Description
Technical field
The utility model relates to a kind of film and its absorbent article, in particular to a kind of surface has pro-skin, antibacterial effect
Perforated film and its absorbent article.
Background technique
Perforated film is chiefly used in the surface layer and guide layer of sanitary absorbent article, since perforated film when in use can be by body
Liquid passes through the infundibulate aperture water conservancy diversion on surface to absorbed layer, and the surface that body fluid returns to perforated film can be effectively prevented,
So as to which for making, seepage velocity is fast, bleeds back small, dry and comfortable absorbent article.Therefore, perforated film is widely used in defending
In the sanitary absorbent articles such as raw towel, protection pad, baby paper diaper, adult diaper and medical dressing.But present hygienic absorption
Product is made of surface layer, guide layer, absorbent core layer and counterdie mostly, and multilayered structure necessarily has certain thickness, is especially inhaled
Sandwich layer is received, therefore, when in use, absorbent article and using often forming a kind of moist, sultry environment, this ring between position
Border is easy to bacteria breed so that there is general red, itch using position, the symptoms such as allergy, thus improve the pro-skin of absorbent article,
Anti-microbial property is one of current urgent problem to be solved.And existing bacteriostatic agent mostly uses chemical antibacterial agent or silver-ion antibiotic
Agent, and chemical antibacterial agent is directly contacted with skin, mucous membrane, so as to cause skin irritatin phenomenon, and silver ion has high oxygen
To change 0.798 volt of current potential (25 DEG C), chemical stability is poor, under ultraviolet light irradiation or after being heated to certain temperature, silver ion quilt
It is reduced to metallic silver, and is immediately converts into silver oxide, makes that product is graying, blackening, this not only lowers its commercial values, also weaken
Its bacteriostasis property.In addition, silver ion bacteriostatic agent price is higher, fungal resistance is weaker.
Utility model content
In order to overcome the defect of existing absorbent article, the purpose of this utility model is to provide a kind of pro-skins, antibacterial effect
Good perforated film and its absorbent article.
To achieve the above object, the solution of the utility model is:
A kind of perforated film, it is every square centimeter that there is 20~1600 funnel shaped apertures, the upper surface face of single aperture
Product is 0.03mm2~2.5mm2, the surface of the perforated film is attached with chitin.
The perforated film is single layer structure.
The perforated film is bilayer or multilayer structure.
The chitin includes chitosan and the chitosan derivatives after chitin is deacetylated.
Chitin is adhered to by way of coating or interior addition in the surface of the perforated film.
A kind of absorbent article comprising the perforated film, including transparent liquid surface layer, absorbed layer and ventilative bottom, the absorption
Layer is set between transparent liquid surface layer and ventilative bottom, and the transparent liquid surface layer of the absorbent article is made of the perforated film.
A kind of absorbent article comprising the perforated film, including transparent liquid surface layer, guide layer, absorbed layer and ventilative bottom,
The guide layer is located at the top of absorbed layer, and the guide layer and absorbed layer are set between transparent liquid surface layer and ventilative bottom, institute
The guide layer for stating absorbent article is made of the perforated film.
After adopting the above scheme, the beneficial effects of the utility model are:
The superficial layer of the perforated film of the utility model is attached with chitin, since chitin, chitosan and chitosan spread out
Biology is the shell extraction object of arthropod such as shrimp, crab in ocean, therefore, good biocompatibility, and and there is antibacterial, antibacterial
Effect.Existing chemical bacteriostatic agent is effectively prevented when with skin contact, easily causes the generation of skin irritatin phenomenon.It is using
In the perforated film and its absorbent article of the utility model, the chitin on perforated film surface can be adsorbed on bacterial cell surface
High film is formed, prevents nutriment from transporting into bacterial cell, or penetrate into bacterial cell body, is absorbed in bacterial cell
Cytoplasm with anion, and flocculation occurs upsets the normal physiological activity of bacterial cell, thus play it is antibacterial, kill
The effect of bacterium effectively prevents absorbent article and breeds bacterium, prevent so that the bacteriostasis rate of perforated film reaches 50%~99.9%
Bacterium generates the adverse reactions such as allergy, itch using position to user's, protects the health of user significantly.Meanwhile by
Perforated film is handled by coating or interior addition manner in chitin, so that chitin is attached to perforated film surface, compared to
Chitin powder is coated in absorbent article, can more play the antibacterial effect of chitin antibacterial, and chitin distribution is more
Uniformly.
