Abstract

PURPOSE:To mold the shoes having the sole part of the color different from the color of the blade part over a long period of time by forming the transparent shoes body, then introducing colored opaque vinyl chloride plastisol into the sole part and molding the inner sole. CONSTITUTION:The shoes body 2 is molded by introducing the non-colored or colored transparent compounded vinyl plastisol into a slush forming mold 1 by the conventional method, then sticking the half gelatinized layer to the inside wall surface of the mold 1 under heating and discharging the ungelatinized plastisol. The inner sole 3 is formed by introducing a regulated amt. of the opaque vinyl chloride plastisol colored with pigments, dyes, etc., into the sole part 21 of the shoes body and gelatinizing the same under heating, thereby laminating and molding the gel on the front surface 211 of the sole part of the shoes body. The colored inner sole 3 is visible through the finished transparent shoes body and the appearance as if the sole part of the shoes is colored is obtd. The dislodging of the coating material by wear, etc., from the surface of the shoes body 2 is obviated at the time of wearing.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for forming slash shoes.

(Prior Art) Conventionally, a method of forming slush shoes with soles of a different color from the laces has been commonly used by applying colored paint to the surface of the soles of slush-molded shoes. However, when applying the colored paint, the laces must be masked, making the coloring process complicated, and since only the surface of the sole is colored with the colored paint, the surface tends to wear off during use. Or.

There was a drawback that the paint would fall off due to scratching, resulting in a mottled surface and a significant deterioration in appearance. The purpose is to provide a simple, long-lasting slush with a sole that has a different color from the laces and has a good appearance.

(Means for Solving the Problems) Below, the present invention will be explained with reference to drawings showing the state of implementation of the present invention.The present invention introduces transparent compounded vinyl plastisol into the slush mold 1 to make the shoe body 2 transparent.
The gist of the invention is a patented shoe molding method, which is characterized in that, after forming, a colored opaque vinyl chloride plastisol is further introduced into the sole 21 of the main body of the shoe to mold the inner sole 3. be.

In this invention, the transparent shoe main body 2 is made by introducing vinyl chloride plastisol containing either an uncolored transparent compound or a colored transparent compound into a slush molding mold 1 using a conventional method, and applying heat to adhere a semi-gelled layer to the inner wall surface of the mold 1. It is formed by expelling plastisol from non-gel shoes. And the inner sole 3 is
A predetermined amount of opaque vinyl chloride plastisol colored with pigments, dyes, etc. is introduced into the sole 21 of the shoe body formed in this way, and this is heated to gel, thereby being laminated on the upper bottom surface 211 of the shoe body. Although it is molded,
The inner sole 3 may be formed into a single layer, or may be made of a variety of unique vinyl chloride plastisols. ! The injection and gelation of each plastisol is repeated in stages, or vinyl chloride plastisol to which various types of pigments with different specific gravities are added is injected onto the upper bottom surface 211 of the shoe main body.
The pigment may be precipitated by the difference in specific gravity and then gelled to form a multi-layer, multi-color structure. The inner sole 3 formed in this manner may be formed over the entire sole 21 of the shoe main body, or may be formed over only a portion such as the heel.

(Effects of the Invention) As described above, the present invention can create a completed shoe by simply molding the shoe body 2 with transparent vinyl chloride plastisol and then molding the inner sole 3 with colored opaque vinyl chloride plastisol. The colored inner sole 3 of the shoe can be seen through the transparent shoe body, giving the appearance as if the sole was colored. In addition, since the colored inner sole 3 is covered with the transparent shoe body 2, even if the surface of the shoe body 2 is worn or scratched when worn, the color will not change due to paint coming off like in the past. The surface of the sole of the shoe does not become mottled and the appearance deteriorates.

Furthermore, the coloring work can be done simultaneously with the conventional inner sole molding work, so it is easy.

Example formulation Plus for shoe main molding Plastisol for inner sole molding ('It part) Thisol (coulometric part) PvC paste resin 100 100 plasticizer
8065 Stabilizer 22 Pigment 0.8 The above plastisol for forming the main body of shoes is introduced into slush molding mold 1, heated at 100°C for 4 minutes to adhere a semi-gelled layer to the inner wall of the mold, and then molded into non-gelled shoes. After discharging the plastisol and forming a transparent shoe main body 2, a prescribed amount of the above-mentioned plastisol for forming the inner sole (lt core) was introduced into the bottom 2111 of the shoe main body and heated at 100°C for 10 minutes.
After heating for a minute to completely gelatinize the inner sole 3 and the shoe main body 2, the completed slash shoe was removed from the mold. In this way, in the examples, the desired slash shoes of the present invention could be obtained.
