Description

Technical Field

[0001] This utility model relates to the field of mesh fabric technology, and more specifically to a biodegradable mesh fabric. Background Technology

[0002] Mesh fabric, as a lightweight and highly breathable textile material, is widely used in functional parts of clothing (such as sportswear, T-shirts, and yoga wear) and footwear (such as athletic shoes and casual shoes), including uppers, linings, and underarm seams. However, in recent years, with the increasing global awareness of environmental protection and the implementation of plastic bans, the widespread use of traditional non-degradable synthetic fiber mesh fabrics in clothing and footwear has caused serious environmental problems. These materials generate microplastic pollution during production, use, and disposal, and are difficult to degrade in the natural environment, exacerbating soil and water pollution and increasing the ecological burden. Especially in the footwear and apparel industry, where mesh fabric is a core material for shoe uppers, insoles, and garment linings, the annual consumption is enormous, and its environmental threat after disposal is increasingly prominent. Therefore, it is now necessary to use biodegradable and environmentally friendly materials to manufacture mesh fabrics.

[0003] As shown in the prior art published in CN217597985U, although the prior art can make the mesh fabric antibacterial and breathable through the antibacterial layer, making it more comfortable to use; the combination of the first and second mesh fabric layers allows for degradation, resulting in an environmentally friendly effect; the addition of the alginate fiber layer increases the moisture absorption of the mesh fabric and facilitates its degradation, further enhancing its environmental benefits; and the inclusion of an abrasion-resistant layer increases its wear resistance and lifespan. However, the multiple layers in this prior art increase surface roughness, leading to a decrease in anti-snagging ability and making the mesh fabric more prone to snagging. This, in turn, affects the performance and lifespan of the mesh fabric in this technical solution. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a biodegradable mesh fabric. By placing the inner core in the center and protecting it from the middle and outer cores, a multi-layered composite mesh fabric structure is achieved. The outer middle and outer cores protect the inner core from being snagged by external objects, preventing the mesh fabric from becoming loose and damaged. At the same time, the wear-resistant layer separates the inner core, middle core, and outer core, thereby reducing friction and achieving the effects of protecting the mesh fabric and extending its service life, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biodegradable mesh fabric, comprising a mesh fabric woven from ropes;

[0006] The rope body includes an inner core, a middle core, and an outer core. The middle core and the outer core are both sleeved on the outside of the inner core. A wear-resistant layer is provided on the outside of the inner core, the middle core, and the outer core. Through the staggered winding of the inner core, the middle core, and the outer core, a multi-layer composite mesh structure can be achieved. The outer middle core and the outer core protect the inner core from being snagged by external objects, preventing the mesh from becoming loose and damaged. At the same time, the wear-resistant layer can separate the inner core, the middle core, and the outer core, thereby reducing friction and achieving the effect of protecting the mesh and extending its service life.

[0007] In a preferred embodiment, the inner core and outer core are spirally interwoven around the outside of the inner core, thereby placing the inner core in the middle and protecting it from the inner and outer cores, thus realizing a multi-layer composite mesh structure. The outer core and outer core protect the inner core from being snagged by external objects, preventing the mesh from becoming loose or damaged.

[0008] In a preferred embodiment, the inner core is made of bamboo fiber material. Bamboo fiber is naturally degradable, reducing environmental pollution. In addition, bamboo fiber has a hollow and porous structure, which has strong moisture absorption and can quickly absorb and evaporate sweat to keep you dry.

[0009] In a preferred embodiment, the core comprises polylactic acid (PLA) filaments and polyadipate filaments, which are spirally interwoven. The PLA filaments are derived from plant starch, and the polyadipate filaments are also biodegradable materials. The combination of the two can achieve natural degradation, thereby reducing environmental pollution. Furthermore, the PLA filaments and polyadipate filaments can make the mesh fabric lightweight and comfortable, effectively improving the comfort of using the mesh fabric and enabling the mesh fabric to maintain its shape stability during long-term use, thus improving the durability and practicality of the mesh fabric.

[0010] In a preferred embodiment, the outer core comprises chitin fiber filaments and polybutylene succinate fiber filaments, which are spirally intertwined and woven together. After the chitin fiber filaments and polybutylene succinate fiber filaments are combined, the mesh fabric can have the skin-friendly properties of natural materials and the durability of synthetic fibers, thereby improving the practicality and comfort of the mesh fabric.

[0011] In a preferred embodiment, the wear-resistant layer is made of polyurethane, which has excellent abrasion and wear resistance, effectively protecting the mesh substrate and extending its service life. Furthermore, while enhancing wear resistance, the polyurethane material does not significantly reduce the flexibility of the mesh, maintaining the fabric's bendability and conformability.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By placing the inner core in the center and protecting it from the middle and outer cores, a multi-layered composite mesh structure is achieved. The outer middle and outer cores protect the inner core from being snagged by external objects, preventing the mesh from becoming loose or snagged. At the same time, the wear-resistant layer separates the inner, middle, and outer cores, thereby reducing friction and protecting the mesh and extending its service life. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Refer to the instruction manual appendix Figure 1-5 This utility model provides a biodegradable mesh fabric, including a mesh fabric 5 woven from rope; the rope includes an inner core 1, a middle core 2 and an outer core 3, the middle core 2 and the outer core 3 are both sleeved on the outside of the inner core 1, and a wear-resistant layer 4 is provided on the outside of the inner core 1, the middle core 2 and the outer core 3.

[0022] The aforementioned rope is used to weave a mesh fabric 5. The rope comprises an inner core 1, a middle core 2, and an outer core 3. The middle core 2 and outer core 3 are spirally interwoven around the outer surface of the inner core 1, placing the inner core 1 in the center and protecting it from the middle core 2 and outer core 3. This achieves a multi-layered composite mesh fabric 5 structure. The outer middle core 2 and outer core 3 protect the inner core 1 from being snagged by external objects, preventing the mesh fabric 5 from becoming loose or damaged. Furthermore, wear-resistant layers 4 are provided on the outer surfaces of the inner core 1, middle core 2, and outer core 3. These wear-resistant layers enhance the stability and tensile strength of the inner core 1, middle core 2, and outer core 3, forming a protective layer on their surfaces. This prevents the inner core 1, middle core 2, and outer core 3 from becoming loose and snagged, and also increases the strength at the nodes of the rope-woven mesh fabric 5, reducing the risk of fiber breakage and snagging.

[0023] To improve the comfort of the mesh fabric 5, the inner core 1 is made of bamboo fiber. Bamboo fiber is naturally biodegradable, reducing environmental pollution and meeting green environmental protection requirements. Furthermore, bamboo fiber contains the natural antibacterial substance "quercetin," which inhibits bacterial and fungal growth, reducing odor and mold. In environments prone to sweating, such as sports shoes and outdoor gear, it can reduce odor and material aging caused by bacterial proliferation. Simultaneously, bamboo fiber has a hollow, porous structure with strong moisture absorption, quickly absorbing and evaporating sweat to keep the wearer dry. This allows for the formation of dense, breathable micropores during the weaving of the mesh fabric 5, improving air circulation.

[0024] like Figure 2-4 As shown, to improve the structural stability of the mesh fabric 5 and to provide shielding and protection for the inner core 1, the inner core 2 includes polylactic acid fiber filaments 21 and polyadipate fiber filaments 22. The polylactic acid fiber filaments 21 and polyadipate fiber filaments 22 are spirally interwoven. The polylactic acid fiber filaments 21 are derived from plant starch, and the polyadipate fiber filaments 22 are also biodegradable materials. The combination of the two can achieve the effect of natural degradation, thereby reducing environmental pollution and realizing the concept of circular economy. At the same time, the polylactic acid fiber filaments 21 have a soft and skin-friendly feel, while the polyadipate fiber filaments 22 have excellent elasticity and resilience. The structure of the two can make the mesh fabric 5 lightweight and comfortable, thereby improving the comfort of using the mesh fabric 5, and also enabling the mesh fabric 5 to maintain shape stability during long-term use, improving the durability and practicality of the mesh fabric 5.

[0025] Furthermore, the outer core 3 comprises chitosan fiber filaments 31 and polybutylene succinate fiber filaments 32, which are spirally intertwined and woven together. The chitosan fiber filaments 31 can quickly absorb and evaporate sweat to keep the skin dry, and can also release natural moisturizing factors to prevent dryness. The polybutylene succinate fiber filaments have high elasticity and abrasion resistance, can be repeatedly stretched, and have good thermal stability, maintaining a uniform structure and not easily deformed. The combination of chitosan fiber filaments 31 and polybutylene succinate fiber filaments gives the mesh fabric 5 the skin-friendly properties of natural materials and the durability of synthetic fibers, thereby improving the practicality and comfort of the mesh fabric 5.

[0026] Meanwhile, to prevent damage to the inner core 1, middle core 2, and outer core 3 caused by friction, the wear-resistant layer 4 is made of polyurethane. Polyurethane has excellent abrasion resistance and wear resistance, effectively protecting the mesh fabric 5 substrate and extending its service life. Furthermore, while enhancing wear resistance, the polyurethane material does not significantly reduce the flexibility of the mesh fabric 5, maintaining the fabric's bendability and conformability. Simultaneously, the polyurethane coating forms a hydrophobic surface, resisting the penetration of rainwater, oil, and other liquids, keeping the mesh fabric 5 dry and clean.

[0027] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
