Description

Feminine hygiene products and preparation method thereof

The present invention relates to an absorbent pad and a method of preparing the same, and more particularly to an externally applied sanitary napkin and sanitary pad and a method of preparing the same. Background technique

Sanitary napkins and sanitary pads are similar in structure and consist of a liquid permeable surface layer, a liquid absorbing layer and a liquid impervious adhesive layer.

Sanitary napkins are used during women's travel. When women have menstrual cramps, their body resistance is poor, and they are prone to infection. In particular, the natural defense effect of inhibiting bacterial growth is weakened by the slight opening of the cervix, the endometrial exfoliation, and the reduction of vaginal acidity. Invasion of pathogenic bacteria can easily cause inflammation or infection of the genitourinary system. In addition, some women cannot replace sanitary napkins in time due to various reasons. The localized menstrual blood has greatly improved the humidity and poor ventilation and ventilation, which is more beneficial to the reproduction of bacteria and enhances the frequency of various gynecological diseases.

In addition, many women use sanitary pads when there is less menstrual blood or more secretions. Because the sanitary pad structure is similar to sanitary napkins, there are also disadvantages that are beneficial to bacterial reproduction and may lead to various gynecological diseases.

Among the women's hygiene products currently on the market, some are applied to the surface of sanitary products with a variety of Chinese herbal medicines or a variety of Chinese herbal medicine particles are packaged in the internal structure of sanitary products, which can sterilize, inhibit bacteria, alleviate and analgesic. It removes inflammation and spreads fragrance, thus achieving the purpose of preventing various gynecological diseases and removing menstrual blood odor. However, most of these products include multiple drugs and are costly. At the same time, these products are discarded after being used once. There is no mature technology for recycling, and they are still treated by landfill. Therefore, if the drugs can reduce the types and quantities, it is obviously meaningful for environmental protection. Summary of the invention

It is an object of the present invention to provide a feminine hygiene product which is sterilizable, anti-inflammatory and which can reduce environmental pollution and a preparation method thereof.

According to the present invention, a feminine hygiene product is provided, which comprises a liquid permeable surface layer and is transparent a liquid absorbing layer below the liquid surface layer and a liquid-impermeable adhesive layer under the liquid absorbing layer, characterized in that the outer surface of the liquid permeable surface layer comprises borneol

On the contrary, when the amount of the borneol applied in the sanitary napkin or the sanitary pad is greater than the respective maximum amounts specified in the foregoing invention, although the object of the present invention can be attained, the effects of sterilization, bacteriostatic, anti-inflammatory, etc. are increased. Micro, so this will cause waste of borneol drugs, while also adding some pressure to environmental protection, it is not desirable. The method of preparing the feminine hygiene product of the present invention is described in detail below.

First, a polymer material having a water absorbing property, such as a polymer composite paper or a dust-free paper, is formed into a liquid absorbing layer having a desired shape, for example, a strip shape. The liquid absorbing layer has a strong adsorption property and can absorb body fluids or other excretions.

Subsequently, an adhesive is applied to one side of the liquid absorbing layer or one side of a liquid permeable surface layer, and the liquid absorbing layer and the liquid permeable surface layer are bonded to bond the two together. The liquid permeable surface layer is preferably made of a material that has unidirectional penetration and is not capable of reverse osmosis. Thus, after the body fluid is absorbed by the liquid absorbing layer prepared as described above, the body fluid does not re-infiltrate to the outer surface of the liquid permeable surface layer, so that the outer surface of the liquid permeable surface layer which is in contact with the human body can be kept dry.

At this time, it is possible to apply a liquid medicine composed of borneol and a pharmaceutically acceptable solvent (e.g., alcohol) to the outer surface of the liquid permeable surface layer. If alcohol is used, its concentration can be

70% - 75%. Moreover, as the concentration of alcohol increases, the bactericidal effect will be better and better, and when the alcohol concentration is 75 %, the effect is best. The concentration of the liquid medicine composed of borneol and alcohol may also vary within a certain range, as long as the amount of borneol contained in the sanitary article applied from the outer surface of the liquid permeable surface layer of the sanitary article can reach the present invention. The purpose of sterilization, anti-inflammatory, and the amount of the liquid is relatively easy to dry the sanitary article. For example, the concentration of the liquid medicine may be from about 4:100 g/ml to about 6:100 g/ml, and the amount of the liquid medicine applied to each sanitary article at this time can satisfy the above requirements, and can be ensured to be applied to sanitary articles. The amount of borneol on the outer surface of the liquid permeable surface layer. Preferably, the concentration of the drug solution is in the range of about 4. 5: 100 g/ml to about 5. 5: 100 g/ml. More preferably, the concentration of the drug solution is about 5: 100 g/ml. "Administration" herein includes all possible methods for uniformly applying the mixed solution to the sanitary article from the outer surface of the liquid permeable topsheet of the sanitary article, for example, spraying, brushing, and the like.

After the liquid medicine composed of borneol and alcohol is applied to the outer surface of the liquid permeable surface layer, the liquid medicine is substantially infiltrated, and the sanitary product can be optionally dried. Finally, an adhesive is applied to the other side of the liquid absorbing layer or to one side of the liquid-impermeable adhesive layer, and the liquid-impermeable adhesive layer is adhered to the other side of the liquid absorbing layer. Thus, the sanitary article of the present invention is obtained.
