[0010] Figure 1 This is a schematic structural diagram of the environmentally friendly and degradable warp knitted fabric involved in the utility model;

[0011] In the figure: 1- moisture conductive layer, 2- antibacterial layer, 3- easy-to-remove layer. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Embodiment 1

[0014] Combination Figure 1 The present embodiment is described in detail. An environmentally friendly and degradable warp knitted fabric comprises: a moisture-conducting layer 1, an antibacterial layer 2, and an easy-to-remove layer 3 which are compounded in sequence; the moisture-conducting layer 1, the antibacterial layer 2, and the easy-to-remove layer 3 are compounded by a mesh degradable hot-melt adhesive; the moisture-conducting layer 1 is warp-knitted from degradable moisture-conducting fiber yarn; the antibacterial layer 2 is warp-knitted from degradable antibacterial fiber yarn; the easy-to-remove layer 3 is warp-knitted from celis biodegradable fiber yarn; the easy-to-remove layer 3 is a warp-knitted twill mesh structure.

[0015] Specifically, the linear density of the Cylis biodegradable fiber yarn is 118dtex, and the twist is 91 twists / 10cm. Cylis biodegradable fiber is a polyester fiber that is added with a hydrophilic third monomer during the polymerization process to change the chemical structure to achieve biodegradable. The hydrophilic groups and pore structure of Cylis biodegradable fiber can enhance the hygroscopicity and moisture conductivity of the fabric; the pores of Cylis biodegradable fiber itself increase the specific surface area of ​​the fiber, which can accelerate the evaporation rate of fabric water and improve the moisture permeability; the hydrophilic groups and pore structure of Cylis biodegradable fiber make it excellent in hydrophilicity, so when the fabric meets water, Cylis biodegradable fiber interacts with water, the interfacial tension of the fiber / water phase is weak, and the interfacial tension of the oil stain / fiber phase is strong, and the oil stain is easily separated from the fabric through external mechanical action, achieving the effect of easy decontamination.

[0016] Specifically, the warp knitted twill mesh structure is woven by four combing bars, and the yarn numbers of the four combing bars are respectively,

[0017] GB1: 1-0 / 1-2 / 1-0 / 2-3 / 2-1 / 2-3 / / ,

[0018] GB2: 2-3 / 2-1 / 2-3 / 1-0 / 1-2 / 1-0 / / ,

[0019] GB3: 1-0 / 2-3 / / ,

[0020] GB4: 1-0 / 2-3,

[0021] GB1 and GB2 perform symmetrical padding movements, with a minimum flower height of six horizontal rows. GB3 and GB4 perform the same padding movement to form a twill mesh structure with a distinct mesh effect, making the fabric straight and wide, with a strong sense of concave and convex, and with good drape and breathability, making it suitable for skirts, jackets and other fabrics.

[0022] Furthermore, the degradable moisture-conducting fiber yarn is a cross-section polylactic acid fiber filament, and the specification of the cross-section polylactic acid fiber filament is 60-80D / 48F. Specifically, in the present embodiment, the specification of the cross-section polylactic acid fiber filament is 75D / 48F. Polylactic acid fiber is a plant-based polymer. The raw materials are extracted from starch in corn and cassava and sugar in sugarcane and beets. Lactic acid is obtained through fermentation and dehydration processes, and is made through polycondensation and melt spinning. It is a biodegradable material. Polylactic acid fiber has the functions of skin-friendly, breathable, moisture-conducting, etc., and has good biocompatibility. The cross section has four grooves in the longitudinal direction, which can reduce the contact points between the fiber and the skin, ensuring that the skin remains dry after sweating.

[0023] Furthermore, the degradable antibacterial fiber yarn is an antibacterial deodorizing hemp pulp fiber yarn. The antibacterial deodorizing hemp pulp fiber is made from hemp plants such as hemp stalks, jute, and kenaf, and a deodorant is added to the pulp to produce hemp pulp regenerated cellulose fiber. The antibacterial deodorizing hemp pulp fiber has natural antibacterial and mildew-proof properties, and acaricide and acarid repellent properties. Green production is implemented throughout the production process. During processing, not only is the cellulose extracted from jute and kenaf, but the natural antibacterial substances in jute and kenaf are also retained; the combustion of the deodorizing hemp pulp fiber can generate carbon dioxide and water, which is pollution-free to the environment. If the fiber is buried, a large number of bacteria in the soil can decompose the cellulose, and it can be completely degraded in 8 to 10 months, and has good biodegradability.

[0024] Embodiment 2

[0025] The difference from Example 1 is that the degradable moisture-conducting fiber yarn is twisted by bamboo fiber yarn and milk protein fiber yarn. Bamboo fiber is a fiber directly extracted from bamboo by a combination of physical and chemical methods. It is a natural fiber and has natural antibacterial and antimicrobial properties. It does not cause allergic reactions when people come into contact with bamboo fiber, and can also remove odors and drive away bacteria. Due to the porosity of the bamboo fiber structure, it has air permeability and hygroscopicity, and can absorb and evaporate water. Bamboo fiber has good biodegradability and can be buried in the soil for degradation, or it can be directly decomposed into carbon dioxide and water through chemical reactions. Milk protein fiber is a regenerated fiber that is different from natural fibers and synthetic fibers by extracting protein molecules from milk, reacting and grafting with the macromolecular compound polyacrylonitrile, and finally forming a regenerated fiber through wet spinning that is different from natural fibers and synthetic fibers. It has the advantages of both natural fibers and synthetic fibers and has good biodegradability. In addition to the many grooves and pores in the longitudinal and cross-sectional directions, the milk protein fiber contains a large number of hydrophilic groups on the fiber surface. When the fabric woven from the fiber is worn, human sweat will be quickly absorbed into the grooves of the fiber and then introduced into the air to evaporate, keeping the human skin dry and cool for a long time.

[0026] Embodiment 3

[0027] The difference from Example 1 is that the degradable antibacterial fiber yarn is a chitosan fiber yarn. Chitosan fiber is generally prepared by first dissolving chitosan raw material in an acetic acid solution, filtering and degassing to form a spinning solution of a certain viscosity, the solution is distributed to the spinning position along the pipeline, and then flows to the spinneret through a metering pump and a filter. After being pressed out of the spinneret, the thin stream of solution is coagulated into a solid fiber in a coagulation bath, and then further stretched and processed to obtain. After protonation, chitosan can undergo an electrical neutralization reaction with bacteria and has very good antibacterial properties. Chitosan fiber itself has excellent biocompatibility, degradability, broad-spectrum antibacterial properties, mildew resistance and deodorization properties, and the fabric woven into it has a good antibacterial effect.

It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
