BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic structural diagram of the high-density polyester-nylon composite fiber cloth involved in the present utility model;

[0012] In the figure: 1-first fabric layer, 2-second fabric layer. DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1

[0015] Combine Figure 1 This embodiment is described in detail. A high-density polyester-nylon composite fiber cloth comprises a first fabric layer 1 and a second fabric layer 2, which are laminated together. The first fabric layer 1 is composed of polyester-nylon composite fiber filaments as the warp and cool nylon fiber filaments as the weft. The first fabric layer 1 has a warp density of 700-800 yarns / 10cm and a weft density of 550-650 yarns / 10cm. The second fabric layer 2 is composed of antibacterial yarn as the warp and mosquito-repellent yarn as the weft. Specifically, in this embodiment, the first fabric layer 1 has a warp density of 700 yarns / 10cm and a weft density of 550 yarns / 10cm. Specifically, the first fabric layer 1 and the second fabric layer 2 are laminated together using a dot-shaped hot melt adhesive.

[0016] Polyester-nylon composite fiber is made from polyester and polyamide. The two polymers are melted separately by two screw extruders, passed through the respective flow channels of the composite spinneret assembly, and then combined at the spinneret entrance for extrusion. Generally, the fiber is made of nylon as the sheath and polyester as the core. The resulting fiber combines the advantages of nylon and polyester, with good elasticity and wear resistance.

[0017] The cooling nylon filaments are made by blending 9% of ice-cool jade nanopowder into the nylon spinning solution, resulting in a permanent cooling sensation. Specifically, the cooling nylon filaments have a cross-shaped cross-section and numerous micropores on the fiber surface, which rapidly wick away moisture and perspiration, keeping the skin cool and dry.

[0018] Furthermore, the first fabric layer 1 is a variable satin weave; the second fabric layer 2 is a plain weave or twill weave. In this embodiment, the first fabric layer 1 is a warp-face double-weft satin weave, and the second fabric layer 2 is a plain weave. Satin weave fabrics have the advantages of being smooth, even, lustrous, and soft.

[0019] Furthermore, the antibacterial yarn is a polyester fiber filament modified with tea active ingredients. The polyester fiber filament modified with tea active ingredients adopts molecular nest technology to load and protect the catechin active ingredients in tea, mixes with ordinary polyester chips, adds dispersants and antioxidants, and is prepared by mixing and spinning. The molecular nest is made of mesoporous silica material with a diameter of about 100nm. It has the advantages of good porosity, large specific surface area, and easy modification. The use of molecular nests to carry and protect active ingredients extracted from natural plants can give the modified fiber biological activity, with the characteristics of long-lasting efficacy, green environmental protection and safety. Catechins, as the main active ingredients in tea, include catechin, gallocatechin, epicatechin, etc., which have multiple effects such as antibacterial, antiviral, anti-oxidation, anti-tumor, and immune regulation. The tea active ingredient modified polyester fiber filament has good antibacterial, antiviral and antioxidant activities, with an antibacterial rate of 91-99% against three standard strains of Staphylococcus aureus, Escherichia coli and Candida albicans, an antiviral rate of 99.51% and a free radical scavenging rate of 51.39%.

[0020] Furthermore, the anti-mosquito yarn is an antibacterial mosquito-repellent cotton fiber yarn. The antibacterial mosquito-repellent cotton fiber is prepared by adding a mixture of plant essential oil microcapsules, neem fruit, and green tea extract to a certain concentration, and then adding it to pretreated cotton fibers for special treatment. The antibacterial mosquito-repellent cotton fiber showed inhibition rates of 98.60% and 95.42% against Staphylococcus aureus after 0 and 20 washes, respectively; inhibition rates against Escherichia coli were 97.22% and 93.51%, respectively; and inhibition rates against Candida albicans reached 95.34% and 90.46%, demonstrating excellent antibacterial activity and washability. This is because the antibacterial mosquito-repellent cotton fiber contains neem fruit, green tea extract, and a mixed essential oil in or on its surface. This functional fiber has strong antibacterial properties and exhibits a strong inhibitory effect on bacteria. After washing the cotton fiber once, it had a repellent rate of 78.80%, demonstrating a strong repellent effect. After 20 washes, the repellent rate reached 47.80%, maintaining its effectiveness. This is because both the essential oil blend and the neem fruit extract possess potent mosquito repellent properties, contributing to the strong repellent effect before washing. After 20 washes, despite significant loss of the essential oil blend and neem fruit extract, the cotton fiber still maintained its repellent effect.

[0021] Example 2

[0022] The difference from Example 1 is that the mosquito-repellent yarn is made of mosquito-repellent polyester fiber yarn. The mosquito-repellent polyester fiber is produced using a melt-spinning method using mosquito-repellent masterbatch and polyester chips as the main raw materials. When the mosquito-repellent masterbatch content is 8%, the mosquito repellency rate reaches 38.33%, demonstrating mosquito repellency while maintaining the basic wearability of the polyester fiber.

[0023] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
