Description

Technical Field

[0001] This utility model relates to the field of flyknit shoe upper technology, specifically a dirt-resistant flyknit shoe upper. Background Technology

[0002] Flyknit uppers are typically knitted using a flyknitting machine, and different textures or patterns can be achieved through knitting.

[0003] According to application number CN202320243911.1, a one-piece molded flyknit upper is disclosed, including a polymer sole plate, a first flyknit upper and a second flyknit upper. The polymer sole plate has ventilation holes arranged in the front middle, front side, middle side and rear side. The first flyknit upper is woven and sewn onto the surface of the polymer sole plate and is arranged corresponding to the ventilation holes. The second flyknit upper is woven and sewn onto the bottom of both sides and the top of the rear side of the polymer sole plate.

[0004] The flyknit uppers in the above cases lack stain resistance, making the surface of the shoe prone to contamination. They easily attract dust, oil stains, beverage residue, and other dirt. Furthermore, the breathability and antibacterial properties of the uppers are not ideal. Flyknit uppers fit snugly against the feet, and during exercise, sweat retention can easily lead to the proliferation of microorganisms such as E. coli and Staphylococcus aureus, producing odors and affecting hygiene and health. Sweat buildup inside the shoe exacerbates the stuffiness, and long-term wear may cause foot skin problems. Therefore, we offer a stain-resistant flyknit upper. Utility Model Content

[0005] The purpose of this invention is to provide a dirt-resistant flyknit upper to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dirt-resistant flyknit upper, comprising an upper body, a reinforcing strip sewn to the top of the front of the upper body, reinforcing patches sewn to the left and right sides of the front of the upper body, and several shoelace holes on the front of the upper body. The upper body is composed of a base layer, a first elastic layer, a connecting layer, a stain-resistant layer, a second elastic layer, an antibacterial and bacteriostatic layer, and a moisture-wicking layer.

[0007] Preferably, the first elastic layer is disposed on the front side of the base layer, the connecting layer is disposed on the front side of the first elastic layer, the anti-fouling layer is disposed on the front side of the connecting layer, the second elastic layer is disposed on the back side of the base layer, the antibacterial and bacteriostatic layer is disposed on the back side of the second elastic layer, and the moisture-wicking layer is disposed on the back side of the antibacterial and bacteriostatic layer.

[0008] Preferably, the connecting layer is composed of an odor-removing layer and a toughening layer, which are woven in a cross pattern. The base layer, the first elastic layer, the connecting layer, the second elastic layer, the antibacterial and bacteriostatic layer, and the moisture-wicking layer are all provided with interconnected breathable pores.

[0009] Preferably, the base layer is woven using a flyknit process, consisting of interwoven warp and weft yarns. The warp yarns are a blend of polyester and nylon fibers in a 7:3 ratio, and the weft yarns are spandex fibers. The weaving density is 8-12 needles / cm, forming a mesh support structure.

[0010] Preferably, both the first elastic layer and the second elastic layer are made of spandex elastic fibers.

[0011] Preferably, the odor-removing layer is made of coffee fiber, and the toughening layer is made of nylon fiber.

[0012] Preferably, the antifouling layer is made of porous polytetrafluoroethylene film, the antibacterial and bacteriostatic layer is made of chitin fiber and viscose fiber blended in a ratio of 3:7, and the moisture-wicking layer is made of ramie fiber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model improves the elasticity of the shoe upper by setting a first elastic layer and a second elastic layer, allowing each layer to deform synchronously when the shoe upper is bent, such as when the toes move, thus avoiding stress concentration between layers. The odor-removing layer effectively eliminates odors and reduces their generation. The toughness layer improves the shoe upper's resilience. The stain-resistant layer prevents dust, oil stains, and beverage stains from easily adhering to the shoe upper. After simulating stains such as soy sauce and engine oil splashes, the shoe upper can be completely cleaned with water without the need for detergent. The antibacterial and bacteriostatic layer enhances its resistance to... The chitosan has antibacterial and antimicrobial effects. The amino groups in the chitosan molecule can destroy bacterial cell membranes, achieving an antibacterial rate of ≥95% against Escherichia coli and Staphylococcus aureus. By incorporating a moisture-wicking layer, the moisture-wicking effect of the shoe upper is improved. The moisture-wicking layer is made of ramie fiber, and its internal cavity structure can absorb 20% of its own weight in water. The core absorption height reaches 15cm / 30min, which can quickly guide sweat from the feet to the outside of the shoe upper for evaporation. Combined with the antibacterial and antimicrobial layer, it can inhibit the odor substances produced by the decomposition of sweat. Through the combination of breathable holes and a porous polytetrafluoroethylene film, it can quickly expel moisture from the feet and keep the inside of the shoe dry.

[0015] 2. This utility model improves the tensile strength of the shoelace hole area and both sides of the shoe body by setting reinforcing strips and reinforcing patches, reducing deformation or tearing caused by shoelace pulling, and improving the service life of the shoe upper.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A dirt-resistant flyknit upper includes an upper body 1, a reinforcing strip 2 sewn on the top of the front of the upper body 1, reinforcing patches 3 sewn on the left and right sides of the front of the upper body 1, and several shoelace holes 4 on the front of the upper body 1.

[0022] By setting reinforcement strip 2 and reinforcement patch 3, the tensile strength of the shoelace eyelet area 4 and both sides of the shoe body is improved, reducing deformation or tearing caused by shoelace pulling and improving the service life of the shoe upper.

[0023] The upper body 1 is composed of a base layer 101, a first elastic layer 102, a connecting layer 104, a stain-resistant layer 105, a second elastic layer 106, an antibacterial and bacteriostatic layer 107, and a moisture-wicking layer 108. The first elastic layer 102 is located on the front of the base layer 101. The base layer 101 is woven using a flyknit process, consisting of interwoven warp and weft yarns. The warp yarns are a blend of polyester and nylon fibers in a 7:3 ratio, and the weft yarns are spandex fibers. The weaving density is 8-12 stitches / cm, forming a mesh. The structure comprises a support layer 104, which is disposed on the front side of the first elastic layer 102. An anti-fouling layer 105 is disposed on the front side of the support layer 104. The anti-fouling layer 105 is made of a porous polytetrafluoroethylene (PTFE) film with a thickness of 20-50 μm, a micropore diameter of 0.1-0.8 μm, a porosity of 80%-90%, and a surface energy ≤30 mN / m. It is bonded to the support layer 104 via a hot-pressing process. A second elastic layer 106 is disposed on the back side of the base layer 101. Both the first elastic layer 102 and the second elastic layer 106 are made of spandex elastic fibers, with a spandex content ≥90% and a breaking elongation ≥500%. An antibacterial and bacteriostatic layer 107 is located on the back of the second elastic layer 106. This layer is made of a blend of chitin fibers and viscose fibers in a 3:7 ratio, inhibiting the growth of microorganisms such as Escherichia coli and Staphylococcus aureus. A moisture-wicking layer 108 is located on the back of the antibacterial and bacteriostatic layer 107, wicking away moisture. The wicking layer 108 is made of ramie fiber, and the connecting layer 104 is composed of an odor-removing layer 109 and a toughness layer 110. The odor-removing layer 109 and the toughness layer 110 are woven in a cross pattern. The odor-removing layer 109 is made of coffee fiber, and the toughness layer 110 is made of nylon fiber. The base layer 101, the first elastic layer 102, the connecting layer 104, the second elastic layer 106, the antibacterial and bacteriostatic layer 107, and the moisture-wicking layer 108 are all provided with interconnected breathable holes 111.

[0024] The elastic layer is bonded by warp knitting to form an elastic layer with a thickness of 0.3-0.5mm on the front side, covering the entire area of ​​the base layer 101. On the back side, the spandex elastic fabric is pressed onto the back of the base layer 101 through a heat bonding process, with the temperature controlled at 120-140℃ and the pressure at 0.2-0.3MPa, to ensure a tight bond with the base layer 101.

[0025] The connecting layer 104 is woven, and the odor-removing layer 109 is a blend of coffee fiber and polyester fiber in a 5:5 ratio. It is woven into a loose layer with a thickness of 0.2 mm on the surface of the first elastic layer 102 using a fly loom, with an activated carbon loading of 5-10 g / m². 2 Toughness layer 110: Nylon fibers are woven laterally in 200D monofilaments on the surface of the odor-removing layer 109 to form a cross-grid structure with a grid spacing of 1-2mm, which improves the interlayer connection strength.

[0026] The anti-fouling layer 105 is applied by using a roller heat laminator to cover the front of the connecting layer 104 at a temperature of 150-160℃ and a pressure of 0.5MPa for 10-15 seconds. The edge of the film extends 2-3mm beyond the boundary of the connecting layer 104 and is trimmed by laser cutting to ensure alignment with the edge of the base layer 101.

[0027] The antibacterial and bacteriostatic layer 107 is integrated with the moisture-wicking layer 108. The antibacterial layer is a blended yarn of chitosan fiber and viscose fiber in a 3:7 ratio, woven into a 0.4mm thick knitted fabric using a circular knitting machine. The chitosan fiber is knitted on the outside, facing outwards to contact the sweat. The moisture-wicking layer is a 0.3mm thick mesh fabric woven from ramie fiber single yarn, with a mesh size of 1-1.5mm. The composite process involves bonding the antibacterial layer and the moisture-wicking layer using ultrasonic waves at a frequency of 20kHz and an amplitude of 30μm. The bonding is then pressed onto the back of the second elastic layer 106. The bonding points are dotted, with a diameter of 1mm and a spacing of 5mm, leaving more than 80% of the area unbonded to facilitate breathability.

[0028] Ventilation hole 111 calibration: The shoe upper is heat-set using a mold at a temperature of 90-100℃ to ensure that the ventilation holes 111 in each layer are completely aligned, forming a vertically connected ventilation channel.

[0029] By incorporating a first elastic layer 102 and a second elastic layer 106, the elasticity of the shoe upper is improved, allowing each layer to deform synchronously when the shoe upper bends, such as during toe movement, thus avoiding stress concentration between layers. The odor-removing layer 109 effectively removes odors and reduces their generation. The resilience layer 110 enhances the shoe upper's toughness. The stain-resistant layer 105 provides stain resistance, preventing dust, oil stains, and beverage stains from easily adhering to the shoe upper. After simulating stains such as soy sauce and engine oil splashes, the shoe upper can be completely cleaned with water without the need for detergent. The antibacterial and antimicrobial layer 107 further enhances its resistance to... The chitin molecule has antibacterial and antimicrobial effects. The amino groups in the chitin molecule can destroy bacterial cell membranes, with an antibacterial rate of ≥95% against Escherichia coli and Staphylococcus aureus. By setting up a moisture-wicking layer 108, the moisture-wicking effect of the shoe upper is improved. The moisture-wicking layer 108 is made of ramie fiber, and its internal cavity structure can absorb 20% of its own weight in water. The core absorption height reaches 15cm / 30min, which can quickly guide sweat from the feet to the outside of the shoe upper for evaporation. Combined with the antibacterial and antimicrobial layer 107, it can inhibit the odor substances produced by the decomposition of sweat. Through the combination of breathable holes 111 and porous polytetrafluoroethylene film, it can quickly expel moisture from the feet and keep the inside of the shoe dry.

[0030] When in use, the anti-fouling layer 105 is superhydrophobic. Liquid stains, such as rainwater, coffee, and soy sauce, will form beads and roll off after contact with the shoe surface. Solid dust is difficult to adhere due to its low surface tension. The ventilation holes 111 of each layer are interconnected and, together with the porous polytetrafluoroethylene film with a porosity of 80%-90%, form vertical ventilation channels. Foot moisture can be quickly discharged through the micropores of the film with a diameter of 0.1-0.8μm, while preventing dust from entering.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
