Abstract

The invention discloses a China-hemp blended surface layer material for hygienic products. The China-hemp blended surface layer material for the hygienic products comprises, by mass, 20-50% of China hemp fiber and 50-80% of one of or combination of raw cotton fiber, Lyocell fiber, viscose fiber, polyester fiber and the polypropylene fiber.

Description

technical field [0001] The invention relates to a hemp blended surface layer material for sanitary products and a preparation method thereof. The hemp blended surface layer material can be used as sanitary napkins, tampons, baby diapers, adult diapers, diapers, and urine-separating pads and other surface materials. Background technique [0002] According to the preliminary market survey, there are various materials used for sanitary napkins, baby diapers, and adult diaper surface materials, such as pure cotton, polypropylene, polyethylene, etc. Each has its own different characteristics. The pure cotton material uses natural cotton as the raw material, which has the characteristics of skin-friendly, soft, and non-irritating; chemical materials such as polypropylene and polyethylene have the characteristics of breathability and dryness. However, each has its own shortcomings. The dryness of pure cotton material is poor, and the feeling of humidity is obvious; chemical materi...
