Description

Technical Field

[0001] This invention relates to the field of functional textiles and sports protective equipment, specifically to a non-slip sports sock. Background Technology

[0002] Most existing sports socks are made of ordinary knitted materials, primarily focusing on moisture-wicking, foot conformation, and comfort. However, they are significantly lacking in anti-slip performance. Traditional sports socks have low interfacial friction with the insole, especially during high-intensity exercise. The foot is prone to sliding forward, backward, or laterally within the shoe, leading to reduced power transfer efficiency during push-off, affecting control and responsiveness, and increasing the risk of localized abrasion and blisters. Some products attempt to improve grip by adding rubber particles or localized coatings to the sock surface, but these structures are often limited to scattered distribution on the forefoot or heel, failing to systematically cover the main stress areas of the foot and lacking effective support for the area below the metatarsals and the toe flexion zone. This results in insufficient friction during push-off and poor stability. Particularly during golf swings or other sports, relative sliding between the foot and insole is common, especially on wet or sloping surfaces. Insufficient friction between ordinary socks and the sole reduces athlete stability, affecting accuracy and power transfer, ultimately lowering athletic performance.

[0003] Chinese patent CN219108755U discloses a breathable and non-slip sports sock, which includes a sock body comprising an upper, toe, sole, heel, leg opening, and ribbing. The sole has multiple anti-slip raised strips on its bottom surface, an arch support in the middle, and elastic bands on the upper and leg opening. This application enhances the anti-slip performance by increasing the frictional resistance between the sock and the shoe sole during exercise through the anti-slip raised strips on the sole. The arch support on the sole and the elastic bands on the upper and leg opening ensure a close fit to the foot, making the sock less likely to slip off or wrinkle. However, it still suffers from problems such as insufficient anti-slip performance and inadequate friction with the shoe sole leading to decreased athlete stability. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a non-slip sports sock, which solves the technical problem that existing sports socks cause a decrease in friction between the sock and the inside of the shoe due to sweating during high-intensity sports such as golf, which in turn leads to foot slippage and decreased body stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This application provides an anti-slip sports sock, including a sock body, the sock body including a sock sole, the sock sole being provided with an anti-slip layer, wherein the anti-slip layer at least covers the forefoot area, the toe flexion area and the heel area of ​​the sock sole, and the anti-slip layer covering the heel area of ​​the sock sole is symmetrically arranged along the center line of the length direction of the sock sole; The anti-slip layer comprises three layers, from the inside out: a reinforcement layer, a silicone base layer, and a silicone contact texture layer; The outer surface of the silicone contact texture layer in the forefoot area and toe flexion area of ​​the sock sole has multiple diamond-shaped protrusions; the outer surface of the silicone contact texture layer in the heel area of ​​the sock sole has multiple circular protrusions.

[0006] In some embodiments of this application, the extension direction of one side of the rhombus in the rhombus protrusion is at an angle of 45-60º to the center line of the length direction of the sock sole; the rhombus protrusions are arranged in an equally spaced array; one included angle of the rhombus in the rhombus protrusion is 60-120º; and the side length of the rhombus is 0.5-1.2 mm; and / or, The plurality of circular protrusions are arranged in concentric rings with the center of the heel area of ​​the sock sole as the center. The diameter of the circle of the circular protrusion is 0.2-0.4mm; the distance between adjacent circular protrusions is 0.3-0.6mm.

[0007] In some embodiments of this application, the thickness of the anti-slip layer is 0.8-3 mm, wherein the thickness of the reinforcing layer is 0.1-0.2 mm, the thickness of the silicone base layer is 0.5-2.4 mm, and the thickness of the silicone contact texture layer is 0.2-0.4 mm.

[0008] In some embodiments of this application, the reinforcing layer is made of nylon mesh or polyester fiber, wherein the edges of the reinforcing layer are beveled to form a transition zone with an inclination angle of 30-45º.

[0009] In some embodiments of this application, the top of the rhomboid protrusion and / or the circular protrusion is provided with a rounded chamfer, wherein the radius of curvature of the rounded chamfer is 0.05-0.15mm and the sidewall inclination angle is 70-85º.

[0010] In some embodiments of this application, the microchannel porosity of the outer surface of the silicone contact texture layer is 40% to 60%, and / or the microchannel width is distributed in the range of 0.08 mm to 0.25 mm.

[0011] In some embodiments of this application, the gaps between the rhomboid protrusions or circular protrusions form microchannels, and drainage holes are provided in the microchannels. The drainage holes penetrate the anti-slip layer to the surface of the sock sole, wherein the diameter of the drainage holes is 0.1mm-0.2mm.

[0012] In some embodiments of this application, the anti-slip layer also covers the arch area of ​​the sock sole, wherein the length of the anti-slip layer in the arch area is 25-35% of the total length of the sock sole, and / or the width of the anti-slip layer in the arch area is 20-40 mm.

[0013] In some embodiments of this application, the anti-slip layer is manufactured by a one-piece molding process.

[0014] In some embodiments of this application, the anti-slip sports socks are golf socks.

[0015] The beneficial effects of this invention are as follows: The structural design of this anti-slip sock avoids the slipping problem caused by traditional socks relying solely on the friction of the fabric surface. It is particularly suitable for sports such as golf and tennis, which require high stability of posture and precision of movement. Due to the high surface energy and viscoelastic properties of silicone material, it can generate a strong interfacial bonding force with common polyester, nylon, or EVA insoles, maintaining good anti-slip performance even in wet environments.

[0016] This application's anti-slip sports socks feature an anti-slip layer in the forefoot area that extends below the metatarsal bones and covers the toe flexion area. A symmetrical anti-slip layer along the center line of the sock's length is located in the heel area. Multiple diamond-shaped protrusions are present on the outer surface of the contact texture layer in the forefoot and toe flexion areas, and multiple circular protrusions are present on the outer surface of the contact texture layer in the heel area. Through this design, the anti-slip performance of this application's anti-slip sports socks is significantly improved, making them suitable for the anti-slip and shock-absorbing needs of high-intensity sports such as golf, thus enhancing the athlete's stability during exercise.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0025] In this application, "multiple" means two or more.

[0026] In one specific embodiment of this application, this application provides an anti-slip sports sock, including a sock body, the sock body including a sock sole 1, the sock sole being provided with an anti-slip layer, wherein the anti-slip layer at least covers the forefoot area, the toe flexion area and the heel area of ​​the sock sole, and the anti-slip layer covering the heel area of ​​the sock sole is symmetrically arranged along the center line of the length direction of the sock sole. The anti-slip layer comprises three layers, from the inside out: a reinforcing layer 100, a silicone base layer 200, and a silicone contact texture layer 300. The outer surface of the silicone contact texture layer in the forefoot area and the toe flexion area of ​​the sock sole has multiple diamond-shaped protrusions; the outer surface of the silicone contact texture layer in the heel area of ​​the sock sole has multiple circular protrusions.

[0027] In this application, the sole of the sock is divided into the toe area, the toe flexion area, the forefoot area, the arch area, and the heel area along the direction from the toe to the heel. Specifically, based on the total length of the sole, the toe area extends from the center of the toe to 5-10% of the total length of the sole; the toe flexion area extends from the toe to 15-25% of the total length of the sole; the forefoot area extends from the toe flexion area to 50-60% of the total length of the sole; the arch area extends from the forefoot area to 80-85% of the total length of the sole; and the heel area extends from the arch area to the center of the heel.

[0028] It should be noted that, in this application, the center of the sock toe refers to the midpoint of the sock toe. The center of the sock heel refers to the midpoint of the sock heel. The total length of the sock sole is the straight-line distance from the center of the sock to the center of the sock heel. In this application, the centerline of the sock sole's length direction refers to the straight line from the center of the sock to the center of the sock heel.

[0029] It is understood that the direction from the inside out in this application refers to the direction from the sole of the sock to the anti-slip layer. That is, the part where the anti-slip layer contacts the sole of the sock is the inside, that is, the reinforcing layer covers the sole of the sock, followed by the silicone base layer and the silicone contact texture layer in sequence.

[0030] Understandably, the forefoot area of ​​the sock sole is designed to cover the forefoot region of the foot, which refers to the area located at the front of the sole, below the metatarsal bones. This area is one of the main pressure-bearing parts of the body during standing and movement, especially responsible for propulsion in actions such as the golf swing. The anti-slip layer covering this area enhances friction and stability during push-off, preventing the foot from slipping inside the shoe.

[0031] Understandably, the toe flexion zone on the sole of the sock covers the toe flexion area of ​​the foot, which is the area where the front of the sole connects to the toes and is a key area for toe gripping and flexion. This area connects with the forefoot area to form a complete power band. The anti-slip layer extends to the toe flexion zone, providing continuous interfacial engagement force during the toe gripping phase, ensuring that the forefoot does not shift during twisting and propulsion.

[0032] Understandably, the heel area of ​​the sock sole is designed to cover the heel area of ​​the foot, which is the weight-bearing area of ​​the calcaneus at the back of the foot—the area where the calcaneus directly bears the body's weight. The anti-slip layer in this area is symmetrically arranged along the center line of the sock sole's length to evenly distribute pressure. Covering this area improves cushioning and anti-slip performance when the heel strikes the ground, inhibiting heel slippage or deflection and ensuring the stability of the lower limb kinetic chain.

[0033] Reference Figure 1 and Figure 2In this application, the surface of the sock sole 1 is provided with an anti-slip layer 130 for the forefoot area, an anti-slip layer 120 for the toe flexion area, and an anti-slip layer 150 for the heel area. These anti-slip layers are located between the sock sole and the insole, enhancing the friction between the foot and the insole and preventing relative slippage of the foot within the shoe during exercise. The anti-slip layers cover the forefoot and heel areas of the sock sole. These two areas are key areas that bear the main pressure during standing and walking, especially in movements requiring high stability, such as a golf swing. The forefoot is responsible for propulsion, while the heel serves as a pivot point for weight transfer and rotation. Therefore, providing anti-slip layers in these areas effectively improves the accuracy of movements and the efficiency of power transmission.

[0034] The forefoot anti-slip layer 130 on the sole of the sock extends along the lower part of the metatarsal bone, connecting with and covering the toe flexion area anti-slip layer 120. It maintains a stable fit with the insole during foot extension and flexion, preventing movement deformation due to localized slippage. The anti-slip layer in this area is structurally designed to be specifically adapted to the biomechanical characteristics of the foot, providing continuous interfacial gripping force during toe gripping, ensuring that the forefoot does not experience axial or tangential displacement during torsion and propulsion.

[0035] The anti-slip layer 150 of the heel area of ​​the sock sole covers the heel area and is symmetrical along the center line of the sock sole length, forming a uniform pressure distribution and anti-rotation support. This symmetrical layout helps maintain the static stability of the heel during the up-and-down phases, preventing deflection and slippage around the ankle joint when under unilateral force or in a sloping stance, thereby ensuring the continuity of the entire lower limb kinetic chain.

[0036] In the forefoot and toe flexion areas of the sock sole, the diamond-shaped protrusion 301 matches the pronation and supination shear directions of the forefoot during the swing, optimizing resistance to lateral slippage. In the heel area of ​​the sock sole, the circular protrusion 302 guides the dispersion of shear stress under rotational loading, improving axial stability.

[0037] Reference Figure 4In some embodiments of this application, the extension direction of one side of the rhombus in the rhombus protrusion is at a 45-60° angle to the center line of the sock's length direction. The rhombus protrusions are arranged in an equally spaced array, and one included angle of the rhombus in the rhombus protrusion is 60-120°, with a side length of 0.5-1.2 mm. In golf swings, tennis lateral movements, and other actions, the forefoot does not bear a single forward / backward or left / right force, but rather a complex oblique shear force. For example, when a right-handed player moves from the backswing to the downswing, their center of gravity shifts from the right foot to the left foot, accompanied by a torso rotation. This generates a shear force on the forefoot of the left foot pointing from the outer rear to the inner front, and vice versa on the forefoot of the right foot. Arranging the rhombus array at a 45-60° angle ensures that the sides of the rhombus form an optimal angle with the direction of these expected oblique shear forces. The rhombus itself possesses anisotropic frictional properties. When the array is arranged at an angle, the silicone texture provides effective resistance to both pronation (pronation) and supination (supination) of the foot. The angled diamond-shaped edges create an effective "locking" effect in the forward and backward direction. Similarly, these edges are also very effective at resisting lateral slippage. This angled arrangement achieves comprehensive suppression of multi-directional slippage, providing more comprehensive anti-slip performance than simple horizontal or vertical stripes.

[0038] Reference Figure 4 In some embodiments of this application, the plurality of circular protrusions 302 are arranged in a concentric array with the center of the heel area of ​​the sock sole as the center, and the diameter of the circular protrusion is 0.2-0.4mm; the spacing between adjacent circular protrusions is 0.3-0.6mm.

[0039] It is understandable that the center of the heel area on the sole of the sock is the pressure center of the heel area. When the human body is in a standard standing or athletic landing posture, the pressure center of the heel area, where the heel (calcaneus) contacts the supporting surface (insole), is the point where the combined force of the vertical stress (pressure) distribution on the sole of the foot acts. The distance between adjacent circular protrusions refers to the difference between the center distance between adjacent circular protrusions and the sum of the radii of the two adjacent circular protrusions.

[0040] When the heel strikes the ground, the pressure diffuses outwards from that point. Circular or spiral grooves centered on this point can follow the propagation path of the shock wave, effectively guiding and dispersing concentrated stress in all directions, preventing excessive local pressure and thus evenly distributing stress. In movements such as a golf swing, the heel may experience rotational torque. Concentric grooves provide uniform, isotropic shear resistance, offering stable anti-slip performance regardless of the direction of rotation—the so-called "guiding shear stress dispersion and improving axial stability."

[0041] Reference Figure 3In some embodiments of this application, the thickness of the anti-slip layer is 0.8-3 mm, wherein the thickness of the reinforcing layer is 0.1-0.2 mm, the silicone base layer is 0.5-2.4 mm, and the silicone contact texture layer is 0.2-0.4 mm. This thickness range has been verified by compression rebound testing, ensuring sufficient elastic deformation capacity while maintaining structural integrity. When the silicone base thickness is less than 0.5 mm, the silicone material is prone to fatigue cracking under repeated flexural loads, and it is difficult to achieve uniform coating, affecting adhesion reliability; while exceeding 3 mm will significantly increase the internal volume of the sock, interfering with the proprioceptive feedback of the foot and reducing the wearing fit. When the thickness of the anti-slip layer is 0.8-1.2 mm, this value achieves the best balance between functionality and comfort, suitable for high-frequency, low-amplitude dynamic friction scenarios, such as the rapid center of gravity shift during a golf swing. The silicone contact surface textured layer has a thickness of 0.2mm to 0.4mm and is mainly used to support the surface's uneven textured structure, achieving microscopic integration with the insole fibers. The base layer has a thickness of 0.5mm to 2.4mm and provides overall cushioning support and mechanical load-bearing capacity. In some embodiments, the height of the circular protrusions is 0.05-0.15mm. In some embodiments, the height of the diamond-shaped protrusions is 0.05-0.15mm.

[0042] In some embodiments of this application, the silicone substrate layer and the silicone contact texture layer are formed in one step through a co-vulcanization process, which allows the molecular chains to be fully cross-linked at the interface to form a continuous phase structure, significantly improving the interlayer bonding strength and preventing peeling during dynamic use.

[0043] In some embodiments of this application, the reinforcing layer is made of nylon mesh or polyester fiber.

[0044] The reinforcing layer is made of embedded nylon mesh or polyester fiber. This reinforcing layer serves as a mechanical reinforcement structure, improving the overall tensile strength and creep resistance of the anti-slip layer, particularly inhibiting material stretching and wrinkling deformation under severe foot torsion conditions. The reinforcing layer is a plain-weave nylon mesh or polyester fiber fabric with a warp and weft density of 30-50 threads / cm and a thickness of 0.1mm-0.2mm. It possesses moderate stiffness and flexibility, capable of stress transmission without affecting the sock's bending conformability. The reinforcing layer is located close to the base of the sock fabric, facilitating uniform stress diffusion and reducing interfacial stress concentration.

[0045] In some embodiments of this application, the edge of the reinforcing layer is beveled to form a transition zone with an angle of 30-45°, preferably with a length of 0.1-0.3 mm. This beveled transition structure can effectively alleviate stress concentration caused by abrupt changes in material stiffness, avoid crack initiation points in bending areas, and extend service life. The length of the transition zone is controlled within the range of 0.1 mm to 0.3 mm to ensure a smooth geometric transition.

[0046] In some embodiments of this application, the anti-slip layer is manufactured using a hot-press one-time molding process. This one-time molding process allows liquid silicone to fully impregnate the fiber gaps of the reinforcing layer, forming a mechanical anchoring structure. During the molding process, upper and lower molds are aligned and pressurized, with the temperature controlled at 120℃~150℃, the pressure range at 0.3MPa~0.6MPa, and the vulcanization time at 60s~120s. This ensures that the silicone completely penetrates the fabric pores and firmly bonds to the sock fabric substrate, achieving continuous, one-piece coverage and eliminating the risk of seam cracking that may occur with segmented bonding. The anti-slip layer is formed in one step during the liquid silicone vulcanization process using a high-precision steel mold. The mold cavity is modeled based on the three-dimensional curved surface of the foot, and the surface is treated with electrical discharge machining or laser etching, achieving a roughness Ra≤0.8μm, ensuring accurate replication of the micron-level texture and batch consistency. The silicone base layer and the silicone contact texture layer use addition-cure liquid silicone rubber with a Shore hardness of 40A~60A, an elongation ≥400%, and a tear strength ≥15kN / m. This material possesses excellent crosslinking density control properties, enabling high-fidelity replication of fine textures during vulcanization, while also exhibiting good aging resistance and resistance to environmental moisture erosion. During movement, this silicone rubber can rapidly recover its original shape under cyclic compression and shear loads, avoiding permanent deformation and ensuring consistent anti-slip performance over long-term use.

[0047] In some embodiments of this application, the tops of the rhomboid and / or circular protrusions are provided with rounded chamfer transitions, wherein the radius of curvature of the rounded chamfer is 0.05-0.15 mm, and the sidewall inclination angle of the rounded chamfer is 70-85°. Protrusion tops are provided with rounded chamfer transitions, with a radius of curvature of 0.05 mm to 0.15 mm, reducing the risk of fatigue crack initiation during cyclic friction and improving wear life. It should be noted that the sidewall inclination angle of the rounded chamfer refers to the angle between the sidewall surface of the rounded chamfer and the reference plane (the plane of the sock sole), used to describe the degree of inclination of the protrusion. The sidewall inclination angle of 70° to 85° forms a micro-wedge structure, which, when the foot is pressed vertically downwards, can embed into the polyester or nylon short fibers on the insole surface, producing a self-locking effect and significantly enhancing the interface's anti-slip capability.

[0048] See Figure 6In some embodiments of this application, the microchannel connectivity porosity of the outer surface of the silicone contact texture layer is 40% to 60%, and / or the microchannel width is distributed between 0.08 mm and 0.25 mm.

[0049] It should be noted that, in this application, the gaps between the rhomboid or circular protrusions constitute microchannels, as shown in the reference. Figure 4 and Figure 5 Microchannel porosity refers to the percentage of the volume of interconnected voids (i.e., gaps formed between protrusions, such as grooves and pits) in the textured area of ​​the silicone contact layer surface, relative to the total volume of the textured area. It does not refer to the density of the silicone material itself, but rather to the "openness" of the surface "pattern." A porosity of 40%-60% means that a small portion of the volume is empty, forming an interconnected network of grooves. High porosity ensures that sweat or water films can be quickly and laterally channeled through this network, rather than being trapped in isolated pits, thus maintaining a dry sock-shoe interface and preventing a decrease in friction due to moisture.

[0050] In this application, the microchannel width distribution refers to the range of widths of the interconnected microchannels mentioned above. It does not describe that all widths (or gaps) are the same size, but rather that they vary in size, forming a distribution. It's like a filter system with fine mesh (0.08mm) and slightly larger mesh (0.25mm). A suitable width distribution can efficiently handle different amounts of sweat. Smaller gaps generate stronger capillary forces for adsorbing and diffusing trace amounts of sweat; larger widths are used to quickly transport larger amounts of sweat, preventing channel saturation, and together optimizing overall moisture wicking efficiency.

[0051] In some embodiments of this application, the bottom of the microchannel (the gap between the protrusions, or microchannel) is provided with multiple drainage holes, the diameter of which is 0.1mm to 0.2mm, penetrating the anti-slip layer to the inner layer of the sock, enabling vertical drainage of liquid and preventing water accumulation to form a lubricating layer. The drainage holes are arranged in a non-uniform distribution, with a density of 8 to 12 holes / mm² in high-shear areas to enhance drainage efficiency; and reduced to 3 to 5 holes / mm² in low-stress areas to balance structural integrity and breathability. This drainage system achieves directional puncture molding through a locally perforated structure in the mold, ensuring precise penetration of the drainage channel without compromising overall sealing.

[0052] It should be noted that the division of the foot into zones is based on the force characteristics of the sole during movement. The high-shear zone refers to the area where strong relative sliding or torsional tendencies easily occur between the sole and the insole during movement. These areas primarily bear shear stress. Specifically, this mainly refers to the forefoot area (especially below the metatarsal heads): this is the main fulcrum for pushing off, generating force, and rotating, where shear forces are extremely high. The front outer area of ​​the heel: This area bears enormous impact and shear during landing and braking.

[0053] Higher pore density (8-12 pores / mm²) in these areas aims to provide maximum instantaneous drainage in key areas prone to frictional heat and sweat buildup, ensuring slip resistance. Low-stress zones refer to areas that are relatively stationary or have weak relative movement to the insole during exercise, experiencing lower shear stress. These typically include the middle of the arch area and non-core stress points on the forefoot and heel. These areas primarily provide support and transition, rather than active force application. Lowering the pore density (3-5 pores / mm²) in these areas prioritizes the structural integrity and overall strength of the silicone layer while maintaining adequate moisture wicking, avoiding excessive perforation that could weaken its support and durability.

[0054] Reference Figure 7 In some embodiments of this application, the anti-slip layer is provided in the arch area of ​​the sock sole. The arch is an arch-shaped structure in which the foot is suspended when not bearing weight. The anti-slip layer extends to cover the arch area, forming a continuous support band from the forefoot area through the arch area to the heel area. This continuous structure connects the originally separate forefoot and heel anti-slip areas into a unified mechanical system, which not only improves the structural integrity of the bottom of the sock, but also plays a synergistic shear-resistant role when the foot twists or exerts lateral force. Although the arch area does not directly bear the main weight load, as a transition section between the front and rear force areas, its protective layer helps to prevent local wrinkling deformation and stress concentration, and reduces the risk of material peeling caused by dynamic deformation.

[0055] Furthermore, the anti-slip layer is bonded to the fabric substrate of the sock body through a one-piece hot-press molding process. This process uses upper and lower molds to apply pressure, with the temperature controlled between 120℃ and 150℃, the pressure range between 0.3MPa and 0.6MPa, and the vulcanization time between 60s and 120s, ensuring that the liquid silicone is fully cross-linked and cured, achieving a stable bond with the sock fabric. One-piece molding avoids the seam cracking problems that may occur with segmented bonding, significantly improving product durability.

[0056] In this application, the one-piece hot-press molding process refers to treating the anti-slip layers of the forefoot area, toe flexion area, arch area, and heel area of ​​the sock sole as a whole, and then molding the reinforcing layer, silicone base layer, and silicone contact texture layer in one piece.

[0057] In some embodiments of this application, the anti-slip layer in the arch area extends for 25-35% of the total length of the sock sole, and / or has a width of 20-40 mm.

[0058] The anti-slip layer extends 25%–35% of the total foot length in the arch region, with a width of 20mm–40mm, adapting to adult arch curvature radii of 80mm–120mm. This size range is determined based on extensive foot type data analysis, ensuring compatibility with different foot arch curvatures and guaranteeing a snug fit between the silicone layer and the sole without any gaps or wrinkles during wear. The silicone layer in the arch region extends along the medial edge of the sole, starting 5mm behind the head of the first metatarsal and ending 8mm in front of the talus tuberosity, forming an arc-shaped biomechanical path running through the midfoot, precisely matching the pressure transmission trajectory during walking and swinging. This layout ensures functional continuity while avoiding excessive stretching that could affect the sock's flexibility.

[0059] The anti-slip layer exhibits a gradient thickness in the arch region, with the outer textured functional layer measuring 0.2mm–0.4mm and the inner elastic support layer ranging from 0.6mm to 2.6mm. These two layers are fused at the molecular chain level through a co-vulcanization process, achieving an interfacial shear strength ≥0.8MPa. This gradient structure design balances surface function with internal support: the textured functional layer bears the uneven texture to enhance interfacial friction, while the elastic support layer provides sufficient cushioning and rebound. During co-vulcanization, the inner and outer silicone materials undergo a cross-linking reaction under high temperature and pressure, forming a continuous three-dimensional network structure. This ensures that the interfacial bonding strength approaches the strength of the bulk material, eliminating the risk of delamination. This structure also accommodates subsequent reinforcement layer embedding processes, laying the foundation for optimizing overall mechanical properties.

[0060] In some embodiments of this application, the anti-slip sports socks may be golf socks. Example

[0061] like Figures 1-6 As shown, this embodiment provides an anti-slip sports sock, including a sock body, which includes a sock sole 1 and a sock leg 2. The sock sole 1 is divided into a sock sole toe area 11, a sock sole toe flexion area 12, a sock sole forefoot area 13, a sock sole arch area 14, and a sock sole heel area 15. The sock sole toe area is located at 7% of the total length from the center of the sock toe to the sock sole; the sock sole toe flexion area is located at 17% of the total length from the sock sole to the sock sole; the sock sole forefoot area is located at 50% of the total length from the sock sole to the sock sole; the sock sole arch area is located at 80% of the total length from the sock sole forefoot to the sock sole; and the sock sole heel area is located from the sock sole arch area to the center of the sock heel.

The anti-slip layer 150 covering the heel area is symmetrically arranged along the center line 16 of the sock sole length. The anti-slip layers have the same structure and each includes three layers, from the inside out: a reinforcing layer 100, a silicone base layer 200, and a silicone contact texture layer 300. The reinforcing layer is made of polyester fiber and has a thickness of 0.1 mm. The silicone base layer and the silicone contact texture layer are made of silicone, with the silicone base layer having a thickness of 0.9 mm and the silicone contact texture layer having a thickness of 0.2 mm.

[0063] like Figure 4 In the forefoot area and toe flexion area of ​​the sock sole, the outer surface of the silicone contact texture layer 300 is provided with multiple diamond-shaped protrusions 301.

The height of the diamond-shaped protrusion is 0.1 mm, the included angle of one of the diamonds is 90°, the side length is 1 mm, and the edge of one of the diamonds forms a 45° angle with the center line 16 of the sock sole length direction. The diamond-shaped protrusions are arranged in an equally spaced array, the center distance between two adjacent diamond-shaped protrusions is 1.5 mm, and the microchannel connectivity porosity is 55.5%.

[0064] like Figure 5 As shown, in the heel area of ​​the sock sole, the outer surface of the silicone contact texture layer 300 has multiple circular protrusions 302, and the gaps between the circular protrusions form a second microchannel 304.

The height of each circular protrusion is 0.1 mm, the diameter of each circular protrusion is 0.4 mm, and there are 30 concentric rings with radii of 0.5 mm, 1 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, 6.0 mm, 6.5 mm, and 7 mm respectively. 0mm, 7.5mm, 8.0mm, 8.5mm, 9.0mm, 9.5mm, 10.0mm, 10.5mm, 11.0mm, 11.5mm, 12.0mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm. The axial spacing (distance between the centers of the two circles) of the circular protrusions on the same ring is equal. Following the order from the inside out, the axial spacing of the circular protrusions on the concentric rings are respectively... The microchannel porosity is approximately 0.63 mm, 0.63 mm, 0.59 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, 0.60 mm, and 0.60 mm, with a microchannel connectivity porosity of 57.9%.

[0065] like Figure 6 As shown, multiple first drainage holes 305 with a diameter of 0.1 mm are opened at the bottom of the first microchannel; wherein, the first drainage holes 305 penetrate the anti-slip layer to the surface of the sock sole.

[0066] Reinforcing layers are laid on the forefoot area 11, toe flexion area 12 and heel area 13 of the sock sole, and then placed into the lower mold. Liquid rubber is added to the lower mold, and the upper and lower molds are put together and pressed. The pressure is controlled at 0.3MPa and the temperature is controlled at 130℃. The sock is heated and vulcanized for 100s to obtain the above-mentioned sports anti-slip socks with anti-slip layer.
