Abstract

The invention discloses a water-resistant antibacterial bamboo fiber non-woven fabric surface layer and a preparation method thereof and belongs to the technical field of sanitary towel material preparation. The surface layer is prepared from, by weight, 90-96% of bamboo fibers, 2.5-5% of soybean protein fibers, 2.0-3.0% of corn protein fibers, 0.5-1.6% of sugarcane fibers, 0.2-0.8% of potato starch, 0.2-8% of wheat starch and 1-2.5% of water, wherein the materials above are subjected to mixing, heating, stirring, water-jetting and other processes to manufacture the surface layer. The surfacelayer contains no any additive component and is environmentally friendly and healthy; by adding natural plant fibers, starch and the like into the bamboo fibers, the hydrophobicity and softness of thebamboo fiber non-woven fabric surface layer are enhanced, and therefore the air breathability and water conducting performance are excellent.

Description

technical field [0001] The invention belongs to the technical field of sanitary napkin material preparation, and in particular relates to a water-resistant and antibacterial bamboo fiber non-woven surface layer and a preparation method thereof. Background technique [0002] At present, the basic structure of women's sanitary napkins on the market is "non-woven fabric (chemical synthetic fiber) surface layer + liquid-absorbing layer + plastic film leak-proof bottom layer". The surface layer is mainly made of high-molecular chemical synthetic fibers, which are made by bonding chemical fibers with adhesives in the production method of non-woven fabrics; or directly punched on the high-molecular film material. It is characterized by high wet strength, good softness and fast penetration. However, when used for a long time, some users will cause discomfort reactions such as skin spasm, itching and allergies, and at the same time, it will have a serious impact on the environment b...
