Description

Technical Field

[0001] This utility model relates to the field of textile fabrics, and in particular to a green and environmentally friendly fabric. Background Technology

[0002] Currently, in the textile fabric industry, with the increasing awareness of environmental protection and the continuous improvement of consumers' requirements for fabric performance, developing fabrics that combine environmental protection and high performance has become an important trend in industry development. For example, Chinese Patent Publication No. CN217705045U discloses an environmentally friendly fabric comprising a first environmentally friendly fabric layer, a second environmentally friendly fabric layer interwoven and connected to the top of the first environmentally friendly fabric layer, and a third environmentally friendly fabric layer interwoven and connected to the top of the second environmentally friendly fabric layer. The first environmentally friendly fabric layer is made of RPET fabric. This utility model's environmentally friendly fabric is composed of three interwoven parts: a first environmentally friendly fabric layer, a second environmentally friendly fabric layer, and a third environmentally friendly fabric layer. Therefore, while ensuring the fabric's environmental friendliness, its thickness is also increased, making it less prone to tearing. The second environmentally friendly fabric layer is woven from warp and weft threads, both of which are made from a blend of bamboo fiber and Tencel, with bamboo as the raw material.

[0003] Developing fabrics using renewable resources as raw materials and with green and environmentally friendly production processes has become an inevitable choice. For example, regenerated cellulose fiber, as an important environmentally friendly fiber material, has advantages such as biodegradability and renewability. However, how to effectively apply it to fabric structures to improve the overall environmental performance of the fabric still requires further research. In addition, it is difficult for a single fiber material to simultaneously meet these performance requirements. How to make fabrics possess multiple excellent properties through reasonable fiber combinations and structural design has become a key issue in fabric research and development. Utility Model Content

[0004] Therefore, in response to the above problems, this utility model proposes a green and environmentally friendly fabric, which aims to solve the technical problems of the shortcomings of traditional fabrics in terms of environmental protection and functionality through innovative material selection, fiber combination and structural design.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a green and environmentally friendly fabric, comprising a reinforcing surface layer and an environmentally friendly substrate layer, wherein a hot-melt yarn is provided between the reinforcing surface layer and the environmentally friendly substrate layer, the environmentally friendly substrate layer is made of regenerated cellulose fiber, the top and bottom ends of the hot-melt yarn are fixedly connected to the reinforcing surface layer and the environmentally friendly substrate layer respectively, and the hot-melt yarn is woven from hot-melt fibers;

[0006] The reinforcing surface layer is woven from fiber bundles, which include tensile fibers, flame-retardant fibers, absorbent fibers, polyester fibers, and corrosion-resistant fibers. The tensile fibers, flame-retardant fibers, absorbent fibers, polyester fibers, and corrosion-resistant fibers are bundled together to form a tight structure.

[0007] Furthermore, the absorbent fiber serves as the core wire, and the tensile fiber, flame-retardant fiber, polyester fiber, and corrosion-resistant fiber are tightly wound around the core wire in a spiral shape.

[0008] The fiber bundles are woven at a density of 50-80 strands per square centimeter in the reinforcing layer.

[0009] Furthermore, the mass ratio of the tensile fiber, flame-retardant fiber, absorbent fiber, polyester fiber and corrosion-resistant fiber is (3-4):(2-2.5):(2-2.5):(1-1.5):(0.5-1).

[0010] Furthermore, the tensile fiber is a high-strength polyethylene fiber with a single filament strength of not less than 30 cN / dtex and an elongation at break of 3%-5%.

[0011] The flame-retardant fiber is a modified acrylonitrile fiber with a limiting oxygen index of not less than 32%, which can self-extinguish in a flame and does not produce molten droplets;

[0012] The absorbent fiber is sodium polyacrylate modified viscose fiber;

[0013] The polyester fiber is a high-shrinkage polyester fiber with a shrinkage rate between 8% and 12%.

[0014] The corrosion-resistant fiber is polytetrafluoroethylene fiber.

[0015] Furthermore, the regenerated cellulose fiber is Tencel fiber, with a fineness of 1.0-1.5 denier and a length of 38-51 mm.

[0016] Furthermore, an inner liner is fixedly provided at the bottom of the environmentally friendly substrate layer, and the inner liner is bonded and fixed to the environmentally friendly substrate layer by an environmentally friendly adhesive.

[0017] Furthermore, the inner lining includes an activated carbon fiber cloth fixedly disposed at the bottom end of the environmentally friendly substrate layer, and an antibacterial fiber cloth is fixedly disposed at the bottom end of the activated carbon fiber cloth.

[0018] The activated carbon fiber cloth is woven from activated carbon fibers, which have a pore size of 2-5 nanometers and a specific surface area of ​​not less than 1000 m². 2 / g;

[0019] The antibacterial fiber cloth is woven from antibacterial fibers, which are silver-loaded antibacterial polyester fibers with a silver ion content of 0.5%-1.5%.

[0020] Furthermore, the activated carbon fiber cloth has a thickness of 0.2-0.5 mm and a weight of 80-120 g / m².

[0021] The antibacterial fiber cloth has a thickness of 0.1-0.3 mm, a weight of 50-80 g / m², and a weaving density of 100-150 threads per square centimeter.

[0022] Furthermore, the hot melt yarn is woven from hot melt fibers, which are copolyester hot melt fibers with a melting point of 110-130℃.

[0023] The thickness of the hot melt yarn is 0.05-0.1 mm, and the weight is 30-50 g / m².

[0024] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0025] 1. This solution achieves multifaceted performance improvements by establishing a green and environmentally friendly fabric structure consisting of a reinforcing surface layer, an environmentally friendly base layer, and a heat-fused yarn layer between them. The environmentally friendly base layer is made of regenerated cellulose fibers, making full use of renewable resources and reducing dependence on non-renewable resources, which aligns with environmental protection principles and reduces the environmental burden during fabric production. The heat-fused yarn layer enhances the connection between the reinforcing surface layer and the environmentally friendly base layer, making the overall fabric structure more stable, less prone to delamination, and extending the fabric's lifespan. Furthermore, the heat-fused fibers can melt under specific conditions, facilitating fabric processing and shaping. Simultaneously, the heat-fused yarn layer, as an intermediate layer, also provides cushioning and support, improving the fabric's feel and comfort. The reinforcing surface layer is woven from multiple fiber bundles; this composite fiber structure endows the fabric with various basic properties.

[0026] 2. The spiral-shaped, encircling structure allows various fibers to intertwine and tightly bind together, further enhancing the overall strength and stability of the fiber bundle and improving the fabric's tensile strength and abrasion resistance. Simultaneously, the absorbent fibers, located at the core, can more efficiently absorb water. When the fabric comes into contact with moisture, the absorbent fibers quickly absorb and store the water, while the other encircling fibers provide protection and support, preventing the absorbent fibers from excessively swelling and deforming due to water absorption, thus ensuring the fabric's structural stability when wet. The fiber bundles maintain a weave density of 50-80 strands per square centimeter in the reinforcing layer, ensuring both fabric density and breathability / softness without compromising breathability due to excessive density. This allows the fabric to maintain a comfortable wearing experience while providing excellent protective properties.

[0027] 3. Precisely proportioned fiber quality fully utilizes its characteristics and synergistically optimizes performance. A high proportion of tensile fibers enhances the fabric's tensile strength, making it suitable for high-intensity applications; a reasonable proportion of flame-retardant fibers imparts flame retardancy to the fabric, improving safety; a balanced ratio of absorbent fibers and polyester fibers balances water absorption and dimensional stability; and corrosion-resistant fibers enhance the fabric's resistance to chemical corrosion, extending its service life in harsh environments.

[0028] 4. High-strength polyethylene fiber makes the fabric lightweight and has high tensile strength, capable of withstanding significant tensile forces and offering good impact resistance. Modified acrylonitrile fiber has a high limiting oxygen index, is self-extinguishing, and produces no molten droplets, effectively preventing the spread of fire and reducing the risk of combustion. Sodium polyacrylate modified viscose fiber has strong water absorption, quickly absorbing water to keep the fabric relatively dry and improving moisture-wicking performance. High-shrinkage polyester fiber causes the fabric to shrink and wrinkle after processing, increasing its three-dimensionality and texture, while maintaining dimensional stability, wrinkle resistance, and flatness, extending the time it retains its appearance. Polytetrafluoroethylene fiber has excellent chemical stability, resisting the corrosive effects of various chemicals, allowing the fabric to be used for a long time in harsh environments such as chemical and medical settings, extending its service life.

[0029] 5. Activated carbon fiber cloth: Its rich microporous structure and high specific surface area give it a powerful adsorption capacity, effectively adsorbing harmful gases and odors, purifying the air and improving odor. Antibacterial fiber cloth: Silver-impregnated antibacterial polyester fibers give the fabric antibacterial properties. Silver ions destroy bacterial structures, inhibiting growth and reproduction, reducing bacterial proliferation, lowering the risk of infection and odor, and ensuring health.

[0035] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0036] refer to Figure 1 , Figure 2 This embodiment provides a green and environmentally friendly fabric, including a reinforcing surface layer 1 and an environmentally friendly substrate layer 2. A hot-melt yarn 3 is provided between the reinforcing surface layer 1 and the environmentally friendly substrate layer 2. The environmentally friendly substrate layer 2 is made of regenerated cellulose fiber. The top and bottom ends of the hot-melt yarn 3 are fixedly connected to the reinforcing surface layer 1 and the environmentally friendly substrate layer 2, respectively. The hot-melt yarn 3 is woven from hot-melt fibers.

[0037] The reinforcing surface layer 1 is woven from fiber bundles, which include tensile fibers 4, flame-retardant fibers 5, water-absorbing fibers 6, polyester fibers 7, and corrosion-resistant fibers 8.

[0038] The fiber components in the fiber bundle are tightly combined through a special weaving structure to achieve comprehensive performance improvement in the fabric in terms of elasticity, strength, flame retardancy, water absorption and corrosion resistance.

[0039] The absorbent fiber 6 serves as the core wire, and the tensile fiber 4, flame-retardant fiber 5, polyester fiber 7, and corrosion-resistant fiber 8 are tightly wound around the core wire in a spiral shape.

[0040] Furthermore, during the weaving process, the spacing between the fibers in the spirally wrapped fiber bundle is controlled at 0.1-0.3 mm to ensure the overall structural stability of the fiber bundle and the synergistic performance of each fiber. At the same time, the weaving density of the fiber bundle in the reinforcing layer 1 is 50-80 fibers per square centimeter, so that the reinforcing layer 1 has both good elastic recovery performance and sufficient structural strength.

[0041] The mass ratio of the tensile fiber 4, flame retardant fiber 5, water-absorbing fiber 6, polyester fiber 7 and corrosion-resistant fiber 8 is (3-4):(2-2.5):(2-2.5):(1-1.5):(0.5-1), for example, a mass ratio of 4:2:2:1:1;

[0042] The tensile fiber 4 is a high-strength polyethylene fiber with a single filament strength of not less than 30 cN / dtex and a breaking elongation of 3%-5%, so as to provide the fabric with excellent tensile properties.

[0043] The flame-retardant fiber 5 is a modified acrylonitrile fiber with a limiting oxygen index of not less than 32%. It can self-extinguish in a flame and does not produce molten droplets, effectively improving the flame-retardant safety of the fabric.

[0044] The absorbent fiber 6 is a sodium polyacrylate modified viscose fiber, which has a water absorption rate of 20-30 times its own weight, and can quickly absorb and lock in moisture to keep the fabric dry.

[0045] The polyester fiber 7 is a high-shrinkage polyester fiber 7 with a shrinkage rate between 8% and 12%. When combined with other fibers, it gives the fabric better dimensional stability and wrinkle resistance during processing and use.

[0046] The corrosion-resistant fiber 8 is polytetrafluoroethylene fiber, which has good chemical stability and can resist the erosion of various acids, alkalis and organic solvents, thus extending the service life of the fabric.

[0047] The regenerated cellulose fiber is Tencel fiber, and the fineness of the Tencel fiber is 1.0-1.5 denier, and the length is 38-51 mm;

[0048] The Tencel fiber undergoes a special environmentally friendly treatment process, which does not use any harmful chemicals in the production process and is biodegradable, making it environmentally friendly.

[0049] Meanwhile, the Tencel fiber has good moisture absorption and breathability, with a moisture regain rate of 12%-15%, which makes the wearer feel comfortable.

[0050] The content of Tencel fiber in the environmentally friendly substrate layer 2 is not less than 80% to ensure the overall environmental performance and comfort of the fabric.

[0051] The hot melt yarn 3 is woven from hot melt fibers, which are copolyester hot melt fibers with a melting point of 110-130℃. During the hot pressing process, it can achieve a firm bond with the reinforcing surface layer 1 and the environmentally friendly substrate layer 2 at a lower temperature, thus avoiding heat damage to the main fibers of the fabric.

[0052] The thickness of the hot melt yarn 3 is 0.05-0.1 mm, and the weight is 30-50 g / m². Its weave structure is plain weave, which makes the hot melt yarn 3 evenly distributed in the fabric, effectively enhancing the bonding strength between the reinforcing surface layer 1 and the environmentally friendly substrate layer 2, and improving the overall stability and durability of the fabric.

[0053] See again Figure 3 This second embodiment provides a green and environmentally friendly fabric based on the same inventive concept, which differs from the first embodiment in that:

[0054] An inner liner is fixedly provided at the bottom end of the environmentally friendly substrate layer 2, and the inner liner is bonded and fixed to the environmentally friendly substrate layer 2 by an environmentally friendly adhesive.

[0055] The environmentally friendly adhesive is a water-based polyurethane adhesive with a solid content of 30%-40%, a bonding strength of not less than 15N / 25mm, and does not release harmful volatile organic compounds (VOCs) during production and use, thus meeting environmental protection requirements.

[0056] The inner lining includes an activated carbon fiber cloth 9 fixedly disposed at the bottom end of the environmentally friendly substrate layer 2, and an antibacterial fiber cloth 10 is fixedly disposed at the bottom end of the activated carbon fiber cloth 9.

[0057] The activated carbon fiber cloth 9 is woven from activated carbon fibers, the pore size of which is 2-5 nanometers and the specific surface area is not less than 1000 m². 2 / g, can effectively adsorb odors, harmful gases and fine particulate matter in the air, with an adsorption rate of over 90%;

[0058] The antibacterial fiber fabric 10 is woven from antibacterial fibers, which are silver-loaded antibacterial polyester fibers with a silver ion content of 0.5%-1.5%. The antibacterial rate against common bacteria such as Escherichia coli and Staphylococcus aureus is not less than 99%, and the antibacterial rate can still be maintained above 90% after 50 washes, providing the fabric with a long-lasting antibacterial protective function.

[0059] The activated carbon fiber cloth 9 has a thickness of 0.2-0.5 mm and a weight of 80-120 g / m². Its surface is treated with a special hydrophobic treatment, which makes the fabric less susceptible to moisture absorption while adsorbing harmful substances, keeping it dry.

[0060] The antibacterial fiber cloth 10 has a thickness of 0.1-0.3 mm, a weight of 50-80 g / m², and a weaving density of 100-150 threads per square centimeter. While ensuring antibacterial performance, it also has good breathability, ensuring that the wearer's skin can breathe smoothly.

[0061] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
