Description

Antibacterial pad

1 is a vertical cross-sectional view of an antibacterial pad according to an embodiment of the present invention.

The present invention relates to an antimicrobial pad and a method for producing the antimicrobial pad. More specifically, the present invention relates to an antimicrobial pad and a method for manufacturing the same, which significantly improve hygienic performance such as antibacterial and deodorization and prevent skin diseases.

Pads which are generally used are provided with a cover having a hygroscopicity on the upper surface and a protective cover to prevent liquid from leaking on the lower surface, and has a predetermined thickness between the cover having the hygroscopicity and a protective cover where the liquid does not leak. After providing the absorbent which has, it formed by the method which fuses each said cover edge.

The pads prepared in this way are used only for absorbing and treating secretions, but are not ventilated by a protective cover to prevent leakage of liquid after wearing. There was a problem such as occurring.

Therefore, in recent years, in order to solve the above problems, the pad was manufactured by a method of making a second nonwoven fabric by applying a special mixture to the nonwoven fabric, and applying and fusion in the middle of the nonwoven fabric.

However, because the pad is provided with a vent for smooth ventilation, the secretion may leak into the vent when there is a lot of secretion. And psychological burden.

The present invention provides an antimicrobial pad that is excellent in antibacterial and deodorizing properties and can prevent skin diseases.

The present invention also provides a method for producing the antimicrobial pad.

The antimicrobial pad according to one feature of the present invention includes a first sheet, a second sheet, a third sheet, and a nanosilver resin layer. The second sheet corresponds to the first nonwoven fabric. The third sheet is disposed between the first sheet and the second sheet and comprises 70 to 80% by weight of charcoal, 5 to 20% by weight of ocher, 5-20% by weight of ceramic powder and 10 to 20% by weight of natural resin. The mixed solution is impregnated and applied to the upper and lower surfaces of the sheet. The nanosilver resin layer is formed on the first sheet and is made of natural resin and nanosilver.

Method for producing an antimicrobial pad according to an aspect of the present invention is to mix and stir 70 to 80% by weight of charcoal, 5 to 20% by weight of ocher, 5 to 20% by weight of ceramic powder and 10 to 20% by weight of natural resin Preparing, impregnating the mixed solution in a third sheet to dry, preparing a silver diluted natural resin solution having a silver concentration of 20 to 40 rpm by mixing nanosilver with a water-soluble natural resin, the natural resin solution Spraying a surface of one surface of the second sheet and applying the same; and bonding the first sheet, the second sheet, and the third sheet in order.

The antimicrobial pad is excellent in antibacterial and deodorizing performance, and can prevent skin diseases, and can be used for various purposes such as diapers and sanitary napkins.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a vertical cross-sectional view of an antibacterial pad according to an embodiment of the present invention.

Referring to FIG. 1, the antimicrobial pad includes a first sheet 300, a second sheet 100, a third sheet 200, and a nanosilver resin layer 110. In addition, the third sheet 200 is a functional sheet which is impregnated and applied by a mixed solution (described later) on which the upper and lower surfaces of the sheet are functional and dried.

The nanosilver resin layer is formed on the second sheet 100. The nano silver resin layer is a layer formed by coating a silver dilute natural resin solution is mixed with a water-soluble natural resin and nano silver prepared using nanotechnology.

As a silver compound for producing the nano-silver, yellowing silver is used, which can be obtained by a known method (interface with colloidal chemical steel and colloid P319-340, 1997). In the preparation method, first, 70 g of sodium citrate and 38 g of ferrous sulfate are dissolved in 300 mg of distilled water. Thereafter, 100 ml of silver nitrate, in which 12.5 g of silver nitrate solution was dissolved, was added to the sodium sulfate solution at a stirring speed of 1000-5000 rpm under a distilled water temperature of about 10-50 ° C. to obtain fine particles. The silver particles produced at this time have a particle size distribution of 5-10 g / cm 2, which is placed in a centrifuge and the silver solids concentration is 1-70% by weight while recovering the silver particles. Silver is obtained.

In addition, as another method for producing nano silver, electrolysis may be used. In this way, high-purity nanonized silver can be obtained, and pure silver (99.9%) is added to distilled water to generate a low current to dissolve the ultra-fine particles of silver that are discharged.

The nanosilver is contained in the concentration of 20 to 40 ppm in the silver diluted natural resin solution. When the concentration of the nanosilver is less than 20 ppm, it is difficult to exhibit the unique characteristics of the nano silver, whereas when the concentration of the nanosilver exceeds 40 ppm, the surface properties of the coating film is not good. The nano silver is preferably included in the silver diluted natural resin solution at a concentration of 20 to 30 rpm.

Various resins may be used as the water-soluble natural resin, and preferably, Cheonyun resin prepared from plants is used. In general, organic resins produced by an organic industrial method are often used, but natural resins obtained from plants or the like must be used because they may harm the human body due to chemical action occurring in the organic resins. In particular, the pad is used because it is used in a variety of applications that are in contact with the human body.

The nanosilver resin layer is applied in a spray form on the silver dilute natural resin solution on the second sheet (100). More specifically, the second sheet 100 is applied in a spray form to one surface of the moving second sheet 200 when the second sheet 100 is released from the roll. Sprayed to the second sheet 200 in the form of a mist spray to be evenly coated on the surface.

The third sheet 200 is a functional sheet, and has a coated surface 210 in which a functional mixed solution is impregnated and applied to the upper and lower surfaces of the third sheet 200.

The functional mixed solution includes 70 to 80% by weight of charcoal, 5 to 20% by weight of ocher, 5 to 20% by weight of ceramic powder and 10 to 20% by weight of natural resin.

The third sheet 200 is prepared by impregnating the nonwoven fabric having a mesh shape with the mixed solution after sufficiently infiltrating it, and then taking it out and drying the hot air in a dry oven. At this time, the hot air drying temperature is preferably 40 to 60 ° C. In addition, special care should be taken when drying so that each component and nonwoven fabric of the mixture does not cause thermal deformation.

The antimicrobial pad according to the present invention is manufactured by interposing the third sheet 100 between the first sheet 300 and the second sheet 100 and then processing and fusion of all four sides of the sheet. In this case, the second sheet 100 interposed between the sheets 100 and 300 may be smaller than the first sheet 300 and the second sheet 100 or may be positioned only at a selective position.

When the antimicrobial pad is worn, the effect of the nano silver is on the skin of the pad wearing part of the human body, and antibacterial and sterilization, as well as the charcoal and ceramic mixture inserted in the middle portion of the pad may perform a deodorizing function when the pad is worn. . In addition, it facilitates blood circulation due to far-infrared rays emitted from charcoal and ceramics and removes waste products, preventing adult diseases and maintaining healthy skin.

The antimicrobial pad according to the present invention has excellent antibacterial and deodorizing performance and has a function of preventing skin diseases.

As described above, although described with reference to the preferred embodiment of the present invention, those skilled in the art will be variously modified without departing from the spirit and scope of the invention described in the claims below. And can be changed.
