Description

Antibacterial non-woven and antiseptic preparation method
[technical field]
The present invention relates to the manufacture method of a kind of antibacterial non-woven and antiseptic.
[background technology]
At present, antibacterial non-woven is various in style, many products its antibacterial effect that covets, and ignored its harmfulness to human body and environment.
Publication number is that wherein divalent zinc ion comes from zinc sulphate hydrate, zinc acetate, zinc chloride, zinc nitrate in the Chinese patent application " preparation method of shitosan/zinc compound bactericide " of CN100360035C; Use spirit of vinegar dissolving shitosan.Wherein, zinc nitrate is corrosive.At high temperature decomposing to produce to have stimulates and hypertoxic oxides of nitrogen gas, sucks to cause poisoning.Zinc chloride toxicity is very strong, can severe irritation and burn skin and mucous membrane.Zinc acetate has harm to environment, and rabbit skin irritation test slightly stimulates.Zinc sulfate has spread effect to stomach, and environment is had harm.Acetic acid belongs to the lower toxicity material, and penetrating odor is arranged, and is very big to skin irritation.Acetic acid acidity is bigger, and behind the dissolving shitosan, the pH value of solution value is lower than 4.5, and mixed solution needs could use behind the adjust pH.In sum, zinc chloride, zinc nitrate toxicity are bigger, and zinc sulfate, zinc acetate all have harm to environment, if use the antiseptic of above-mentioned zinc salt for main antimicrobial component, can spread effect be arranged to human body, and environment is had certain harm.
In the preparation method of above-mentioned shitosan/zinc compound bactericide, make the chitosan-zn complex solution after, still can't use.The acetone and the ethanol that need further to add capacity obtain white precipitate, and with the ethanol washing, grind into powder is used dissolving with hydrochloric acid, the NaOH adjust pH, and just can use after the high-temperature sterilization.This process cost height, complex process, practicality is relatively poor.
Chitin is a kind of natural polysaccharide that extracts from the crust of shellfishs such as shrimp, crab, also is that nature is only second to cellulosic second largest living resources.Shitosan is the deacetylated derivative of chitin; have excellent biological compatibility, biodegradability, Nantural non-toxic and multiple biologically active; especially broad spectrum antibacterial; and owing on its strand a lot of amino, hydroxyl isoreactivity group are arranged; have very high reactivity, and be easy to transition metal ions generation complex reaction.In recent years, shitosan has been subjected to people's extensive concern as a kind of natural antibacterial agent.But the antibacterial activity of comparing shitosan with traditional antiseptic is lower, and is by the antibacterial activity of methods such as modification, blend raising shitosan, most important as the application of antiseptic for shitosan.Though by can improve the antibacterial activity of shitosan to a certain extent to the derivatization treatment of shitosan, but effect is also not obvious, still can't satisfy its application demand, and the derivatization process complexity of shitosan, severe reaction conditions is unfavorable for large-scale production.Metal ion has stronger antibacterial activity as traditional antiseptic, but its bio-toxicity can not satisfy the requirement of the green non-poisonous product of current development.Now, the most frequently used metal ion comprises silver ion, zinc ion and copper ion.The silver ion antimicrobial agent cost is higher, and the potential risk of oxidation blackening is arranged." ecological textile specification requirement " GB/T18885-2002 and " the general and special technical requirement of ecological textile " Oeko-Tex100-2002 have strictness to limit the quantity of to copper ion.
[summary of the invention]
