A type of breathable sports shoe

Abstract

This invention relates to the field of footwear technology and discloses a breathable athletic shoe, comprising: an upper, which is a mesh-like, openwork knitted structure, with a sweat-wicking unit provided on one side of the upper; and a liquid-guiding structure on the surface of the cotton layer to facilitate liquid permeation. This invention incorporates a sweat-wicking unit on the mesh-like, openwork breathable upper. The cotton layer surface of the sweat-wicking unit is uniformly sprayed with polyethylene glycol fatty acid ester and reacted at 150°C for 120 seconds, causing the hydroxyl groups on the cotton layer surface to be esterified, thus reducing the hydrophilicity of the cotton layer and achieving a balance between hydrophilic and hydrophobic properties. This significantly improves dryness without affecting the skin-friendliness of the surface layer. Simultaneously, frustum-shaped perforations are formed in the cotton layer, allowing for faster drainage of moisture to the outside for air drying, further enhancing the shoe's dryness. In other words, the breathable mesh-like, openwork upper, combined with the sweat-wicking unit, improves the breathability of the athletic shoe.

Description

Technical Field

[0001] This invention relates to the field of footwear technology, specifically to a breathable athletic shoe. Background Technology

[0002] Athletic shoes are shoes designed and manufactured specifically for people participating in sports or travel. Unlike ordinary leather or rubber shoes, the soles of athletic shoes are generally soft and elastic, providing cushioning. They enhance elasticity during exercise and some even help prevent ankle injuries. Therefore, athletic shoes are essential for most sports activities, especially high-intensity physical activities such as basketball, running, and various everyday exercises.

[0003] Currently, mesh knit uppers are a common breathability feature in athletic shoes, but they still generally suffer from poor sweat wicking, which can affect foot health during prolonged exercise and urgently needs improvement.

[0004] Therefore, we provide a breathable athletic shoe to improve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a breathable sports shoe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a breathable sports shoe, comprising:

[0007] The upper is a mesh-like openwork knitted structure, with a sweat-wicking unit on one side of the upper;

[0008] The sweat-wicking unit includes a cotton layer, which includes at least one layer. The upper surface is coated with a polyethylene glycol fatty acid ester layer. After reacting at a high temperature of 150°C for 120 seconds, the hydroxyl groups on the surface of the cotton layer are esterified, and the surface hydrophilicity is reduced, forming a pure cotton spunlace nonwoven fabric layer with a hydroxyl esterified surface.

[0009] The surface of the cotton layer is also provided with a liquid-guiding structure that facilitates liquid penetration.

[0010] As an optional embodiment of the breathable sports shoe of the present invention, the liquid guiding structure includes a cavity groove opened on one side of the cotton layer, through holes are equally spaced on the strip of the cotton layer, the through holes are configured as frustum structures, one end of the through holes is connected to the cavity groove, a patch is correspondingly provided on the edge section of the cotton layer near the cavity groove, and a water-absorbing sheet for absorbing water liquid on the cotton layer is provided in the cavity groove.

[0011] As an optional embodiment of the breathable sports shoe of the present invention, wherein: the absorbent sheet is configured as a superabsorbent polymer resin layer, and one side of the absorbent sheet is inserted into the bottom of the cavity.

[0012] As an optional embodiment of the breathable sports shoe of the present invention, wherein: a connecting post is fixedly connected to the inner bottom of the cavity, a guide hole is provided in the middle of the connecting post, and one end of the guide hole is connected to a through hole.

[0013] As an optional embodiment of the breathable sports shoe of the present invention, wherein: the absorbent sheet has a slot on the side of the connecting post near the cavity, and the connecting post is inserted into the slot in a one-to-one manner.

[0014] As an alternative embodiment of the breathable sports shoe of the present invention, wherein: a raised strip is integrally provided on the side of the absorbent sheet away from the slot, and the raised strip is configured as an arc-shaped strip structure.

[0015] As an optional embodiment of the breathable sports shoe of the present invention, a cloth limiting plate is fixedly connected to the cavity port. The limiting plate is configured as a rectangular ring structure. One edge of the absorbent sheet is attached to the limiting plate, and a raised strip is integrally provided on the side of the absorbent sheet away from the slot corresponding to the ring opening of the limiting plate. The raised strip is configured as an arc-shaped strip structure.

[0016] As an optional embodiment of the breathable sports shoe of the present invention, wherein: a connecting strip is integrally provided on the other side of the absorbent sheet corresponding to the slot, and a connecting hole for communication is provided between the connecting strip and the slot, and a water guide plate is integrally provided at one end of each connecting strip, and the water guide plate is configured as a circular plate structure.

[0017] As an optional embodiment of the breathable sports shoe of the present invention, a plastic film is fixedly connected to the cavity port, and a second connecting hole is provided on the film corresponding to the connecting strip. The connecting strip is inserted into the second connecting hole one by one, and the film isolates the water-absorbing sheet and the water-guiding sheet.

[0018] As an alternative embodiment of the breathable sports shoe of the present invention, wherein: an opening is provided on one side of the shoe upper in conjunction with a sweat-wicking unit, and the edge of a patch is sewn with thread inside the opening.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This breathable athletic shoe features a sweat-wicking unit on its mesh-like, perforated upper. The cotton layer of the sweat-wicking unit is evenly coated with polyethylene glycol fatty acid ester and reacted at 150°C for 120 seconds, causing the hydroxyl groups on the cotton layer to be esterified. This reduces the hydrophilicity of the cotton layer, achieving a balance between hydrophilic and hydrophobic properties. When applied to the upper, this significantly improves dryness without affecting the skin-friendliness of the surface layer. Additionally, frustum-shaped perforations are created in the cotton layer, allowing moisture to be quickly directed to the outside for air drying, further enhancing the shoe's dryness.

[0021] Furthermore, a water-wicking plate is placed on the back of the cotton layer, which can improve the dryness performance on the basis of the cotton layer, allowing the shoe to be breathable and wick away moisture;

[0022] In other words, the breathable mesh upper, combined with a sweat-wicking unit, can improve the breathability of athletic shoes. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-6 A breathable athletic shoe, comprising:

[0035] The upper 4 is a mesh-like openwork knitted structure, with a sweat-wicking unit on one side of the upper;

[0036] The sweat-wicking unit includes a cotton layer 1, which includes at least one layer. The upper surface is coated with a polyethylene glycol fatty acid ester layer. After reacting at a high temperature of 150°C for 120 seconds, the hydroxyl groups on the surface of the cotton layer 1 are esterified, and the surface hydrophilicity is reduced, forming a pure cotton spunlace nonwoven fabric layer with a hydroxyl esterified surface.

[0037] The surface of cotton layer 1 is also provided with a liquid-guiding structure that facilitates liquid penetration.

[0038] The liquid guiding structure has a cavity 101 on one side of the cotton layer 1. Through holes 2 are equally spaced on the strip of the cotton layer 1. The through holes 2 are set as a frustum structure. One end of the through hole 2 is connected to the cavity 101. A patch 3 is set on the edge of the cotton layer 1 near the cavity 101. The surface of the cotton layer 1 is sprayed with a polyethylene glycol fatty acid ester layer. The polyethylene glycol fatty acid ester layer is locally esterified and arranged on the cotton layer 1 by reacting at a high temperature of 150°C for 120 seconds.

[0039] It should be noted that in this embodiment 1, an opening is made on one side of the shoe upper 4 to accommodate the sweat-wicking unit. The edges of the patch 3 are sewn together with silk thread inside the opening to improve the sweat-wicking effect on the shoe upper 4.

[0040] Specifically, in this application, polyethylene glycol fatty acid ester is uniformly sprayed onto the surface of cotton layer 1. After reacting at 150°C for 120 seconds, the hydroxyl groups on the surface of the pure cotton spunlace nonwoven fabric of cotton layer 1 are esterified, resulting in a decrease in the hydrophilicity of cotton layer 1 and achieving a balance between hydrophilicity and hydrophobicity. Applying cotton layer 1 to the shoe upper 4 significantly improves dryness without affecting the skin-friendliness of cotton layer 1 against the foot, thus enhancing the dryness effect during use. Simultaneously, frustum-shaped through-holes 2 are formed on cotton layer 1, with the larger end of the through-hole 2 opening on the front side of cotton layer 1, allowing sweat to be more quickly directed to the outside through the through-holes 2.

[0041] The cavity 101 is equipped with a water-absorbing sheet 7 for absorbing water from the cotton layer 1.

[0042] The absorbent sheet 7 is made of a superabsorbent polymer resin layer. One side of the absorbent sheet 7 is inserted into the bottom of the cavity 101. A connecting post 5 is fixedly connected to the bottom of the cavity 101. A guide hole 6 is opened in the middle of the connecting post 5. One end of the guide hole 6 is connected to the through hole 2. A slot 9 is opened on the side of the absorbent sheet 7 near the cavity 101 corresponding to the connecting post 5. The connecting post 5 is inserted into the slot 9 one by one. A cloth limiting plate 10 is fixedly connected to the port of the cavity 101. The limiting plate 10 is a rectangular ring structure. One edge of the absorbent sheet 7 is attached to the limiting plate 10. A raised strip 8 is integrally set on the side of the absorbent sheet 7 away from the slot 9. The raised strip 8 is exposed in the ring opening of the limiting plate 10 and is arranged in an arc-shaped strip structure so that the rectangular ring limiting plate 10 limits and fixes the absorbent sheet 7 in the cavity 101, thereby improving the structural stability.

[0043] A cavity 101 is opened on one side of the cotton layer 1, and a connecting post 5 with guide holes 6 and absorbent sheets 7 with slots 9 and protrusions 8 on both sides are used in the cavity 101. When there is a small amount of sweat liquid on the cotton layer 1, the cotton layer 1 guides the liquid into the absorbent sheet 7 through the through hole 2 and the connecting post with guide holes 6. The super absorbent polymer resin particles of the absorbent sheet 7 absorb and lock in the water, and the excess water is guided to the outside through the protrusions 8 of the absorbent sheet 7, increasing the surface area for air drying, thereby further improving the dryness performance of the cotton layer 1.

[0044] That is, by combining the breathable mesh upper 4 with a sweat-wicking unit, the breathability of the athletic shoe can be improved.

[0045] Example 2

[0046] Please see Figure 1 , Figure 7 and Figure 8 A breathable athletic shoe, comprising:

[0047] The upper 4 is a mesh-like openwork knitted structure, with a sweat-wicking unit on one side of the upper;

[0048] The sweat-wicking unit includes a cotton layer 1, which includes at least one layer. The upper surface is coated with a polyethylene glycol fatty acid ester layer. After reacting at a high temperature of 150°C for 120 seconds, the hydroxyl groups on the surface of the cotton layer 1 are esterified, and the surface hydrophilicity is reduced, forming a pure cotton spunlace nonwoven fabric layer with a hydroxyl esterified surface.

[0049] The surface of cotton layer 1 is also provided with a liquid-guiding structure that facilitates liquid penetration.

[0050] The liquid guiding structure has a cavity 101 on one side of the cotton layer 1. Through holes 2 are equally spaced on the strip of the cotton layer 1. The through holes 2 are set as a frustum structure. One end of the through hole 2 is connected to the cavity 101. A patch 3 is set on the edge of the cotton layer 1 near the cavity 101. The surface of the cotton layer 1 is sprayed with a polyethylene glycol fatty acid ester layer. The polyethylene glycol fatty acid ester layer is locally esterified and arranged on the cotton layer 1 by reacting at a high temperature of 150°C for 120 seconds.

[0051] It should be noted that in this embodiment 1, an opening is made on one side of the shoe upper 4 to accommodate the sweat-wicking unit. The edges of the patch 3 are sewn together with silk thread inside the opening to improve the sweat-wicking effect on the shoe upper 4.

[0052] Specifically, in this application, polyethylene glycol fatty acid ester is uniformly sprayed onto the surface of cotton layer 1. After reacting at 150°C for 120 seconds, the hydroxyl groups on the surface of the pure cotton spunlace nonwoven fabric of cotton layer 1 are esterified, resulting in a decrease in the hydrophilicity of cotton layer 1 and achieving a balance between hydrophilicity and hydrophobicity. Applying cotton layer 1 to the shoe upper 4 significantly improves dryness without affecting the skin-friendliness of cotton layer 1 against the foot, thus enhancing the dryness effect during use. Simultaneously, frustum-shaped through-holes 2 are formed on cotton layer 1, with the larger end of the through-hole 2 opening on the front side of cotton layer 1, allowing sweat to be more quickly directed to the outside through the through-holes 2.

[0053] The cavity 101 is equipped with a water-absorbing sheet 7 for absorbing water from the cotton layer 1.

[0054] The absorbent sheet 7 is made of a superabsorbent polymer resin layer. One side of the absorbent sheet 7 is inserted into the bottom of the cavity 101. A connecting post 5 is fixedly connected to the bottom of the cavity 101. A guide hole 6 is opened in the middle of the connecting post 5. One end of the guide hole 6 is connected to the through hole 2. A slot 9 is opened on the side of the absorbent sheet 7 near the cavity 101 corresponding to the connecting post 5. The connecting post 5 is inserted into the slot 9 one by one. A connecting strip 11 is integrally set on the other side of the absorbent sheet 7 corresponding to the slot 9. A connecting hole 12 for communication is opened between the connecting strip 11 and the slot 9. A water guide sheet 13 is integrally set on one end of each connecting strip 11. The water guide sheet 13 is set as a circular plate structure. A plastic film 14 is fixedly connected to the port of the cavity 101. A connecting hole 15 is opened on the film 14 corresponding to the connecting strip 11. The connecting strip 11 is inserted into the connecting hole 15 one by one. The film 14 isolates the absorbent sheet 7 and the water guide sheet 13.

[0055] A cavity 101 is opened on one side of the cotton layer 1. A connecting post 5 with guide holes 6 and absorbent sheets 7 with slots 9 and protrusions 8 on both sides are used in the cavity 101. When there is a small amount of sweat liquid on the cotton layer 1, the cotton layer 1 guides the liquid into the absorbent sheet 7 through the through hole 2 and the connecting post 5 with guide holes 6. The super absorbent polymer resin particles of the absorbent sheet 7 absorb and lock in the water. At the same time, a sheet-like film 14 is used to seal the bottom of the opening of the cavity 101, isolating and sealing the absorbent sheet 7 in the cavity 101. A second connecting hole 15 is opened in the film 14. A connecting strip 11 is set on one side of the water guide sheet 13 and passes through the second connecting hole 15 to connect the absorbent sheet 7. The film 14 isolates the absorbent sheet 7 and the water guide sheet 13, leaving the water guide sheet 13 exposed outside the cavity 101. This allows excess water in the absorbent sheet 7 to be guided to the outside for drying. During the process, the absorbent sheet 7 is limited and fixed in the cavity 101, which also improves the stability of the structure.

[0056] That is, by combining the breathable mesh upper 4 with a sweat-wicking unit, the breathability of the athletic shoe can be improved.

[0057] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
