Description
Technical field
The present invention relates to daily living article field, particularly a kind of preparation method of antibacterial ramie fiber, and the application on paper diaper, sanitary napkin.
Background technology
Current antiseptic has four large classes: inorganic antiseptic, organic antibacterial agent (chemistry), natural plants antiseptic and biological antibiosis agent.And in hygiene article sector, the antimicrobial technology mainly inorganic and organic anti-bacterial technology of application at present.But organic anti-bacterial mainly chemicals is antibacterial, very large to the side effect of ambient influnence and human body, not water-wash resistance, poor stability; In addition, inorganic antibacterial mainly uses metal ion antimicrobial technology, as Nano Silver, zinc, copper ion etc., expends the energy more, moreover be scarce resource during manufacture, gathers, process can cause pollution in various degree to environment.Therefore, be badly in need of a kind of antibacterial ability of development and act on by force, to human non-toxic's evil, and the free of contamination anti-biotic material of production process, for solving the antibacterial difficult problem of hygiene article sector.
Ramie is China's special product, and ramie is perennial root herbaceous plant, is described as " China's grass; middle national treasure ", has antibacterial by the world, ventilative, nice and cool, anticorrosion, mildew-resistant, the functions such as absorbing sweat, universally acknowledged " king of natural fabric " is important textile fabric crop, the active cavity structure feature that ramie is exclusive, its filament is long, so have superior gas permeability and conductivity of heat, water suction is many and fall apart wet fast, has cooling feeling.Ramie contains the trace elements such as pyridine of giving repeated exhortations, pyrimidine and purine simultaneously, plays inhibition, have natural bacteriostatic, anti-mite, deodorant function to Escherichia coli, staphylococcus aureus, Pseudomonas aeruginosa.Ramie has superfine hollow structure, has powerful adsorption capacity.Therefore, ramie is the desirable anti-biotic material as the amenities such as sanitary napkin, paper diaper inner core.At present, market yet there are no the report of amenities utilizing ramee to manufacture sanitary napkin, paper diaper etc., need in people's life a kind of with ramie be raw-material, have antibiotic property and gas permeability, loose moist by force, personal hygiene article that anticorrosive mildewproof is effective.
Summary of the invention
The object of this invention is to provide a kind of preparation method of antibacterial ramie fiber, and the application on paper diaper, sanitary napkin.Using the inner core material of antibacterial ramie fiber of the present invention as the amenities such as paper diaper, sanitary napkin, its antibiotic property, gas permeability, loose by force moist, be a kind of anticorrosion, anti-biotic material that anti-mold effect is splendid.
Above-mentioned purpose of the present invention will be further described by following detailed description and embody.
