Description

Silver Sanitary Pad Manufacturing Method}

The present invention relates to a method for manufacturing a silver-added sanitary napkin, and more particularly, to manufacturing a clean silver sanitary napkin using the sterilizing power of silver.

A conventional method for coating silver nanoparticles on the surface of a fiber and a sanitary napkin product manufactured therefrom, and relates to a method for coating silver nanoparticles in a uniform size and dense form on the surface of a fiber in a simple method without using a reducing agent or expensive equipment It is known to relate to a method and a sanitary napkin manufactured to have effects such as antibacterial, sterilizing, and deodorizing using the same.

In addition, the fiber surface coated with silver nanoparticles can be used as an antibacterial material, so the application range is wide. In order to coat the silver nanoparticles on the surface, a deposition method, an electrochemical method, a method using a reducing agent, a coating method by adsorption, etc. have been generally used.

Gas Deposition is a method of vaporizing metal and coating it on the surface. Recently, spherical nanoparticles are arranged in a hexagonal shape, silver is deposited, and then a certain nanoparticle pattern is formed by removing the nanoparticles again. The forming technique has been reported.

Electrochemical Deposition is a method in which metal ions are adsorbed to the surface to be treated and then reduced by applying an electric charge. A method of electrochemically forming a silver film on the surface of gold, silver peroxide, lithium peroxide, and acetonitrile on the surface of silicon. A method of electrochemically forming silver nanoparticles with a thickness of 2 to 20 nm using a nitrile solution and a method of coating silver nanoparticles using a silver nitrate/acetone/water solution on cellulose acetate fibers have been known.

As a method using a reducing agent (chemical reduction method), n-propyltrimethoxysilane is patterned on a glass surface, a reducing agent is adsorbed thereon again, and silver or gold salt is added thereto to obtain a surface coated with silver or gold particles; and a method of forming silver nanoparticles by adsorbing a silver salt on the surface of a polyimide and connecting it at a high temperature of 250°C, etc. have been known.

In general, the coating method is a method in which the surface is treated with a thiol group or an amine group, and then silver nanoparticles or gold nanoparticles are adsorbed thereto to attach to the surface, or the nanoparticles are attached to the surface using electrostatic force, and dimethylformamide is used. A method of generating silver particles in a solution using a reducing agent and then introducing them to a glass surface using electrostatic adsorption again, a method of coating gold nanoparticles on silica nanoparticles whose surface has been modified with an amine group or a thiol group, and poly After treating the solid surface with 4-vinylpyridine, there has been known a method of adsorbing silver nanoparticles again and re-coating the particles with tungsten oxide (WO3).

However, in the case of the deposition method and the electrochemical method, it is not economical because expensive equipment is required for the production of silver nanoparticles. In the case of the method using a reducing agent, it is inconvenient to process the reducing agent at a very high temperature, and in the case of the coating method There was a problem that the nanoparticles had to be separately prepared and processed.

Accordingly, there is an increasing need to develop a method capable of coating silver nanoparticles in a uniform size on the surface of a specific fiber by a simpler and more economical method.

In addition, in order to use silver in various fields capable of controlling microorganisms, it is important to manufacture silver nanoparticles at low cost, to elucidate the mechanism of the antibacterial effect, and to improve the antibacterial effect.

On the other hand, the conventional disposable sanitary napkins have been overlooked for bacterial growth, bacterial growth, and odor generation due to the decay of secretions because they focus on the leakage of secretions. Therefore, it causes a lot of inconvenience due to the occurrence of dermatitis or odors due to menstruation. have been through

As a result of examining the ingredients of commercially available disposable sanitary napkins and diapers, they are composed of nonwoven fabric and polyethylene film. 99% of the film material is chemical fibers and plastics such as polypropylene or polyethylene, and the absorbent material is a polymer called a polymer absorber, which has a water absorption rate of 1000 times and absorbs the liquid by changing it into a jelly state. on material display

It is easily misunderstood as 'absorbent paper, cotton pulp'.

In addition, conventional disposable sanitary napkins and diapers use fluorescent bleach (fluorescent brightener) to prevent yellowing in the process of processing wood into pulp during the manufacturing process, which is carcinogenic. Even a small amount of these substances can affect the next generation. In addition to this, it varies depending on the skin and constitution of each person, but on average, after 2-3 days after wearing, itching and soreness occur, and there are problems such as a bad smell.

An object of the conventional sanitary napkin is to provide a method of manufacturing a silver sanitary napkin to solve the problems that cause rash, deodorization, and cold sores because the skin-contacting surface of the sanitary napkin is almost non-woven and has positive ions.

Another object of the present invention is to provide a method for manufacturing a silver sanitary napkin which is inexpensive and the manufacturing process of the silver-containing fiber is simple.
