Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vamp, in particular to a vamp and a manufacturing method thereof. BACKGROUND

[0002] The existing shoe products balance the cost and use environment in terms of durability, weight and air permeability, and can also be customized according to different activity scenarios. At present, a leno woven fabric is used as a vamp, and through the weaving structure of weft yarns and warp yarns, combined with sweat-absorbing, antibacterial and heat-conducting yarns, a non-uniform pattern is designed to improve the air permeability, stretchability and strength of the vamp, and different hole shapes are customized through the yarn configuration of different areas. The durability and air permeability of the shoe product are improved while keeping the cost and environmental impact low, the needs of different activity scenarios are met, and the comfort and performance are improved.

[0003] The warp yarns of the woven vamp are parallel to the longitudinal direction of the vamp body, so the vamp has relatively poor extensibility in the longitudinal direction of the vamp body, and the elasticity of the vamp itself is insufficient, so the comfort and stretchability of the finished shoe are relatively weak. The existing vamp often uses elastic yarns to solve this problem, but due to the warp-weft interlacing structure of the woven fabric, the use of elastic yarns alone has limited effect on the improvement of the stretchability of the vamp. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application aims to provide a vamp to solve the problems of the prior art.

[0005] In order to achieve the above-mentioned purpose, the present application is realized by the following technical scheme: it comprises a vamp body made of a leno weave, the leno weave comprising a plurality of warp yarns and a plurality of weft yarns, the warp yarns and the weft yarns being interlaced to form a "X-shaped" oblique arrangement, the warp yarns and the weft yarns extending along their respective length directions and forming an angle with the longitudinal direction of the vamp body, the angle being in the range of 30°-60°. The longitudinal direction is defined as the direction along the instep in the vamp body. By tilting the original "cross-shaped" shoe type template, the warp yarns are still woven in the vertical direction and the weft yarns are still woven in the horizontal direction during the weaving process, and the warp yarns and the weft yarns on the finished vamp form an "X-shaped" oblique arrangement, so as to better utilize the oblique elasticity of the leno fabric and make the vamp have good elasticity in the longitudinal direction.

[0006] Preferably, the warp yarns and the weft yarns are perpendicular to each other.

[0007] Preferably, the warp yarns and the weft yarns are made of inelastic yarns. When the warp yarns and the weft yarns are made of inelastic yarns, the oblique elasticity of the leno fabric is utilized, and the oblique direction of the leno fabric is adjusted to the longitudinal direction by the oblique arrangement method, so as to realize the improvement of the elasticity of the vamp.

[0008] Preferably, the yarn material of the warp and weft yarns is elastic yarn, and the woven fabric comprises a tensile thread embedded in the leno weave at regular intervals. When the warp and weft yarns are made of elastic yarn, the overall elasticity of the vamp can be significantly improved. However, due to the elasticity of the diagonal row itself, the use of elastic yarn may cause the vamp to be too elastic, leading to easy deformation of the vamp and adversely affecting the durability and tear resistance of the vamp. Therefore, a tensile thread is needed to strengthen the vamp. The tensile thread can be used in combination with at least one of the warp and weft yarns, or embedded in the leno weave at regular intervals.

[0009] Preferably, the tensile thread has a breaking strength of ≥1.64 cN / dtex to maintain the tension and shape of the woven structure of the vamp.

[0010] Preferably, the tensile thread has a spacing of 2-5 mm. When the spacing is too dense, the vamp may lose some elasticity and flexibility. When the spacing is too sparse, the overall strength of the vamp is not sufficiently enhanced.

[0011] Preferably, the weft yarns can also simultaneously use at least one of sweat-absorbing yarn, antibacterial yarn, heat-conducting yarn, and combinations thereof. The use of functional yarns can expand the functions of the vamp.

[0012] A vamp, wherein the leno weave is distributed in at least part of the toe end, midfoot, and heel end of the vamp, and accounts for more than 50% of the vamp. The toe end is the toe area, i.e. the projection area from the toes to the first metatarsophalangeal joint. The midfoot is the side area, i.e. the projection area from the first metatarsophalangeal joint to the heel counter. The heel end is the heel counter area. The leno weave accounts for more than 50% of the vamp, and the leno weave has high elasticity. The distribution of the leno weave in more than half of the vamp and in the front, middle, and back parts of the vamp helps to balance the tension of the vamp, making the vamp elastic and uniform, and improving the comfort of the wearer.

[0013] Preferably, the leno weave extends from the toe end of the vamp to the midfoot and heel end of the vamp. The leno weave is continuously distributed throughout the vamp, and the tension and elasticity of the vamp are uniform.

[0014] A method for manufacturing a vamp, the method comprising: The vamp body is made of the leno weave, which comprises a plurality of warp yarns and a plurality of weft yarns, and the warp and weft yarns are interlaced to form a woven fabric; The leno weave is woven by tilting a shoe pattern plate by 30° to 60°; The warp yarns extend along the length direction and form an angle of 30° to 60° with the longitudinal direction of the vamp body; The weft yarns extend along the length direction and form an angle of 30-60 degrees with the longitudinal direction of the vamp body, and the angle is complementary to the angle between the warp yarns and the longitudinal direction of the vamp body.

[0015] The present application has the following advantages: 1. By tilting the original "cross-type" layout, the warp and weft yarns form a "X-type" oblique orthogonal layout, which better utilizes the oblique elasticity of the woven fabric, especially the leno fabric, so that the vamp has good elasticity without using special elastic yarns.

[0016] 2. By combining the physical properties of the warp (weft) yarns, such as elasticity, sweat absorption, antibacterial, heat conduction, etc., the shoe product has better comfort, breathability, antibacterial, etc.

[0017] 3. The addition of anti-tension threads in the warp and weft yarns not only enhances the tear resistance of the vamp, but also provides good wrapping and support by inhibiting the deformation caused by excessive elasticity of the vamp. BRIEF DESCRIPTION OF DRAWINGS

[0019] Main figure mark explanation: 1, leno weave DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the following will further describe the present application in conjunction with specific embodiments.

[0021] In some embodiments, the upper discussed herein includes an upper body made of a leno weave 1, which comprises multiple warp yarns and multiple weft yarns interwoven together. The warp and weft yarns extend along their respective length directions and each forms an angle with the longitudinal direction of the upper body, the angle ranging from 30° to 60°. The longitudinal direction is defined as the direction along which the foot travels within the upper body; that is, when the upper body is in normal use, the direction extending along the user's foot from heel to toe is the defined longitudinal direction. Similarly, the transverse direction is the direction perpendicular to the longitudinal direction.

[0022] Figure 1 This is a schematic diagram of the structure of a shoe upper according to the present invention. Figure One , Figure 2 This is a schematic diagram of the structure of a shoe upper according to the present invention. Figure Two By tilting the original "cross-shaped" shoe pattern and changing the layout from a forward arrangement to a diagonal arrangement, the warp yarns are still woven in the vertical direction and the weft yarns are still woven in the horizontal direction during the weaving process. Finally, the warp and weft yarns on the finished shoe upper form an "X" diagonal orthogonal layout, so as to better utilize the diagonal elasticity of the woven fabric, especially the gauze fabric 1, so that the shoe upper has good elasticity in the longitudinal direction.

[0023] The angle between the warp and weft yarns and the longitudinal direction of the shoe upper body ranges from 30° to 60°. Figure 3 This is a schematic diagram of the layout where the warp yarns and the longitudinal direction of the shoe upper body form a 30° angle. In some embodiments, the angle between the warp yarns and the longitudinal direction of the shoe upper body is 30°, while the angle between the weft yarns and the longitudinal direction of the shoe upper body is 60°. In this case, the 30° diagonal arrangement has a certain effect on improving the elasticity of the shoe upper. Figure 4 This is a schematic diagram illustrating the layout of the warp yarns and the longitudinal direction of the shoe upper body, forming a 60° angle. In some embodiments, the angle between the warp yarns and the longitudinal direction of the shoe upper body is 60°, while the angle between the weft yarns and the longitudinal direction of the shoe upper body is 30°. In this case, the 60° diagonal arrangement enhances the elasticity of the shoe upper. Furthermore, the 30° and 60° diagonal arrangements can be combined to create a symmetrical shoe upper for enhanced aesthetics, or they can be left uncombined to create an asymmetrical shoe upper for added individuality. Figure 5 This is a schematic diagram showing the layout of the warp yarns and the longitudinal direction of the shoe upper body forming a 45° angle. In some embodiments, the angle between the warp yarns and the longitudinal direction of the shoe upper body is 45°, resulting in a 45° diagonal arrangement. At this angle, the shoe upper presents a positive "X" shape, and the elasticity of the shoe upper reaches its maximum among various angles within the diagonal arrangement range, significantly improving the elasticity of the shoe upper. In some embodiments, the warp and weft yarns are perpendicular to each other.

[0024] In some embodiments, the warp yarns and the weft yarns are made of inelastic yarns. The warp yarns and the weft yarns are arranged in a "X" pattern by being arranged diagonally, so that the upper has good flexibility in the longitudinal direction.

[0025] In some embodiments, the warp yarns and the weft yarns are made of elastic yarns, and the leno weave includes a tensile line. When the warp yarns and the weft yarns are made of elastic yarns, the elasticity of the upper can be significantly improved. In some embodiments, when the tensile line is included in the warp yarns, the deformation problem caused by excessive elasticity of the upper can be inhibited to some extent. In some embodiments, when the tensile line is included in the weft yarns, the problem of excessive elasticity of the upper can be solved to some extent, and the deformation caused by excessive elasticity can be limited. In some embodiments, when the tensile line is included in both the warp yarns and the weft yarns, the problem of excessive elasticity of the upper can be effectively solved, the deformation caused by excessive elasticity can be limited, and better support can be provided.

[0026] The tensile line has a breaking strength of ≥1.64 cN / dtex. The higher the breaking strength of the tensile line, the better the tear resistance and deformation resistance, the problem of excessive elasticity of the upper can be effectively solved, the deformation caused by excessive elasticity can be limited, and better support can be provided.

[0027] In some embodiments, the tensile line has a spacing of 2-5 mm. In some embodiments, when the warp yarns and the weft yarns contain elastic yarns, the tensile line has a spacing of 2-4 mm to limit deformation and enhance the strength of the upper. In some embodiments, when the warp yarns and the weft yarns do not contain elastic yarns and are arranged diagonally at 45°, the tensile line has a spacing of 4-5 mm to enhance support.

[0028] In some embodiments, the weft yarns can also simultaneously use at least one of sweat-absorbing yarns, antibacterial yarns, heat-conducting yarns, and combinations thereof, so that the performance and comfort of the wearer's feet can be improved by the use of functional yarns. In some embodiments, different regions or different positions in different regions of the upper can be customized to meet the needs of the wearer. In addition, the leno weave 1 also includes a uniform honeycomb pattern or a non-uniform other pattern. The uniform honeycomb pattern can form good ventilation channels, so that the air inside and outside the shoe can be fully exchanged, the foot sweat can be discharged in time, and the wearing comfort can be improved. The non-uniform other pattern can be at least one of various geometric and / or non-geometric shapes and combinations thereof, which can be used to provide good air permeability, comfort, and interest.

[0029] Figure 6For the structure of the upper applied to a specific shoe product, in some embodiments, the herringbone weave 1 is distributed in at least part of the toe end, midfoot and heel end of the upper, and accounts for more than 50% of the upper. Among them, the toe end is the toe area, that is, the projection area from the toes to the first metatarsophalangeal joint, the midfoot is the side area, that is, from the first metatarsophalangeal joint to the heel counter, and the heel end is the heel counter area. The herringbone weave accounts for more than 50% of the upper, has large elasticity, accounts for more than half of the upper and is distributed in the front, middle and rear parts of the upper, which is beneficial to balance the tension of the upper, make the elasticity of the upper uniform, and improve the comfort of the wearer.

[0030] In some embodiments, the herringbone weave 1 extends from the toe end of the upper to the midfoot and heel end of the upper. The herringbone weave 1 is continuously distributed on the entire upper, balancing the tension and elasticity of the entire upper.
