Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a sanitary napkin/pad, in particular to a far infrared anion complex sanitary napkin/pad. 
       BACKGROUND OF THE INVENTION 
       [0002]    According to investigation, a majority of women suffer from various degree of the gynecological inflammation. The genital itch is caused by easy infection of candida albicans, which is due to the hormonal change during menstruation that causes the decrease of the acidity in the vagina, on top of the impermeability of the sanitary napkin, and the poor air circulation in the vaginal area turning the vagina into a culture medium for bacteria. This symptom is worse during the sultry and humid weather. The menstruation also sends out unpleasant smell that greatly affects female&#39;s daily life and work. Therefore, the functions about anti-inflammation and deodorization for the sanitary napkin are gaining more and more public&#39;s attention. At present, regarding the solution for anti-inflammation and deodorization effects on the sanitary napkin, the most common practice is to add anti-inflammation medicine directly onto the sanitary napkin. However, when using this kind of sanitary napkin, the medicine directly affects the surrounding area of the vagina which may cause allergic reaction, some side effects or discomfort to the contacted area. The menstruation may also reduce the efficacy of the medicine. As a result, this kind of sanitary napkin is not suitable for using widely. 
       SUMMARY OF THE INVENTION 
       [0003]    Accordingly, it is an object of the present invention is to provide a far infrared anion complex sanitary napkin/pad with good effects of sterilization, anti-inflammation, and deodorization without irritation. 
         [0004]    To achieve the above object, the present invention is carried out by the following technical solution: 
         [0005]    A far infrared anion complex sanitary napkin/pad having multi-layer structure comprises, in sequence from upper to lower layer, a web layer, an absorbent layer, a waterproof coating layer and an adhesive layer, which are stuck firmly together. The sanitary napkin/pad further comprises a floral essential layer and a far infrared anion fiber layer attached together firmly. The floral essential layer is paper/fabric layer soaked with extracted floral essential solution; the far infrared anion fiber layer is woven of fiber obtained from a mixture of 8-10 wt % of anion mother grain, 8-10 wt % of far infrared mother grain, and homopolymer carrier or spinning liquid. The anion mother grain is made from nano grade mineral powder that activates anion in the air. The far infrared mother grain is made from nano grade mineral powder that activates far infrared. 
         [0006]    Preferably, the nano grade mineral powder is nano grade tourmaline micro-powder that activates anions in the air. The nano grade mineral powder is nano grade far infrared ceramic micro-powder which activates far infrared. The far infrared anion fiber layer automatically releases anions and far infrared. Comparing the far infrared anion fiber with the conventional surface coating method, the far infrared produced by this kind of fiber has better durability. When the far infrared mother grain becomes humid upon contacting with human body, it releases the far infrared that penetrates the subcutaneous tissue of human body. The far infrared enhances human body&#39;s micro-circulatory system, the metabolism and the immunity. Anions also have good disinfecting effect. Negative oxygen ions have higher activity that can destruct the cell membrane of the bacterium or the activity of the protoplasm enzyme. Moreover, once the anions bond with the bacteria, the bacterial structure is changed, or the energy is converted which leads to bacteria death and disables the ability to produce new bacteria. Thus, it serves the purposes of disinfection and sterilization. Anion powder can ionize the air, and it also has the thermoelectric and piezoelectric characteristics. Therefore, under minor changes of temperature and pressure, it creates the voltage difference between anion crystals. The static voltage could be up to one million volts which will create an electric field. The high voltage ionizes the air in the electric field, and the electrons that are hit will stick to nearby water and oxygen molecules, which transform to air anions, which are negative hydrogen ion and negative oxygen ion. Both negative ions have the features of disinfection, sterilization, and prevention of many gynecological diseases. Anion lining has the advantages of softness, water resistance, and obvious effect of anion. Especially with added infrared emission material, the far infrared anion fibers can produce anion and infrared that will improve the blood circulation, aid in sleep, and enhance the health benefits of the product. Therefore, utilizing this technology on the sanitary napkin/pad will help to improve the micro-circulation around the vagina, to increase the amount of biological enzyme, to increase the acidic secretion in the vagina, and to adjust the PH value. All these effects are beneficial to female&#39;s health. 
         [0007]    Preferably, the floral essential solution is made from a floral mixture of 3-8 parts by weight of lily, 8-14 parts by weight of honeysuckle flower, 3-8 parts by weight of chrysanthemumflower, 4-9 parts by weight of tree peony, 3-8 parts by weight of Chinese rose, 2-6 parts by weight of clove, 3-8 parts by weight of orange blossom, 1-6 parts by weight of common coltsfoot flower, 3-8 parts by weight of lotus, 8-16 parts by weight of jasmine flower, 5-10 parts by weight of rose, 6-10 parts by weight of common peony, 3-8 parts by weight of silktree albizzia flower, 3-6 parts by weight of wintersweet flower, 5-12 parts by weight of peppermint, 4-10 parts by weight of licorice, 3-8 parts by weight of mugwort leaf, 4-8 parts by weight of drug sweetflag rhizome, 3-12 parts by weight of lavender and 2-10 parts by weight of lemongrass. The floral mixture goes through extraction to obtain a blended essential oil; then the blended essential oil is diluted to 1000˜1200 times to obtain the floral essential solution. The floral essential solution has the features of antibacterial, sterilization, and skin benefits. The floral essential solution also has the ability to increase the amount of oxygen that the anion material can carry, which is prominently beneficial to female&#39;s health. 
         [0008]    The far infrared anion complex sanitary napkin/pad also includes a Chinese herbal essential layer. The Chinese herbal essential layer is paper/fabric layer soaked with Chinese herbal essential solution. 
         [0009]    Preferably, the Chinese herbal essential solution is made from a mixture of Chinese herbs—containing 5-12 parts by weight of dried rehmannia root, 8-16 parts by weight of radix scrophulariae, 4-8 parts by weight of angelica, 8-16 parts by weight of honeysuckle flower, 5-12 parts by weight of forsythia fruit, 5-12 parts by weight of baicalin, 4-8 parts by weight of red paeony root, 5-12 parts by weight of tree paeony bark, 5-12 parts by weight of poria skin, 1-5 parts by weight of licorice, 6-15 parts by weight of Radix sophorae flavescentis, 12-18 parts by weight of common cnidium fruit, 12-18 parts by weight of belvedere fruit, 12-18 parts by weight of densefruit pittany root-bark, 4-8 parts by weight of pricklyash peel, 1-4 parts by weight of halite. The mixture of Chinese herbs is then cooked, filtered, and purified to obtain the Chinese herbal essential solution. The Chinese herbal essential solution has remarkable beneficial effects on female&#39;s outer genital itch, abnormal leucorrhea, and vaginitis. 
         [0010]    Preferably, nano-silver and bamboo vinegar or bamboo charcoal are added into the absorbent layer. The addition includes 0.01-5 parts by weight of nano-silver having diameter less than 20 nm, 0.1-10 parts by weight of bamboo vinegar or 0.1-10 parts by weight of bamboo charcoal. The amount of the nano-silver on the absorbent layer is 1˜400 μg/cm 2 . The nano-silver has the characteristics of durable effects, wide spectrum, strong antibacterial effect, better stabilization, better effect upon interacting with water, non-toxic, and no pollution to the environment. The more important is that it has the ability to release far infrared, which would work with the far infrared anion fiber layer in the sanitary napkin/pad to improve the effect of sterilization, anti-inflammation and deodorization. The ethanol material in the bamboo vinegar has the features of skin cleansing and sterilization. Therefore, the bamboo vinegar has the benefits of sterilization, itch relief, and deodorization. The acetic acid, ethyl ether, and alcohol in the bamboo charcoal have the benefits of deodorization, disinfection, and moisture absorption. 
         [0011]    Preferably, the paper/fabric layer is a tissue layer, a non-woven fabric layer or a puffy cotton layer. 
         [0012]    Preferably, the adhesive layer is stripe interrupted adhesive layer, which improves airflow. 
         [0013]    Preferably, the floral essential layer is above the Chinese herbal essential layer, which can avoid the stimulation of the Chinese herbal essential layer to the skin of human body. 
         [0014]    Preferably, the floral essential layer is tightly attached to the far infrared anion fiber layer, and the essential liquid in cooperating with the anion materials improves the oxygen content. 
         [0015]    Preferably, the floral essential layer is above the far infrared anion fiber layer, the floral smell is emitted by the floral essential layer, and the floral essential layer with health effect is suitable to touch with the skin. 
         [0016]    Preferably, the Chinese herbal essential layer is located at the central portion of the sanitary napkin/pad, and the ratio of the length and the width of the Chinese herbal essential layer with respect to the length and the width of the sanitary napkin/pad is in a range of ½ to ⅔, and thus the materials are concentrated and saved. 
         [0017]    The far infrared anion complex sanitary napkin may be provided with two wings on the two side edges, and the far infrared anion complex sanitary pad may be also provided with or without two wings on the two side edges. 
         [0018]    The nano grade means that the diameter is not more than one billionth of a meter. 
         [0019]    The advantages of present invention are: (1) the floral essential solution not only has the features of sterilization, anti-inflammation, and skin benefits, but also blocks the medicine in the lower layer to directly irritate the contacted skin; (2) the floral essential layer sticking firmly with the far infrared anion fiber layer has the ability to increase the amount of oxygen that anion material can carry, which is beneficial to female&#39;s health; (3) the Chinese herbal essential solution has a remarkable beneficial effect on female&#39;s outer genital itch, abnormal leucorrhea, and vaginitis; (4) the far infrared mother grain in the far infrared anion fiber layer facilitates the micro-circulation around the vagina, increases the amount of biological enzyme and the acidic secretion in the vagina, adjusts the PH value, and increases the immunity of female&#39;s body.
