Yes.

Utility Model Registration No. 3107650

In the color-processed product that has been subjected to Bengala dyeing proposed in Patent Document 1, a product with a bronze antique color can be obtained. Since the binder treatment is performed with a liquid or the like, the work process is complicated, and there is a problem that consideration is not given to changing the amount of bengara attached with the same color.

An object of the present invention is to provide a color processed product that solves the above-mentioned problems and has a natural texture that is effective in water resistance or wear in a simple work process.

The colored processed product for coloring the surface of the member to be colored according to the present invention is the colored processed product for coloring the surface of the member to be colored, wherein the surface of the member to be colored is mixed with casein and polyisocyanate that crosslinks casein to form a paste After being applied to a predetermined portion of the case, casein, a solvent of casein and a natural powder pigment are mixed and dispersed as a powder on the entire surface of the member to be colored, and then water is applied to the dispersed powder. The case where the natural powder pigment containing casein is dissolved to fix the natural powder pigment on the entire surface of the member to be colored, and the finishing treatment is performed, so that a lot of natural powder pigment adheres to the surface of the member to be colored. It is characterized in that pigments of the same color are distributed in the places where they are adhered to a small amount.

The natural powder pigment is bengara, and the casein solvent is borax.

Furthermore, the member to be colored is a denim material which is a fabric of jeans.

Further, the finishing treatment includes a coating treatment, wherein a coating layer is formed on the surface of a member to be colored which is distributed in the same color in a portion where a lot of natural powdered pigment adheres and a portion where the natural powder pigment adheres a little. .

According to the present invention, casein and polyisocyanate that crosslinks casein are mixed and applied as a paste to a predetermined portion of the surface of the member to be colored, and then mixed with casein, a solvent for casein, and a natural powder pigment. After spraying as a powder on the entire surface of the member to be colored, the sprayed powder is given moisture to dissolve the natural powder pigment containing casein, and the natural powder pigment is applied to the entire surface of the member to be colored. By fixing and finishing to the surface of the colored member, the same color pigment is distributed on the surface of the colored member by distributing the same colored pigment on the surface of the colored member on the surface where the natural powdered pigment is adhered to a small amount. Since the amount of the powder pigment adhering is changed, it is possible to provide a color-processed product that takes into consideration the natural texture with good durability and good design decoration. Furthermore, environmentally friendly colored processed products can be provided by selecting borax as a solvent for bengara and casein as natural powder pigments. Moreover, if applied to denim material, which is a fabric for jeans, products with an old color tone can be provided.

Embodiments of the present invention will be described below with reference to FIGS.

In the coating process 100 of casein containing polyisocyanate, casein and polyisocyanate that crosslinks casein are mixed and applied as a paste to a predetermined portion of the surface of the member 1 to be colored such as wood, cloth or Japanese paper The casein containing polyisocyanate having a predetermined pattern is distributed. In this case, 70% by weight of water, 17% by weight of casein, 8% of borax as a solvent for casein, and 5% by weight of polyisocyanate are mixed to form a paste.

Next, in the casein dispersion step 200 of casein-containing pigment, casein and borax or ammonia, which are solvents for this casein, are dispersed over the entire surface of the member 1 to be colored in the form of iron oxide, titanium oxide or carbon such as bengara. In this case, the casein and the pigment are powders of 0.5 μm and 0.7 μm mixed with 45 wt% casein, 5 wt% borax and ammonia, and 50 wt% polyisocyanate, respectively.

In the moisture application step 300, water is applied to the entire surface of the member 1 to be colored to give water to the dispersed powder to dissolve the natural powder pigment containing casein, thereby converting the natural powder pigment into the member to be colored. Let it settle on the whole surface. In this case, the method of supplying moisture for dissolving the natural powder pigment containing casein may be steam or water droplets instead of steam.

Next, in the finishing process 400, various methods can be selected depending on the application. For example, after heat-drying, heat-pressing or natural drying (drying step 401), washing with water or the like (washing step 402) and drying (drying step 403) are performed. This method is particularly suitable for a denim material in which the member to be colored is a jeans fabric, and can provide a product with an old color tone.

Further, in the cleaning step 402, water may be used, followed by heat drying, heat pressurization, or natural drying (drying step 401), followed by sieving. This method can be widely used for fiber materials such as wood, cloth and Japanese paper.

If the coating treatment step 404 is added to the finishing treatment step 400, the natural powder pigment is further peeled off from the surface of the member to be colored which is distributed in the same color at the places where a lot of natural powder pigments adhere and the places where the natural powder pigments adhere little. It becomes difficult. For example, after drying (drying step 403), when a method of forming a coating layer with a natural varnish such as shellac varnish, lacquer varnish or straw shibu varnish (coating treatment step 404), a lot of natural powder pigments adhered. It is possible to provide a color-processed product in which the natural powder pigment is difficult to peel off from the surface of the member to be colored, which is distributed in the same color in the part and the part that adheres little, and the secular change of the coloring effect is maintained. In this case, by using natural varnish as a material for forming the coating layer, it is possible to provide an environment-friendly colored processed product together with natural powder pigment.

Moreover, if it is wood and paper, natural drying may be sufficient without using the heating process.

By the above procedure, as shown in FIG. 2, casein and polyisocyanate that crosslinks casein are mixed and applied as a paste to the surface of the member 1 to be colored, and a lot of natural powder pigment adheres to the part 2, The amount of the natural powder pigment adhering to the portion 3 is reduced, and a colored product having the same color and the natural powder pigment adhering amount is changed.

Next, a color processing method for performing color processing on a member to be colored using bengara as a natural pigment will be described.

70% by weight of water, 17% by weight of casein, 8% of borax, and 5% of polyisocyanate are mixed and applied as a paste to a predetermined portion 2 on the surface of the member 1 to be colored (application step 100 of casein containing polyisocyanate). ). Next, powder mixed in a ratio of 45% by weight of casein, 5% of borax, and 50% of bengara is sprayed on the entire surface of the member 1 to be colored (spreading process 200 of pigment containing casein). Subsequently, when water vapor is attached to the entire surface of the member to be colored 1 of the cloth, moisture is given to the powder and the bengara is fixed on the entire surface of the member to be colored 1 of the cloth (moisture application step). Next, a portion where a large amount of bengara adheres to the surface of the member 1 to be colored by performing a finishing process of heating (drying step 401), washing with water (washing step 402), and drying (drying step 403). As a result, a colored processed product is obtained in which the amount of bengal adheres to the portion 3 where the amount of adhering is less than 2 and the amount of the bengal adherence is changed.

The present invention is a color processed product in which natural powder pigments are fixed on fiber materials such as wood, cloth and Japanese paper, clothing products such as jeans, wall materials, building materials such as balustrades and pillars, and art such as paintings. It can be used for goods.

It is a work process figure which shows the Example of this invention. It is a figure of color development.
