Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to a lightweight, breathable, environmentally friendly, soft viscose fabric. Background Technology

[0002] As people's demands for the functionality, comfort, and environmental performance of textiles continue to rise, traditional fabrics are finding it increasingly difficult to meet the needs of modern consumers in terms of moisture wicking, breathability, waterproofing, and antibacterial properties, especially in the sportswear and outdoor apparel sectors. While existing viscose fabrics possess good softness and moisture absorption, they still fall short in terms of moisture-wicking efficiency, dryness, and durability. For example, ordinary viscose fabrics tend to cling to the skin after absorbing moisture, leading to discomfort; simultaneously, the lack of effective moisture transport pathways makes it difficult for sweat to evaporate quickly, negatively impacting the wearing experience.

[0003] In addition, existing waterproof fabrics often use dense coatings or membranes to prevent water penetration, but these structures often affect the breathability of the fabric, causing a stuffy feeling. Utility Model Content

[0004] This utility model provides a lightweight, breathable, and environmentally friendly viscose soft fabric, including a fabric body. The fabric body includes a base fabric layer, which is made of a blend of warp and weft yarns. The surface of the base fabric layer has a microporous structure, which is formed by laser perforation. The pore size is 50-100 micrometers and the pore spacing is 200-300 micrometers. The back of the base fabric layer is laminated with a breathable and waterproof membrane, which is made of bio-based polyester material, has a thickness of 10-20 micrometers, and a breathability of not less than 500g / m² / 24h. The surface of the base fabric layer is provided with a hydrophilic functional layer.

[0005] Preferably, the warp yarn is made of natural plant fiber, and the weft yarn is made of viscose fiber. The viscose fiber and the natural plant fiber are interwoven in a cross-weave structure, wherein the natural plant fiber is distributed along the warp and the viscose fiber is distributed along the weft, forming a composite structure with directional moisture-wicking function.

[0006] Preferably, both the warp and weft yarns are hollow fibers with axially extending moisture-wicking cavities inside, which are interconnected with the surface microporous structure to form a three-dimensional moisture-wicking structure.

[0007] Preferably, the microporous structures are distributed in a regular array on the surface of the base fabric layer, and the edges of each microporous structure are rounded.

[0008] Preferably, an intermediate connecting layer is provided between the base fabric layer and the breathable waterproof membrane, and the intermediate connecting layer is a hot melt adhesive film with an open structure.

[0009] Preferably, an antibacterial layer is embedded inside the intermediate connecting layer.

[0010] Preferably, the antibacterial layer is a porous film containing silver ions, which is integrally formed with the intermediate connecting layer during the manufacturing process to form a composite structure that has both adhesive function and antibacterial properties.

[0011] Preferably, the breathable and waterproof membrane has a porous nonwoven structure with interconnected microchannels inside, which allows water vapor to pass through while preventing liquid water from penetrating.

[0012] Preferably, the hydrophilic functional layer is a porous mesh structure that covers the fiber surface of the base fabric layer and forms a continuous moisture-wicking path with the microporous structure.

[0013] Preferably, the hydrophilic functional layer is composed of one or more of polyvinyl alcohol, chitosan, or hydroxyethyl cellulose.

[0014] This utility model provides a lightweight, breathable, and environmentally friendly viscose soft-feel fabric, which, compared with the prior art:

[0015] 1. This invention features a microporous structure on the surface of a base fabric layer, combined with hollow fiber structures for both warp and weft yarns. Internally, axially extending moisture-wicking channels connect with the surface microporous structure, forming a three-dimensional moisture-wicking structure. This design not only increases the fabric's breathability and moisture-wicking efficiency but also allows moisture to be quickly transferred from the skin surface to the outer layer and expelled through the microporous structure, keeping the skin dry. Furthermore, a hydrophilic functional layer composed of hydrophilic materials such as polyvinyl alcohol, chitosan, or hydroxyethyl cellulose further enhances the fabric's moisture-wicking capacity and wearing comfort. Overall, this multi-layered moisture-wicking system effectively improves the fabric's moisture-wicking performance, ensuring a comfortable wearing experience even during exercise or in hot weather.

[0016] 2. This invention achieves high breathability and prevents liquid water penetration by laminating a 10-20 micrometer thick, breathable and waterproof membrane with a breathability of not less than 500 g / m² / 24h onto the back of the base fabric layer. The intermediate connecting layer is a hot-melt adhesive film with an open-pore structure, embedding an antibacterial layer containing silver ions, and is integrally formed with the intermediate connecting layer, enhancing the interlayer bonding strength and providing antibacterial protection. The porous nonwoven structure of the breathable and waterproof membrane ensures water vapor permeability while preventing liquid water penetration, improving the overall performance of the fabric and making it suitable for various outdoor activities and everyday wear.

[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please refer to Figures 1-7This utility model provides a lightweight, breathable, and environmentally friendly viscose soft fabric, including a fabric body 10. The fabric body 10 includes a base fabric layer 11, which is made of a blend of warp yarns 112 and weft yarns 113. The warp yarns 112 are made of natural plant fibers, preferably at least one of cotton, linen, or bamboo fibers. The weft yarns 113 are made of viscose fibers. The viscose fibers and natural plant fibers are interwoven to form a composite structure with directional moisture-wicking function. The natural plant fibers are distributed along the warp direction, and the viscose fibers are distributed along the weft direction, which is beneficial for achieving directional control of the moisture absorption and wicking path.

[0028] The surface of the base fabric layer 11 is provided with microporous structures 111, which are formed by laser drilling. The pore size is 50–100 micrometers and the pore spacing is 200–300 micrometers. The microporous structures 111 are regularly distributed in an array on the surface of the base fabric layer 11, and the edges of each microporous structure 111 are rounded to reduce stress concentration and improve the strength of the fabric.

[0029] Furthermore, both the warp yarn 112 and the weft yarn 113 are hollow fibers with axially extending moisture-wicking channels inside. These channels are interconnected with the surface microporous structure 111, forming a three-dimensional moisture-wicking structure that enables efficient moisture transfer from the inside out.

[0030] A breathable and waterproof membrane 12 is laminated to the back of the base fabric layer 11. The breathable and waterproof membrane 12 is made of bio-based polyester material, with a thickness of 10–20 micrometers and a breathability of not less than 500 g / m² / 24h. The breathable and waterproof membrane 12 has a porous nonwoven structure with interconnected microchannels inside, which can effectively prevent liquid water penetration while allowing water vapor to pass through, thus achieving excellent waterproof performance while maintaining good breathability.

[0031] To further enhance the functionality and structural stability of the fabric, an intermediate connecting layer 14 is provided between the base fabric layer 11 and the breathable and waterproof membrane 12. The intermediate connecting layer 14 is a hot melt adhesive film with an open-pore structure, used to enhance the interlayer bonding force and maintain the overall breathability. An antibacterial layer 15 is embedded inside the intermediate connecting layer 14. The antibacterial layer 15 is a porous film containing silver ions and is integrally formed with the intermediate connecting layer 14 during the manufacturing process. This gives the composite structure both adhesive function and antibacterial properties, effectively inhibiting bacterial growth and extending the service life of the fabric.

[0032] In addition, a hydrophilic functional layer 13 is provided on the surface of the base fabric layer 11. The hydrophilic functional layer 13 is composed of one or more of polyvinyl alcohol, chitosan or hydroxyethyl cellulose, and has a porous mesh structure. It covers the fiber surface of the base fabric layer 11 and forms a continuous moisture-wicking path with the microporous structure 111, further improving the fabric's moisture absorption and perspiration wicking ability and wearing comfort.

[0033] In summary, the lightweight, breathable, and environmentally friendly viscose-textured fabric of this utility model operates on the following principle: The base fabric layer 11 is a blend of warp yarns 112 and weft yarns 113, with a microporous structure 111 on its surface, formed by laser perforation. Both the warp yarns 112 and weft yarns 113 are hollow fibers, with internal moisture-wicking channels connected to the microporous structure 111, forming a three-dimensional moisture-wicking system. A breathable and waterproof membrane 12 is laminated to the back of the base fabric layer 11, with a hot-melt adhesive film containing a silver ion antibacterial layer 15 in the middle, and a hydrophilic functional layer 13 covering the surface, achieving efficient moisture absorption and wicking, waterproofing and antibacterial properties, and a comfortable wearing experience.
