Description

Technical Field

[0001] The present invention relates to the technical field of textile fabrics, and particularly relates to a waterproof textile fabric for underwater operations. Background Art

[0002] With the development of fields such as underwater exploration, ocean engineering, and emergency rescue, underwater operations have become the core activities for humans to explore and utilize the underwater environment. During underwater operations, in order to ensure the safety, efficiency, and comfort of the operations, waterproof textile fabrics are usually selected as key basic materials. Existing waterproof textile fabrics usually consist of an electrostatic layer, an elastic fiber layer, a breathable layer, a waterproof layer, a wear-resistant layer, a strengthening layer, and an antibacterial layer.

[0003] For example: The utility model with the application number CN202023322116.7 discloses a waterproof textile dyeing fabric, which specifically includes a fabric body. Patterns are laid on the surface of the fabric body. The fabric body includes an antistatic layer, an elastic fiber layer, a breathable layer, a waterproof layer, a wear-resistant layer, a strengthening layer, and an antibacterial layer. An antistatic layer is arranged at the top of the fabric body. The bottom end of the antistatic layer is fixedly connected with an elastic fiber layer. The bottom end of the elastic fiber layer is fixedly connected with a breathable layer. The bottom end of the breathable layer is fixedly connected with a waterproof layer. The bottom end of the waterproof layer is fixedly connected with a wear-resistant layer. The bottom end of the wear-resistant layer is fixedly connected with a strengthening layer. The bottom end of the strengthening layer is fixedly connected with an antibacterial layer. Conductive fiber filaments are evenly arranged inside the antistatic layer, and the conductive fiber filaments cooperate with each other to form an antistatic structure. The elastic fiber layer is made of polyurethane fiber. The composition is 45% cotton, 47% regenerated fiber, and 8% Lycra. A large amount of cotton pulp fiber filaments are added to the pure cotton fabric. This kind of fabric has a simple and reasonable structure and has good waterproof effects.

[0004] However, during underwater operations, underwater particulate pollutants, such as sediment and minerals, are likely to adhere due to changes in water flow velocity or the rough structure of the fabric surface. At the same time, microorganisms, algae, barnacles, etc. in the water will also form biofilms on the fabric surface. These attachments and biofilms are likely to block the micropores of the fabric, making it easier for water to penetrate into the fabric interior, reducing its waterproof effect, and at the same time reducing the wear resistance of the fabric and accelerating the aging of the fabric, which is inconvenient to use. Summary of the Invention

[0005] In view of this, the present invention provides a waterproof textile fabric for underwater operations, which has an anti-fouling layer capable of preventing the attachment of attachments and the formation of biofilms. The oleophobic fibers of the anti-fouling layer have an extremely low surface energy and can form a hydrophobic and oleophobic interface similar to the lotus leaf effect, making it difficult for liquid or solid pollutants such as seawater, grease, and sediment to adhere. The antibacterial fibers inhibit the reproduction of bacteria and fungi by destroying the cell membranes or metabolic enzymes of microorganisms, avoiding the formation of biofilms, and enabling the fabric to resist underwater pollution.

[0006] The present invention provides the purpose and efficacy of a waterproof textile fabric for underwater operations, specifically including: a skin-friendly comfort layer, on the upper surface of which a deodorant layer is woven; on the upper surface of the deodorant layer, an energy-absorbing layer is woven; on the upper surface of the energy-absorbing layer, an adhesive layer is provided; on the upper surface of the adhesive layer, a waterproof and breathable layer is provided; on the upper surface of the waterproof and breathable layer, an elastic buffer layer is woven; on the upper surface of the elastic buffer layer, a high-strength wear-resistant layer is woven; on the upper surface of the high-strength wear-resistant layer, a stain-resistant layer is woven.

[0007] Furthermore, the skin-friendly comfort layer is woven in a plain weave with cotton fibers and spandex fibers; the total thickness of the skin-friendly comfort layer is between 0.1 - 0.2 mm; the ratio between cotton fibers and spandex fibers is 7:3.

[0008] Furthermore, the deodorant layer is double-sided weft-knitted with regenerated cellulose fibers containing silver ion antibacterial agents; the total thickness of the deodorant layer is between 0.1 - 0.2 mm.

[0009] Furthermore, the energy-absorbing layer is filled with polyester fiber three-dimensional crimped hollow cotton; the total thickness of the energy-absorbing layer is between 0.3 - 0.5 mm.

[0010] Furthermore, the adhesive layer is composed of a hot melt adhesive web; the total thickness of the adhesive layer is between 0.02 - 0.05 mm.

[0011] Furthermore, the waterproof and breathable layer is composed of a polytetrafluoroethylene microporous membrane; the micropore diameter of the waterproof and breathable layer is between 0.2 - 0.5 μm; the total thickness of the waterproof and breathable layer is between 0.05 - 0.1 mm.

[0012] Furthermore, the elastic buffer layer is blended with spandex fibers and polyamide fibers; the ratio between the spandex fibers and polyamide fibers in the blend is 7:3; the total thickness of the elastic buffer layer is between 0.1 - 0.2 mm.

[0013] Furthermore, the high-strength wear-resistant layer is warp-knitted with aramid fibers coated with microcapsules; the total thickness of the high-strength wear-resistant layer is between 0.2 - 0.3 mm.

[0014] Furthermore, the stain-resistant layer is composed of a composite weave of oil-repellent fibers and antibacterial fibers; the ratio between the oil-repellent fibers and antibacterial fibers is 4:1; the total thickness of the stain-resistant layer is between 0.1 - 0.15 mm.

[0015] Beneficial effects The silver ions in the deodorant layer of the present invention can effectively inhibit the growth and reproduction of microorganisms such as bacteria and fungi, achieving the effect of antibacterial and deodorizing, reducing the generation of odors, and at the same time, it can also reduce the skin infections of operators, effectively improving the safety of the waterproof textile fabric.

[0016] The three-dimensional crimped hollow polyester fiber of the energy-absorbing layer has a three-dimensional crimped structure. When working underwater, it can absorb and disperse the pressure of the water flow, reduce the vibration and impact on the operator, and play a role in shock absorption. At the same time, the three-dimensional crimped hollow polyester fiber also has good heat preservation performance and fluffiness, effectively improving the comfort and safety of the waterproof textile fabric.

[0017] The aramid fiber of the high-strength wear-resistant layer has extremely high strength and modulus, enhancing the overall strength and wear resistance of the fabric. The warp knitting method can form a unidirectional high tensile strength, enabling the fabric to better resist unidirectional stresses such as longitudinal scratching and dragging during underwater operations. At the same time, the microcapsules in the aramid fiber can rupture when the high-strength wear-resistant layer is worn, releasing the curing agent in the microcapsules to repair the worn parts of the high-strength wear-resistant layer, effectively improving the service life of the waterproof textile fabric and enhancing its practicality.

[0018] The oleophobic fiber of the anti-fouling layer has an extremely low surface energy, which can form a hydrophobic and oleophobic interface similar to the lotus leaf effect, making it difficult for liquid stains such as water, oil, and mud to penetrate or adhere. This avoids the fabric becoming heavier due to stain accumulation and increasing resistance during underwater operations. At the same time, the oleophobic fiber can reduce particle retention through its extremely low surface, reduce the sandpaper effect, and extend the service life of the fabric. The antibacterial fiber inhibits the reproduction of bacteria and fungi by destroying the cell membrane or metabolic enzymes of microorganisms, blocking the formation of biofilms from the source, enabling the fabric to resist underwater pollution, ensuring that the fabric maintains a waterproof and breathable structure, and effectively improving the applicability of the waterproof textile fabric.

Please refer to Figures 1 to 5 as shown, including: skin-friendly comfort layer 1, deodorizing layer 2, energy-absorbing layer 3, adhesive layer 4, waterproof and breathable layer 5, elastic buffer layer 6, high-strength wear-resistant layer 7, anti-fouling layer 8 On the upper surface of the skin-friendly comfort layer 1, the deodorizing layer 2 is woven; on the upper surface of the deodorizing layer 2, the energy-absorbing layer 3 is woven; on the upper surface of the energy-absorbing layer 3, the adhesive layer 4 is provided; on the upper surface of the adhesive layer 4, the waterproof and breathable layer 5 is provided; on the upper surface of the waterproof and breathable layer 5, the elastic buffer layer 6 is woven; on the upper surface of the elastic buffer layer 6, the high-strength wear-resistant layer 7 is woven; on the upper surface of the high-strength wear-resistant layer 7, the anti-fouling layer 8 is woven.

[0028] Among them, the skin-friendly comfort layer 1 is woven in plain weave with cotton fiber and spandex fiber; the total thickness of the skin-friendly comfort layer 1 is between 0.1 - 0.2 mm; the ratio between the cotton fiber and the spandex fiber is 7:3.

[0030] Among them, the energy-absorbing layer 3 is filled with polyester fiber three-dimensional crimped hollow cotton; the total thickness of the energy-absorbing layer 3 is between 0.3 - 0.5 mm.

[0031] Among them, the adhesive layer 4 is composed of a hot melt adhesive web; the total thickness of the adhesive layer 4 is between 0.02 - 0.05 mm.

[0034] Among them, the high-strength wear-resistant layer 7 is warp-knitted with aramid fiber coated with microcapsules; the total thickness of the high-strength wear-resistant layer 7 is between 0.2 - 0.3 mm.

[0035] Specific usage and functions of this embodiment: In the present invention, the skin-friendly and comfortable layer 1 woven from cotton fiber and spandex fiber endows the fabric with moderate elasticity, enabling the fabric to fit the body and move freely, reducing the irritation to the skin, and providing a good wearing experience for the operators. The silver ions in the deodorant layer 2 can effectively inhibit the growth and reproduction of microorganisms such as bacteria and fungi, achieving the effect of antibacterial and deodorant, reducing the generation of odors. The polyester fiber three-dimensional crimped hollow cotton has a three-dimensional crimped structure, which can absorb and disperse the pressure of water flow during underwater operations, reduce the vibration and impact received by the operators, and play a role in shock absorption. At the same time, the polyester fiber three-dimensional crimped hollow cotton also has good heat preservation performance and fluffiness, providing heat preservation performance for the fabric.

The micropore diameter of the waterproof and breathable layer 5 is smaller than the diameter of water droplets but larger than the diameter of water vapor molecules. This micropore diameter endows the waterproof and breathable layer 5 with excellent waterproof and breathable properties, which can effectively prevent the intrusion of water during underwater operations. At the same time, since the micropore diameter is larger than water vapor molecules, it can ensure that water vapor such as the sweat of the operators can be discharged from the fabric, keeping the operators dry. The spandex fiber has high elasticity and can provide good stretchability, while the nylon fiber has certain strength and wear resistance. Therefore, the elastic buffer layer 6 spun from spandex fiber and nylon fiber has good elasticity and buffer performance, which can play a buffer role when subjected to external force impact, adding a layer of buffer protection to the fabric while increasing its flexibility. The aramid fiber has extremely high strength and modulus, enhancing the overall strength and wear resistance of the fabric. The warp knitting method can form a unidirectional high tensile strength, enabling the fabric to better resist unidirectional stresses such as longitudinal scratching and dragging during underwater operations. At the same time, the microcapsules in the aramid fiber can rupture when the high-strength wear-resistant layer is worn, releasing the curing agent in the microcapsules to repair the worn parts of the high-strength wear-resistant layer. The core material of the microcapsules is epoxy resin + latent curing agent, and the wall material is melamine-formaldehyde resin.

[0037] Specific usage and function of this embodiment: In the present invention, the oil-repellent fiber is a fluoropolymer. The oil-repellent fiber has an extremely low surface energy and can form a hydrophobic and oleophobic interface similar to the lotus leaf effect, making it difficult for liquid or solid pollutants such as seawater, grease, and sediment to adhere. The antibacterial fiber is a composite fiber of silver-loaded zeolite and chitosan. The antibacterial fiber inhibits the reproduction of bacteria and fungi and avoids the formation of biofilms by destroying the cell membranes or metabolic enzymes of microorganisms, enabling the fabric to resist underwater pollution.
