As a deodorant component, the cypress extract and green tea extract, which are adsorbed on the carrier, react with the malodorous substance and cause a change in molecular structure, thereby remarkably reducing the odor generated in the human body or living odor.

Hereinafter, the present invention will be described in more detail with reference to Examples. These examples are only for illustrating the present invention, and the scope of the present invention is not to be construed as being limited by these examples.

Example 1 Preparation of Nanosize Carriers

One or two or more mixtures selected from the group consisting of zeolite, carboxymethyl cellulose (CMC) and bentonite and silica were prepared by conventional sol-gel preparation and grinding to prepare nano-sized carriers. .

Specifically describing the preparation of nano-sized carriers by the sol-gel method, sol refers to the dispersion of colloidal particles of 1 μm or less, and is obtained from a metal alkoxide solution or a hydrous / anhydrous metal oxide by chemical reaction. It is possible to manufacture using colloidal particles of / anhydrous metal oxide, and it is called sol-gel process because the viscosity of sol is gradually increased to form gel during the process. Here, the gel refers to a three-dimentional polymeric network that forms a metal-oxide-metal (M-O-M) bond similar to that found in oxide ceramics.

More specifically, the sol-gel process can be classified into a colloidal sol-gel using colloidal particles and a polymer sol-gel using an organometallic precursor such as metal alkoxide, depending on the raw material. More general. Alkoxide molecules exist as monomers, dimers, etc. under the influence of the individual alkoxides, solvents or other factors used, and polymerization occurs due to hydrolysis and polycondensation reactions of the metal alkoxides. Water that is added externally during the polymerization acts as an initiator and acids or bases catalyze these reactions. The initial viscosity of the sol is rather low and in most cases comparable to that of water. However, if the polycondensation occurs at a significant size, the sol turns into a gel. When these reactions begin to occur, the metal alkoxide solution begins to turn into a sol. The relatively low molecular weight species present during the initial gelling step are called oligomers.

Example 2: Preparation of Filter Cloth with Nano-size Carrier Adhered to Resin

The carrier prepared in Example 1 was added during fabrication of cotton fiber, synthetic fiber, and fiber, pulp, or sponge using fine breathable microfiber, and then fabricated to prepare an adsorbent fabric having the carrier fixed thereto. In another method, the carrier is applied to a resin product made of cotton fiber, synthetic fiber, a fiber made from a fine fiber with good air permeability, pulp, or a sponge alone or in combination of two or more, and then heated to 180 ° C. for 3 minutes to swell the carrier. A fixed adsorption cloth was prepared. The amount of resin used in this example was 2 to 50 parts by weight based on 100 parts by weight of the carrier.

If necessary, the binder may be available in the range of 2 to 10 parts by weight with respect to 100 parts by weight of the carrier to be evenly bonded to the surface of the resin. The binder may be selected from among adhesives used for vinyl acetate solution, urethane binder or fiber, pulp and the like.

Example 3: Adsorption of Sterilizing and Deodorizing Components

The sterilizing and deodorizing component (3) was adsorbed into the hygroscopic pores of the swollen carrier by applying the sterilizing and deodorizing component to the filter cloth prepared in Example 2. 3 parts by weight of 10,000 ppm colloidal silver with 100 parts by weight of the nano-size carrier, 30 parts by weight of deodorizing component dissolved in ethyl alcohol (15% solution) alone or mixed with green tea extract, nosong extract or wood vinegar solution and TiO ₂ 20 Part by weight was adsorbed.

In the adsorption, the sterilization and deodorization components are administered to the low pressure tank, sufficiently mixed, and then the pH is adjusted to a nonionic or anionic state, and then a small amount of less than 3% of a surfactant is administered, followed by administration of an adsorbent at 30 to 50 ° C. After 3-6 hours, the contents were taken out and dried.

Colloidal silver adsorbed on the carrier for sterilization has the function of sterilizing 670 species of bacteria, and also has the function of activating metabolism by silver ions, which is beneficial for creating a living space for a clean and healthy life.

As a deodorant component, the cypress extract and green tea extract, which are adsorbed on the carrier, react with the malodorous substance and cause a change in molecular structure, thereby remarkably reducing the odor generated in the human body or living odor.
