Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of knitted uppers, in particular to a knitted upper. BACKGROUND

[0002] With the improvement of people's living standards, consumers' requirements for wearing comfort are also getting higher and higher. In many scenes such as outdoor sports and daily wear, the air permeability and moisture absorption and perspiration performance of the upper material become one of the important indicators for evaluating its quality. Although the traditional upper material can meet the basic wearing needs, it is easy to cause the feet to be damp and hot in extreme weather conditions (such as high temperature and high humidity environment), which affects the wearing experience. In order to solve this problem, some functional upper materials appear on the market, but there are problems such as high cost and complex process, which are difficult to promote on a large scale. In order to solve the above problems, the present scheme is produced. SUMMARY

[0003] The utility model provides a kind of knitted upper, it overcomes the deficiency described in background art.

[0004] The utility model solves the technical problem and the technical scheme adopted by the utility model is as follows:

[0005] A knitted upper, comprising: a face layer and a bottom layer formed by knitting, the face layer comprising at least one hydrophilic fiber, and the bottom layer comprising at least one water-repellent fiber; the face layer and the bottom layer are connected by knitting, and the bottom layer is provided with fine pore structure by knitting and at least partially combined with moisture-absorbing loops, which at least partially include local, all, partial, dispersed distribution, etc. The water-repellent fiber is a fiber treated with a chemical water-repellent agent, which reduces the surface tension of the fiber after treatment, so that water droplets cannot wet the surface of the fiber. The hydrophilic fiber refers to a type of fiber material with good water absorption and wetting properties. This type of fiber can quickly absorb and retain water, while maintaining good air permeability and comfort. The face layer can be understood as the outer layer of the knitted upper, and the bottom layer can be understood as the inner layer of the knitted upper.

[0006] Preferably, the moisture-absorbing loops are formed by knitting part of the loops of the hydrophilic fiber in the face layer on the bottom layer, and the hydrophilic fiber in the face layer is connected to the water-repellent fiber in the bottom layer by the moisture-absorbing loops.

[0007] Preferably, the bottom layer further comprises a second hydrophilic fiber, and the moisture-absorbing loops are combined and knitted on the bottom layer by the second hydrophilic fiber. The second hydrophilic fiber and the hydrophilic fiber material in the face layer can be the same or different.

[0008] Preferably, the moisture-absorbing coil is entirely embedded in the bottom layer or knitted to the surface of the bottom layer. The moisture-absorbing coil connects the surface layer and the bottom layer, can be entirely embedded in the bottom layer, or can be knitted to the surface of the bottom layer. The arrangement density of the moisture-absorbing coil is not limited and can be adjusted according to actual needs, and the arrangement density can be increased or decreased accordingly. The moisture-absorbing coil connected to the surface of the bottom layer can absorb moisture through the fine hole organization on one side of the bottom layer; the moisture-absorbing coil embedded in the bottom layer can cooperate with the fine hole organization to improve the moisture-absorbing effect in the bottom layer; the moisture-absorbing coil can form a corresponding knitted vamp structure by being knitted to the surface layer and the bottom layer or being entirely embedded in the bottom layer, thereby fully ensuring the moisture-absorbing effect of the knitted vamp.

[0009] Preferably, the hydrophilic fiber is a microporous moisture-absorbing yarn. The specific material of the hydrophilic fiber is not limited, and the hydrophilic fiber is not limited to containing several kinds of hydrophilic fiber. The microporous moisture-absorbing yarn is one of the preferred materials, and hollow fiber yarn, cotton-polyester blended yarn, or 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, and the water-repellent fiber is not limited to containing several kinds of 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.

[0011] Preferably, the fine hole organization is at least one of tuck hole and purl hole. The size of the hole formed by the fine hole organization on the knitted vamp depends on the size of the tuck hole and the purl hole, and the hole density can also be selected and set according to the position of the vamp. For example, after the knitted vamp is combined with the sole to form a finished shoe, more dense holes can be set in the top area of the toe. Since the fine hole organization is located on the bottom layer close to the foot surface of the human body, it can quickly absorb moisture (including humidity and sweat, etc.). After the moisture (including humidity and sweat, etc.) passes through the bottom layer to the moisture-absorbing coil at the connection between the surface layer and the bottom layer through the hole organization, it is sent to the surface layer for diffusion and evaporation through the hydrophilic fiber of the surface layer.

[0012] Preferably, the combined knitting is one or more of plating, intarsia, tucking, and jacquard.

[0013] A knitting method of a knitted vamp, comprising the following steps:

[0014] Step one: using a first hydrophilic fiber to knit the surface while assisting the regularly spaced surface knitting bottom tight loop stitch to knit, so as to form a surface layer; preferably, the hydrophilic fiber knits the surface for at least 1 needle, while assisting the surface knitting bottom tight loop stitch for 1 needle. The above steps are regular knitting. The surface knitting refers to using the hydrophilic fiber to knit the surface layer. The purpose of the surface knitting bottom tight loop stitch is to connect the surface layer and the bottom layer, and to form a small hole through the loop stitch to enable the moisture to be conducted to the moisture-absorbing layer.

[0015] Step 2: Use water-repellent fibers to knit the entire bottom of the needle; preferably, steps 1 and 2 are performed simultaneously, with hydrophilic fibers forming pores by connecting the water-repellent fibers through loops on one side.

[0016] Step 3: Repeat the surface knitting with hydrophilic fibers while supplementing with regularly spaced surface knitting and bottom tight hanging stitch knitting. Compared with the knitting position in Step 1, the knitting position is offset by at least 1 stitch. Preferably, Step 3 is a repetition of Step 1 and Step 2.

[0017] Step 4: Weave moisture-absorbing coils on the bottom layer formed in Step 2; preferably, Step 4 is the weaving of moisture-absorbing coils. The bottom needle positions, which should be woven with water-repellent fibers, are instead woven with hydrophilic fibers. Therefore, the water-repellent fibers can only be woven into the corresponding top needle positions, forming a surface weave.

[0018] Step 5: Repeat the above steps until a complete knitted shoe upper is formed.

[0019] Preferably, the moisture-absorbing coil in step four is formed by weaving the first type of hydrophilic fiber in step one and connecting the surface layer and the bottom layer.

[0020] Preferably, the top layer and the bottom layer are connected by knitting, and the moisture-absorbing coil in step four is formed by weaving a second type of hydrophilic fiber onto the bottom layer.

[0021] Preferably, after the knitting is completed, the knitted shoe upper is subjected to a high-temperature treatment of 85℃-180℃.

[0022] By adopting the above technical solution, the beneficial effects of this utility model are:

[0023] 1. This utility model adopts the principle of one-way moisture wicking. Sweat produced by the feet can be quickly absorbed through the fine and dense pores on the bottom layer and the micro-porous moisture wicking coil, and then unidirectionally guided to the shoe surface through the moisture wicking coil; and quickly diffused to the entire shoe surface, increasing the evaporation area and drying quickly, effectively solving the problem of moisture accumulation inside the shoe.

[0024] 2. The knitted upper in this invention effectively keeps feet dry, reducing stuffiness and discomfort caused by dampness, ensuring comfort for users whether walking or exercising. The knitted upper also reduces the environment for bacterial growth inside the shoe, lowering the risk of fungal infections and other foot diseases, thus promoting foot health.

[0025] 3. The knitted shoe upper of this invention has a simple manufacturing process, low cost, and is easy to mass-produce; it is suitable for various types of shoes, such as sports shoes and casual shoes, and has broad application prospects. Attached Figure Description

[0033] Example 1

[0034] like Figure 1 , Figure 3 As shown, this embodiment provides a knitted shoe upper, including: a surface layer 1 and a bottom layer 2 formed by knitting. The surface layer 1 contains at least one hydrophilic fiber, and the bottom layer 2 contains at least one water-repellent fiber. The surface layer 1 and the bottom layer 2 are connected by knitting. The bottom layer 2 is woven with a fine porous structure 21 and partially combined with moisture-absorbing coils 11. The water-repellent fibers with fine pores combined with the moisture-absorbing coils 11 can quickly conduct moisture and diffuse it to the surface layer 1, preventing the bottom of the bottom layer 2 from sticking to the skin due to moisture. The hydrophilic fibers of the surface layer 1 can quickly conduct moisture (including moisture and sweat) and diffuse it to the shoe upper, increasing the evaporation area and achieving a quick-drying effect. Specifically, the bottom layer 2 is combined with moisture-absorbing coils 11, meaning that a moisture-absorbing coil structure is woven into the bottom layer 2; the fine pores specifically refer to the small and dense pore structure formed by the fine porous structure 21 on the bottom layer. The surface layer 1 contains at least one hydrophilic fiber, which can contain one, two, or even more different hydrophilic fibers, as long as the corresponding hydrophilic fibers can be used by weaving equipment to participate in weaving. There is no restriction on the specific type of hydrophilic fiber that makes up the surface layer 1, as long as the hydrophilic fiber has the function of absorbing and wicking moisture. The bottom layer 2 contains at least one water-repellent fiber, which can contain one, two, or even more different water-repellent fibers, as long as the corresponding water-repellent fibers can be used by weaving equipment to participate in weaving. There is no restriction on the specific type of water-repellent fiber that makes up the bottom layer 2.

[0035] In the knitted shoe upper, the upper layer 1 and the bottom layer 2 are connected by knitting. Here, knitting connection means that the upper layer 1 and the bottom layer 2 are knitted together by moisture-absorbing loops 11. Specifically, the overall structure of the shoe upper is directly knitted by a computer flat knitting machine or circular knitting machine without sewing. This is a one-piece knitted connection. Alternatively, different colors, materials or functions of yarns can be woven together by jacquard or intarsia techniques to achieve complex patterns and functional zones (breathable zone, support zone).

[0036] The bottom layer 2 is provided with a fine porous structure 21. Since the fine porous structure 21 is located on the bottom layer 2 near the foot, it can quickly absorb moisture (including moisture and sweat). The moisture (including moisture and sweat) passes through the fine porous structure 21 through the bottom layer 3 to the moisture-absorbing coil at the junction of the top layer 1 and the bottom layer 2. Then, it is distributed to the shoe surface for diffusion and evaporation through the hydrophilic fibers of the top layer 1. The fine porous structure 21 and the moisture-absorbing coil 11 can be distributed regularly or irregularly. The moisture-absorbing coil 21 can also be set inside the fine porous structure 21. The positional relationship between the fine porous structure 21 and the moisture-absorbing coil 11 is not limited.

[0037] The moisture-wicking coils 11 are at least partially woven into the bottom layer 2, including partial, complete, partial, and dispersed partial distributions. They can be woven throughout the entire bottom layer 2 or into specific areas of the bottom layer 2. The combined weaving can be a combination of several of the following: 1. Zoned weaving: Dividing the upper into different zones, each zone using a different weaving density or pattern; Application: Using tight weaving in high-support areas (such as the ankle) and loose weaving in breathable areas (such as the instep), combined with the moisture-wicking coils 11; In this case, the upper balances support, breathability, and moisture wicking. 2. Gradient weaving: The weaving density of the moisture-wicking coils 11 gradually changes from one part of the upper to another; Application: Gradually increasing the weaving density from the forefoot to the heel provides progressive support; This enhances the dynamic adaptability of the upper. 3. Openwork weaving: Using openwork or mesh weaving in specific areas of the upper (such as the instep or sides) and combining it with the moisture-wicking coils 11 to improve the breathability of the upper and reduce the weight of the shoe.

[0038] Moisture-wicking coil 11 refers to a coil structure with moisture-wicking function woven through a knitting process. This type of coil is typically made of highly absorbent hydrophilic fibers or special knitting techniques, enabling it to quickly absorb and diffuse moisture, keeping the fabric dry and comfortable. Moisture-wicking coil 11: Uses hydrophilic fibers as raw material, and enhances moisture absorption and wicking performance through special knitting structures (such as mesh structures, honeycomb structures, etc.). The area where the moisture-wicking coil 11 is knitted and connected to the bottom layer 2 usually depends on the knitting program set on the knitting machine; either the moisture-wicking coil 11 can be completely embedded in the bottom layer 2, or it can be connected to the surface of the bottom layer 2.

[0039] Furthermore, the moisture-absorbing coil 11 is formed by partially coiling the hydrophilic fibers in the surface layer 1 onto the bottom layer 2.

[0040] Furthermore, the moisture-absorbing coil 11 connects the surface layer 1 and the bottom layer 2 through knitting. Here, the moisture-absorbing coil 11 and the surface layer 1 use the same hydrophilic fiber, and the coil only serves to connect the surface layer 1 and the bottom layer 2.

[0041] Furthermore, the hydrophilic fiber is a microporous moisture-absorbing yarn, often referred to as moisture-absorbing yarn in the industry. Microporous moisture-absorbing yarn refers to moisture-absorbing yarn with tiny pores. These tiny pores can efficiently assist in moisture absorption. There are no restrictions on the specific material of the hydrophilic fiber, nor on the number of hydrophilic fibers included. As long as it is a hydrophilic fiber, it is acceptable. Microporous moisture-absorbing yarn is one of the preferred materials. Hollow fiber yarn, cotton-polyester blended yarn, and CoolMax can be used as alternatives.

[0042] Furthermore, the water-repellent fiber is a fluorine-free waterproof yarn. There are no restrictions 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, it is acceptable. Fluorine-free waterproof yarn is one of the preferred materials, and coated waterproof yarn or core-spun yarn can be used as alternatives.

[0043] Furthermore, the fine porous structure 21 is at least one of tufted holes and flip-hole holes. It can be provided with tufted holes or flip-hole holes, or both tufted holes and flip-hole holes. The water-repellent fibers of the bottom layer form pores through tufting or flipping to the surface layer. Moisture (including moisture and sweat) passes through the bottom layer 2 through the fine porous structure 21 and is absorbed and transported to the hydrophilic fibers of the surface layer 1 by the moisture-absorbing coils 11 woven at the junction of the surface layer 1 and the bottom layer 2, and then carried out to the shoe surface for diffusion and evaporation.

[0044] Furthermore, the combination weaving is formed by one or more of the following methods: adding yarn, inlay, tufting, and jacquard.

[0045] Furthermore, several ventilation holes 3 are provided on the surface layer 1, and moisture-wicking zones 4 can be set in parts or the whole of the knitted shoe upper.

[0046] Example 2

[0047] like Figure 2a b Figure 3 As shown, this embodiment provides a knitted shoe upper, comprising: a surface layer 1 and a bottom layer 2 formed by knitting. The surface layer 1 contains at least one hydrophilic fiber, and the bottom layer 2 contains at least one water-repellent fiber. The surface layer 1 and the bottom layer 2 are connected by knitting. The bottom layer 2 is woven with a fine porous structure 21 and partially combined with moisture-absorbing coils 11. The water-repellent fiber weave of the fine porous structure 21 combined with the moisture-absorbing coils 11 can quickly wick away moisture and diffuse it to the surface layer 1, preventing the bottom of the bottom layer 2 from sticking to the skin due to moisture. The hydrophilic fibers of the surface layer 1 can quickly wick away moisture (including dampness and sweat) and diffuse it to the shoe upper, increasing the evaporation area and achieving a quick-drying effect.

[0048] Furthermore, all moisture-absorbing coils 11 are embedded in the bottom layer 2, and the moisture-absorbing coils 11 here use the same hydrophilic fiber as the top layer 1. The density of the moisture-absorbing coils 11 that connect the top layer 1 and the bottom layer 2 through knitting and the moisture-absorbing coils 11 embedded in the bottom layer 2 is unlimited, and the density can be increased to make them dense or sparse according to actual needs. The moisture-absorbing coils 11 can work with the fine porous structure 21 to absorb and wick away sweat from one side of the bottom layer 2, enhancing the moisture absorption and wicking effect.

[0049] Example 3

[0050] The difference between this embodiment and embodiments 1-2 is that the moisture-absorbing coil 11 here is woven with a second hydrophilic fiber material that is different from the hydrophilic fiber of the surface layer 1. The moisture-absorbing coil 11 woven with the second hydrophilic fiber, combined with the fine porous structure 21, guides moisture (including moisture and sweat) to the hydrophilic fiber in the surface layer 1 for diffusion and increases the evaporation area.

[0051] Example 4

[0052] like Figure 4 As shown, this embodiment provides a knitting method for shoe uppers, including the following steps:

[0053] Step 1: Use the first type of hydrophilic fiber to make the surface knit, while simultaneously assisting with regularly spaced surface knit bottom tight hanging mesh knit to form the surface layer; preferably, the hydrophilic fiber is used to make at least 1 stitch of surface knit, while simultaneously assisting with 1 stitch of surface knit bottom tight hanging mesh. The above steps are regular knitting; where surface knit refers to using hydrophilic fiber to knit the surface layer; the purpose of surface knit bottom tight hanging mesh is twofold: first, to connect the surface layer and the bottom layer, and second, to form a small hole through the hanging mesh, allowing moisture to pass through the small hole to be conducted to the moisture-absorbing layer.

[0054] Step 2: Use water-repellent fibers to knit the entire bottom of the needle; preferably, steps 1 and 2 are performed simultaneously, with hydrophilic fibers forming pores by connecting the water-repellent fibers through loops on one side.

[0055] Step 3: Repeat the surface knitting with hydrophilic fibers while supplementing with regularly spaced surface knitting and bottom tight hanging stitch knitting. Compared with the knitting position in Step 1, the knitting position is offset by at least 1 stitch. Preferably, Step 3 is a repetition of Step 1 and Step 2.

[0056] Step 4: Weave moisture-absorbing coils on the bottom layer formed in Step 2; preferably, Step 4 is the weaving of moisture-absorbing coils. The bottom needle positions, which should be woven with water-repellent fibers, are instead woven with hydrophilic fibers. Therefore, the water-repellent fibers can only be woven into the corresponding top needle positions, forming a surface weave.

[0057] Step 5: Repeat the above steps until a complete knitted shoe upper is formed.

[0058] Furthermore, the moisture-absorbing coil in step four is formed by weaving the first type of hydrophilic fiber from step one, and is connected to the top and bottom layers.

[0059] Furthermore, the top and bottom layers are connected by knitting, and the moisture-absorbing coils in step four are formed by weaving a second type of hydrophilic fiber onto the bottom layer.

[0060] Furthermore, after the knitting is completed, the knitted shoe upper is subjected to a high-temperature treatment at 85℃-180℃.

[0061] Taking a microporous, moisture-absorbing yarn made of hydrophilic fiber and knitted with a two-needle surface, and a fluorine-free, waterproof yarn made of water-repellent fiber as an example...

[0062] The specific weaving method is as follows:

[0063] The first row is a 2-needle face knitting and a 1-needle face knitting with a tight bottom and hanging loops using microporous moisture-absorbing yarn;

[0064] The second row is knitted with a full needle base using fluorine-free waterproof yarn;

[0065] The third row is a 2-needle face knitting and 1-needle face knitting with a tight bottom and hanging loop using microporous moisture-wicking yarn. Compared with the first row, the position is shifted by 1 stitch.

[0066] The fourth row is knitted with a full needle base using fluorine-free waterproof yarn;

[0067] The fifth row is a 2-needle face knitting and 1-needle face knitting with a tight bottom and hanging loop, made with microporous moisture-wicking yarn. Compared with the third row, it is shifted by 1 needle position and partially knitted at the bottom.

[0068] The 6th row is knitted with fluorine-free waterproof yarn as the base, and the top is knitted at the bottom loop stitches of the 5th row.

[0069] Row 7 is a 2-needle face knitting and 1-needle face knitting with a tight bottom and hanging loop using microporous moisture-wicking yarn. Compared with row 5, the position is shifted by 1 stitch.

[0070] The 8th row is knitted with a full needle base using fluorine-free waterproof yarn;

[0071] Row 9 is a 2-needle face knitting and 1-needle face knitting with a tight bottom and hanging loop using microporous moisture-wicking yarn. Compared with row 7, the position is shifted by 1 stitch.

[0072] The 10th row is knitted with a full needle base using fluorine-free waterproof yarn;

[0073] Row 11 is a 2-needle face knitting and 1-needle face knitting with a tight bottom and hanging loop using microporous moisture-wicking yarn. Compared with row 9, it is shifted by 1 needle position and partially knitted at the bottom.

[0074] Row 12 is knitted with fluorine-free waterproof yarn as the base, and the top is knitted at the bottom loop stitches of row 11.

[0075] Rows 1 to 12 are the smallest cycle unit, and rows 13 to 20 are repeats of rows 1 to 8.

[0076] The purpose of the fluorine-free waterproof yarn woven surface layer 1 is to weave a moisture-conducting coil with hydrophobic function into the waterproof layer, so that moisture can be smoothly discharged to the shoe surface layer 1 and quickly spread on the surface layer 1, increasing the evaporation area and achieving a quick-drying effect.

[0077] After the fabric is woven, it still needs to undergo high-temperature treatment. For fabrics that do not use hot melt yarn, the high-temperature treatment is to allow the fabric to shrink fully under heat to achieve the desired fabric effect; for fabrics that use hot melt yarn, the high-temperature treatment is required to melt and bond the hot melt yarn into the fabric to achieve the desired fabric effect. The high-temperature treatment temperature for hot melt yarn is approximately 85℃-160℃.

[0078] Example 5

[0079] The difference between this embodiment and embodiment 4 is that the hydrophilic fiber here is used for 1-needle surface knitting, while 1-needle surface knitting with tight bottom hanging stitches is used as an auxiliary 1-needle surface knitting.

[0080] Taking hydrophilic fibers as microporous moisture-absorbing yarn and water-repellent fibers as fluorine-free waterproof yarn as an example,

[0084] The third row is a 1-stitch face knit and a 1-stitch face knit bottom tight hanging eye knit with microporous moisture-absorbing yarn. Compared with the first row, the position is shifted by 1 stitch.

[0085] The fourth row is knitted with a full needle base using fluorine-free waterproof yarn;

[0086] The fifth row is a 1-needle face knitting and a 1-needle face knitting bottom tight hanging eye knitting with microporous moisture-absorbing yarn. Compared with the third row, it is shifted by 1 needle position and the bottom knitting is done in a local area.

[0087] The 6th row is knitted with fluorine-free waterproof yarn as the base, and the top is knitted at the bottom loop stitches of the 5th row.

[0088] The 7th row is a 1-stitch face knit and a 1-stitch face knit bottom tight hanging eye knit with microporous moisture-wicking yarn. Compared with the 5th row, the position is shifted by 1 stitch.

[0089] The 8th row is knitted with a full needle base using fluorine-free waterproof yarn;

[0090] Row 9 is a 1-stitch face knitting and 1-stitch face knitting with a tight bottom and hanging loop, with the position shifted by 1 stitch compared to row 7.

[0091] The 10th row is knitted with a full needle base using fluorine-free waterproof yarn;

[0092] Row 11 is a 1-needle face knitting and a 1-needle face knitting bottom tight hanging eye knitting with microporous moisture-absorbing yarn. Compared with row 9, it is shifted by 1 needle position and partially knitted at the bottom.

[0093] Row 12 is knitted with fluorine-free waterproof yarn as the base, and the top is knitted at the bottom loop stitches of row 11.

[0094] Rows 1 to 12 are the smallest cycle unit, and rows 13 to 20 are repeats of rows 1 to 8.
