Description

Technical Field

[0001] The invention relates to a shoe upper and a manufacturing method thereof, in particular to a braided shoe upper and a manufacturing method thereof. Background Art

[0002] Braided shoe uppers have been widely used in various sports shoes due to their good air permeability and comfort. However, due to the relatively soft and non-wear-resistant characteristics of the fabric, the wear resistance and deformation resistance of the braided shoe uppers are relatively low. Therefore, many braided shoe uppers are improved by sewing or pasting reinforcing strips or wear-resistant sheets. For example, a Chinese utility model patent with authorization announcement number CN207355597U discloses a new type of wear-resistant braided shoe upper, including a braided shoe upper body, a reinforcing front helper is bonded to the outer wall of one side of the top of the braided shoe upper body, and the reinforcing front helper is bonded to the outer wall of the top side of the braided shoe upper body. The woven upper body is provided with air holes near the position of the reinforced front helper, and the woven upper body is sewn with a breathable mesh near the position of the air holes, the outer wall of the woven upper body away from the breathable mesh is sewn with a dustproof breathable pad near the position of the air holes, the outer wall edge of the woven upper body away from the breathable mesh is sewn with a reinforcement strip, the woven upper body is sewn with a semicircular elastic piece near the bottom of the breathable mesh, the outer wall of the woven upper body close to the semicircular elastic piece is sewn with an upper piece, and the woven upper body and the outer wall of the upper piece are both bonded with waist-shaped rubber pieces. Although this method can improve the wear resistance and anti-deformation ability of the woven upper, the manufacturing process is complicated and it will inevitably increase the weight of the shoes, which is inconsistent with the design concept of lightweight sports uppers.

[0003] In view of this, the inventor conducted an in-depth study on the above-mentioned problem, and thus the present invention was produced. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 The following is a schematic diagram of the unfolded structure of the upper prepared in the embodiment.

[0018] The corresponding markings in the figure are as follows: 10-shoe upper body; 11-shoe toe position; 12- mid-waist position; 13- eyelet position; 14-Neckline position. DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1As shown, this embodiment provides a woven vamp, including a vamp body 10 obtained by yarn weaving, and the toe position 11, the middle waist position 12, the eyelet position 13 and / or the collar position 14 of the vamp body are sprayed with a reinforcement coating. In this embodiment, the above positions are sprayed with a reinforcement coating. If necessary, the reinforcement coating can also be sprayed at the position between the toe position 11 and the middle waist position 12 of the vamp body. It should be noted that there is only one toe position 11 of the vamp body 1, which is located at the position of the vamp body 10 corresponding to the tip of the shoe, there are two middle waist positions 12, which are respectively located at the positions corresponding to the middle of the vamp body and the left and right sides of the shoe, there is one eyelet position 13, which is the position where the vamp body 10 surrounds the tongue, and there is one collar position 14, which is the position where the vamp body 10 surrounds the shoe mouth.

[0021] The coating material used in the strengthening coating can be determined according to actual needs. In this embodiment, the ink used in the strengthening coating includes the following components in percentage by mass: Pigment (specific color can be determined according to actual needs): 30-40 parts; Waterborne polyurethane: 15-25 parts; Propylene glycol: 5-10 parts; Ethylene glycol: 5-10 parts; Glycerin: 3-8 parts; Dispersant: 1-3 parts; Defoaming agent: 0.1-0.5 parts; Thickener: 0.5-2 parts; Preservatives: 0.1-0.5 parts; Adhesive: 7-10 parts; Cationic colloidal silicon dioxide: 1-3 parts; Cross-linking agent: 0.5-2 parts; Deionized water: balance.

[0022] Among the above components, the content of water-based polyurethane is greater than the conventional ink dosage, which can enhance the ink's ability to form a film on the textile surface, thereby increasing wear resistance. The content of pigment is also greater than conventional ink, which can make the ink cover the textile more uniform and firmer, thereby improving wear resistance and durability. The use of cross-linking agent can form a cross-linking network between polymers in the ink, enhance the mechanical properties and chemical resistance of the ink film, thereby improving durability. The use of adhesive can enhance the adhesion between the ink and textile fibers. The use of cationic colloidal silica can react with the adhesive to form a film, further enhancing the adhesion of the ink.

[0023] The thickness of the reinforcing coating is 0.05-0.20 mm. Preferably, a texture pattern (not shown in the figure) is formed on the reinforcing coating, so that the concave and convex lines of the texture pattern can be used to improve the support strength of the corresponding position of the woven shoe surface.

[0024] This embodiment also provides a method for manufacturing the above-mentioned woven shoe upper, comprising the following steps performed in sequence: S1, prepare the blank, use a knitting machine to weave to obtain a woven cloth, and then dye, refine, degrease and shape the woven cloth to obtain the blank cloth. The specific type of the knitting machine and the specific weaving process can be determined according to actual needs, such as using a flat knitting machine for weaving. Preferably, this embodiment provides two weaving processes as follows: The first weaving process is that the knitting machine is a jacquard warp knitting machine with more than four combs, wherein the four combs are arranged in the order of GB1, GB2, JB1 and JB2 on the jacquard warp knitting machine, wherein JB1 and JB2 are jacquard combs, the inlay yarn structure of GB1 is 1-0-1-1 / 1-2-1-1 / / , the inlay yarn structure of GB2 is 2-3-2-2 / 1-0-1-1 / / , the inlay yarn structure of JB1 is 1-0-1-1 / 1-2-1-1 / / , the inlay yarn structure of JB2 is 1-0-1-1 / 1-2-1-1 / / , GB1, GB2, JB1 and JB2 are all threaded in a full-threading manner, and a single-layer jacquard warp knitted fabric can be obtained as a woven cloth after weaving.

[0025] In the second weaving process, the knitting machine is a shuttle loom. The yarn diameter used by the shuttle loom to make the woven cloth corresponding to the toe position, mid-waist position, eyelet position and / or collar position of the upper body is larger than the yarn diameter used by the shuttle loom to make other parts of the woven cloth, which helps to improve the strength of the corresponding parts and improve the support performance of the woven upper. During the weaving process, the density of the upper pattern can be controlled by adjusting the parameters of the shuttle loom, such as the tension of the warp and weft yarns, the width of the shuttle eye, etc., and the twist hole structure can be formed by setting the movement of the twisted heddle body and the lifting heddle to enhance the air permeability of the upper.

[0026] The specific treatment methods of dyeing, refining and degreasing and shaping can be conventional methods. Preferably, in this embodiment, the pH value of the refining and degreasing treatment is 6-7, the treatment temperature is 80-100°C, the treatment time is 3-60 minutes, and the amount of degreasing agent is 0.5-1.5g / L, which helps to enhance the adhesion between the ink and the upper body during subsequent printing.

[0027] S2, cutting and dividing, according to the style and size requirements, the grey cloth is electro-engraved and cut to obtain multiple upper bodies. If necessary, the upper bodies can also be embroidered. The specific embroidery processing method is a conventional method, such as color embroidery, rope embroidery or water-soluble embroidery.

[0028] S2.1. Printing of the base material: Printing is performed at the positions corresponding to the toe, mid-waist, eyelets and / or collar of the upper body to form a base material layer. Specifically, existing liquid piezoelectric inkjet technology is used, and ink is sprayed onto the surface of the fabric using a conventional micro-piezoelectric print head, and penetrates into the fiber to fix the color. The nozzle diameter of the micro-piezoelectric print head is 25μm-50μm, which helps to prevent the coating from falling off or fading.

[0029] S3, coating printing, repeatedly spraying reinforcing ink on the upper body and the corresponding parts of the toe position, mid-waist position, eyelet position and / or collar position of the upper body to stack them to form a reinforcing coating, that is, the reinforcing coating is a multi-layer structure with multiple layers stacked on each other, and the spraying paths between two adjacent layers are different, that is, the textures between two adjacent layers are different, so that a texture effect similar to yarn weaving can be formed, which better matches the weaving texture of the upper body and improves the appearance of the shoe. In addition, the reinforcing coating is preferably located on the base material layer, and the thickness of the reinforcing coating is preferably 0.05-0.20mm, so that it can have a certain three-dimensional visual effect.

[0030] S4, drying, putting the upper body after the coating spraying into an oven for drying to obtain a woven upper, the drying temperature is 140° C., and the drying time is 8-15 minutes.

[0031] The present invention is described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, which all belong to the protection scope of the present invention.
