Technical Field

[0001] The present invention relates to the field of woolen sweaters, and particularly to a skin-friendly woolen sweater with ultraviolet protection function. Background Art

[0002] As a classic clothing category, woolen sweaters are deeply loved by consumers for their excellent warmth retention, comfort and natural texture.

[0003] With the increasing enthusiasm for outdoor activities among people, sun protection has become an important part of daily skin care. Traditional sunscreen products have problems such as easy shedding and skin irritation, while ultraviolet protection textiles provide a more durable and safe sun protection option. Wool, as a natural fiber, has excellent warmth retention, breathability and comfort, but its ultraviolet protection performance is weak. This project aims to develop a skin-friendly woolen sweater with ultraviolet protection function, combining the comfort of wool and the ultraviolet protection function to meet the dual needs of consumers for comfort and sun protection. Summary of the Invention

[0004] Aiming at the problems mentioned in the background art, the purpose of the present invention is to provide a skin-friendly woolen sweater with ultraviolet protection function to solve the problems mentioned in the background art.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions:

[0006] A skin-friendly woolen sweater with ultraviolet protection function, comprising: a support layer, one side of the support layer is connected with a wear-resistant protection layer, and the other side of the support layer is connected with a sweat-absorbing layer; an ultraviolet protection functional layer, the ultraviolet protection functional layer is arranged on the top surface of the wear-resistant protection layer; a skin-friendly comfort layer, the skin-friendly comfort layer is connected to the bottom of the sweat-absorbing layer.

[0007] By adopting the above technical solutions, by setting the ultraviolet protection functional layer, when the woolen sweater is in use, the user's skin directly contacts the skin-friendly comfort layer. The cashmere fibers on the skin-friendly comfort layer provide the user with extreme softness and skin-friendly feeling, reducing the irritation to the skin. The sweat-absorbing layer can quickly absorb the sweat on the skin surface and conduct it to the outer layer for evaporation. The skin-friendly comfort layer is a single-sided fleece structure, and the fleece treatment is carried out on the surface of the skin-friendly comfort layer to form soft fluff, increasing the contact area with the skin, improving the comfort level and the fluff structure can store air, enhancing the warmth retention. At the same time, the skin-friendly comfort layer and the sweat-absorbing layer are combined by dot bonding or knitting process to form a double-layer composite structure, improving the wearing comfort of the user. The ultraviolet protection functional layer absorbs and reflects ultraviolet rays, blocking UVA and UVB. The wear-resistant protection layer protects the ultraviolet protection functional layer from abrasion, prolonging the service life of the clothing and improving the practicality.

[0008] Preferably, one side of the wear-resistant protective layer is connected with a reflection enhancement layer, and one side of the reflection enhancement layer is connected to the bottom of the anti-ultraviolet functional layer.

[0009] By adopting the above technical solution, by setting the reflection enhancement layer, during use, the reflection and scattering of ultraviolet rays are enhanced through the reflection enhancement layer, reducing the penetration of ultraviolet rays. The anti-ultraviolet functional layer and the reflection enhancement layer adopt high-count yarns and a tight weaving process, reducing the ultraviolet transmittance, improving the durability and pilling resistance of the fabric. And taking the anti-ultraviolet functional layer and the reflection enhancement layer as the outer layer and the wear-resistant protective layer as the inner layer, the layered design ensures that each layer functions independently and synergistically. The inner layer protects the functional layer and extends the lifespan of the clothing. The reflection enhancement layer adopts a honeycomb structure, a mesh structure or a concave-convex structure to increase the ultraviolet reflection and scattering effect, enhancing the breathability and comfort of the fabric. The reflection enhancement layer and the anti-ultraviolet functional layer act synergistically to improve the overall UPF value.

[0010] Preferably, the anti-ultraviolet functional layer adopts nano-titanium dioxide and zinc oxide coated fibers, and synthetic fibers treated with an anti-ultraviolet finishing agent.

[0011] By adopting the above technical solution, by setting the anti-ultraviolet functional layer, the anti-ultraviolet functional layer can effectively absorb and reflect ultraviolet rays through nano-titanium dioxide and zinc oxide coatings, with a UPF value ≥, providing excellent ultraviolet protection, reducing the harm of ultraviolet rays to the skin, comprehensively blocking long-wave ultraviolet rays and medium-wave ultraviolet rays, preventing sunburn, skin aging and the risk of skin cancer. The nano materials are firmly attached to the fiber surface through coating and co-blending spinning processes and are not easy to fall off, and can still maintain high-efficiency anti-ultraviolet performance after multiple washes, being suitable for long-term use. The thickness of the nano coating and the functional fiber is relatively thin, not increasing the weight of the clothing, maintaining the lightness and good breathability of the clothing, avoiding a stuffy feeling, enhancing the wearing comfort, and nano-titanium dioxide and zinc oxide are environmentally friendly materials, harmless to the human body, safe and non-toxic, suitable for people with sensitive skin, meeting environmental protection standards, reducing environmental pollution. The anti-ultraviolet functional layer can be combined with waterproof and windproof functions to provide comprehensive outdoor protection, meeting the needs of various usage scenarios, and enhancing the practicality and added value of the clothing.

[0012] Preferably, the reflection enhancement layer adopts high-reflectivity fibers, and the wear-resistant protective layer adopts high-strength synthetic fibers.

[0013] By adopting the above technical solutions, by setting up a reflection enhancement layer, the high-reflectivity fibers can effectively reflect and scatter ultraviolet rays, reduce the penetration of ultraviolet rays, further improve the UPF value, and cooperate with the ultraviolet protection functional layer to provide dual protection and ensure an efficient sun protection effect. The reflection enhancement layer increases the reflection surface area through a special weaving process, improves the reflection efficiency of ultraviolet rays, and enhances the protection effect. The high-reflectivity fibers and the special weaving process keep the reflection enhancement layer thin and light. The high-reflectivity fibers and the special weaving process do not affect the color and texture of the fabric, maintain the aesthetics of the clothing, are suitable for designing various fashionable styles, and can achieve diversified designs through dyeing or printing processes. The reflection enhancement layer provides excellent sun protection performance for the ultraviolet protection woolen sweater through multiple beneficial effects such as enhancing the reflection and scattering of ultraviolet rays, increasing the overall UPF value, and increasing the reflection surface area. The high-strength synthetic fibers used in the wear-resistant protective layer have excellent wear resistance, effectively protect the ultraviolet protection functional layer from daily wear, extend the service life of the clothing. The high-strength synthetic fibers have high tear resistance, prevent the clothing from being damaged due to accidental tearing or snagging, and improve the durability of the clothing, making it suitable for high-intensity use scenarios. The surface of the wear-resistant protective layer is smooth, not easy to adhere to dirt, reduces the adhesion of dirt and dust, keeps the clothing clean, is easy to clean and maintain, and reduces the care difficulty. As an intermediate layer, the wear-resistant protective layer effectively protects the ultraviolet protection functional layer, prevents the functional layer from failing due to wear, and ensures long-term ultraviolet protection performance. The wear-resistant protective layer provides excellent protection performance for the ultraviolet protection woolen sweater through multiple beneficial effects such as excellent wear resistance, tear resistance, and easy cleaning.

[0014] Preferably, the sweat-absorbing layer is made of moisture-absorbing and sweat-wicking fibers, and the skin-friendly and comfortable layer is made of superfine Merino wool or cashmere fibers.

[0015] By adopting the above technical solutions, by setting up a sweat-absorbing layer, the moisture-absorbing and sweat-wicking fibers can quickly absorb the sweat on the skin surface and conduct it to the outer layer for evaporation, keeping the skin dry and avoiding discomfort caused by sweat accumulation. The moisture-absorbing and sweat-wicking fibers have good air permeability, promote air circulation, avoid a stuffy feeling, regulate body temperature, and are suitable for various climate conditions. The skin-friendly and comfortable layer uses superfine Merino wool or cashmere fibers with a diameter less than 18.5 microns, which have a delicate touch, provide extreme softness and skin-friendly feeling, reduce irritation to the skin, are suitable for skin-to-skin wearing, and improve wearing comfort. The natural protein structure has a good temperature and humidity regulation function, provides a warming effect in cold environments, and keeps cool in hot environments. The superfine Merino wool or cashmere fibers have natural antibacterial and odor-proof properties, inhibit the growth of bacteria, reduce the generation of odors, keep the clothing fresh, and are suitable for long-term wearing.
