Abstract

The invention discloses a bio-antimicrobial water-absorbing sanitary material, which is applied to medical dressing materials, sanitary napkins, sanitary towels and paper diapers, and a preparation method of the bio-antimicrobial water-absorbing sanitary material. An antimicrobial liquid-permeable surface layer, an antimicrobial functional absorbent core and a liquid-impermeable bottom layer are sequentially arranged from top to bottom in a superposed mode, wherein the antimicrobial liquid-permeable surface layer is a single-layer or double-layer non-woven fabric which is processed by virtue of a bio-antimicrobial agent, and the bio-antimicrobial agent is one or more of epsilon-polylysine and / or epsilon-polylysine hydrochloride, natamycin and nisin; the antimicrobial absorbent core comprises the bio-antimicrobial agent which is one or more of epsilon-polylysine, epsilon-polylysine hydrochloride, natamycin and nisin, a polymer absorbent, fluff pulp and plant extracts; and a porous air-permeable thin film serves as a backing layer. The bio-antimicrobial water-absorbing sanitary material has the advantages of being good in antimicrobial endurance, broad in antimicrobial spectrum, high in biological safety and low in reverse osmosis rate.

Description

technical field [0001] The invention relates to a biological antibacterial water-absorbing sanitary material and a preparation method that can be applied to medical dressing materials, sanitary pads, sanitary napkins and paper diapers. Background technique [0002] Water-absorbing hygienic materials such as trauma hemostatic materials, sanitary pads, sanitary napkins, and diapers are widely used in patients, women, infants, and disabled people. Since water-absorbing hygienic materials are in direct contact with the skin and absorb body fluids, they can easily become a "culture medium" for bacteria to proliferate, resulting in an explosive increase in the number of microorganisms. Although water-absorbing sanitary materials can be sterilized or antibacterially treated on the surface of the product, the product can meet the microbial index control requirements before use, but the microorganisms can exceed the standard in a short time after use, which will pose a certain threat...
