Description
Technical field
This utility model relates to field of hygiene products, particularly relates to the hygienic articles with antibacterial functions, relates more particularly to sanitary towel or the diaper with antibacterial functions.
Background technology
Antibacterial include antibacterial, sterilizing, sterilization, mildew-resistant, anticorrosion.The process using chemically or physically method to kill antibacterial or prevention bacterial growth breeding is antibacterial general name.Antibacterial is within a certain period of time, to make the growth of certain micro-organisms (antibacterial, fungus, yeast, algae and virus etc.) or breeding be maintained at necessary chemical substance below horizontal.
Antibacterial is broadly divided into organic antibacterial agent, inorganic antiseptic and natural antibacterial agent.Organic antibacterial agent anti-microbial property is high, sterilization speed is fast, but to environment and human body are harmful and working life is short, poor heat resistance；Natural antibacterial agent antimicrobial efficiency is high, safety non-toxic, but processing difficulties, poor heat resistance.Inorganic antiseptic becomes, because of features such as its effective antibacterial phase length, good, the has a broad antifungal spectrum of heat resistance, the class antibacterial being most widely used.
In inorganic antiseptic, the inorganic salt of metal ion or the inorganic antiseptic kind of complex are most, purposes is the widest, yield is most, wherein antibiotic property size is ordered as: Hg > Ag > Cd > Cu > Zn > Fe > Ni etc., but it is inadequate for only having antibiotic property, also requires that human body will not be damaged by it, the metals such as Hg, Cd, Pb also have antibacterial ability, but harmful.The safety of metal ion is ordered as: Ag > Co > Ni > Al > Zn > Cu=Fe > Mn > Sn > Ba > Mg > Ca, so the result that safety and antibiotic property are considered jointly, best with Ag ion, next to that Cu system and Zn system, therefore the these three inorganic antiseptic with inorganic compound as carrier obtains a wide range of applications.Cu ion, because itself is with color, can affect the representability of product, and silver is because of problems such as its easy oxidation discoloration, expensive, easy reunions, and range is all restricted.
Metallic zinc is due to itself antibacterial ability is argent 1/1000, cause most of research institution and manufacturer all energy to be concentrated in the modified research and development of Ag and nanometer silver and improve its performance as antibacterial, thus have ignored the zinc plurality of advantages as antibacterial, to its research seldom.Actually, Nano-Zinc antibacterial can overcome nano silver antimicrobials many defects in actual applications, such as easily oxidation, blackening, expensive, it is difficult to dispersion etc., and possess significant antibacterial effect, substantially prolongs antibacterial ageing, especially can relatively easily be scattered in corresponding goods, in plastics, textile fabric, slurry, waterborne liquid, oil soluble liquid, have greatly expanded range of application.Therefore, research and development Nano-Zinc antibacterial can greatly meet social desirability.
The anti-biotic material that in the past hygienic articles such as sanitary towel, diaper was added is belonging to organic anti-bacterial material or natural antibacterial material mostly, instant sterilization, sterilizing effect fine, but do not have ageing, i.e. using effect is gradually lowered with the passing of time.Therefore, when product comes into the market to arrive in user's hands, its antibacterial effect is decayed totally the most substantially.This is also to consume authoritative institution why to tend not to reach the reason of manufacturer's Expected Results for the Bacteria Detection result of market product.And " health " problem in hygienic articles is essentially from two aspects.One is product raw material and auxiliary material itself does not reaches hygienic requirements, product manufacturing, pack, transport, store, in sales process, the chance of germ contamination can be found everywhere.Two is hygienic articles secondary pollution in use, such as people on hand with a large amount of antibacterials, can bring pollution during opening hygienic articles, and product use during the pollutant that produce also can become the prolific hotbed of microorganism.And use the hygienic articles including Nano-Zinc antibiotic complex, it is ensured that use whole process all to keep bactericidal properties from producing to, be truly realized safety and sanitation.
