Description

Technical Field

[0001] This utility model relates to the field of protective fabric technology, specifically a weft-knitted protective fabric that combines skin-friendly comfort and abrasion resistance. Background Technology

[0002] In fields such as industrial production, outdoor sports, and military and police protection, protective fabrics are key materials for ensuring personnel safety and operational efficiency, with their core requirements focusing on abrasion resistance and comfort.

[0003] However, traditional abrasion-resistant protective fabrics are mostly made of woven or coated fabrics. Woven fabrics have a tight structure and good abrasion resistance, but poor elasticity, which restricts movement when worn. On the other hand, highly elastic knitted fabrics usually lack abrasion resistance and cannot meet the needs of long-term friction scenarios. Furthermore, in order to improve abrasion resistance, some fabrics are excessively thickened or use high-hardness fibers, which leads to a decrease in breathability and moisture permeability, making them stuffy and uncomfortable to wear.

[0004] In view of this, we will study and improve the existing protective fabric structure and its shortcomings, and provide a weft-knitted protective fabric that is both skin-friendly and comfortable as well as wear-resistant, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a weft-knitted protective fabric that combines skin-friendly comfort and abrasion resistance, in order to solve the problem mentioned in the background art that traditional abrasion-resistant protective fabrics mostly use woven or coated fabrics.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A weft-knitted protective fabric that combines skin-friendly comfort and abrasion resistance includes a protective fabric body. The protective fabric body includes a skin-friendly base layer, a cushioning intermediate layer, and an abrasion-resistant surface layer. The cushioning intermediate layer is disposed on the upper end of the skin-friendly base layer, and the abrasion-resistant surface layer is disposed on the upper end of the cushioning intermediate layer. The skin-friendly base layer is a plain knit weave of combed cotton and Modal fiber blend. The cushioning intermediate layer is a weft-knitted three-dimensional spaced weave of polyester fiber and nylon. The abrasion-resistant surface layer is a double rib weave of UHMWPE (ultra-high molecular weight polyethylene) and aramid fiber blend.

[0007] Furthermore, the UHMWPE content is 30-40 wt%, and the aramid fiber content is 60-70 wt%.

[0008] The beneficial effect of adopting the above-mentioned further scheme is that the ratio of 30-40 wt% UHMWPE content to 60-70 wt% aramid fiber content in the abrasion-resistant surface layer can achieve complementary performance. UHMWPE can significantly improve the tensile strength and rigidity of the fabric and enhance its impact resistance; while aramid fiber, with its excellent abrasion resistance and cut resistance, strengthens the abrasion resistance of the fabric surface, avoiding the fabric being too hard or too soft due to an excessive proportion of a single fiber, balancing abrasion resistance and wearing comfort, and ensuring that the fabric is not easily damaged during long-term friction use.

[0009] Furthermore, the UHMWPE is a short-cut UHMWPE with a surface modified by silane coupling agent KH-550, the length of the UHMWPE is 3-5 mm, and the diameter of the single filament of the UHMWPE is 7-10 μm.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the short-cut UHMWPE modified with silane coupling agent KH-550 can enhance the interfacial bonding force between UHMWPE and aramid fibers, prevent the fibers from falling off during blending or use, and improve the structural stability of the fabric surface.

[0011] Furthermore, the thickness of the wear-resistant surface layer is 0.8–1.5 mm.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the wear-resistant surface layer with a thickness of 0.8 to 1.5 mm can ensure that the surface layer has sufficient wear resistance and impact resistance to effectively resist external friction and minor impacts, while avoiding the overall heaviness and stiffness of the fabric due to excessive thickness. This ensures that the fabric maintains good flexibility and fit, making it suitable for clothing, protective gear, and other scenarios that require flexible wearing.

[0013] Furthermore, the thickness of the buffer intermediate layer is 0.5 to 1.2 mm, the nylon is high-elastic nylon yarn DTY, and the nylon content is 15 to 20 wt%.

[0014] The beneficial effects of adopting the above-mentioned further solutions are that the weft-knitted three-dimensional interval structure of the buffer intermediate layer has stable three-dimensional support and excellent resilience. The thickness of 0.5 to 1.2 mm ensures sufficient buffer space while avoiding the overall thickness of the fabric being too thick. The nylon high-elastic yarn DTY used has high strength, excellent elasticity and durable recovery, ensuring that the fabric has both excellent cushioning protection performance and wearing comfort during long-term use.

[0015] Furthermore, the polyester fiber is a 75D / 36F low-elasticity yarn, and the bulkiness of the weft-knitted three-dimensional interleaved structure of the polyester fiber and nylon is 30-40%.

[0016] The beneficial effects of adopting the above-mentioned further solutions are that the 75D / 36F low-elasticity polyester fiber, with its fine and elastic monofilaments, combined with the unique hollow three-dimensional structure of the weft-knitted three-dimensional spacer fabric and the high elasticity of nylon high-elasticity yarn DTY, endows the buffer layer with higher structural stability and fluffy characteristics; the 30-40% loft can effectively store more air, significantly improving the energy absorption effect of the buffer layer and enhancing its ability to absorb and disperse external impact forces; at the same time, the introduction of nylon high-elasticity yarn DTY further enhances the fatigue resistance of the spacer fabric, enabling the buffer layer to maintain excellent fluffy performance and buffering effect after long-term and repeated stress, avoiding a decrease in protective performance due to structural collapse.

[0017] Furthermore, the blending ratio of the combed cotton to Modal fiber is 6:4.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the 6:4 blend ratio of combed cotton and Modal fiber can give full play to the advantages of both fibers. Combed cotton can ensure the softness, breathability and moisture-wicking properties of the skin-friendly base layer, reducing the feeling of stuffiness on the skin; Modal fiber can improve the smoothness, luster and wrinkle resistance of the fabric, prevent the fabric from pilling or deforming after wearing for a long time, and balance the skin-friendly comfort and fabric durability, making it suitable for use in close-fitting protective scenarios.

[0019] Furthermore, it also includes a reinforcing mesh layer, which is disposed between the buffer intermediate layer and the skin-friendly base layer, and the reinforcing mesh layer is a polyester mesh fabric.

[0020] The beneficial effects of adopting the above-mentioned further solution are that the polyester mesh reinforcement layer set between the buffer intermediate layer and the skin-friendly base layer can enhance the bonding force between the two layers, prevent the fabric layers from separating, and improve the overall structural stability of the protective fabric body; the polyester material has high strength and wear resistance, which can further improve the tear resistance of the fabric, while the breathable structure of the mesh fabric will not affect the moisture absorption and breathability of the skin-friendly base layer, avoiding the fabric from becoming stuffy due to the addition of the reinforcement mesh layer, thus balancing structural strength and wearing comfort.

[0021] Compared with the prior art, the beneficial effects of this utility model are: This weft-knitted protective fabric combines skin-friendly comfort with abrasion resistance. The fabric itself utilizes a three-layer structure to achieve comprehensive protection: skin-friendly, cushioning, and abrasion-resistant. The skin-friendly base layer is a plain knit weave of combed cotton and Modal fibers, combining the softness and breathability of combed cotton with the smooth, skin-friendly properties of Modal fibers, enhancing comfort against the skin and reducing discomfort during prolonged wear. The cushioning middle layer is a three-dimensional weft-knit weave of polyester and nylon, utilizing the unique hollow structure of the three-dimensional weave to absorb external impact and provide cushioning protection. Nylon also gives the fabric good resilience, ensuring it doesn't easily deform after stretching. The abrasion-resistant surface layer uses a double rib weave of UHMWPE and aramid fibers. The high strength of UHMWPE combined with the abrasion resistance of aramid fibers significantly improves the fabric's surface abrasion resistance and tear resistance. The double rib weave further enhances the stability of the surface structure, making it suitable for outdoor work, sports protection, and other high-friction scenarios, extending the fabric's lifespan.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a weft-knitted protective fabric that combines skin-friendly comfort and abrasion resistance, including a protective fabric body 1. The protective fabric body 1 includes a skin-friendly base layer 101, a cushioning intermediate layer 102, and an abrasion-resistant surface layer 103. The cushioning intermediate layer 102 is provided at the upper end of the skin-friendly base layer 101, and the abrasion-resistant surface layer 103 is provided at the upper end of the cushioning intermediate layer 102. The skin-friendly base layer 101 is a plain knit structure made of combed cotton and Modal fiber blend, the cushioning intermediate layer 102 is a weft-knitted three-dimensional spaced structure made of polyester fiber and nylon, and the abrasion-resistant surface layer 103 is a double rib structure made of UHMWPE and aramid fiber blend.

[0028] As one embodiment of this utility model, the UHMWPE content is 30-40 wt%, and the aramid fiber content is 60-70 wt%. The ratio of 30-40 wt% UHMWPE content to 60-70 wt% aramid fiber content in the wear-resistant surface layer 103 can achieve complementary performance. UHMWPE can significantly improve the tensile strength and rigidity of the fabric and enhance its impact resistance. Aramid fiber, with its excellent wear resistance and cut resistance, strengthens the wear resistance of the fabric surface, avoiding the fabric being too hard or too soft due to an excessively high proportion of a single fiber. This balances wear resistance and wearing comfort, ensuring that the fabric is not easily damaged during long-term friction use.

[0029] As an embodiment of this utility model, the UHMWPE is further modified with silane coupling agent KH-550, which is a short-cut UHMWPE with a length of 3-5 mm and a single filament diameter of 7-10 μm. The short-cut UHMWPE modified with silane coupling agent KH-550 can enhance the interfacial bonding force between UHMWPE and aramid fiber, prevent the fiber from falling off during blending or use, and improve the structural stability of the fabric surface.

[0030] As one embodiment of this utility model, the thickness of the wear-resistant surface layer 103 is further 0.8 to 1.5 mm. The thickness of the wear-resistant surface layer 103 is 0.8 to 1.5 mm, which can ensure that the surface layer has sufficient wear resistance and impact resistance to effectively resist external friction and minor impacts, while not causing the fabric to be too heavy and stiff due to excessive thickness. This ensures that the fabric maintains good flexibility and fit, and is suitable for clothing, protective gear and other scenarios that require flexible wearing.

[0031] As one embodiment of this utility model, the thickness of the buffer intermediate layer 102 is further 0.5-1.2mm, the nylon is nylon high elastic yarn DTY, the nylon content is 15-20wt%, and the thickness of the buffer intermediate layer 102 is 0.5-1.2mm. This ensures that the air layer structure has sufficient buffer space while avoiding the overall fabric from being too thick. The nylon high elastic yarn DTY has a moderate thickness and a high elastic recovery rate, ensuring that the fabric has both buffer protection and wearing comfort.

[0032] As one embodiment of this utility model, the polyester fiber is further described as 75D / 36F low-elasticity yarn. The bulkiness of the weft-knitted three-dimensional spaced structure of polyester fiber and nylon is 30-40%. The 75D / 36F low-elasticity polyester fiber has fine filaments with a certain degree of elasticity. The weft-knitted three-dimensional spaced structure formed by weaving is bulky. The 30-40% bulkiness can store more air, improve the energy absorption effect of the buffer layer, and enhance the absorption and dispersion of external impact forces. At the same time, the characteristics of low-elasticity yarn make the buffer layer less prone to deformation after being subjected to force. It can still maintain good buffering performance after long-term use and avoid the weakening of the protective effect due to the decrease in bulkiness.

[0033] As one embodiment of this utility model, the blending ratio of combed cotton to Modal fiber is further 6:4. This 6:4 blending ratio of combed cotton to Modal fiber can give full play to the advantages of the two fibers. Combed cotton can ensure the softness, breathability and moisture-wicking properties of the skin-friendly base layer 101, reducing the feeling of stuffiness on the skin. Modal fiber, on the other hand, improves the smoothness, luster and wrinkle resistance of the fabric, preventing the fabric from pilling or deforming after wearing it for a long time. It balances skin-friendly comfort and fabric durability, making it suitable for use in close-fitting protective scenarios.

[0034] As one embodiment of this utility model, it further includes a reinforcing mesh layer, which is disposed between the buffer intermediate layer 102 and the skin-friendly base layer 101. The reinforcing mesh layer is made of polyester mesh fabric. The polyester mesh fabric reinforcing mesh layer disposed between the buffer intermediate layer 102 and the skin-friendly base layer 101 has a mesh structure that can enhance the bonding force between the two layers, prevent the fabric layers from separating, and improve the overall structural stability of the protective fabric body 1. The polyester material has high strength and wear resistance, which can further improve the tear resistance of the fabric. At the same time, the breathable structure of the mesh fabric will not affect the moisture absorption and breathability of the skin-friendly base layer 101, avoiding the fabric from becoming stuffy due to the addition of the reinforcing mesh layer, thus balancing structural strength and wearing comfort.

[0035] Specifically, the working principle of this weft-knitted protective fabric, which combines skin-friendly comfort and abrasion resistance, is as follows: During use, the protective fabric body 1 achieves all-around protection and comfort through the synergistic effect of its skin-friendly base layer 101, cushioning intermediate layer 102, abrasion-resistant surface layer 103, and reinforcing mesh layer. First, the skin-friendly base layer 101, as the inner layer, uses a plain knit weave of a 6:4 blend of combed cotton and Modal fiber. The combed cotton provides softness, breathability, and moisture-wicking properties, quickly absorbing and releasing sweat from the skin surface to reduce stuffiness. The Modal fiber enhances the fabric's smoothness and wrinkle resistance, preventing pilling and deformation over long-term wear, ensuring a comfortable fit. The middle reinforcing mesh layer is made of polyester mesh fabric. Its mesh structure enhances the interlayer bonding between the skin-friendly base layer 101 and the cushioning intermediate layer 102, preventing fabric delamination. Furthermore, the high strength of polyester material improves the overall tear resistance of the fabric, while the mesh structure does not impede breathability, ensuring air circulation between layers. The cushioning intermediate layer 102 uses 75D / The weft-knitted three-dimensional interleaved structure, composed of 36F low-elasticity polyester fiber and nylon high-elasticity DTY, with a thickness of 0.5–1.2 mm and a bulk of 30–40%, allows for sufficient air storage within the layers. When subjected to external impact or compression, the air layer absorbs and disperses the impact force through deformation. Simultaneously, the high elastic recovery rate of nylon ensures that the cushioning layer rebounds quickly after being subjected to force, is not easily deformed, and continuously provides cushioning protection. The outermost abrasion-resistant surface layer 103 is composed of 30–40 wt% modified short-cut UHMWPE and 60… Composed of a double rib structure blended with ~70wt% aramid fiber, the thickness of 0.8~1.5mm ensures sufficient abrasion resistance while avoiding fabric stiffness. The high strength of UHMWPE enhances the surface impact resistance, while the high abrasion resistance of aramid fiber resists external friction. The double rib structure further improves the surface structure stability and prevents fiber shedding. It is suitable for outdoor work, sports protection and other scenarios. The overall design achieves an integrated protective effect of "skin-friendly comfort, cushioning and energy absorption, and abrasion resistance" through the complementary functions of each layer.

The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
