Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear technology, and in particular to a type of shoe upper leather. Background Technology
[0002] Leather shoes typically have uppers made of natural or synthetic leather, while the soles are made of materials such as leather, rubber, plastic, PU foam, and PVC. The uppers and soles are joined together through stitching, gluing, or injection molding. In summer, the temperature inside leather shoes is high. After the feet sweat, a warm and humid environment forms inside the shoe, causing discomfort and making the feet feel stuffy. Sweat also tends to stick to the shoe's fabric, reducing comfort. Utility Model Content
[0003] The technical problem this invention aims to solve is that the hot and humid environment inside leather shoes during the summer makes the feet feel stuffy and uncomfortable, and the moisture tends to stick to the inner fabric of the shoes, reducing their comfort.
[0004] To solve the above-mentioned technical problems, this utility model provides a shoe upper leather, comprising:
[0005] Cooling fiber layer;
[0006] A leather layer is placed on the outside of the cooling fiber layer;
[0007] The lining is placed between the cooling fiber layer and the leather layer;
[0008] The lining is bonded to the cooling fiber layer and the leather layer respectively;
[0009] The mesh size of the lining is larger than that of the cooling fiber layer.
[0010] Preferably, the material of the cooling fiber layer is cooling fiber.
[0011] Preferably, the cooling fiber layer is knitted by warp knitting.
[0012] Preferably, the cooling fiber layer includes multiple coils woven from cooling fibers. When the cooling fiber layer is stretched along the width of the shoe body, the coil height decreases and the coil width increases.
[0013] Preferably, it also includes a protective layer applied to the outside of the leather layer.
[0014] Preferably, the surface of the leather layer is provided with a grid pattern.
[0015] Preferably, the edge of the leather layer is provided with a wear-resistant layer, which has a smooth surface structure.
[0016] Compared with the prior art, the beneficial effects of this embodiment of shoe upper leather are as follows:
[0017] This invention discloses a shoe upper leather with a cooling fiber layer as the lining. Upon skin contact with the cooling fiber layer, an instant cooling sensation is generated, drawing away heat from the feet, reducing foot sweat, and improving the comfort of the shoe. A lining is placed between the cooling fiber layer and the leather layer. The mesh size of the lining is larger than that of the cooling fiber layer. The cooling fiber layer is only fixed to the yarn of the lining. There is no glue inside the mesh of the lining, nor on the corresponding area of the cooling fiber layer, ensuring the openness of the ventilation pores in the cooling fiber layer within the corresponding area of the lining mesh. Simultaneously, the lining absorbs excess glue on the cooling fiber layer and also helps to spread the glue evenly, preventing glue from seeping into the cooling fiber layer and clogging the ventilation pores. The lining prevents glue from blocking the ventilation pores of the cooling fiber layer, ensuring the breathability of the shoe upper leather.
[0018] The addition of a cooling fiber layer and lining enhances the cooling, heat dissipation, and breathability of the shoe, creating a dry and cool in-shoe environment and solving the technical problem of reduced comfort of leather shoes due to the humid and hot environment inside the shoe during summer.
[0019] Furthermore, the shoe upper leather of this utility model embodiment consists of only three layers of fabric: a leather layer, a lining, and a cooling fiber layer. During manufacturing, it is only necessary to apply glue to the inside and outside of the lining to bond the three layers of fabric together to form the shoe upper leather. This utility model has a simple and compact structure, and the manufacturing process is quick and concise, which improves the processing efficiency of footwear. Attached Figure Description

[0027] like Figure 1 As shown, a preferred embodiment of the present invention provides a shoe upper leather comprising a cooling fiber layer 1, a leather layer 2, and a lining 3. The leather layer 2 is disposed on the outside of the cooling fiber layer 1; the lining 3 is disposed between the cooling fiber layer 1 and the leather layer 2; wherein the lining 3 is bonded to the cooling fiber layer 1 and the leather layer 2 respectively, and the mesh of the lining 3 is larger than the mesh of the cooling fiber layer 1.
[0028] This invention relates to a shoe upper leather with a cooling fiber layer 1 as the lining. Upon skin contact with the cooling fiber layer 1, an instant cooling sensation is generated, drawing away heat from the feet, reducing sweating, and improving the comfort of the shoe. A lining 3 is provided between the cooling fiber layer 1 and the leather layer 2. The mesh size of the lining 3 is larger than that of the cooling fiber layer 1. The cooling fiber layer 1 is only fixed to the yarn of the lining 3. There is no glue inside the mesh of the lining 3, nor on the corresponding area of the cooling fiber layer 1, ensuring the openness of the ventilation holes in the cooling fiber layer 1 within the corresponding area of the lining 3 mesh. Simultaneously, the lining 3 absorbs excess glue on the cooling fiber layer 1 and also helps to spread the glue evenly, preventing glue from seeping into the interior of the cooling fiber layer 1 and clogging the ventilation holes. The lining 3 prevents glue from blocking the ventilation holes of the cooling fiber layer 1, ensuring the breathability of the shoe upper leather.
[0029] The addition of cooling fiber layer 1 and lining 3 enhances the cooling, heat dissipation, and breathability of the shoe, creating a dry and cool in-shoe environment and solving the technical problem of reduced comfort of leather shoes due to the humid and hot environment inside the shoe when wearing leather shoes in summer.
[0030] Furthermore, the shoe upper leather of this utility model embodiment consists of only three layers of fabric: leather layer 2, lining 3, and cooling fiber layer 1. During manufacturing, it is only necessary to apply glue to the inside and outside of the lining 3 to bond the three layers of fabric together to form the shoe upper leather. This utility model has a simple and compact structure, and the manufacturing process is quick and concise, which improves the processing efficiency of footwear.
[0031] Specifically, the material of the cooling fiber layer 1 is cooling fiber 4. In making cooling fiber 4, firstly, fiber raw materials with cooling, heat-removing, and moisture-absorbing properties are selected, such as mica, jade, pearl, and maifan stone; then, the raw materials are pulverized using a nano-level pulverization process; finally, the pulverized raw materials are processed into cooling fibers according to the manufacturing process. Because raw materials such as jade and mica are highly thermally conductive, these materials can quickly conduct heat from the skin surface to the outside world after contact with the skin, producing an instant cooling sensation. Therefore, cooling fiber 4 also has a cooling and heat dissipation function.
[0032] Generally speaking, fabric weaving methods are usually divided into knitting and woven fabrics. Woven fabrics are formed by interlacing two or more sets of yarns perpendicular to each other as warp and weft. The longitudinal yarns are called warp yarns, and the transverse yarns are called weft yarns. Because the warp and weft yarns of woven fabrics intersect perpendicularly, they form a tight mesh structure. The warp and weft yarns generate greater frictional resistance at the interlacing points, which restricts the relative movement of the warp and weft yarns. Therefore, woven fabrics have higher rigidity and a stiffer texture.
[0033] Knitting refers to the process of using knitting needles to form loops from various raw materials and types of yarn, and then connecting them to form a knitted fabric. A loop is formed by the spatial bending of yarn. When the knitted fabric is subjected to external force, the height and width of the loop will change. The direction of the external force affects the changes in the height and width of the loop. Therefore, knitted fabrics have advantages such as high extensibility, good elasticity, good breathability, and a soft hand feel. Since the cooling fiber layer is used as the lining in this embodiment of the invention, the selection of the weaving process should primarily consider breathability and comfort. Therefore, in this embodiment of the invention, the cooling fiber layer 1 is made using a knitting process.
[0034] Knitting methods are generally divided into weft knitting and warp knitting. Weft knitting involves forming loops of one or more yarns sequentially in the transverse direction (weft) of the fabric. Weft-knitted fabrics have advantages such as excellent elasticity and soft touch, but also disadvantages such as easy unraveling and curling, poor shape retention, and low production efficiency. Warp knitting involves forming loops of multiple yarns sequentially in the longitudinal direction (warp) of the fabric. When used in leather shoes, shoe uppers mainly bear transverse tension. Although warp-knitted fabrics are not as elastic and breathable as weft-knitted fabrics, their advantages of stable structure, resistance to deformation, transverse tensile strength greater than longitudinal tensile strength, and high production efficiency make them more suitable for use as linings of shoe uppers. Therefore, in this embodiment of the invention, the knitting process for the cooling fiber layer 1 is warp knitting.
[0035] Furthermore, considering that shoe upper leather primarily bears lateral tensile stress when used in leather shoes, to ensure the lateral tensile strength and breathability of the shoe upper leather, the extension direction of the cooling fibers 4 in the cooling fiber layer 1 should be the same as the length direction of the shoe body (i.e., the X to Y direction). That is, when the cooling fiber layer 1 is used in the shoe upper, the X to Y direction of the cooling fiber layer 1 should correspond to the length direction of the shoe body, and the X to Z direction of the cooling fiber layer 1 should correspond to the width direction of the shoe body. Figure 2 As shown. The cooling fiber layer 1 includes multiple coils 5 woven from cooling fibers 4. When the cooling fiber layer 1 is stretched along the width direction of the shoe body (i.e., the X to Z direction), the height of the coils 5 decreases and the width of the coils 5 increases, thereby opening the ventilation holes of the cooling fiber layer 1.
[0036] Furthermore, to ensure comfort inside the shoe, the cooling coefficient of the cooling fiber layer should not be too low. The cooling coefficient measures the thermal conductivity of a material by the "maximum heat flow" at the moment of contact. The higher the cooling coefficient, the more pronounced the instantaneous cooling sensation of the fabric. A cooling coefficient greater than or equal to 0.2 indicates a strong cooling sensation. Generally, in summer outdoor scenarios, rapid heat dissipation is required, and sportswear and windbreakers typically use fabrics with a cooling coefficient greater than or equal to 0.2. Considering that the upper leather of this embodiment is used for leather shoes, and the interior of leather shoes is a nearly enclosed space, the cooling coefficient of the cooling fabric used should be appropriately higher than that of sportswear and windbreakers. Therefore, the cooling coefficient of the cooling fiber layer in this embodiment is 0.24, and the thickness is 0.3mm.
[0037] Furthermore, the direct bonding of leather layer 2 and cooling fiber layer 1 can clog the mesh of cooling fiber layer 1, reducing the breathability of the upper leather. Therefore, this embodiment adds a lining 3 between leather layer 2 and cooling fiber layer 1. During the upper leather production, adhesive is applied to the inner and outer sides of the lining 3, and then leather layer 2 and cooling fiber layer 1 are respectively bonded to the outer and inner sides of the lining 3. The amount of adhesive should be controlled to be sufficient to bond leather layer 2 and cooling fiber layer 1 without soaking into them. When selecting the lining 3, the size of its mesh should be considered. If the mesh of the lining 3 is too small, the adhesive applied to the lining 3 will seep into the mesh, clogging it and affecting the breathability of the upper leather; if the mesh of the lining 3 is too large, the leather layer 2, cooling fiber layer 1, and lining 3 cannot form a reliable bond, easily causing relative displacement and a poor wearing experience. Therefore, in this embodiment of the invention, the mesh size of the lining fabric 3 is controlled to be between 1mm and 2mm.
[0038] In some preferred embodiments of this invention, the leather layer 2 is made of processed natural shoe upper leather, such as animal leather.
[0039] In some preferred embodiments of this invention, a protective layer is further included, which is applied to the outer side of the leather layer 2. Specifically, the protective layer can prevent the leather from being scratched or soiled, and facilitates polishing the leather, improving its appearance.
[0040] In some preferred embodiments of this invention, the surface of the leather layer 2 is provided with a mesh pattern. Specifically, the mesh pattern facilitates cleaning or the flow of water on the shoe surface.
[0041] In some preferred embodiments of this invention, the edge of the leather layer 2 is provided with a wear-resistant layer, which has a smooth surface structure. Specifically, the edge of the leather layer is prone to bumps and knocks, and the smooth structure can reduce friction.
[0042] In summary, this embodiment of the invention provides a shoe upper leather with a cooling fiber layer 1 as the lining. Upon skin contact with the cooling fiber layer 1, an instant cooling sensation is generated, drawing away heat from the feet, reducing foot sweat, and improving the comfort of the shoe. A lining 3 is provided between the cooling fiber layer 1 and the leather layer 2. The mesh size of the lining 3 is larger than that of the cooling fiber layer 1. The cooling fiber layer 1 is only fixed to the yarn of the lining 3. There is no glue inside the mesh of the lining 3, nor on the corresponding area of the cooling fiber layer 1, ensuring the openness of the ventilation holes in the cooling fiber layer 1 within the corresponding area of the lining 3 mesh. Simultaneously, the lining 3 can absorb excess glue on the cooling fiber layer 1 and also helps to spread the glue evenly, preventing glue from seeping into the interior of the cooling fiber layer 1 and clogging the ventilation holes. The lining 3 prevents glue from blocking the ventilation holes of the cooling fiber layer 1, ensuring the breathability of the shoe upper leather.
[0043] The addition of cooling fiber layer 1 and lining 3 enhances the cooling, heat dissipation, and breathability of the shoe, creating a dry and cool in-shoe environment and solving the technical problem of reduced comfort of leather shoes due to the humid and hot environment inside the shoe when wearing leather shoes in summer.
[0044] Furthermore, the shoe upper leather of this utility model embodiment consists of only three layers of fabric: leather layer 2, lining 3, and cooling fiber layer 1. During manufacturing, it is only necessary to apply glue to the inside and outside of the lining 3 to bond the three layers of fabric together to form the shoe upper leather. This utility model has a simple and compact structure, and the manufacturing process is quick and simple, which improves the processing efficiency of footwear.
[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
