The present invention relates to a breathable disposable hygiene product and a gas circulation device comprising the same.

Hygiene products such as diapers and sanitary napkins have been used for a long time by various users of all ages. For example, fabric diapers such as cotton and small intestines have been used from the long past, and suitable materials and functions have been subdivided to solve the limitations of cotton fabrics and developed into present complex hygiene products.

Disposable hygiene products represented by diapers and sanitary napkins have contributed to improving the quality of life of users. In addition, as the average lifespan is increasing, the adult diaper market is growing, and adult diapers have become a major product that supports the lives of the elderly and patients.

Disposable sanitary products currently on the market may provide quick wearing and convenience of post-processing. Accordingly, the usage of disposable hygiene products has gradually increased. The main materials used for disposable hygiene products include non-woven fabrics, super absorbent polymers, and moisture-permeable films. Among the materials constituting the diaper, the non-woven fabric is mainly used as a surface material in direct contact with the skin. The wet-laid nonwoven fabric including rayon and pulp has a problem in that strength decreases when wet. A dry nonwoven fabric including an adhesive may cause a decrease in flexibility due to an adhesive component. Currently, spunbond, spunlace, and thermalbond nonwoven fabrics using polyolefin-based materials are mainly used as nonwoven materials, and the weight and strength have been increased. Super Absorbent Polymer (SAP) is a material for absorbing defecation and menstrual blood, and polyacrylate-based polymers with very high absorption and retention capacity compared to conventional absorbent paper or cotton pulp are mainly used.
