Description

Technical Field

[0001] This invention relates to the field of health care products, and more particularly to a toe cover with drainage and moisture-wicking function. Background Technology

[0002] The constant dampness and lack of ventilation between the toes can easily lead to fungal growth, causing foot problems such as athlete's foot and maceration. To address this issue, silicone toe separators have been developed to physically separate the toes. However, silicone is rigid, has poor breathability, and can cause skin discomfort with prolonged wear, and it also easily harbors bacteria. Furthermore, while medicated foot care products (such as antifungal creams and sprays) have some therapeutic effect, they are highly addictive, have side effects, and cannot provide continuous daily preventative care.

[0003] A search of existing technologies revealed that Chinese patent application CN200910067847.0 discloses a "single toe sleeve," which is a tubular fabric, entirely or partially made of antibacterial yarn, with radial elasticity, a circumferential length of 20-60mm, and an axial length of 10-50mm. This solution mainly relies on antibacterial yarn to achieve odor prevention;

[0004] Chinese utility model patent CN212545647U discloses an "odor-proof toe cover", which includes a strip of cloth made of antibacterial and deodorizing elastic fabric, and the strip of cloth has at least one toe perforation.

[0005] However, existing toe covers have poor sweat absorption speed, and sweat easily seeps back in, making it difficult to keep the toes dry. Sweat does not evaporate quickly to the outside, resulting in localized dampness on the toes. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing toe covers, such as poor sweat absorption, easy backflow of sweat, difficulty in keeping toes dry, and difficulty in quickly evaporating sweat to the outside, resulting in localized dampness on the toes. Therefore, this invention proposes a toe cover with drainage and moisture-wicking functions.

[0007] This invention provides a toe cover with drainage and moisture-wicking function, comprising a toe cover assembly, wherein the toe cover assembly includes a one-way moisture-wicking layer;

[0008] The one-way moisture-wicking layer includes a hydrophobic inner layer and a hydrophilic outer layer. The one-way moisture-wicking layer is located on the inside of the toe sleeve, corresponding to the area between the toes. The hydrophobic inner layer and the hydrophilic outer layer form a differential capillary effect to conduct sweat unidirectionally from the toe gaps outward.

[0009] The toe cover also includes a water-absorbing and evaporating layer, which is located on the outside of the toe cover in the area corresponding to the toe crease and the outer periphery of the toes. The water-absorbing and evaporating layer is made of a fluffy fabric with moisture-absorbing and breathable properties.

[0010] Preferably, the hydrophobic fiber inner layer is woven from hydrophobic polypropylene filaments.

[0011] Preferably, the hydrophilic fiber outer layer is woven from hydrophilic yarn.

[0012] Preferably, the fluffy fabric is terry cloth.

[0013] Preferably, the one-way moisture-wicking layer and the water-absorbing and evaporating layer are joined together by ultrasonic spot welding, hot pressing, sewing, or adhesive bonding.

[0014] Preferably, the toe sleeve is cylindrical in shape and is worn around the base of the toes.

[0015] Preferably, the hydrophobic fiber inner layer and the hydrophilic fiber outer layer are integrally formed by knitting or weaving.

[0016] Preferably, the plurality of toe sleeves are worn on the toes individually.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the composite structure of a hydrophobic inner layer and a hydrophilic outer layer, a differential capillary effect is created by utilizing the ≥12% difference in moisture regain between the two layers, achieving unidirectional sweat wicking, preventing sweat backflow, and keeping the spaces between the toes dry. The unidirectional moisture-wicking layer of this invention has a unidirectional transfer index O≥100, and its moisture absorption and wicking performance reaches level 3 or above, exhibiting excellent unidirectional liquid water transfer performance.

[0019] 2. The absorbent and volatile layer made of fluffy fabric has high moisture absorption and breathability, with a drying rate ≥0.20g / h, moisture permeability ≥8000g / (m²·24h), and air permeability of 100-500mm / s. It can quickly absorb sweat and evaporate it to the outside, preventing local dampness.

[0020] 3. The entire structure is made of flexible fabric, which is soft and comfortable, can be worn continuously every day, and has good breathability. It is not easy to breed bacteria. It works purely physically, does not rely on drugs, has no side effects, and is suitable for daily prevention and care for people susceptible to athlete's foot. The structure is simple, the cost is low, and it is suitable for large-scale production. Attached Figure Description

[0025] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] like Figs. 1 to 3 The toe cover shown has a drainage and moisture-wicking function, including a toe cover whole 1, and the toe cover whole 1 includes a one-way moisture-wicking layer 2.

[0027] The one-way moisture-wicking layer 2 includes a hydrophobic fiber inner layer 21 and a hydrophilic fiber outer layer 22. The one-way moisture-wicking layer 2 is located on the inside of the toe sleeve, corresponding to the area between the toes. The standard moisture regain of the hydrophobic fiber inner layer 21 is 0%-0.5%, and the standard moisture regain of the hydrophilic fiber outer layer 22 is 8.5%-13%. The difference in moisture regain between the two is ≥8%. The one-way transfer index O of the one-way moisture-wicking layer 2 is ≥100, the water absorption rate is ≥80%, the drip diffusion time is ≤6 seconds, and the wicking height is ≥80mm. The hydrophobic fiber inner layer 21 and the hydrophilic fiber outer layer 22 form a differential capillary effect to conduct sweat unidirectionally from the toe gaps to the outside.

[0028] The toe cover as a whole 1 also includes a water-absorbing and evaporating layer 3, which is located on the outside of the toe cover in the area corresponding to the toe gaps and the outer periphery of the toes. The water-absorbing and evaporating layer 3 is made of a fluffy fabric with moisture-absorbing and breathable properties. The drying rate of the water-absorbing and evaporating layer 3 is ≥0.20g / h, the moisture permeability is ≥8000g / (m²·24h), the air permeability is 100-500mm / s, and the porosity is 60%-85%.

[0029] Existing toe covers have poor sweat absorption speed, and sweat easily seeps back in, making it difficult to keep toes dry. Sweat does not evaporate quickly to the outside, resulting in dampness in the toes.

[0030] This embodiment of the invention can solve the above problems. The specific implementation method is as follows: through the composite structure of hydrophobic fiber inner layer 21 and hydrophilic fiber outer layer 22, the differential capillary effect is formed by the difference in moisture regain of ≥12% between the two, realizing the one-way export of sweat, avoiding sweat back seepage, and keeping the toe gaps dry. The one-way moisture-wicking layer 2 of the present invention has a one-way transfer index O≥100, and the moisture absorption and sweat wicking performance reaches level 3 or above, with excellent one-way liquid water transfer performance. The water-absorbing and volatile layer 3 composed of fluffy structure fabric has high moisture absorption and breathability, drying rate ≥0.20g / h, moisture permeability ≥8000g / (m²·24h), and air permeability of 100-500mm / s, which can quickly absorb sweat and evaporate it to the outside, preventing local dampness.

[0031] As an optional embodiment, the hydrophobic fiber inner layer 21 is woven from hydrophobic polypropylene filaments, with a standard moisture regain of 0% for polypropylene, 0.4%-0.5% for polyester, and 0.4%-0.5% for Coolmax profiled polyester fiber. The hydrophobic fiber inner layer 21 can be replaced with one of polyester, Coolmax, and nylon, and can be composed of a combination of polypropylene, polyester, Coolmax, and nylon.

[0032] As an optional embodiment, the hydrophilic fiber outer layer 22 is woven from hydrophilic yarn. The hydrophilic fiber outer layer 22 can be replaced with one of bamboo fiber, cotton fiber, Tencel and wool, or it can be composed of a combination of modal, bamboo fiber, cotton fiber, Tencel and wool. The standard moisture regain of modal fiber is 13%, the standard moisture regain of bamboo pulp fiber is 13%, the standard moisture regain of cotton fiber is 8.5%, and the standard moisture regain of lyocell fiber is 13%.

[0033] As an optional embodiment, the fluffy structure fabric is a terry cloth with a porosity of 65%-80% and an air permeability of 200-400 mm / s; the three-dimensional warp-knitted spacer fabric has a porosity of 70%-85% and an air permeability of 300-500 mm / s. The fluffy structure fabric can be replaced by one of the following: three-dimensional warp-knitted spacer fabric, sponge-like nonwoven fabric, or pile fabric; or the fluffy structure fabric is a combination of terry cloth, three-dimensional warp-knitted spacer fabric, sponge-like nonwoven fabric, and pile fabric.

[0034] As an optional embodiment, the one-way moisture-wicking layer 2 and the water-absorbing and evaporating layer 3 are joined together by ultrasonic spot welding, hot pressing, sewing or adhesive bonding.

[0035] As an optional embodiment, the toe sleeve 1 is cylindrical in shape and is worn around the base of the toes.

[0036] As an optional embodiment, the hydrophobic fiber inner layer 21 and the hydrophilic fiber outer layer 22 are integrally formed by knitting or weaving.

[0037] As an optional embodiment, multiple toe sleeves 1 are worn on the toes respectively. When in use, the toe sleeves are placed at the base of the toes, and the toe sleeves 1 are connected by flexible connecting straps. This multi-toe application structure can solve the problem of moisture wicking and drying between all toes at the same time, making it more convenient to use. The sweat between the toes is first absorbed by the inner layer of the one-way moisture-wicking layer 2 and conducted to the outer layer, and then absorbed by the outer water-absorbing evaporating layer and quickly evaporated into the air, thereby keeping the toe gaps dry for a long time.

[0038] As an optional embodiment, the hydrophobic fiber inner layer 21 is made of Coolmax irregular cross-section polyester fiber with a standard moisture regain of 0.4%-0.5%. The Coolmax fiber cross-section is a unique flat cross shape with four longitudinal grooves on the surface. Its specific surface area is 20% larger than that of a conventional circular cross-section, and its perspiration performance is higher than that of conventional polyester. The hydrophilic fiber outer layer 22 is made of bamboo fiber with a standard moisture regain of 13%. The water-absorbing and volatile layer 3 is made of three-dimensional warp-knitted spacer fabric. This fabric has a hollow and fluffy structure with a porosity of 70%-85% and an air permeability of 300-500 mm / s, providing better breathability. The layers are connected by hot-melt adhesive mesh through hot-pressing composite bonding. According to the test, the unidirectional transfer index of the unidirectional moisture-wicking layer 2 in this embodiment can reach level 5, which has a very good unidirectional sweat wicking effect.

[0039] As an optional embodiment, the toe sleeve 1 is semi-cylindrical in shape, only covering the base of the toes and the area between the toes, without covering the tips of the toes. The one-way moisture-wicking layer 2 and the water-absorbing and volatile layer 3 are cut according to ergonomics and then formed into a circumferentially closed structure by ultrasonic welding.

[0040] The toe sleeve of this invention can be manufactured using the following steps:

[0041] Step 1: Weave the fabrics of the one-way moisture-wicking layer 2 and the water-absorbing and evaporating layer 3 respectively;

[0042] Step 2: Align and stack the one-way moisture-wicking layer 2 and the water-absorbing and evaporating layer 3.

[0043] Step 3: The two layers are bonded together by ultrasonic intermittent spot welding, hot pressing, or sewing.

[0044] Step four: Cut and sew or weld the toe sleeves to the desired shape.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
