JPH05164996A - Production of spectacle parts made of pseudoantique-tone resin - Google Patents

Abstract

PURPOSE:To easily obtain spectacle parts made of resin having a pseudoantigue tone by molding the resin to the shape of the spectacle parts, then coloring at least a part thereof and partially polishing away the colored layer CONSTITUTION:The resin having a golden brown color is molded to the shape of the front frame of the spectacles. Such resin molding 11 is dyed to the color separate from the color of the resin itself, more specifically the color of a dark brown system dimmer than the color of the resin itself by using disperse dyes. Only the surface layer of the resin is discolored at the time of the dyeing. In succession, the dyed resin molding 12 is partially polished by buff to partially expose the undyed resin layer from below the dyed layer to speckle the entire part. The polished molding 13 is thereafter finished by coating the molding with matte lacquer, by which the resin spectacle parts having the feeling of an antique are produced. A method of previously providing ruggedness on the resin spectacle parts and polishing away the projecting part after coloration may be adopted in such a case.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing resin eyeglass parts having an antique-like decoration.

[0002]

2. Description of the Related Art In recent years, an eyeglass frame with an antique appearance has been popular as an antique. However, most of these antique eyeglass frames are made of metal, and rarely made of resin.

[0003]

Therefore, it is a technical object of the present invention to provide antique resin eyeglasses.

[0004]

In the present invention, after molding a resin into the shape of an eyeglass component, at least a part thereof is colored, and the colored layer is partially removed by polishing, or, By coloring the resin molded product with irregularities, removing the convex part and partially removing the colored layer, we manufacture eyeglass parts with antique-like decoration, by which the antique resin eyeglasses are produced. I tried to offer.

[0005]

EXAMPLES The present invention will be described below based on examples.

[0006] The resin of Example gold brown molded into the shape of the front frame of the spectacles. Next, the resin molded body 11 using a disperse dye,
It is dyed in a color different from that of the resin itself, specifically, a darker brown color than the color of the resin itself. In this dyeing, only the surface layer of the resin, more specifically 10
Discolor in the range of ~ 20μ. Subsequently, the dyed resin molded body 12 is partially polished with a buff to partially expose the undyed resin layer from under the dyed layer to make the whole mottled. After that, if the polished molded body 13 is coated with a matt lacquer to a film thickness of about 20 to 40 μm to finish it, it is possible to manufacture resin eyeglass parts having a feeling of antique.

[0007] In the same manner as Example Example, the colored resin is formed into the shape of the front frame of the spectacles. Next, this resin molded body 21
Is dyed in a patchy color different from that of the resin itself. In this dyeing, only the surface layer of the resin is changed in color. Subsequently, the mottled dyed resin molded body 22 is buffed and finished by coating with a lacquer with a gloss, whereby resin eyeglass parts having a feeling of antique can be manufactured.

[0008] In Example injection molding to obtain a resin molded body 3 having irregularities. This resin molded body 3 has protrusions at several places as compared with the finished eyeglass component, and when the protrusion is removed after dyeing the entire molded body, an eyeglass component 4 similar to the above two examples is obtained. .

[0009]

As described above, according to the manufacturing method of the present invention, it is possible to easily manufacture the pseudo old-fashioned resin eyeglass parts. Then, if spectacles are manufactured using the spectacle parts, it is possible to easily obtain antique resin spectacles. As described above, the manufacturing method of the eyeglass component of the present invention has high industrial utility value.
