Traditional polyester filament fabrics generally have poor hygroscopicity because polyester does not contain hydrophilic groups, which limits their application in the field of outdoor clothing with high hygroscopicity requirements. There are problems such as the inner layer of the fabric feeling hard, poor moisture absorption and perspiration function, and insufficient elasticity. Therefore, it is necessary to develop a polyester cotton-feel stretch PU microporous functional fabric. Utility Model Content

[0011] In the figure: 1- waterproof and breathable layer, 2- antibacterial layer, 3- cotton-feel moisture-conducting layer. DETAILED DESCRIPTION

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

[0013] Combination Figure 1 The present embodiment is described in detail. A polyester cotton-feel stretch PU microporous functional fabric comprises: a waterproof and breathable layer 1, an antibacterial layer 2 and a cotton-feel moisture-conducting layer 3 which are compounded in sequence; the waterproof and breathable layer 1 is a PU microporous membrane; the antibacterial layer 2 is formed by interweaving a first warp yarn and a first weft yarn; the first warp yarn is a viscose fiber yarn of Folium Isatidis; the first weft yarn is an antibacterial elastic yarn; the cotton-feel moisture-conducting layer 3 is formed by interweaving a second warp yarn and a second weft yarn; the second warp yarn is a cotton-like polyester filament; the second weft yarn is a moisture-conducting elastic yarn; the cotton-feel moisture-conducting layer 3 is a two-up and two-down right twill weave. Specifically, the waterproof and breathable layer 1, the antibacterial layer 2 and the cotton-feel moisture-conducting layer 3 are compounded by a mesh hot melt adhesive.

[0014] Specifically, PU and dimethylformamide are continuously stirred at 60°C until completely dissolved to obtain a casting liquid; the liquid is sealed and allowed to stand for degassing, and then scraped on a dry and clean glass plate to form a uniform film with a thickness of 0.4 mm, and the glass plate is immediately immersed in a non-solvent for 24 hours; after the casting liquid is phase-separated and formed into a film, the obtained film is transferred from the glass plate to distilled water for immersion to extract excess solvent and non-solvent, and a PU microporous membrane is obtained, wherein the non-solvent can be water, methanol, ethanol or isopropanol. The PU microporous membrane has micropores with a diameter of 1μm-100μm, which can allow water vapor with a diameter of 0.004μm to pass through, but water droplets cannot pass through, and has waterproof and moisture permeability functions.

[0015] The isatis leaf viscose fiber is a fiber with antibacterial function made by adding a natural plant isatis leaf extract solution with antibacterial function into a spinning solution by a blend spinning method and according to a viscose fiber production process. The isatis leaf viscose fiber has a good inhibitory effect on Staphylococcus aureus, and the antibacterial rate can reach 93.8%.

[0016] Cotton-like polyester filament is a functional filament made by spinning two polyester filaments with different shrinkage rates after hydrophilic modification through multiple processes to achieve the cotton-like effect. On the one hand, cotton-like polyester filament makes up for the shortcomings of cotton fabrics such as easy wrinkling, easy deformation, and poor wear resistance. On the other hand, it also gives full play to the good weather resistance and shape retention of polyester itself, has excellent breathability, and has a certain cotton feel in appearance.

[0017] Furthermore, the moisture-conducting elastic yarn has spandex filaments as the core, and is spirally wound with cross-section cool nylon filaments on the outside.

[0018] Furthermore, the fineness of the cross-section cool nylon filament is 70D. The cool nylon filament is prepared by blending 9% of ice-cool jade nanopowder into the nylon spinning solution, so that the nylon fiber has a permanent cool feeling to the touch, and is a new generation of heat dissipation and cooling fiber. The fiber cross section is cross-shaped, and there are many micropores on the fiber surface, which can quickly absorb and conduct sweat, keeping the side close to the skin dry. Combined with the cotton-feeling moisture-conducting layer 3 being a two-up and two-down right twill weave, the side of the cotton-feeling moisture-conducting layer 3 that contacts the user can obtain both a good cotton feel and moisture-conducting and cool performance.

[0019] Furthermore, the antibacterial stretch yarn has spandex filaments as the core and antibacterial nylon fiber filaments are spirally wound on the outside.

[0020] Furthermore, the fineness of the antibacterial nylon fiber filament is 70D. The antistatic nylon fiber filament is made by mixing 5% of layered nano-silver antibacterial material into nylon 6 masterbatch slices and using blending spinning technology to make antibacterial fiber, which can prevent the generation of odor and has a lasting antibacterial function.

[0021] Because the PU microporous membrane is a polyurethane material, it also has the advantages of good elasticity and high lightness. The weft yarns of the antibacterial layer 2 and the cotton-feel moisture-conducting layer 3 are both made of elastic yarns, so that the fabric has elasticity along the weft direction. The clothing made therefrom is convenient for the wearer to move his limbs. Combined with the functions of the cotton-feel moisture-conducting layer 3 and the antibacterial layer 2, the polyester cotton-feel elastic PU microporous functional fabric is suitable for use in making outdoor clothing.

[0022] The preferred specific embodiments of the utility model are described in detail above. 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.
