Description

[Detailed description of the invention]

Purpose of the Invention (Field of Industrial Application) This invention is made by flocking piles on the surface of various base materials such as automobile interior parts, indoor wall materials, and furniture made of synthetic resin, metal, wood, and other various materials. It concerns hair transplant products. (Prior art) Conventionally, in this type of flocked product, the flocked pile itself was colored, so the base material and the colors, patterns, letters, etc. applied to it were hidden, resulting in uniformity with little change in appearance. The colors and designs sometimes lacked interest. In addition, in order to add letters and patterns to this conventional product, there were some that applied pressing, printing, and spin processing to the pile after flocking, but this increased the number of steps and caused problems in terms of workability, cost, etc. Not only that, but it also had the disadvantage that the softness of the pile was impaired. (Problems to be Solved by the Invention) Therefore, the inventor of the present application has recently provided a transparent or colored transparent adhesive layer on the surface of the base material, and electrostatically flocked a transparent or colored transparent pile to solve the above problem. The company has invented a flocked hair product that solves these problems, but the problem with this hair flocked product is: what colors, patterns, letters, etc. can be applied to achieve a varied and excellent appearance? That's what happened. Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention uses a color-changing material that changes color depending on the environment to color the base material.
In addition to applying patterns, letters, etc., a transparent or colored transparent adhesive layer is provided on the surface of the base material, and the pile is electrostatically flocked so that the color, pattern, letters, etc. of the base material can be visually recognized. . (Function) Colors, patterns, letters, etc. applied to the base material change color depending on the temperature, humidity, or light of the environment, and the same color, pattern,
Since the letters etc. can be seen through the pile, the appearance is varied. Moreover, the softness of the pile surface is also maintained. (First Embodiment) A first embodiment in which the present invention is applied to an interior material for a center pillar of an automobile will be described below with reference to FIGS. 1 and 2. Reference numeral 1 denotes an interior material of the center pillar as a base material, which is made by injection molding of a milky white colored synthetic resin. Reference numeral 2 denotes a printed portion of colors, patterns, characters, etc. formed on the surface of the interior material 1, and is made of a color-changing material that changes color depending on the environment. This color-changing material includes materials that change color depending on temperature (this phenomenon is called thermochromism),
A material that changes color due to humidity or a material that changes color due to light is used. This color-changing material will be explained in detail below. First, as a thermochromic material, it is possible to use a temperature-indicating paint that utilizes the property of changing color due to a chemical change occurring at a certain temperature. There are two types of temperature-indicating paints: reversible paints that change color due to heating and change color when cooled, and irreversible paints that do not change color even after cooling. Examples of reversible temperature-indicating paints include metals (mercury,
Color-changing pigments made of halides, complex salts, double salts, organic acetates, etc. of silver, copper, etc.) are mixed in vehicles such as lacquer, vinyl resin, alkyd resin, silicone resin, etc. . Examples of irreversible temperature-indicating paints include metals (cobalt, nickel, etc.)
There are examples in which color-changing pigments made of carbonates, sulfides, ammonium salts, etc. are mixed in the above vehicle. This example is characterized by a change in appearance, so
The former type of reversible temperature-indicating paint is particularly suitable. Another thermochromic material that can be used is a liquid crystal called a cholesteric crystal, which utilizes the property of exhibiting a light interference reflection phenomenon in a specific temperature range. Next, as a material that changes color due to humidity, a material that loses crystal water and changes color can be used. This material absorbs humidity in the air and changes color due to recoloring. Next, as a material that changes color when exposed to light, a photosensitive substance such as silver halide, silver nitrate, or diazo compound can be used. 3 is a transparent or colored transparent adhesive layer coated on the surface of the interior material 1, and is made of acrylic,
Various adhesives such as epoxy are used. That is, the adhesive used for this adhesive layer 3 is:
It is sufficient that the material has a transparency that allows the interior material 1 and the printed portion 2 to be seen through when it is stretched into a thin layer. 4 is a transparent or colored transparent pile that is electrostatically flocked on the upper surface of the adhesive layer 3, and as described above,
It is sufficient that the interior material 1 and the printed part 2 have transparency to the extent that they can be seen through. Fibers made of various materials such as nylon, acrylic, polypropylene, and polyester can be used for the pile 4. In addition, super bright, bright, semi-dull, and full dull can be used for pile 4 in relation to the raw material raster, but the less the amount of matting agent added, the higher the transparency, so super bright and bright are better. Preferably used. The shorter and finer the fiber length and fineness of the pile 4, the greater the transparency effect of colors, patterns, letters, etc., but they may be appropriately selected in consideration of the relationship with the raised physical properties and transparency. Generally, a fineness of 1 to 50 deniers and a fiber length of 0.3 to 10 mm are preferably used. Furthermore, the form of the pile 4 is not limited to the straight type as shown in Figure 2, but also the curl type as shown in Figure 10 or the crimp type as shown in Figure 11. can be used. Regarding the relationship between these pile forms and flocking density,
As an example, Table 1 shows hair transplanted under the following conditions. Pile Nylon-6 (semi-dull) Pile fineness 3 denier, fiber length 1mm Base material ABS resin flat plate Flocking conditions Pole spacing 75mm Voltage (DC) 2.5KV Flocking binder (adhesive) Acrylic resin emulsion Curing ring 80℃ x 20 minutes

[Table] As a result, compared to the straight type, curl type and crimp type piles are grafted with an increased fiber space.
The hair becomes coarse and the flocking density decreases. Therefore, the lower the flocking density, such as the crimp type, the better the color,
The perspective effect of patterns, letters, etc. becomes greater. Desirably, such piles have an average of 10 to 40 crimps per inch, preferably 20 to 35 crimps per inch. Further, the crimp may have any angle such as an obtuse angle, an acute angle, or a curled angle, but preferably the bent portion has a buckled shape with an angle. Moreover, these straight type, curl type, and crimp type can be mixed and used in any ratio as required. In this embodiment, the printed part 2 applied to the base material changes color due to temperature, humidity, or light.
Since the colors, patterns, letters, etc. of the can be seen through the pile 4, an excellent and varied appearance can be obtained. In particular, when a thermochromic material is used for the printed part 2, the approximate temperature inside the car can be known from outside the car, which is effective as a kind of warning when the car is parked outdoors for a long time in the summer. In addition, interior material 1
The flat part and the side part of the screen appear to have different hues due to the difference in the angle at which the light rays strike, giving a sense of weight. Furthermore, in this example, the surface of the pile 4 is not subjected to any press processing or the like, and the texture of the pile 4 is maintained as it is, so that a soft touch can be obtained. Note that the pile 4 may be subjected to press processing, printing processing, spin processing, etc. within a range that does not impair its texture. Of course, various color coordinations are possible by combining the colors of the interior material 1 and the printed portion 2.
