      The wallpaper is used to improve aesthetics in a building, such as a house or an office, and is essential for a modern building. The wallpaper is manufactured by adhering paper and paper with an industrial adhesive and then printing a pattern on the surface with an organic solvent such as toluene and benzene, and then coating it with PVC using a plasticizer. Wallpaper produced in this manner is reported to cause harmful diseases such as asthma, rhinitis, atopy, allergies by releasing harmful volatile organic compounds such as carcinogens, environmental hormones.

As the interest in indoor air pollution caused by interior materials increases, the interest in products for environmentally friendly interior materials such as eco-friendly wallpaper is increasing. The focus is on converting organic compounds into natural materials and providing various functions to environmentally friendly interior materials. This includes wallpaper coated with natural minerals that emit negative ions or far infrared rays, as well as wallpaper with electromagnetic shielding, deodorant and antimicrobial wallpaper, and natural fragrance wallpaper. The functionality is becoming more important in the wallpaper as much as the aesthetic beauty.

Conventional antimicrobial wallpaper has been prepared by containing a conventional organic or inorganic antimicrobial agent in the base paper or processed paper, but the effect does not appear as the amount of the antimicrobial agent, there is a problem of low sustainability when using an organic antimicrobial agent. In order to compensate for this, manufacturers manufacture the coating or impregnation treatment of inorganic antimicrobial agents on the surface or the back of the wallpaper like resin, but when applying inorganic particles to the wallpaper, the exterior design is diversified on the wallpaper having irregularities such as embossed patterns. There is a limit to this, and there is a limit to manufacturing workability and workability, such as affecting the surface characteristics and color of the wallpaper. In addition, not only wallpaper, but also when applied to beddings such as curtains and sofas, the same problem is included.

In functional interior textile products (curtains, wallpaper, beddings, etc.) containing zeolites substituted with hydrogen, zinc and silver of the present invention, deodorizing function and organic substance decomposing function, odor, which are inherent to zeolite, are removed from the simple appearance design function of conventional products. And by having a odor removing function has a very beneficial effect on human health. In addition, by coating nano zinc oxide has a UV blocking effect. Since the zeolite has a particle size of nanometer, the specific surface area is relatively increased to maximize the catalytic activity, and the zinc oxide particles are coated to maximize UV blocking function.

      Zeolites are porous minerals in which very small holes (pores) in nanometers are regularly arranged. Numerous pores are as effective at adsorbing small substances as they are not measurable. Thanks to this, zeolite is effective in removing moisture and pollutants in the house. In addition, nitrogen monoxide and nitrogen dioxide can be decomposed into oxygen and nitrogen, which is widely used to remove automobile exhaust gases and harmful gases from factories. Recently, much attention has been paid to the development of highly functional materials using zeolites having such characteristics.

       The composition of the zeolite is usually expressed by the following formula.

M _{2 / n} OxAl ₂ O ₃ ySiO ₂ zH ₂ O

      In the above formula, M is a cation of valence n, z denotes the number of molecules of crystal water, and y / x, which is the ratio of y to x, changes depending on the crystal structure, and usually has a value of about 1 to 100 degrees.

      The pore of the zeolite is 5 to 20 kPa, and the pore size of the pore is about 3 to 13 kPa. In general, zeolites have a void volume of 15 to 50%, a surface area of 200 m 2 / g or more, a mohr hardness of 2 to 5, a density of 2 to 3 g / cm 3, and hardness and density. It has low characteristics.

The cation bound to the zeolite can be replaced with another cation such as silver (Ag) to synthesize a zeolite having additional various functions. Is a cation, such as (Ag), zinc (Zn ^{+ 2)} it is said to have been known an antimicrobial. In addition, the aforementioned metal ions can be ion exchanged in the cation site of the zeolite, and are particularly excellent in durability in comparison with the direct use of metal ions. Zeolites substituted with hydrogen ions are known to withstand high temperatures and to be durable.

      The present invention provides a fiber coating composition having an antibacterial and deodorizing function and functional fibers using the same using the characteristics of the zeolite as described above. The fiber coating composition of the present invention is characterized by comprising a zeolite substituted with silver (Ag) zinc (Zn) hydrogen (H) ions (hereinafter referred to as 'AgZnH-zeolite').

      The composition for the fiber coating of the present invention is 0.2 to 2 parts by weight of the AgZnH-zeolite particles, 1 to 10 parts by weight of the aqueous acrylic binder, 60 to 90 parts by weight of the diluent, based on 100 parts by weight of the total fiber coating composition. And 5 to 5 parts by weight and 2 to 5 parts by weight of other additives.

      AgZnH-zeolite particles included in the fiber coating composition of the present invention have an average particle diameter of 100 to 1000 nm, more preferably 300 to 700 nm, in the slurry solution. When the particle diameter exceeds 1000nm, dispersion stability problems due to precipitation in the coating composition may occur. In addition, the coarse particles exceeding 1000nm has a problem that affects the light transmittance or whiteness of the composition affects the surface properties or color of the fiber to be applied. On the other hand, when the particle diameter is 100 nm, there is a problem in that aggregation between particles occurs and a uniform coating composition cannot be obtained, which is not preferable.

      The AgZnH-zeolite having the particle size range may be prepared by pulverizing a zeolite having a large particle size or by directly synthesizing a zeolite having an average particle diameter in the above range to a nano size. The synthesis can be accomplished by heating to a high temperature in a basic solution or through hydrothermal synthesis.

      The following is a detailed description of the synthesis of AgZnH-zeolite included in the fiber coating composition of the present invention.

There are various kinds of zeolite according to the composition and structure, and as long as it has a material having internal pores, there is no need to limit the composition and structure, it can be used synthesized or pulverized to have the above particle size range. Zeolites vary according to the Al ₂ O ₃ / SiO ₂ content ratio and structure, and in particular, it is more preferable to use those selected from X type, Y type, 4A type or ZSM-5 type.

      A zeolite can use what was synthesize | combined by the well-known hydrothermal synthesis method or the sol-gel method. Alternatively, commercially available zeolites can be obtained and used. The synthesized zeolite or commercially available zeolite can be used by grinding within the particle size range of the present invention. In the case of pulverizing the zeolite, it is preferable to prepare to have a particle size in the above range, but to have a narrow and uniform particle distribution in terms of obtaining a uniform composition and applying a uniform film to the fiber surface. Zeolite grinding can be accomplished by mixing with a medium such as water to finely grind by milling, Hi-mixing or fluid collision and then classifying these fine dispersions.

      In the present invention, the zeolite grinding method can be used both milling method, high mixing or fluid collision method. Zeolite is added together with beads, followed by high-speed stirring in a bead mill, dynomill, ball mill, and attrition mill. The high mixing method is a method of causing a collision and friction to the stator by rotating the fluid at high speed with the rotor (Rotor). In addition, there is an opposite collision method as a fluid collision method.

      Next, when the zeolite is prepared according to the above method, the zeolite substituted with hydrogen, zinc and silver is synthesized by ion-exchanging the zeolite in the following manner.

1) Hydrogen (H) ion exchange

The AgZn-zeolite is added to a solution of ammonium chloride (NH ₄ Cl). After stirring for 1 to 2 hours, sodium (Na) and chlorine (Cl) ions are washed with distilled water, filtered using a subscription filter to obtain a powder. The powder obtained above is dried at high temperature and calcined for about 1 hour using an electric furnace to prepare AgZnH-zeolite.

2) Zinc (Zn) ion exchange

      The zeolite substituted with silver (Ag) is well dispersed in an aqueous solution of silver chloride (AgCl) and stirred sufficiently. The stirring time is sufficiently made for 10 to 24 hours. Next, the zeolite substituted with silver is filtered with a filter paper, sufficiently washed with distilled water, and then dried at high temperature in an oven to prepare AgZn-zeolite. The drying is preferably carried out at temperature conditions similar to those of the silver (Ag) ion exchange.

3) Silver (Ag) ion exchange

First, silver nitrate (AgNO ₃ ) containing a certain amount of silver (Ag) that can be ion exchanged The synthesized zeolite is added to the solution and stirred. The stirring time is sufficiently made for 10 to 2 hours. Next, the ion-exchanged powder is washed with distilled water and the powder is recovered by using the filter. Finally, the recovered powder is dried at high temperature to prepare Ag-zeolite. Preferably, the drying is performed using a heating mechanism such as an oven. It is preferable that the said drying temperature is 100 degreeC-120 degreeC.

      The cation substitution of the zeolite may be performed in the order of 1) hydrogen cation substitution, 2) zinc cation substitution, and 3) cation substitution. However, in the substitution order, the order of 1), 2) and 3) is not an absolute substitution order necessary for achieving the effect of the present invention. Therefore, those skilled in the art to which the present invention pertains can produce the AgZnH-zeolites regardless of the substitution order within the scope of not impairing the effects of the present invention.

       Next will be described with respect to zinc oxide coated on the zeolite surface.

       As the UV blocking agent of the present invention, zinc oxide, which is advantageous in terms of dispersibility compared to titanium oxide, was used. When the size of the zinc oxide particles is smaller than the wavelength of the visible light, the visible light may pass through the zinc oxide dispersion. In addition, zinc oxide effectively scatters and absorbs ultraviolet rays as the particle size decreases. Therefore, it is excellent in dispersibility and manufacturing nano-sized zinc oxide particles is advantageous in the ultraviolet absorption and visible light transmission drawings.

       Examples of the method for producing the zinc oxide particles include a gas phase method and a coprecipitation method.

      Next, the present invention has been described in detail for a fiber coating composition including AgZnH-zeolite prepared by the above method.

      The fiber coating composition of the present invention is the fiber coating composition of the present invention 0.2 to 2 parts by weight of the AgZnH- zeolite particles, 100 parts by weight of the total fiber coating composition, 1 to 10 parts by weight of the aqueous acrylic binder, dilution 60 To 90 parts by weight, 2 to 5 parts by weight of dispersant and 2 to 5 parts by weight of other additives.

      The aqueous acrylic binder is made by polymerizing various acrylic monomers, and is colorless, transparent, and hardly discolored. The aqueous acrylic binder is used by copolymerizing monomers containing acrylic acid and methacrylic acid derivatives in detail. Specifically, methacrylate, butyl methacrylate, hexyl methacrylate, octyl methacrylate, styrene, acrylic acid, methacrylic acid, Glycidyl acrylate, glycidyl methacrylate, hydroxyethyl acrylate, hydroxyethyl methacrylate, hydroxypropyl acrylate, hydroxypropyl methacrylate, acetone acrylamide can be used by copolymerizing.

      The dispersant is for the AgZnH-zeolite to be uniformly dispersed in the aqueous acrylic resin. As the dispersant, one or more selected from acryl, fluorine, siloxane, aqueous, naphthalene and the like can be used.

      The diluent is added to control the viscosity of the sunscreen composition is not particularly limited as long as it meets the purpose of the present invention, but specific examples, such as secondary distilled water, tertiary distilled water, isopropylalcohol, EC (Ethyl) One or more selected from Cellosolve), ethanol or MEK (MethylEthylKetone) may be used.

      The flame-retardant resin composition of the present invention can be suitably blended with other additives in addition to the above components. The other additives include, for example, tris (nonylphenyl) phosphite or tris (2,4-di-tetra-butylphenyl) phosphite (Tris (2,4-di-tert-). antioxidants such as butylphenyl) Phosphite); Alkylamine derivatives, acrylic or alkyl phosphate antistatic agents; Pigments such as zinc oxide, titanium dioxide, lead chromate, yellow iron oxide, chromium, molybdenum, carbon black; Blowing agents such as 5-phenyltetrazole, sodium bicarbonate, p-toluenesulfonylhydride, and p-toluenesulfonyl semicarbazide; Phthalic acid type, trimellitic acid type, phosphite type, epoxy type, polyester type, aliphatic type, anti-chlorine plasticizer; Fillers such as talc, feldspar powder, barite, vermiculite, mica, gypsum and magnesium oxide; Reinforcing agents such as silanes, silicones, siloxanes, cross-linking agents such as di- (2,4-dichlorobenzoyl) -peroxide, dibenzoylperoxide, tetra-butylperoxybenzoate, dicumylperoxide, benzophenone series, benzotria UV absorbers such as sol-based, salicylate-based, cyanoacrylate-based, and oxanilide-based, and lubricants such as fatty acids, inorganic, fluorine-based, and silicone-based compounds.
