Description

Multifunctional leather fabric {MULTIFUNCTIONAL LEATHER CRUST}

The present invention relates to a multifunctional leather fabric, and more specifically, the coating layer formed to protect the surface of the leather contains a porous material adsorbent and photoactive complexes, insect repellent, antibacterial, deodorization, breathability, far-infrared radiation, The present invention relates to a multifunctional leather fabric having various functions such as preservation and sustained release of fragrance.

Generally, natural leather is manufactured by processing raw leather, and synthetic leather refers to the coating of nylon on a sponge-like vinyl chloride leather and a substitute for leather developed after that, also called artificial leather.

In such leather, discoloration and blending often occur due to various factors such as washing, heat, friction, and absorption.

Accordingly, in order to improve the water resistance, abrasion resistance, tensile strength, and the like while protecting the surface of the leather from scratches, contamination, water penetration, and the like, a urethane resin or the like has been used for the coating layer.

However, the coating layer formed by the urethane resin as described above can not effectively block the various odors, stains or bacteria propagation, etc. generated during the long-term use of the peculiar smell of leather, as well as the frequent washing due to the contamination of the leather fabric Discoloration also had a problem that results in damaging the leather fabric.

The present invention has been devised in view of the above problems, the conventional coating layer formed to protect the surface of the leather, including the silica gel, zeolite, apatite, charcoal, ganban stone and other adsorbents and photoactive complexes, including insect repellent, Its purpose is to provide a multifunctional leather fabric having various functions such as sterilization and antibacterial, deodorization, securing breathability, far-infrared radiation, preservation and sustained release of fragrance.

10 ... Leather 100 ... Coating Layer

The present invention for achieving the above object, in the leather, the surface of the leather is characterized in that the coating layer containing the urethane resin, the adsorbent and the photoactive complex is compressed or adhered.

The coating layer is characterized in that the mixture of the adsorbent and the photoactive complex is impregnated in the urethane resin at a ratio of 1 to 10: 100.

The adsorbent and the photoactive complex are characterized in that the mixture at a ratio of 1: 0.01 ~ 0.5.

The adsorbent is characterized in that one or two or more of silica gel, zeolite, apatite, charcoal and elvan are combined.

Hereinafter, with reference to the accompanying drawings, a multifunctional leather fabric according to a preferred embodiment of the present invention will be described in detail.

1 is a side cross-sectional view schematically showing a multifunctional leather fabric according to a preferred embodiment of the present invention.

As shown in FIG. 1, the coating layer 100 is formed on the surface of the leather 10 according to the present invention to protect the leather 10 from an external environment, and the coating layer 100 is porous to a urethane resin. It is made by impregnating a material adsorbent and a photoactive complex.

Here, the adsorbent is composed of one or two or more of silica gel, zeolite, apatite, charcoal and elvan.

As the photoactive complex, it is preferable to use a material described in Korean Patent Application No. 2001-67887 filed by the present applicant (name of the invention: a multifunctional composite material). In brief, the photoactive complex may be visible light. And a multifunctional composite material having excellent ultraviolet absorption function, the surface of which is composed of a porous material such as elvan, zeolite, silica, activated carbon, apatite or clay such as bentonite, montmorillonite, kaolin, etc. It is coated or impregnated with an oxide that is specifically designed to provide excellent absorption of visible light and ultraviolet rays. Therefore, it exhibits excellent photoactivity even in the dark as well as outdoors, so it can be used regardless of time and place even when used as a solid acid, deodorant, antibacterial and disinfectant. The multifunctional composite material which shows activity .

[A _a D _d E _e O _x ] _y [Support] _z (Formula 1)

In Chemical Formula 1, A is at least one element selected from titanium, zinc, zirconium, vanadium, tungsten, and cerium; D is at least one element selected from iron, tin, vanadium, chromium, aluminum, silver, copper, molybdenum, antimony, niobium and silicon; E is at least one compound selected from sulfuric acid, phosphoric acid, boric acid, hydrogen fluoride, ammonium sulfate, fluorocarbon compounds and heteropoly compounds; a, d and e represent the molar ratios of the respective element elements, where a / (d + e) is 0.001 to 100, wherein d is in the range of 0 to 1; e ranges from 0 to 1; a ?? Is a value of 0; y / z> 0; x is a value determined to fit the valence.

The adsorbent and the photoactive complex are mixed at a ratio of 1: 0.01 to 0.5, and when the weight of the urethane resin is 100, a mixture of the adsorbent and the photoactive complex is impregnated with the urethane resin at a ratio of 1 to 10 so as to be fine. The coating layer 100 is formed with pores.

Such a coating layer 100 may be pressed to the surface of the leather by pressing (pressing) or may be attached with a fixed body or a chemical adhesive or the like.

In addition, by applying a variety of commercially available fragrances to the coating layer 100 as described above, the adsorbent may contain a fragrance to slowly and continuously diverge.

Hereinafter, the operation of the multifunctional leather fabric configured as described above will be briefly described.

First, the urethane resin of the coating layer 100 serves to protect the surface of the leather 10, the adsorbent impregnated in the urethane resin is attached to the coating layer 100 is an organic substance that causes a bad smell Or adsorption of inorganic substances to facilitate the reaction of the photoactive complex, and at the same time absorbs and decomposes various odors and emits far-infrared rays, which are beneficial to the human body.

In addition, the photoactive complex has excellent characteristics of absorbing visible light and ultraviolet rays, and thus exhibits excellent photoactivity in outdoor as well as dark rooms, and has a characteristic of continuously maintaining activity as a solid acid, a deodorant, an antibacterial agent, and a disinfectant.

When comparing the performance of the conventional leather fabric and the leather fabric of the present invention through the experiment is shown in Table 1 below.
