Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile materials, in particular to an antibacterial and anti-ultraviolet cloth and a manufacturing method thereof. BACKGROUND

[0002] The function realization of the existing antibacterial and anti-ultraviolet cloth mainly depends on three technical paths: first, a finishing process is adopted to coat antibacterial agents (such as silver ion and copper ion antibacterial agents) and anti-ultraviolet agents (such as benzotriazole organic anti-ultraviolet agents and nano-TiO2 inorganic anti-ultraviolet agents) on the surface of the fabric, and the functional components are attached to the surface layer of the fabric through a chemical adhesive; second, a double-layer structure design is adopted, the outer layer realizes the anti-ultraviolet function through high-density fibers or a coating, and the inner layer realizes the antibacterial function through the dipping of antibacterial agents, and ordinary solvent-type adhesives are used for compounding between the layers; and third, a few products attempt to combine the functional components with the fibers, but most of them are treated by dipping and spraying after spinning, and the functional components are not deeply combined with the fiber body. The above-mentioned technologies are the mainstream schemes for realizing the composite functions of antibacterial and anti-ultraviolet in the industry, covering multiple application scenarios from civil textiles to industrial protective products. The existing technologies have the following defects: first, the safety hazard is prominent, the traditional metal ion antibacterial agent (silver ion and copper ion) is easy to accumulate on the human skin for a long time, which may cause contact dermatitis, allergy and other adverse reactions, and the metal ions will be left in the soil and water after being discarded, which will destroy the ecological balance; second, the washing resistance is insufficient, the functional components are mostly physically attached to the surface, and are easy to fall off due to friction and swelling during washing, and the antibacterial rate is usually reduced to below 80% after 20 times of washing, and the anti-ultraviolet performance (UPF value) is attenuated by more than 30%; third, the structure and function are not complementary, the middle layer of some multi-layer structure products only plays a basic supporting role and does not form a complement with the antibacterial and anti-ultraviolet functions, and the solvent-type adhesives used between the layers contain volatile organic compounds (VOC), which have environmental risks during production and use; fourth, the function durability is weak, the functional components cannot be deeply embedded in the fiber after finishing or spinning post-treatment, and the function is easy to fail due to friction and abrasion and environmental aging after long-term use, therefore, the present application proposes an antibacterial and anti-ultraviolet cloth and a manufacturing method thereof to solve the problems in the prior art. SUMMARY

[0003] In view of the above problems, the present application proposes an antibacterial and anti-ultraviolet cloth and a manufacturing method thereof, which uses a natural antibacterial component to replace the traditional metal ion antibacterial agent, the natural component has excellent biocompatibility, no risk of accumulation on the human skin, can be naturally degraded after being discarded, and avoids environmental residue pollution.

[0004] To achieve the objectives of this invention, the invention is implemented through the following technical solution: an antibacterial and UV-resistant fabric, comprising a UV-resistant outer layer, a reinforcing middle layer, and an antibacterial inner layer sequentially laminated from the outside to the inside, wherein the UV-resistant outer layer contains a nano-metal oxide coating, the reinforcing middle layer is a fiber structure layer with strength support and wear resistance, and the antibacterial inner layer contains natural antibacterial components; The UV-protective outer layer, the reinforced middle layer, and the antibacterial inner layer are bonded together using an environmentally friendly adhesive.

[0005] Further improvements are made in that: the nano-metal oxide is titanium dioxide (TiO2), zinc oxide (ZnO), or a mixture of the two; the UPF value of the UV-protective outer layer is >50, and the UVA transmittance (T(UVA)AV) is <5%.

[0006] A further improvement is that the natural antibacterial component is a chitosan derivative or a plant extract, wherein the plant extract is at least one of green tea extract, artemisia extract, and peppermint extract.

[0007] A further improvement is that the fiber material of the reinforcing intermediate layer is polyester fiber, nylon fiber, cotton fiber, or a blend of any two fibers; and the tensile strength of the reinforcing intermediate layer is ≥20N.

[0008] A further improvement is that the environmentally friendly adhesive is a water-based polyurethane adhesive, a water-based acrylic adhesive, or a water-based epoxy adhesive; the solid content of the environmentally friendly adhesive is 25%-35%, and it does not contain volatile organic compounds (VOCs).

[0009] A method for manufacturing an antibacterial and UV-resistant fabric includes the following steps: S1: To prepare the UV-protective outer layer, the nanoscale composite functional masterbatch is mixed with fiber raw materials, and then melt-spun into a base fabric. A nano-metal oxide coating is then formed on the surface of the base fabric to obtain the UV-protective outer layer. S2: To prepare the reinforcing interlayer, select fiber materials, weave them into shape, and then perform heat setting treatment to produce the reinforcing interlayer. S3: To prepare the antibacterial inner layer, the nanoscale composite functional masterbatch is mixed with fiber raw materials and melt-spun into a base fabric. Natural antibacterial components are then loaded onto the surface of the base fabric to obtain the antibacterial inner layer. S4: Composite molding, using environmentally friendly adhesive to sequentially stack the UV-resistant outer layer, the reinforcing middle layer, and the antibacterial inner layer, and after curing treatment, to obtain antibacterial and UV-resistant fabric.

[0010] A further improvement is that the nanoscale composite functional masterbatch includes a functional component and a carrier resin; the functional component is at least one of nano-metal oxides and natural antibacterial components, and the functional component accounts for 10%-30% of the total mass of the nanoscale composite functional masterbatch; the carrier resin is at least one of PET resin and PA6 resin.

[0011] Further improvements are made in the following aspects: in S1 and S3, the melt spinning temperature is 180℃-270℃, the spinning speed is 1200m / min-1600m / min, and the basis weight of the base fabric is 80g / m²-150g / m².

[0012] The further improvement is that: in S1, the nano-metal oxide coating is formed by spraying, roller coating or scraping, and the coating thickness is 5μm-15μm; in S4, the curing temperature is 75℃-130℃ and the curing time is 25min-40min.

[0013] A further improvement is that, in S3, the natural antibacterial component is loaded by padding, spraying, or composite spinning; when padding is used, the concentration of the natural antibacterial component is 5%-10%, and the padding pressure is 0.2MPa-0.5MPa.

[0014] The beneficial effects of this invention are as follows: 1. This invention uses natural antibacterial components to replace traditional metal ion antibacterial agents. The natural components have excellent biocompatibility, no risk of accumulation on human skin, and can be naturally degraded after disposal, avoiding environmental pollution. Through a dual fixation method of melt spinning masterbatch and environmentally friendly adhesive, the natural antibacterial components are tightly bonded to the base fabric. After 50 washes, the antibacterial rate against Escherichia coli and Staphylococcus aureus remains above 95%, solving the core pain points of poor safety and insufficient washability of existing antibacterial fabrics.

[0015] 2. The fabric of this invention adopts a three-layer composite structure: an ultraviolet-resistant outer layer, a reinforcing middle layer, and an antibacterial inner layer. The outer layer achieves high-efficiency ultraviolet protection through a nano-metal oxide coating, blocking more than 95% of ultraviolet rays. The middle layer uses high-strength fiber materials, which significantly improves the fabric's tensile strength and abrasion resistance, extending its service life. The inner layer is loaded with natural antibacterial components, with an inhibition rate of >95% against Staphylococcus aureus and Escherichia coli. Each layer is composited with VOC-free environmentally friendly adhesive, eliminating environmental risks and achieving synergistic functions of ultraviolet protection, structural support, and antibacterial properties, solving the problems of loose structure and isolated functions in existing products.

[0016] 3. This invention breaks through the traditional surface-attached method of imparting function by deeply integrating nano-scale composite functional masterbatch with the fiber body during the melt spinning stage. This allows the antibacterial and UV-protective functional components to be evenly distributed inside and on the surface of the fiber, rather than simply adhering to the fabric surface. This fiber body-loaded structure can effectively resist water washing friction and long-term aging. Even after 50 water washings or 1000 friction tests, the functional component shedding rate is <5%, and the antibacterial and UV-protective functions decay by <5%, achieving a long-lasting and stable functional effect and solving the technical bottleneck of easy functional failure in existing products.
