Description

Technical Field

[0001] This utility model relates to the field of running shoe fabric technology, and in particular to an outdoor ultralight running shoe fabric with a water-repellent coating. Background Technology

[0002] Outdoor running often involves encountering variable natural environments such as low temperatures, dampness, and wind and rain, which places stringent demands on the lightweight, functionality, and wearing experience of footwear materials. On the one hand, rain and dew in the outdoor environment can easily penetrate the shoe upper, leading to a damp and stuffy interior, which not only affects running comfort but may also cause foot discomfort. On the other hand, the feet bear continuous force during running, requiring the fabric to have sufficient support to maintain foot stability, while also having good cushioning to absorb the impact of landing and reduce the risk of sports injuries to joints such as the ankles and knees.

[0003] Existing outdoor running shoe fabrics have significant shortcomings in meeting these needs. Some products use high-weight coatings or thick waterproof membranes to improve water repellency. While these can block water, they significantly sacrifice the breathability and lightweight properties of the fabric, making it difficult for sweaty feet to dissipate heat and increasing the burden of running.

[0004] Other products focus on lightweight and breathability, using a single thin mesh material. However, due to the lack of effective support structure and cushioning design, they cannot meet the mechanical requirements of long-distance outdoor running, which can easily lead to foot fatigue or insufficient support, making it difficult to ensure foot stability and joint safety during exercise.

[0005] Furthermore, in low-temperature outdoor environments, most fabrics lack sufficient warmth retention, failing to provide adequate temperature protection for the feet and further limiting the product's applicability. Therefore, developing an outdoor running shoe fabric that integrates water repellency, breathability, ultralightness, support, cushioning, and warmth has become crucial to overcoming existing technological bottlenecks. Utility Model Content

[0006] To overcome the technical defects of the existing technology, this utility model provides an outdoor ultralight running shoe fabric with a water-repellent coating.

[0007] The technical solution adopted by this utility model is as follows: it includes a water-repellent coating, a breathable layer, a base structure layer, a support layer, and a buffer layer arranged sequentially from top to bottom.

[0008] Preferably, the water-repellent coating is a fluoropolymer nano-coating with a thickness of 5-15 μm. Fluoropolymers have excellent water-repellent properties, and the nano-level coating can form a uniform water-repellent film on the fabric surface, causing water droplets to roll off the fabric surface and effectively preventing moisture penetration. At the same time, the nano-coating is thin, so it will not significantly increase the weight of the fabric, nor will it have an excessive impact on breathability.

[0009] Preferably, the base structure layer is woven from a blend of nylon and polyester fibers, wherein nylon fibers account for 60%-70% and polyester fibers account for 30%-40%. Nylon fibers have high strength and abrasion resistance, while polyester fibers have good wrinkle resistance and dimensional stability. The blend of the two allows the base structure layer to possess both high strength and good morphological stability. The weaving process employs seamless three-dimensional weaving with a weaving density of 200-300 threads / inch. Seamless three-dimensional weaving reduces fabric seams, improving wearing comfort. Simultaneously, the three-dimensional weaving structure enhances the fabric's breathability and elasticity. The optimized weaving density further reduces weight while maintaining strength.

[0010] Preferably, the breathable layer is composed of a multi-layer fly-knitted mesh fabric and MONO yarn, wherein the porosity of the multi-layer fly-knitted mesh fabric is 40%-50%, the diameter of the MONO yarn is 0.08-0.12mm, and the thickness of the breathable layer is 0.3-0.5mm. The multi-layer fly-knitted mesh fabric has a rich porous structure, which can form effective air circulation channels. The MONO yarn has fine and tough characteristics. When combined with the multi-layer fly-knitted mesh fabric, it can not only ensure the breathability of the breathable layer, but also improve its structural strength, preventing the breathable layer from being easily damaged during use.

[0011] Preferably, the support layer is made of thermoplastic polyurethane (TPU) material, with thickened structures in the toe, heel, and arch areas. The thickness of the thickened areas is 1.2-1.8 mm, and the thickness of the non-thickened areas is 0.8-1.0 mm. The surface of the support layer has honeycomb-shaped grooves. TPU material has good hardness and toughness, providing stable support for the foot. The toe, heel, and arch are key areas of the foot that require support; the thickened structure enhances the support performance in these areas, while the non-thickened areas reduce weight while maintaining support. The honeycomb grooves not only further reduce weight but also enhance the breathability of the support layer.

[0012] Preferably, the cushioning layer is made of supercritical foamed PEBA material with a density of 0.1-0.15 g / cm³, an arched three-dimensional cushioning structure, and a thickness of 2-3 mm. Supercritical foamed PEBA material is ultra-lightweight and highly elastic; its low density effectively reduces fabric weight, while its high elasticity provides excellent cushioning performance. The arched three-dimensional cushioning structure increases the contact area with the foot, better absorbing the impact of landing during running and reducing pressure on the joints.

[0013] Preferably, the layers are bonded together using a hot melt adhesive film. The thickness of the hot melt adhesive film is 0.05-0.1 mm, the bonding temperature is 120-140℃, and the bonding pressure is 0.3-0.5 MPa. This hot melt adhesive film bonding method offers advantages such as strong adhesion and simple processing. Appropriate hot melt adhesive film thickness, bonding temperature, and pressure ensure the bonding strength between layers while preventing the film from being too thick and affecting the fabric's breathability and flexibility. The beneficial effects of this utility model are: 1. Excellent water-repellent performance: The fluoropolymer nano-coating effectively prevents water penetration and keeps the inside of the shoe dry, making it suitable for outdoor running in the rain.

[0014] 2. Excellent breathability: The breathable layer uses a multi-layer fly-knitted mesh and MONO yarn composite structure, combined with the honeycomb grooves of the support layer, which can form an effective air circulation and prevent the feet from getting stuffy and sweaty.

[0015] 3. Significantly lightweight characteristics: All layers are made of lightweight materials, such as supercritical foamed PEBA cushioning layer and thin hot melt adhesive film. Through structural optimization, such as the thickened area design of the support layer and the three-dimensional structure of the cushioning layer, the weight of the fabric is reduced to the maximum extent while ensuring performance.

[0016] 4. Excellent support and cushioning performance: The TPU support layer provides stable support for the feet and prevents sports injuries; the three-dimensional cushioning structure of the supercritical foamed PEBA cushioning layer can effectively absorb the impact force of landing, reduce the pressure on the joints, and improve running comfort.

[0017] 5. Overall performance balance: The various layers of the structure work together to achieve a good balance between water repellency, breathability, ultralightness, support and cushioning, which can meet the various complex needs of outdoor running. Attached Figure Description
