[0002] Suits, also known as Western suits, are usually the first choice for corporate employees and government employees in more formal occasions. A key reason why suits have remained popular for so long is their rich history and cultural significance.
[0003] When people wear suits, their hands frequently come into contact with objects, making the cuffs of the suits prone to water stains and dirt. For example, food or soup may stick to the cuffs when eating at the table, or when people are carrying everyday items, the cuffs may also get stained. This affects the image of the person wearing the suit, and cleaning the water stains and dirt from the cuffs of the suit is quite tedious.
[0004] Traditional suit fabrics include worsted pure wool, woolen pure wool, cotton, and silk. As people's environmental awareness gradually increases, consumers' pursuit of sustainability and environmental protection is becoming more pronounced. Therefore, incorporating environmentally friendly materials and recycling elements into clothing design is not only a new fashion trend, but also reflects industry environmental awareness and corporate social responsibility.
[0005] Recycled polyester fiber is a synthetic fiber made from polyester waste such as waste plastic bottles and waste textiles through physical or chemical recycling processes. It is widely used in clothing, home textiles, automotive interiors and other fields.
[0006] Polylactic acid fiber is a fully biodegradable synthetic fiber that can be obtained from grains. When its products are discarded, they can be decomposed into carbon dioxide and water in soil or seawater through the action of microorganisms. When burned, it does not emit toxic gases or cause pollution. It is a sustainable ecological fiber.

[0025] This utility model embodiment provides a waterproof, stain-resistant, and environmentally friendly suit. The overall technical concept is as follows:
[0026] The outer surface of the suit jacket is made of recycled polyester fiber fabric, while the inner lining is made of polylactic acid fiber fabric, catering to consumers' pursuit of sustainability and environmental protection. Protective devices are installed at the cuffs of the sleeves to prevent water stains and dirt from getting into the cuffs. These devices are easy to use: simply pull the protective fabric out of the cuff, fold it over to cover the cuff, and Velcro fastens to secure it. The elastic thread is stretched. When the protective fabric is not needed, simply tear off the Velcro between the protective fabric and the cuff, and the elastic thread retracts, hiding the protective fabric inside the cuff, thus preserving the overall look of the suit.
[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0028] See Figures 1 to 6 The preferred embodiment of this utility model.
[0029] A waterproof, stain-resistant, and environmentally friendly suit, comprising:
[0030] The suit body has a surface 1 made of recycled polyester fiber fabric, a lining 2 made of polylactic acid fiber fabric, and sleeves 3 with protective devices at the cuffs of the sleeves 3.
[0031] The protective device includes an elastic thread 4, a protective fabric piece 5, and Velcro. The protective fabric piece 5 is connected to the inner wall of the sleeve 3 via the elastic thread 4. The cuff of the sleeve 3 is fixedly provided with the female side 6 of the Velcro. The outer side of the protective fabric piece 5 is fixedly provided with the female side 7 of the Velcro near the elastic thread 4. The outer side of the protective fabric piece 5 is fixedly provided with a drawstring 8 near the cuff. The inner side of the protective fabric piece 5 is covered with a waterproof and stain-resistant coating 9.
[0032] The beneficial effects or advantages of this utility model are as follows: The suit body is made of recycled polyester fiber fabric with environmentally friendly and sustainable characteristics; the lining is made of polylactic acid fiber fabric with natural, safe and skin-friendly characteristics, which helps the wearer feel comfortable; a protective device is set at the cuff of the suit body. When needed, the protective cloth of the protective device can be pulled out from the cuff and folded over to cover the cuff area to prevent the cuff area from getting wet and dirty. When not needed, the protective cloth can be pulled back into the cuff for concealment, which has the effect of waterproofing and stain resistance, improving the user experience of wearing the suit.
[0033] Polylactic acid (PLA) is a bio-based material extracted from renewable plant resources. Its natural and safe composition reduces the irritation of chemicals to the skin. PLA is derived from lactic acid, an endogenous substance in the human body with high biocompatibility and non-allergenicity. This means that products made from PLA fibers are less likely to cause allergic reactions upon skin contact, making them suitable for sensitive skin. The surface of PLA fibers exhibits a slightly acidic environment, which helps maintain the balance of microorganisms on the skin's surface, thus providing natural antibacterial protection.
[0034] When people wear suits and need waterproofing and stain protection at the cuffs, such as before carrying everyday items, they first grasp the pull strap 8 of the protective fabric piece 5 located inside one cuff. The pull strap 8 is easy for people to grip firmly with their fingers. People then pull the pull strap 8 outwards, thereby pulling the protective fabric piece 5. The elastic thread 4 is in a stretched state, pulling the protective fabric piece 5 out of the cuff. The bottom face 7 of the Velcro on the protective fabric piece 5 moves to the top face of the Velcro on the cuff, squeezing the bottom face 7 and the top face of the Velcro, thereby fixing the protective fabric piece 5 in place with the Velcro. After the protective fabric piece 5 is pulled out, it is folded over, covering the cuff area. The waterproof and stain-resistant coating 9, which was originally located on the inner side of the protective fabric piece 5, is exposed after the fold, effectively protecting the cuff area of the suit from getting dirty.
[0035] When people finish carrying everyday items and no longer need to protect the cuffs from water and stains, they can clean the waterproof and stain-resistant coating 9 of the protective fabric piece 5 with clean water, and then wipe it dry with a paper towel. During cleaning, the protective fabric piece 5 also prevents the cuffs from getting wet and also prevents damage to the cuffs when drying with a paper towel. After drying, turn the protective fabric piece 5 back so it doesn't cover the cuffs, and then peel off the front side 7 and the back side 6 of the Velcro. Under the retraction of the elastic thread 4, the protective fabric piece 5 is pulled back inside the cuff, thus concealing it. The waterproof and stain-resistant coating 9 increases the lifespan of the protective fabric piece 5.
[0036] Furthermore, the waterproof and anti-fouling coating 9 is composed of a nano-hydrophobic coating and an anti-oil coating.
[0037] The beneficial effects of this technical solution are as follows: The nano-hydrophobic coating uses a silica- or plant-based coating to form a hydrophobic layer on the fiber surface through a molecular-level structure, preventing water droplets from penetrating and causing them to roll off automatically, while maintaining the fabric's breathability and softness. The oil-resistant coating forms a surface texture similar to a lotus leaf, possessing strong surface tension and mimicking the oil-resistant function of a lotus leaf, making it difficult for liquid stains such as oil and coffee to adhere.
[0038] Furthermore, the protective fabric 5 is cylindrical, the female side 6 of the Velcro is annular, and the female side 7 of the Velcro is also annular.
[0039] The beneficial effects of this technical solution are: when a person is wearing a suit, their hands pass through the center of the cylindrical protective fabric piece 5. The female side 6 and the female side 7 of the hook and loop fastener can make more effective contact, thus connecting and securing them.
[0040] Furthermore, the plurality of elastic lines 4 are evenly spaced around the axis of the protective fabric 5.
[0041] The beneficial effects of this technical solution are: when the protective cloth 5 is pulled outward from the cuff, multiple elastic threads 4 work together to prevent a single elastic thread 4 from being pulled apart and damaged.
[0042] Furthermore, the female side 6 of the hook and loop fastener is a rough side, and the female side 7 of the hook and loop fastener is a barbed side.
[0043] This is a preferred product structure of the present invention.
[0044] In another embodiment of this invention, the outer surface of the suit body may also be covered with the waterproof and stain-resistant coating on other areas prone to contamination. Although the manufacturing cost is higher, the range of waterproof and stain-resistant properties is increased.
[0045] The protective devices at the cuffs of the suit sleeves not only prevent water stains and dirt from entering and contaminating the inner wall of the cuffs, but also help reduce friction damage to the cuffs during daily activities. The suit itself is made of environmentally friendly fabric, meeting consumers' pursuit of sustainability and environmental protection, and improving the user experience of wearing a suit.
[0046] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
