[0012] The utility model is further illustrated in connection with the drawings and specific embodiments.
[0013] Embodiment one
[0014] In connection with Figure 1 A PET film composite fabric is specifically explained, and the PET film composite fabric comprises a first wear-resistant layer 1, a tear-resistant layer 2, an antibacterial and mildew-proof layer 3 and a second wear-resistant layer 4 arranged in sequence; the first wear-resistant layer 1, the tear-resistant layer 2, the antibacterial and mildew-proof layer 3 and the second wear-resistant layer 4 are compounded by point-shaped hot melt type PU glue; the first wear-resistant layer 1 is interwoven by first wear-resistant yarns; the tear-resistant layer 2 is a PET film; the antibacterial and mildew-proof layer 3 is interwoven by antibacterial and mildew-proof yarns; and the second wear-resistant layer 4 is interwoven by second wear-resistant yarns.
[0015] The PET film has high tensile strength and tear resistance, so that it can bear certain external force without being easily broken when used as a film material, and after being compounded with other fabric layers, the strength and durability of the whole fabric can be improved, the tear resistance is improved, the fabric is not easy to be damaged, and the service life is prolonged.
[0016] Further, the first wear-resistant yarns are bio-based nylon 510 fiber filaments. Compared with ordinary nylon 6 and nylon 66, the bio-based nylon 510 fiber filaments are lighter in quality and more comfortable to wear. The moisture regain of the bio-based nylon 510 is 2.5%, which is lower than 3.5%-5.0% of nylon 6 and 4.2%-4.5% of nylon 66, and is equivalent to that of polyester, so that the wearer is dry and comfortable. The bio-based nylon 510 has higher color fastness and better stability, and the boiling water shrinkage is only about 3%, which is lower than 8%-10% of nylon 6 and 6.8% of nylon 66. The bio-based nylon 510 also has the functions of high wear resistance and high heat resistance.
[0017] Further, the antibacterial and mildewproof yarn is an antibacterial and mildewproof formaldehyde-removing multifunctional viscose fiber yarn. The antibacterial and mildewproof formaldehyde-removing multifunctional viscose fiber is prepared by blending and spinning plant Chinese medicine chrysanthemum extract, goldthread extract and sweet orange oil microcapsule and zeolite micro-powder suspension with viscose spinning solution. The chrysanthemum extract, the goldthread extract and the sweet orange oil have good antibacterial and mildewproof properties, the zeolite micro-powder has good adsorption, and has good effect as a base material of a formaldehyde functional agent. The antibacterial and mildewproof formaldehyde-removing multifunctional viscose fiber has a 97.04% antibacterial rate on staphylococcus aureus, a 0-grade mildewproof level, and a 60.88% formaldehyde removal rate; after 20 times of washing, the multifunctional viscose fiber has an 84.87% antibacterial rate on staphylococcus aureus, and the mildewproof function can still reach the 0-grade, the formaldehyde removal rate reaches 65.45% after 10 times of washing, and after the fiber adsorbs formaldehyde to near saturation, the formaldehyde in the fiber can be dissolved in water or dissipated after washing or high-temperature (light) treatment, and is not left in the fiber, so that the formaldehyde can be repeatedly absorbed.
[0018] Further, the second wear-resistant yarn is an antibacterial polyamide fiber filament. The antibacterial polyamide fiber filament is prepared by mixing 5% layered nano-silver antibacterial material into polyamide 6 master batch slices and using blending and spinning technology. The antibacterial polyamide fiber filament can prevent odor, has persistent antibacterial function, and has good wear resistance of the polyamide itself.

Specifically, the hydrophilic and easy-to-clean finishing agent is a Fupu product, which is a modified polyether polyester. The hydrophilic and easy-to-clean finishing agent can cover more hydrophilic copolymer films on the surface of the fabric, and the perfect combination of hydrophilicity and oleophobicity can easily wash off the surface oil stains when the fabric is washed with water, so that the effect of easy-to-clean is achieved. The fabric attached with the hydrophilic and easy-to-clean finishing agent can remove the stains by water wiping to a certain extent.
