils.
[0007] Preferably, the bottom layer further comprises a second hydrophilic fiber, and the moisture-absorbing coil is formed by weaving the second hydrophilic fiber on the bottom layer, wherein the second hydrophilic fiber and the hydrophilic fiber material of the surface layer can be the same or different.
[0008] Preferably, the moisture absorbing coils are all embedded in the bottom layer or knitted and connected to the bottom layer surface. The moisture absorbing coils connect the surface layer and the bottom layer, and can be completely embedded in the bottom layer or connected to the bottom layer surface by knitting. The arrangement density of the moisture absorbing coils is unlimited and can be adjusted according to actual needs to increase or decrease the arrangement density accordingly. The moisture absorbing coils connected to the bottom layer surface can absorb sweat on one side of the bottom layer through fine pore tissue; the moisture absorbing coils embedded in the bottom layer can cooperate with the fine pore tissue to enhance the moisture absorption effect in the bottom layer; the moisture absorbing coils can be combined with the knitting connection of the surface layer and the bottom layer, and completely embedded in the bottom layer to form a corresponding knitted upper structure, thereby fully ensuring the moisture absorption effect of the knitted upper.
[0009] Preferably, the hydrophilic fiber is a microporous hygroscopic yarn. The specific material of the hydrophilic fiber is not limited, nor is the number of hydrophilic fibers included, as long as it is a hydrophilic fiber; the microporous hygroscopic yarn is one of the preferred materials, and hollow fiber yarn, cotton-polyester blended yarn, and CoolMax can be used as a replacement.
[0010] Preferably, the water-repellent fiber is a fluorine-free waterproof yarn. The specific material of the water-repellent fiber is not limited, nor is the number of water-repellent fibers included, as long as it is a water-repellent fiber; the fluorine-free waterproof yarn is one of the preferred materials, and coated waterproof yarn and core-spun yarn can be used as a replacement.
[0011] Preferably, the fine-pore tissue is at least one of a collection of loop holes and stitch holes. The size of the holes formed by the fine-pore tissue on the knitted upper depends on the size of the collection of loop holes and stitch holes. The hole density can also be selected and set according to the position of the upper. For example, after the knitted upper is combined with the sole to form a finished shoe, more dense holes are set in the toe top area. Since the fine-pore tissue is located in the bottom layer close to the foot side of the human body, it can quickly absorb moisture (including moisture and sweat, etc.). After the moisture (including moisture and sweat, etc.) passes through the bottom layer through the pore tissue to reach the moisture absorption coil at the connection between the surface layer and the bottom layer, it is transported to the surface layer through the hydrophilic fibers of the surface layer for diffusion and evaporation.
[0012] Preferably, the combined weaving is formed by one or more of plating, intarsia, tuck and jacquard.
[0013] A knitting method for a knitted shoe upper comprises the following steps:
[0014] Step 1: Use the first hydrophilic fiber to do the surface weaving and assist with the surface weaving bottom tight tuck weaving with regular intervals to form a surface layer; preferably, the hydrophilic fiber is used for at least 1 stitch of surface weaving and assisted with 1 stitch of surface weaving bottom tight tuck, and the above steps are regular weaving; wherein, surface weaving refers to using hydrophilic fibers to weave the surface layer; the purpose of the surface weaving bottom tight tuck is, first, to connect the surface layer and the bottom layer, and second, to form a small hole through the tuck so that moisture can pass through the small hole to conduct to the moisture absorption layer.
[0015] Step 2: Use water-repellent fiber to make full-needle bottom weaving; preferably, steps 1 and 2 are performed simultaneously, and the hydrophilic fiber is unilaterally connected to the water-repellent fiber through a tuck loop to form pores;

[0017] Step 4: weaving a moisture-absorbing coil on the bottom layer formed in step 2; preferably, step 4 is weaving the moisture-absorbing coil, and the bottom needle positions where the water-repellent fibers should be woven are woven with hydrophilic fibers, so the water-repellent fibers can only be woven with the corresponding surface needle positions to form surface weaving;
[0018] Step 5: Repeat the above steps until a complete knitted upper is formed.
[0019] Preferably, the moisture-absorbing coil of step four is formed by weaving the first hydrophilic fiber of step one, and connecting the surface layer and the bottom layer.
[0020] Preferably, the surface layer and the bottom layer are connected by knitting, and the moisture-absorbing coils in step four are formed by weaving the second hydrophilic fiber on the bottom layer.
[0021] Preferably, after weaving is completed, the knitted upper is subjected to a high temperature treatment of 85°C-180°C.
[0022] By adopting the above technical solution, the beneficial effects of the present invention are:
[0023] 1. The present invention adopts the principle of unidirectional moisture conduction. The sweat generated by the feet can be quickly absorbed by the fine and dense circles of holes on the bottom layer and the micro-porous moisture conduction coils, and then unidirectionally guided to the upper through the moisture conduction coils; and quickly diffuse to the entire upper, increasing the evaporation area for quick drying, effectively solving the problem of moisture accumulation in the shoe.

[0033] Example 1
[0034] like Figure 1 , Figure 3 As shown, this embodiment provides a knitted upper, including: a surface layer 1 and a bottom layer 2 formed by knitting, the surface layer 1 includes at least one hydrophilic fiber, and the bottom layer 2 includes at least one water-repellent fiber; the surface layer 1 and the bottom layer 2 are connected by knitting, and the bottom layer 2 is provided with a fine pore structure 21 by weaving and a moisture-absorbing coil 11 is partially combined and woven. The fine pores woven by the water-repellent fiber combined with the moisture-absorbing coil 11 can quickly guide moisture out and diffuse it to the surface layer 1, so that the bottom end of the bottom layer 2 will not stick to the skin due to moisture. The hydrophilic fiber of the surface layer 1 can quickly guide moisture (including moisture and sweat, etc.) out and diffuse it to the upper, increase the evaporation area, and achieve a quick-drying effect. Among them, the bottom layer 2 is combined with a moisture-absorbing coil 11, which specifically refers to a moisture-absorbing coil structure woven on the bottom layer 2; the fine pores are specifically a small and dense pore structure formed by the fine pore structure 21 on the bottom layer. The surface layer 1 contains at least one hydrophilic fiber, that is, it can contain one, or two, or even more different hydrophilic fibers, as long as the corresponding hydrophilic fibers can be used by the weaving equipment to participate in weaving, and there is no limit on the specific type of hydrophilic fibers constituting the surface layer 1, as long as the hydrophilic fibers have the functions of moisture absorption and moisture conduction. The bottom layer 2 contains at least one water-repellent fiber, that is, it can contain one, or two, or even more different water-repellent fibers, as long as the corresponding water-repellent fibers can be used by the weaving equipment to participate in weaving, and there is no limit on the specific type of water-repellent fibers constituting the bottom layer 2.
[0035] The upper layer 1 and the bottom layer 2 in the knitted upper are connected by knitting. The knitted connection here means that the upper layer 1 and the bottom layer 2 are knitted together through a moisture-absorbing coil 11. Specifically, the overall structure of the upper is directly woven through a computer flat knitting machine or a circular knitting machine without sewing. This is an one-piece knitted connection; or yarns of different colors, materials or functions are woven together through jacquard technology or intarsia technology to achieve complex patterns and functional zoning (breathable area, support area).
[0036] A fine-pore tissue 21 is provided in the bottom layer 2. Since the fine-pore tissue 21 is located at the bottom layer 2 on the side of the human body close to the instep, it can quickly absorb moisture (including moisture and sweat, etc.). After the moisture (including moisture and sweat, etc.) passes through the bottom layer 3 through the fine-pore tissue 21 to reach the moisture absorption coil at the connection between the surface layer 1 and the bottom layer 2, it is transported to the upper through the hydrophilic fibers of the surface layer 1 for diffusion and evaporation; the fine-pore tissue 21 and the moisture absorption coil 11 can be distributed regularly or irregularly, and the moisture absorption coil 21 can also be arranged inside the fine-pore tissue 21, and the positional relationship between the fine-pore tissue 21 and the moisture absorption coil 11 is not limited.
[0037] The moisture absorbing coil 11 is at least partially combined and woven on the bottom layer 2, and at least partially includes partial, full, partial, dispersed and local distribution, etc. It can be woven on the entire bottom layer 2, or it can be woven in a local area of the bottom layer 2. The combined weaving can be a combination of several of the following methods: 1. Partition weaving, the upper is divided into different areas, and each area uses a different weaving density or pattern; application: high support areas (such as ankles) use tight weaving, and breathable areas (such as insteps) use loose weaving, and then cooperate with the moisture absorbing coil 11; at this time, the upper takes into account support, breathability and moisture absorption. 2. Gradual weaving, the weaving density of the moisture absorbing coil 11 gradually changes from one part of the upper to another; application: the weaving density gradually increases from the forefoot to the heel to provide progressive support; it can enhance the dynamic adaptability of the upper. 3. Hollow weaving, hollow or mesh weaving is used in specific areas of the upper (such as the instep or side) and combined with the moisture absorbing coil 11 to improve the breathability of the upper and reduce the weight of the shoe body.
[0038] The moisture absorbing coil 11 refers to a coil structure with moisture absorbing function woven by a knitting process. This type of coil is usually made of hydrophilic fibers with strong hygroscopicity or special weaving technology, which can quickly absorb and diffuse moisture to keep the fabric dry and comfortable. Moisture absorbing coil 11: uses hydrophilic fibers as raw materials, and enhances moisture absorption and perspiration performance through special knitting structures (such as mesh structures, honeycomb structures, etc.). The area of the woven connection between the moisture absorbing coil 11 and the bottom layer 2 usually depends on the weaving program set by the knitting machine. The moisture absorbing coil 11 can be completely embedded in the bottom layer 2, or the moisture absorbing coil 11 can be connected to the surface of the bottom layer 2.
[0039] Furthermore, the moisture-absorbing coil 11 is formed by weaving partial coils of the hydrophilic fiber in the surface layer 1 on the bottom layer 2 .
[0040] Furthermore, the moisture-absorbing coil 11 connects the surface layer 1 and the bottom layer 2 by knitting. Here, the moisture-absorbing coil 11 and the surface layer 1 use the same hydrophilic fiber and only serves to connect the surface layer 1 and the bottom layer 2.
[0041] Furthermore, the hydrophilic fiber is a microporous hygroscopic yarn, which is often called hygroscopic yarn in the industry. Microporous hygroscopic yarn refers to hygroscopic yarn with tiny holes. These tiny holes can efficiently assist in moisture absorption. There is no limit on the specific material of the hydrophilic fiber, nor on the number of hydrophilic fibers included, as long as it is hydrophilic fiber. Microporous hygroscopic yarn is one of the preferred materials, and hollow fiber yarn, cotton-polyester blended yarn, and CoolMax can be used as replacements.
[0042] Furthermore, the water-repellent fiber is a fluorine-free waterproof yarn. There is no limitation on the specific material of the water-repellent fiber, nor on the number of water-repellent fibers included, as long as it is a water-repellent fiber. The fluorine-free waterproof yarn is one of the preferred materials, and coated waterproof yarn or core-spun yarn can be used as a replacement.
[0043] Furthermore, the fine-pore tissue 21 is at least one of a collection of loop holes and turned needle holes. Either a collection of loop holes or turned needle holes can be set, or both collection of loop holes and turned needle holes can be set. The water-repellent fibers of the bottom layer are collected by collection or turning to the surface layer to form pores; moisture (including moisture and sweat, etc.) passes through the bottom layer 2 through the fine-pore tissue 21, is absorbed by the moisture-absorbing coils 11 woven at the connection between the surface layer 1 and the bottom layer 2, and is transported to the hydrophilic fibers of the surface layer 1, and is conducted out to the upper for diffusion and evaporation.
[0044] Furthermore, the combined weaving is formed by one or more of plating, intarsia, tucking and jacquard.
[0045] Furthermore, a plurality of ventilation holes 3 are provided on the surface layer 1, and a moisture conduction area 4 can be provided partially or entirely on the knitted upper.
[0046] Example 2
[0047] like Figure 2a , b, Figure 3 As shown, this embodiment provides a knitted upper, comprising: a surface layer 1 and a bottom layer 2 formed by knitting, the surface layer 1 comprising at least one hydrophilic fiber, and the bottom layer 2 comprising at least one water-repellent fiber; the surface layer 1 and the bottom layer 2 are connected by knitting, and the bottom layer 2 is provided with a fine pore structure 21 by weaving and partially combined with a woven moisture-absorbing coil 11. The fine pore structure 21 woven by the water-repellent fiber combined with the moisture-absorbing coil 11 can quickly guide moisture out and diffuse it to the surface layer 1, so that the bottom end of the bottom layer 2 will not stick to the skin due to moisture. The hydrophilic fiber of the surface layer 1 can quickly guide moisture (including moisture and sweat, etc.) out and diffuse it to the upper, increase the evaporation area, and achieve a quick-drying effect.
[0048] Furthermore, the moisture-absorbing coils 11 are all embedded and woven into the bottom layer 2, and the moisture-absorbing coils 11 and the surface layer 1 use the same hydrophilic fiber; the moisture-absorbing coils 11 knitted to connect the surface layer 1 and the bottom layer 2 and the moisture-absorbing coils 11 knitted and embedded into the bottom layer 2 have no restrictions on the weaving density, and can be increased according to actual needs to arrange them tightly or sparsely. The moisture-absorbing coils 11 can cooperate with the fine pore tissue 21 to absorb and guide the sweat on one side of the bottom layer 2, thereby enhancing the moisture absorption and moisture conduction effect.
[0049] Example 3
[0050] The difference between this embodiment and embodiment 1-2 is that the moisture-absorbing coil 11 here is woven with a second hydrophilic fiber material different from the hydrophilic fiber of the surface layer 1. The moisture-absorbing coil 11 woven with the second hydrophilic fiber is combined with the fine pore structure 21 to conduct moisture (including moisture and sweat, etc.) to the hydrophilic fibers in the surface layer 1 for diffusion and increase the evaporation area.
[0051] Example 4
[0052] like Figure 4 As shown, this embodiment provides a knitting method for a knitted shoe upper, comprising the following steps:
[0053] Step 1: Use the first hydrophilic fiber to do the surface weaving and assist with the surface weaving bottom tight tuck weaving with regular intervals to form a surface layer; preferably, the hydrophilic fiber is used for at least 1 stitch of surface weaving and assisted with 1 stitch of surface weaving bottom tight tuck, and the above steps are regular weaving; wherein, surface weaving refers to using hydrophilic fibers to weave the surface layer; the purpose of the surface weaving bottom tight tuck is, first, to connect the surface layer and the bottom layer, and second, to form a small hole through the tuck so that moisture can pass through the small hole to conduct to the moisture absorption layer.
[0054] Step 2: Use water-repellent fiber to make full-needle bottom weaving; preferably, steps 1 and 2 are performed simultaneously, and the hydrophilic fiber is unilaterally connected to the water-repellent fiber through a tuck loop to form pores;
[0055] Step 3: Repeat the surface weaving with hydrophilic fibers while assisting the surface weaving with regularly spaced bottom tight tuck weaving, and the weaving position is offset by at least 1 stitch distance compared with the weaving position in step 1; preferably, step 3 is the repeated weaving of steps 1 and 2;
[0056] Step 4: weaving a moisture-absorbing coil on the bottom layer formed in step 2; preferably, step 4 is weaving the moisture-absorbing coil, and the bottom needle positions where the water-repellent fibers should be woven are woven with hydrophilic fibers, so the water-repellent fibers can only be woven with the corresponding surface needle positions to form surface weaving;
[0057] Step 5: Repeat the above steps until a complete knitted upper is formed.
[0058] Furthermore, the moisture-absorbing coil of step four is formed by weaving the first hydrophilic fiber of step one, and connecting the surface layer and the bottom layer.
[0059] Further, the surface layer and the bottom layer are connected by knitting, and the moisture-absorbing coil of step four is formed by weaving the second hydrophilic fiber on the bottom layer.
[0060] Furthermore, after the knitting is completed, the knitted upper is subjected to a high temperature treatment of 85°C-180°C.
[0061] For example, the hydrophilic fiber is a microporous moisture-absorbing yarn and is woven with two needles, and the water-repellent fiber is a fluorine-free waterproof yarn.
[0062] The specific weaving method is:
[0063] The first knitting row is a 2-needle surface knitting with micro-porous moisture-absorbing yarn and a 1-needle surface knitting with a tight tuck at the bottom;
[0064] The second weaving row is made of fluorine-free waterproof yarn with full stitch bottom weaving;
[0065] The third knitting row is a 2-needle surface knitting and 1-needle surface knitting bottom tight tuck knitting with microporous moisture-absorbing yarn. Compared with the first knitting row, the position is offset by 1 needle distance;
[0066] The 4th knitting row is full-stitch bottom knitting with fluorine-free waterproof yarn;
[0067] The fifth knitting row is a 2-needle surface knitting and 1-needle surface knitting bottom tight tuck knitting with micro-porous moisture-absorbing yarn. Compared with the third knitting row, it is offset by 1 needle position and partially knitted as the bottom.
[0068] The 6th row is made of fluorine-free waterproof yarn as the bottom weave, and the bottom stitch position of the 5th row is used for the top weave;
[0069] The 7th knitting row is a 2-needle surface knitting and 1-needle surface knitting bottom tight tuck knitting with micro-porous moisture-absorbing yarn. Compared with the 5th knitting row, the position is offset by 1 needle distance;
[0070] The 8th weaving row is full-stitch bottom weaving with fluorine-free waterproof yarn;
[0071] The 9th knitting row is a 2-needle surface knitting and 1-needle surface knitting bottom tight tuck knitting with micro-porous moisture-absorbing yarn. Compared with the 7th knitting row, the position is offset by 1 needle distance;
[0072] The 10th knitting row is made of fluorine-free waterproof yarn with full stitch bottom knitting;
[0073] The 11th knitting row is a 2-needle surface knitting and 1-needle surface knitting bottom tight tuck knitting with microporous moisture-absorbing yarn. Compared with the 9th knitting row, it is offset by 1 needle position and partially knitted as the bottom.
[0074] The 12th row is made of fluorine-free waterproof yarn as the base weave, and the bottom loop needle position of the 11th row is used for the surface weave.
[0075] The 1st to 12th rows are the smallest cycle unit, and the 13th to 20th rows are repeated weavings of the 1st to 8th rows.
[0076] The purpose of weaving the surface layer 1 with fluorine-free waterproof yarn is to weave moisture-conducting loops with hydrophobic function in the waterproof layer, so that moisture can be smoothly conducted to the upper layer 1 and quickly diffused in the surface layer 1, thereby increasing the evaporation area and achieving a quick-drying effect.
[0077] After the fabric is woven, it needs to be treated with high temperature. For fabrics that do not use hot melt, the high temperature treatment is to allow the fabric to fully shrink when heated to achieve the appropriate fabric effect; for fabrics that use hot melt, it needs to be treated with high temperature to melt the hot melt and bond it inside the fabric to achieve the appropriate fabric effect. The high temperature treatment temperature of the hot melt is about 85℃-160℃.

[0079] The difference between this embodiment and embodiment 4 is that the hydrophilic fiber is knitted with one needle surface and assisted by one needle surface knitting with a tight hook at the bottom.
[0080] For example, the hydrophilic fiber is a microporous moisture-absorbing yarn, and the water-repellent fiber is a fluorine-free waterproof yarn.
[0081] The specific weaving method is:

[0086] The fifth knitting row is a 1-needle surface knitting and 1-needle surface knitting bottom tight tuck knitting with micro-porous moisture-absorbing yarn. Compared with the third knitting row, the position of one needle is offset and the bottom knitting is partially done;
[0087] The 6th row is made of fluorine-free waterproof yarn as the bottom weave, and the bottom stitch position of the 5th row is used for the top weave;

[0089] The 8th weaving row is full-stitch bottom weaving with fluorine-free waterproof yarn;
[0090] The 9th knitting row is a 1-needle surface knitting and 1-needle surface knitting bottom tight tuck knitting with micro-porous moisture-absorbing yarn. Compared with the 7th knitting row, the position is offset by 1 needle distance;

[0093] The 12th row is made of fluorine-free waterproof yarn as the base weave, and the bottom loop needle position of the 11th row is used for the surface weave.
[0094] The 1st to 12th rows are the smallest cycle unit, and the 13th to 20th rows are repeated weavings of the 1st to 8th rows.
