Description

A kind of far-infrared negative-ion breathable sanitary towel and preparation method thereof
Technical field
The present invention relates to hygiene article sector, particularly relate to a kind of far-infrared negative-ion breathable sanitary towel.
Background technology
The female body situation in menstrual period is poor, resistance is also more weak, be vulnerable to the infection of antibacterial, cause uncomfortable, along with the raising of people's living standard, the demand pursuing healthy, comfortable life style is increasingly ardent, and various functional health-oriented products are more and more subject to the favor of people, and the personal health nursing materialss such as sanitary towel are also towards health care future development.Sanitary towel, also known as cotton wool, be the absorptive material of a kind of tool, the high molecular polymer that main material is formed for cotton, adhesive-bonded fabric, paper pulp or more material complex and high molecular polymer extrusion coating paper, be used for absorbing feminine menstrual and carry out the time of tide, from the menses that vagina flows out.
Have statistics to show, the current women worldwide size of population about 3,500,000,000 people, nearly 2,000,000,000 women need to use sanitary towel.From single women, a women will experience 60 days menstrual phases for 1 year, within 1 year, approximately need 480 sanitary towels, calculate according to a slice sanitary towel weight 10 grams, thus 2,000,000,000 women will produce the rubbish of about 9,600,000 tons for 1 year, the volume ratio of occupying due to these " white garbages " is larger, carry out landfill disposal according to existing processing method to need to consume a large amount of landfill yards, occur seizing good farmland, arable land with the mankind, corrode the serious problems of human habitat, thus, produce and use degradable napkin, change material therefor in existing product, after making it to abandon and being buried in underground, degraded can be produced through the regular hour, return the living environment of mankind's green, very necessary.
According to the theory that geodesy and air joint committee of geographic physical League of Nations adopt, the molecular formula of negative aeroion is O 2-(H 2o) n, or OH-(H 2o) n, or CO 4-(H 2o) n.Here the said negative aeroion with environment-friendly function mainly refers to first two micromolecule anion.Briefly refer to electronegative oxonium ion, colorless and odorless.Air is by countless molecule, former molecular.After the molecule in air or atom lose or obtain electronics, just form charged particle, be called ion; Positively charged is cation, and electronegative is anion.Anion is a kind of electronegative gas ion in air, free electron that air molecule produces major part obtain by oxygen, thus, usually negative aeroion is referred to as " negative oxygen ion ".
Existing sanitary towel, generally comprise transparent liquid surface layer, absorbent cores, liquid-tight bottom that lamination is successively arranged, absorbent cores is mixed by bulky nonwoven cloth and water-absorbing resins usually, sanitary towel's entirety does not produce the function of anion, also do not possess sterilizing function simultaneously, in addition, traditional sanitary towel contact site damp after imbibition is strong, and user very easily produces discomfort.
