Description

Footwear ink manufacturing for double-color expression and footwear

The present invention relates to shoes such as slippers, sandals, shoes, etc. Particularly, shoes that express dual colors to stimulate children's taste and increase aesthetics along with product value or to prevent traffic accidents due to the splendor of colors It relates to a method for producing a dragon ink and a shoe thereof.

Conventional children's shoes (shoes, slippers, sandals, sneakers, etc.) express a variety of colors or form pictures or specific shapes on a single sole and the upper upper formed on the sole to create aesthetic effects. Increasing the marketability.

However, as the shape of the shoes designed by many classifications is added to the upper according to the characteristics of the shoes, many patterns of design are desired, and these pictures are easily forgotten by the children according to the changing fashion.

In addition, recently, luminous paint is applied to the upper of a shoe or paint is sprayed onto a specific part of the shoe so that it is painted at night to prevent the accident with aesthetic function by luminous paint. Patent registration No. 10-0328508 In the method of manufacturing multicolored patterned shoe sole, the resin foam is used to prepare a multicolored sponge shoe sole. The mixture of the state is prepared for each desired color, and the mixture of the plate-like dough or powder is finally put into each individual mold formed according to the shape of the desired shoe sole, so that the decomposition of the blowing agent and the reaction of the crosslinking agent in the injection molding machine or the press device Shoes are heated and pressurized to a temperature that does not occur And preparing each piece of dough according to the pattern letter and color, and finally injecting each piece of dough into the shoe sole or foam mold of the same type so as to exactly match the volume and shape, and foaming of the blowing agent and reaction of the crosslinking agent occur. It is known to manufacture a foam by heating and pressurizing for a predetermined time so as to manufacture a multi-colored foamed shoe sole by arranging the foam with a grinder, but this conventional technique is a plate-like mixture by mixing a mixture of appropriate materials with a mixer. Dough is produced according to the required color, and the dough is put into individual molds made according to some forms of the shoe sole, and the dough is formed at a temperature at which the decomposition of the blowing agent and the reaction of the crosslinking agent do not occur, and then each dough is foamed. Laminated to mold, heated to proper temperature, foamed and finished with grinder In order to produce a multi-colored patterned foam shoe sole, it is very difficult to manufacture and the degree of expressing a simple multi-color has not been greatly gained by young consumers.

Also In Utility Model Registration No. 20-0294889 Polyurethane and thermoplastic polyurethane are sequentially coated on the inner surfaces of both spun fabrics, and the edges of the two spun fabrics are hermetically bonded to form a sealed bag therein. The fragrance is difficult to diverge in the sachet so that the fragrance is emitted from the shoe by the configuration has been a disadvantage that the fragrance disappears within a short time.

The present invention devised to solve the above problems is a photosensitive pigment (Spirooxazinee dye) or Zion pigment (expressing a secondary pigment with a diluent cyclohexanone (C6H10O) in the medium (transparent medium) The ink is prepared by mixing the thermal chromium pigment.

The Zion pigment is composed of two components, an electron-donating material and an electron-accepting material, as shown in the figure. The zion pigment is colored in a state where both of them interact with each other to form a crystal. When the colored crystal is heated, the electron-accepting material is dissolved. The teaching action of the electrons disappears and they become colorless (transparent).

Accordingly, if an electron-accepting material having an arbitrary melting point is selected, the color and colorless change can be reversibly repeated several times at a predetermined temperature, and the principle of chemical and physical change can be applied as a reversible pigment. The color can be a combination of various colors by changing the electron donor material as a dye intermediate.

The present invention is printed on the first printing layer by the general ink on the upper of the shoe upper or the like, the Zion / photosensitizing pigment is mixed with Zion / photosensitizing pigments by expressing or colorless according to the temperature or ultraviolet rays Secondary colors and primary colors are represented repeatedly.

The shoe according to the present invention is an invention that is easy to manufacture because it increases the marketability to stimulate the eyes by varying the visual aesthetics of children by expressing the secondary color in the primary color by temperature or ultraviolet rays according to the additive pigments .

As described above, the present invention selects the Zion pigment and the photosensitive pigment which are changed by the ultraviolet rays, which are changed due to the temperature difference, and are mixed with the transparent medium, so that the discoloration changed by the characteristics thereof is expressed as the secondary color.

Embodiments of the present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

Example 1

80% by weight of a transparent medium;

10% by weight of a pigment selected from either a photosensitive pigment (Spirooxazinee dye) or a Zion pigment (Thermer Chromic Pigment) representing a secondary pigment;

A secondary ink is prepared by mixing 10% by weight of the diluent cyclohexanone (C6H10O; condensate).

A color change sensor is input to the photosensitive pigment and the zion pigment, and a dye for expressing a secondary color is selected.

Example 2

The method of printing on the shoe upper using the secondary ink is as follows.

As is well known, the primary paint layer 10 is gravure-printed or screen-printed with primary ink using a multicolor common to the shoe upper 100.

The secondary painting layer 20 is coated and printed by gravure printing using the above-described secondary ink on a predetermined portion of the primary painting layer 10, that is, at a position where the secondary color is to be expressed.

Example 3

The second upper 102 is configured to protect the printed layer by forming a transparent second upper 102 above the printed layer of the first and second printed first upper 101.

The shoe manufactured by the above is composed of two components, an electron donating material and an electron accepting material, as known according to the characteristics of the secondary pigment material, Zion pigment, and both of them interact with each other to show color in the state of crystallization. When the colored crystals are heated, the electron-accepting substance dissolves, and thus the electrons do not interact with each other.

After all, if an electron-accepting material having an arbitrary melting point is selected, it becomes possible to repeatedly change the color and colorless (transparent) color at a certain temperature, and use it as a reversible pigment by applying the principle of chemical and physical change. The color can be a combination of various colors by changing the electron donor material as a dye intermediate.

Since the Zion pigment is in a conventional technique and the manufacturer is freely inputting the Zion sensor according to the demand of the consumer, the technique and its description are omitted.

Since the Zion pigment used in the present invention as described above has a reaction temperature, the color develops when the ambient temperature corresponds to the reaction temperature of the Zion pigment.

That is, when the primary pigment layer 10 which is normally printed with a normal red pigment which is not affected by the change of temperature is formed, and the Zion pigment which is colored blue at 20 ° C. is printed as the secondary pigment layer 20. When the Zion sensor is formed, the color is developed at a temperature around 20 ° C, and the color is colored in Zion pigment blue. (The reaction temperature deviation of Zion Pigment is generally ± 2 ℃).

The present invention is applied to slippers for children to print pictures or letters on the upper of shoes.

Accordingly, in the morning when the temperature is below 20 ° C, a red picture representing the primary picture layer 10 of the primary pigment is expressed, and when the temperature rises above 20 ° C, the secondary picture layer of the secondary color of the slippers (20 ) Is changed to blue, which is the color of the morning and afternoon changes in the same sleeper.

In addition, when the secondary pigment material is used as a photosensitizer (Spirooxazinee dye), the photosensitizer is a photopolymer, which is a polymer or a polymer composition in which a change in molecular structure occurs due to the action of light, and consequently, changes in physical properties. It is known as a polymer.

According to the above properties, the photosensitive pigment added to the secondary pigment material is blue and the primary printed picture pigment is red. When the light is received outside the secondary pigments to express the blue by the action of light to represent the secondary picture layer (20).

Accordingly, the slippers express the different colors in the shade and the light position, and the mystique is exerted.

In the description of the present invention, the primary and secondary pigments are described in red and blue. However, the primary and secondary pigments are added in consideration of the mixing relationship of dichroic colors, and the like, in particular by three primary colors. Of course, the color selection should be made in consideration of the mixing relationship.

In addition, the present invention is composed of a second upper 102 to protect the printed layer by forming a transparent second upper 102 above the printed layer of the first and second printed first upper 101 to protect the printed layer. Along with the protection, it also prevents discoloration and abrasion so that it can exhibit aesthetic functions for a long time.

The present invention selects the Zion pigment and the photosensitive pigment which is changed by the temperature difference by the temperature difference, and mixed with the resin and print the picture with the printing ink of the shoe upper so that the discoloration changed by their characteristics to be expressed in the secondary color By drawing the second picture in the first picture by the temperature or ultraviolet rays according to the additive pigments, the visual appeal of the children is increased, thereby increasing the merchandise that stimulates the eyes and forming a transparent second shell on the printed layer. It prevents peeling off of paint or rapid discoloration and expresses vivid pictures for a long time and increases its use effect.It is used with sports shoes to inform the dangers of creating pictures at special-purpose workplaces or for sports. It is an invention that is easy to manufacture and the effect can be easily manufactured with the ink.
