Description

Technical Field

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

[0002] With the rapid development of the textile industry, blended fabrics, due to their ability to combine the excellent properties of multiple fibers, have become mainstream products in the current textile market and are widely used in clothing, home textiles, and industrial textiles. However, the chemical properties of the fibers constituting blended fabrics differ significantly, posing extremely serious challenges to their recycling and reuse. Traditional physical recycling methods such as mechanical opening and carding can only achieve fiber mixing and crushing, while methods using chemical solvents or enzyme treatments are complex, energy-intensive, and require large amounts of chemicals. This not only makes recycling costly but may also generate new chemical pollutants during the process, causing secondary harm to the environment, which contradicts the development concept of a green circular economy. Therefore, an innovative solution is needed that can avoid or bypass the complex and environmentally unfriendly separation and purification process, directly achieving efficient and environmentally friendly reuse of waste blended fabrics. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a green and environmentally friendly fabric that can effectively utilize waste blended fabrics and solves the problems of low utilization rate, high cost and environmental unfriendliness when recycling waste blended fabrics.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A green and environmentally friendly fabric with a multi-layer structure, consisting of a bottom layer, a functional layer, a sealing layer, and a top layer from bottom to top.

[0006] The functional layer comprises two layers of polyester staple fiber, with several pearl cotton support strips arranged sequentially at equal intervals between the two layers of polyester staple fiber. Each pair of pearl cotton support strips forms a group, and the two layers of polyester staple fiber between two adjacent pearl cotton support strips in the same group are stretched to form a filling bladder. The two layers of polyester staple fiber between two adjacent pearl cotton support strips in different groups are closed and sewn together to form a filling groove. The filling bladder is filled with recycled blended fiber wadding, and the filling groove is filled with memory foam particles.

[0007] Furthermore, antibacterial powder is dispersed inside the recycled blended fiber filler, and the antibacterial powder is a nano silver / zinc composite antibacterial powder.

[0008] Furthermore, a fiberglass mesh is laid at the opening of the filling groove. The fiberglass mesh is coated with water-based pressure-sensitive adhesive through an impregnation process, and the fiberglass mesh covers the memory foam particles inside the filling groove.

[0009] Furthermore, the cross-section of the pearl cotton support strip is circular or square.

[0010] Furthermore, the recycled blended fiber filler is a mixture of recycled polyester-spandex blended fiber filler and recycled nylon-spandex blended fiber filler.

[0011] Furthermore, the sealing layer is a polypropylene meltblown nonwoven fabric layer, and the sealing layer is bonded to the polyester short fiber layer in the functional layer.

[0012] Furthermore, the surface layer is a polyester fiber layer, and the surface layer is fixedly connected to the sealing layer by a mesh-like biodegradable hot melt adhesive.

[0013] Furthermore, the bottom layer is a thermoplastic polyurethane layer, and the bottom layer is bonded to the polyester short fiber layer in the functional layer.

[0014] The beneficial effects of this utility model are as follows: This solution achieves high-value and resource-based utilization of difficult-to-recycle blended textile waste. By directly using waste polyester-spandex, nylon-spandex, and other blended fabrics as filling material after crushing and opening, the complex fiber separation process in traditional recycling is perfectly avoided, significantly reducing recycling costs and energy consumption. This provides an economical and feasible recycling path for textile waste, reducing the environmental pressure from waste landfill and incineration at the source, and has significant environmental benefits. Simultaneously, the fabric of this solution, through a unique multi-layered composite structure of filling pouches and filling grooves, organically combines the fluffy elasticity of recycled fiber wadding with the slow rebound support of memory foam particles, giving the product excellent cushioning comfort, breathability, and durability.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] A green and environmentally friendly fabric, such as Figure 1As shown, the fabric has a multi-layer structure, comprising, from bottom to top, a bottom layer 1, a functional layer, a sealing layer 2, and a top layer 3. In this embodiment, the fabric is used to make products such as carpets and floor mats.

[0019] The bottom layer 1 is a thermoplastic polyurethane layer, which provides waterproof, moisture-proof and barrier functions against ground bacteria.

[0020] The functional layer comprises two polyester staple fiber layers 4, with a plurality of pearl cotton support strips 5 arranged sequentially at equal intervals between the two polyester staple fiber layers 4. The cross-section of the pearl cotton support strips 5 is circular or square; in this embodiment, a circular cross-section is selected. Each pair of pearl cotton support strips 5 forms a group. The two polyester staple fiber layers 4 between two adjacent pearl cotton support strips 5 in the same group are stretched apart to form a filling sac 6; the two polyester staple fiber layers 4 between two adjacent pearl cotton support strips 5 in different groups are closed and sewn together, forming a filling groove 7 at the closure point.

[0021] The filling bladder 6 contains a recycled blended fiber wadding 8, which is made from recycled broken blended fiber wadding. In this embodiment, a mixture of recycled polyester-spandex blended fiber wadding and recycled nylon-spandex blended fiber wadding is selected. The mixture of recycled polyester-spandex blended fiber wadding and recycled nylon-spandex blended fiber wadding is adjusted by mixing weight ratio to achieve different balances of elasticity and support.

[0022] Recycled blended fiber flakes are mainly collected from scraps and waste textiles from garment factories or similar blended waste clothing from sorting centers. Large pieces of fabric are broken into smaller pieces (approximately 5cm x 5cm) using a coarse shredder for easier subsequent processing. The shredded fabric pieces are then sterilized with high-temperature steam or soaked in environmentally friendly disinfectants to remove stains, grease, and microorganisms. They are then washed and dehydrated to obtain clean fabric fragments. These clean fabric fragments are then fed into a multi-compartment blending machine and a fine opening machine. Through the mechanical action of high-speed cylinders and rollers, the warp and weft yarns of the fabric are broken and opened, ultimately breaking down the blended fabric and restoring it to a loose, short fiber structure. This process requires precise control of the force to ensure the opening effect while avoiding excessive damage to the fiber length, resulting in a fluffy, interwoven blend of fibers. Different batches of opened blended fibers are then fed into a large blending silo for thorough and uniform mixing to stabilize the overall performance of the final product. If necessary, the fibers can be air-fluffed to fully expand the fiber bundles, increase the internal still air content, and thus significantly improve the warmth retention and compression resilience of the fiber fibers.

[0023] Antibacterial powder, specifically nano-silver / zinc composite antibacterial powder, is dispersed within the recycled blended fiber filler 8. The addition amount is 0.5%-2% of the total fiber weight, effectively preventing odors and health problems caused by microbial growth. During the fiber opening and combing process, the antibacterial powder is evenly sprayed into the fiber stream at a precise ratio. Due to the electrostatic effect of the fibers, the powder adheres to the fiber.

[0024] Memory foam particles 9 are placed inside the filling groove 7, and fiberglass mesh 10 is laid at the opening of the filling groove 7. The fiberglass mesh 10 is impregnated with water-based pressure-sensitive adhesive and then dried.

[0025] The sealing layer 2 is a polypropylene meltblown nonwoven fabric layer, which is bonded to the polyester short fiber layer 4 in the functional layer, and also bonded to the fiberglass mesh 10. The polypropylene meltblown nonwoven fabric layer has a dense microporous structure, which can effectively prevent the upward migration and leakage of powder and fiber lint in the functional layer, while allowing air and moisture to pass through.

[0026] The surface layer 3 is a polyester fiber layer, which is fixedly connected to the sealing layer 2 by a mesh-like biodegradable hot melt adhesive.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
