The technical scheme is not only suitable for a wide range of people, but also optimized according to different age groups and body types, and aims to reduce the risk of female breast diseases and improve the daily wearing experience of women.

Description

[0001] The present invention proposes a 3D super-breathable bra made of EAC thermoplastic elastomer material and through a precision thermoforming process. Its core value lies in the revolutionary improvement of the health, comfort and environmental performance of women's underwear. Through the unique grid-like multi-layer structure design, it achieves excellent breathability and strong support micro-elasticity, effectively solving the problems of traditional bras being stuffy and airtight, while using silk materials to enhance skin-friendliness and antibacterial effects. The present invention also focuses on the personalized adaptation of the product, adopts a diversified model design to meet the needs of different body shapes, and combines ergonomic design to ensure the precise support and comfortable fit of the bra. More importantly, the PET / EAC materials used and their products can be recycled, actively responding to the global initiative for sustainable development and providing women with a new choice of underwear that is safe, healthy, environmentally friendly and highly comfortable.

[0002] 3D super breathable bra materials and thermoforming technology

[0003] This technology utilizes existing materials through thermoforming to create new bra products. It aims to create bras that are more breathable, lighter, and retain their shape, while also being more aesthetically pleasing and beneficial to women's health. Furthermore, the materials are recyclable, making them more environmentally friendly.

[0004] The 2018 "China Women's Health Pink Report" has been released. Data was collected from 2,004,093 adult women nationwide, representing over 20 cities and spanning a dozen industries. The report shows that the peak rate of abnormalities detected on breast ultrasound (excluding breast hyperplasia) occurs in the 41-50 age group. "The majority of our clinical patients are women over 40," said Xu Xliang, deputy director of the Breast Center at Chongqing Cancer Hospital. New cases of breast cancer in my country have continued to increase in recent years. The 2017 "China Cancer Registry Annual Report" published by the National Cancer Center shows that the incidence rate of breast cancer in my country is 28.42 per 100,000 people, with approximately 279,000 new cases each year, increasing at an annual rate of 2% to 2.5%. Breast cancer is also becoming younger. Compared to Europe and the United States, the peak age of breast cancer in my country is approximately 10 years earlier, with the peak age of onset being between 45 and 55 years old.

[0005] Taking this hospital as an example, 30% of the breast cancer patients admitted to the hospital's breast center are under 40 years old.

[0006] Faced with this common problem, is there any way to improve the incidence of breast diseases in women? The answer is yes. By analyzing common bra products, we can get several key points:

[0007] First, the lack of breathability. Existing bra products are generally stuffy, have poor perspiration and moisture absorption effects, and are prone to breeding bacteria and producing sweat odor.

[0008] The second is poor fit, including insufficient wrapping resulting in a tight fit, or being too loose and lacking support, or being easily deformed and shifted;

[0009] Third, the fiber materials are unqualified or inappropriate, including the use of banned chemical fiber materials, fiber materials that cannot come into contact with the human body, and seriously insufficient fiber content.

[0010] Through the above analysis, the problem that this technical method aims to solve is very clear. That is:

[0011] 1. Improve breathability;

[0012] Second, by utilizing the material's inherent elasticity and appropriate hardness, we can design more models to accommodate different body sizes and address support and fit issues.

[0013] 3. Silk material is used in the part that is close to the skin to provide better compatibility with the human body, further enhance comfort, make it more permeable to sweat, and inhibit bacteria, providing all-round care for women's breast health.

[0014] The material properties of PET / EAC (thermoplastic elastomer) are used to make porous / multi-layer supported 0.2-1.2 cm thick grid-like PET / EAC sheets using melt extrusion, continuous lamination, vacuum forming and other technologies.

[0015] Secondary thermoforming requires dedicated machines and technical methods to ensure that the material properties are optimally utilized while maintaining its structural stability and functionality.
