[0017] The present application also provides a garment made by a method for manufacturing antibacterial, deodorizing and waterproof functional garments.

[0018] Compared with the prior art, the present invention has the following beneficial effects: Through ultrasonic penetration and high-temperature curing treatment of natural plant extracts and nano-silver composite antibacterial agents, long-lasting antibacterial and deodorizing effects are achieved. At the same time, combined with the spraying and curing of modified polyurethane waterproof coating, it ensures that the clothing still has excellent waterproof and breathable properties after multiple washings, simplifying the process while improving functionality and durability.

[0019] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the attached picture: Figure 1 The present invention is a flow chart of a method for manufacturing antibacterial, deodorizing and waterproof functional clothing. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0022] like Figure 1 As shown, the present invention provides a method for manufacturing clothing with antibacterial, deodorizing and waterproof functions. It aims to solve the technical problems that the antibacterial, deodorizing and waterproof functions are difficult to integrate in the existing clothing manufacturing and the durability and comfort are insufficient. The method uses natural antibacterial materials and advanced coating technology to ensure that the clothing has excellent protective performance and comfort in various environments. The following are the detailed process steps.

[0023] S1. Substrate selection A blended fabric of polyester fiber and organic cotton is selected as the base material, wherein the blending ratio of polyester fiber to organic cotton is 70:30. Polyester fiber has excellent wear resistance, toughness and durability, and can provide the support and tensile strength required for clothing in outdoor environments; organic cotton provides a soft and comfortable touch and good breathability, making the clothing more suitable for close-fitting wear. In particular, the fiber diameter of the polyester fiber is 0.5 to 1.5 denier, which ensures the softness and breathability of the base material, and is suitable for sports and daily wear.

[0024] S2. Physical pretreatment of substrate Place the selected substrate in warm water at 60°C and add neutral detergent for 30 minutes to remove impurities, grease and dust on the fiber surface, and improve the cleanliness and affinity of the substrate surface. This step can provide a better adhesion basis for subsequent antibacterial treatment and waterproof coating, and help improve the stability and durability of the antibacterial and waterproof effects.

[0025] S3. Preparation and treatment of composite antimicrobial agents In order to achieve long-lasting antibacterial and deodorizing effects, a composite antibacterial agent is prepared. The antibacterial agent includes natural plant extracts, nanosilver and surfactants. Specifically, the liquid ratio of the composite antibacterial agent is: 94.4% water, 5% plant extracts, 0.1% nanosilver and 0.5% surfactant. The natural plant extracts are selected from tea tree oil or peppermint oil, both of which have natural antibacterial properties and fresh smells, and are particularly suitable for use in close-fitting clothing. The surfactant is sodium dodecylbenzene sulfonate, which can help the antibacterial agent to be evenly distributed on the fiber surface and form a stable coating.

[0026] S4. Ultrasonic treatment of antimicrobial agents The prepared composite antimicrobial agent is evenly coated on the substrate, and ultrasonic treatment technology is used to enhance the permeability of the antimicrobial agent. The frequency of ultrasonic treatment is 40 to 50 kHz, and the oscillation time is 15 to 25 minutes, which can drive the antimicrobial agent to penetrate into the tiny pores of the fiber, ensuring that the antimicrobial agent is firmly attached and evenly distributed inside and on the surface of the fiber. This treatment method not only improves the antimicrobial effect, but also enhances washability, so that the clothing can still maintain a lasting antimicrobial and deodorizing effect after multiple washings.

[0027] S5. Curing treatment The antibacterial treated substrate is placed in a drying oven at 80°C for 30 minutes to cure, so that the antibacterial agent components are more firmly attached to the surface and inside of the fiber. This process can further enhance the durability of the antibacterial effect and ensure that the antibacterial properties of the treated substrate are not easily lost during actual wear.

[0028] S6. Spraying treatment of waterproof coating The modified polyurethane waterproof coating is used to waterproof the substrate. The waterproof coating is a water-based polyurethane emulsion with low volatile organic compound (VOC) content, which meets environmental protection requirements. The mass percentage of the coating is 8%. When spraying, the equipment pressure is set to 0.4 MPa and the spraying distance is 15 cm to ensure the uniformity of the coating on the substrate surface. The modified polyurethane has excellent waterproof and breathable properties, and can effectively block external moisture penetration without affecting wearing comfort.

[0029] S7. Curing of waterproof coating The sprayed substrate is placed in an environment of 100°C for curing for 10 minutes. This step allows the waterproof coating to be firmly bonded to the surface of the substrate, forming a waterproof layer with long-term protective effect. This waterproof layer has excellent wear resistance under various wearing conditions, can effectively prevent moisture from entering the inside of the clothing, and is suitable for wearing in rainy or humid environments.

[0030] S8. Cutting and sewing Waterproof stitching technology is used in the sewing process of clothing, and waterproof tape is reinforced at the seams to improve the waterproof performance of the stitching parts. The waterproof tape is hot melt adhesive, and its thickness is controlled between 0.5 and 1.0 mm to ensure the waterproofness of the seams and prevent moisture from penetrating from the stitching position. At the same time, the hot melt adhesive material has good flexibility and durability, and can fit perfectly with the fabric seams, further improving the overall waterproof effect of the clothing.

[0031] S9. Performance test The finished garments were tested for antibacterial and waterproof properties. The antibacterial performance test complies with the national standard GB 4789.2, ensuring that the antibacterial rate is not less than 95%; the waterproof performance test complies with the international standard AATCC 22, and the test results show that the water column height of the garment is not less than 1500 mm. These test indicators show that the garments made by the present invention can still maintain excellent antibacterial and waterproof effects after being worn and washed for a long time.

[0032] The present invention also provides a functional garment manufactured by the above method. The garment is treated with multiple functions of antibacterial, deodorizing and waterproofing, and can provide long-lasting protection and comfortable wearing experience in different usage scenarios. The following is a description of the specific features and performance of the functional garment.

[0033] 1. Antibacterial function The clothing of the present invention adopts a composite antibacterial agent containing natural plant extracts and nanosilver, and after ultrasonic treatment and curing, the antibacterial agent is deeply embedded in the fiber, ensuring the uniform distribution of the antibacterial agent on the fiber surface and inside. The presence of the antibacterial agent enables the clothing to have a long-term inhibitory effect on a variety of bacteria and fungi. After testing, the antibacterial rate of the clothing reaches more than 95%, which meets the national standard GB 4789.2, and the antibacterial performance remains stable after multiple washings, effectively reducing the possibility of bacterial growth.

[0034] 2. Deodorizing function By combining natural plant extracts (such as tea tree oil or peppermint oil) into composite antimicrobial agents, clothing has a certain anti-odor effect while being antibacterial. The penetration and fixation of natural extracts in the fabric enables it to inhibit bacteria while reducing odor caused by bacterial growth. The addition of nanosilver further improves the anti-odor performance, effectively reducing the generation of odor even in high humidity or high temperature environments, maintaining a high degree of cleanliness and comfort.

[0035] 3. Waterproof function During the production process of the garment of the present invention, after spraying the modified polyurethane waterproof coating and curing at 100°C, a stable waterproof layer is formed on the surface of the substrate, which can effectively block the infiltration of external moisture. The waterproof coating has good air permeability, allowing internal moisture to be discharged while maintaining waterproof performance, so as to enhance the comfort of wearing. According to the AATCC 22 standard test, the water column height of the waterproof layer reaches 1500 mm, showing strong waterproof performance and durability.

[0036] 4. Application scenarios and functional stability Due to the multiple effects of the above antibacterial, deodorizing and waterproof treatments, the garment can be used in environments where it is worn for a long time, including outdoor activities, protective scenes and daily protection needs. The multiple functional treatments of the garment ensure the stability of its functions in hot and humid environments and under conditions of multiple washings, and the protective effect will not be significantly reduced due to use or washing.

[0037] In summary, the clothing made by the above detailed steps of the present invention has great effects in antibacterial, deodorizing and waterproof properties, and is particularly suitable for outdoor sports, medical protection and daily wear. The clothing can still maintain its functionality after multiple washings, indicating that the present invention has significant advantages in durability and comfort, meets consumers' demand for multifunctional and high-quality clothing, and has strong market application prospects.

[0038] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
