Description

Technical Field

[0001] This utility model belongs to the technical field of fabrics that prevent molten metal splashing, and in particular relates to a washable, heat-insulating fabric that prevents molten metal splashing. Background Technology

[0002] In metal smelting, casting, and other workplaces, there is a hazard of molten metal splashing. To avoid or reduce injury to workers from molten metal, it is necessary to equip operators with appropriate levels of protective clothing against molten metal splashes. Both GB 8965.1 "Protective Clothing - Molten Metal Splash Protective Clothing" and ISO 11612 "Protective Clothing Against Heat and Flame" specify three levels of protection against molten metal splashes.

[0003] Currently, the protective clothing used on a large scale in the market for protection against molten metal splashes is mainly made of wool / flame-retardant viscose blends and flame-retardant cotton. Wool / flame-retardant viscose blends offer the best actual protective effect and are used most extensively. However, this fabric presents several challenges in production and application: 1. To accommodate different protection levels, the fabric needs to be thicker and heavier; 2. Due to the felting and shrinkage characteristics of wool fibers, there is a significant shrinkage rate after each wash; 3. Wool has relatively low flame retardancy, making it difficult to control the fabric's flame retardancy; 4. Wool fabric has a rough feel and is uncomfortable to wear.

[0004] Therefore, it is necessary to improve the aforementioned production and application issues as much as possible. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a washable, heat-insulating and molten metal splash-proof fabric, which has excellent molten metal splash protection performance, and is flame-retardant and skin-friendly.

[0006] To achieve the above objectives, this utility model provides a washable, heat-insulating, and molten metal-splash-resistant fabric, comprising a surface layer and an inner layer layer layered together; the surface layer layer is woven from wool yarn, flame-retardant viscose yarn, and / or nylon blended yarn; the inner layer layer is woven from flame-retardant acrylic yarn, Tencel yarn, and / or aramid blended yarn; the surface layer layer and the inner layer layer are joined together to form a whole by the surface warp yarn of the surface layer layer and the inner weft yarn of the inner layer layer.

[0007] In one embodiment, the yarn of the outer layer is thicker than the yarn of the inner layer.

[0008] In one embodiment, the yarn count of the surface layer is: Ne: 23 / 2s-36 / 2s.

[0009] In one embodiment, the yarn count of the inner layer is: Ne: 45 / 2s-55 / 2s.

[0010] In one implementation, the density of the outer layer is higher than that of the inner layer.

[0011] In one embodiment, the density of the surface tissue is 70%-90%.

[0012] In one embodiment, the density of the inner layer is 60%-80%.

[0013] In one implementation, the surface texture is a twill, plain, or satin weave.

[0014] In one embodiment, the inner layer is constructed using a plain weave.

[0015] The beneficial technical effects of this utility model due to the adoption of the above technical solution include:

[0016] The outer layer is woven from wool yarn, flame-retardant viscose yarn, or nylon blended yarn; the inner layer is woven from flame-retardant acrylic yarn, Tencel yarn, or aramid blended yarn. This allows the fabric to integrate the excellent molten metal splash protection of the outer layer with the excellent flame-retardant, washable, high carbonization temperature, and skin-friendly properties of the inner layer. The outer and inner layers are connected as a whole by the outer warp yarns of the outer layer and the inner weft yarns of the inner layer, enhancing the structural stability of the fabric and preventing relative displacement between the outer and inner layers. This results in a smoother, more even fabric surface while maintaining internal softness. This structure ensures both the appearance quality of the fabric and enhances comfort during wear and use. Furthermore, because this structure is thicker than a single-layer structure, it provides better thermal insulation and effectively reduces the weight of high-grade protective fabrics. The yarns of the outer fabric are thicker than those of the inner fabric. The thicker yarns provide a thicker protective layer, increasing the fabric's thermal resistance and effectively blocking heat transfer, thus better protecting firefighters from high temperatures and flames, while the inner layer maintains good comfort.

[0026] Example 1

[0027] Please see Figure 1 and Figure 2The present invention discloses a washable, heat-insulating, and molten metal-splash-resistant fabric according to Embodiment 1, comprising a surface layer 1 and an inner layer 2 layered together; the surface layer 1 is woven from wool yarn, flame-retardant viscose yarn, and / or nylon blended yarn; the inner layer 2 is woven from flame-retardant acrylic yarn, Tencel yarn, and / or aramid blended yarn; the surface layer 1 and the inner layer 2 are connected to form a whole by the surface warp yarn of the surface layer 1 and the inner weft yarn of the inner layer 2.

[0028] In this embodiment, the outer layer 1 is woven from wool yarn, flame-retardant viscose yarn, and nylon blended yarn; the inner layer 2 is woven from flame-retardant acrylic yarn, Tencel yarn, and aramid blended yarn.

[0029] Wool yarn has a unique scaly structure that allows molten metal to slide off smoothly when splashed onto the fabric, preventing metal droplets from adhering to the fabric surface and thus reducing the risk of burns to the wearer. Wool also possesses a certain degree of thermal stability at high temperatures, providing some insulation. Furthermore, wool enhances the overall durability and impact resistance of fabrics.

[0030] Flame-retardant viscose fiber is an inherently flame-retardant fiber that does not melt and drip when exposed to fire, but instead carbonizes, preventing secondary injuries. Flame-retardant viscose fiber also has excellent heat insulation properties, effectively blocking heat transfer and protecting the wearer from high-temperature injuries. Furthermore, flame-retardant viscose fiber is low-smoke, non-toxic, and biodegradable, making it an environmentally friendly flame-retardant fiber.

[0031] Nylon fibers possess excellent abrasion resistance, enhancing fabric durability and making it less prone to damage in complex working environments. The addition of nylon fibers significantly improves the fabric's breaking strength and tear strength, enhancing its overall structural stability. When blended with flame-retardant viscose and wool, nylon fibers effectively prevent the adhesion and penetration of molten metal droplets, providing excellent protection.

[0032] Flame-retardant acrylonitrile fiber is an inherently flame-retardant fiber. The fiber itself is flame-retardant and will not burn when exposed to fire; it will only char and will not drip.

[0033] Tencel possesses excellent softness and moisture absorption, resulting in a soft and comfortable feel when blended. This helps improve the comfort of firefighters wearing protective clothing for extended periods, reducing fatigue. The good moisture absorption and breathability of Tencel fibers allow blended fabrics to better regulate the wearer's body humidity and temperature. In the high-temperature environment of a fire scene, excellent breathability and moisture absorption help firefighters keep their bodies dry, improving work efficiency.

[0034] Aramid is a high-temperature resistant fiber, and its addition to blends significantly improves the thermal stability of fabrics. In high-temperature environments, blended fabrics are less prone to shrinkage, deformation, or damage, providing better protection for firefighters from heat-related injuries. Aramid fibers have excellent heat shrinkage resistance, and blending them effectively reduces dimensional changes in the fabric at high temperatures. This allows fire protective clothing to maintain good fit and protective performance even in high-temperature environments.

[0035] When acrylic chlorofiber is blended with Tencel or aramid, its limiting oxygen index (LOI) can reach a high level. For example, when acrylic chlorofiber is blended with cotton, the limiting oxygen index can reach 28 to 32. Flame-retardant acrylic chlorofiber exhibits smoldering during combustion, but by blending it with fibers such as Tencel and aramid, its smoldering time can be effectively reduced.

[0036] The yarns of the outer layer 1 are thicker than the yarns of the inner layer 2.

[0037] Coarser yarns provide a thicker protective layer, increasing the fabric's thermal resistance and effectively blocking heat transfer, thus better protecting firefighters from high temperatures and flames, while the inner layer maintains good comfort.

[0038] The yarn count of the surface layer 1 is: Ne: 23 / 2s-36 / 2s.

[0039] The yarn count of the inner layer 2 is: Ne: 45 / 2s-55 / 2s.

[0040] In this embodiment, the yarn count of the outer layer 1 is Ne: 28 / 2s. The yarn count of the inner layer 2 is Ne: 50 / 2s.

[0041] The density of the outer layer 1 is higher than that of the inner layer 2.

[0042] The outer layer 1 has a high density and a more compact yarn arrangement, effectively resisting external friction and impact, and extending the fabric's lifespan. The dense outer layer 1 can effectively block the penetration of harmful substances such as molten metal, sparks, and chemicals, providing better protection. In addition, the high density of the outer layer 1 provides higher strength and stability, reducing wear and deformation during use. Meanwhile, the inner layer 2 has a lower density, maintaining a soft and comfortable feel, enhancing the wearing experience.

[0043] The density of the surface tissue 1 is 70%-90%.

[0044] The density of the inner layer 2 is 60%-80%.

[0045] In this embodiment, the density of the surface tissue 1 is 80%, and the density of the inner tissue 2 is 70%.

[0046] The surface weave 1 is a twill, plain, or satin weave. In this embodiment, the surface weave 1 is a twill weave.

[0047] The inner layer 2 has a plain weave.

[0048] The outer layer 1 is woven from wool yarn, flame-retardant viscose yarn, or nylon blended yarn; the inner layer 2 is woven from flame-retardant acrylic yarn, Tencel yarn, or aramid blended yarn. This allows the fabric to integrate the excellent molten metal splash protection of the outer layer 1 with the excellent flame-retardant, washable, high carbonization temperature, and skin-friendly properties of the inner layer 2. The outer layer 1 and the inner layer 2 are connected as a whole by the outer warp yarns of the outer layer 1 and the inner weft yarns of the inner layer 2, enhancing the structural stability of the fabric and preventing relative displacement between the outer and inner layers. This makes the fabric surface smoother and flatter while maintaining its softness. This structure ensures both the appearance quality of the fabric and the comfort during wear or use. Furthermore, because this structure is thicker than a single-layer structure, it provides better thermal insulation and can effectively reduce the weight of high-grade protective fabrics.

The difference is that the surface layer 1 is made of wool yarn and flame-retardant viscose yarn; the inner layer 2 is made of flame-retardant acrylonitrile yarn and aramid blended yarn.

[0051] The yarn count of the outer layer 1 is Ne: 30 / 2s. The yarn count of the inner layer 2 is Ne: 47 / 2s.

[0052] The density of the outer layer 1 is 85%. The density of the inner layer 2 is 75%.

[0055] The yarn count of the outer layer 1 is Ne: 25 / 2s. The yarn count of the inner layer 2 is Ne: 53 / 2s.
