Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a mold/esobos plate for manufacturing a synthetic resin lace having unevenness of different levels.

Manufacturing methods for synthetic resin lace are generally divided into the following three types.

■ A method of printing a lace pattern on release paper and then peeling it off.

■ A method of embossing a synthetic resin sheet with an embossing plate and then slicing the recesses.

■ A method of filling an intaglio mold with PVC paste, scraping off unnecessary parts with a doctor, and then solidifying the paste and peeling it off.

Among these methods, it is difficult to obtain a lace having unevenness of different stages.

By providing concave portions with different levels of depth in the embossing plate (2) and the mold (2), a lace having unevenness with different levels can be obtained. As a method for providing the recessed portions, there is a method in which the lace pattern is indented by etching, and then the recessed portions or convex portions are partially corroded using a brush or the like. However, in this method, the corrosion caused by brushing is carried out manually, so the workability is poor and it is difficult to remanufacture exactly the same plate. Another method is to use the conventional method of gravure plate making, but in this method, the desired depth cannot be obtained because the carbon tissue cannot withstand deep etching of 100 mm or more. There is also a method of engraving, but it has many disadvantages such as being expensive and taking time to create. The present invention has been made to eliminate these drawbacks, and uses photolithography to intaglio intaglio patterns with different depths divided into several parts.

Next, the present invention will be explained with reference to the drawings. First, a pattern as shown in FIG. 2 is intaglio-engraved on a metal material as shown in FIG. 1 by photolithography. Next, as shown in Fig. 3, a chemical-resistant mold release resin is applied to the entire surface of the metal material so that the indentations are filled in, and then, as shown in Fig. 4, only the convex surfaces are polished. Expose and smooth the entire surface. Next, as shown in Fig. 5, another pattern is intaglio-engraved to a depth different from that of the intaglio by photolithography, and then, as shown in Fig. 6, the resin in the intaglio is swollen, dissolved, etc. By releasing the mold through the treatment of 2.
Manufacture molds and embossing plates for manufacturing synthetic resin lace with stepped unevenness. Moreover, by repeating the method shown in FIGS. 1 to 6 several times, a mold and embossing plate for manufacturing synthetic resin lace having concave portions with different depths in many stages as shown in FIG. 7 can be obtained. Manufacture.

The metal material may be any metal, such as copper, iron, zinc, etc., as long as it can corrode quickly and does not have significant side etching.

The photosensitive agent may be any photosensitive liquid used in photolithography as long as it can withstand corrosion up to several hundred microns.

The template resin may be any resin as long as it can withstand chemicals used in photolithography such as photosensitive agents, developers, and corrosive liquids, and can be released from the mold by subsequent treatment such as swelling and dissolution, such as epoxy resin. can be used. The mold/embossing plate manufactured by the above method is not only manufactured in a short time and at low cost because it is intaglio-engraved using the normal photoengraving method, but also is almost identical because it does not rely on human manual labor to prevent corrosion etc. It is easy to manufacture the mold and embossing plate again. This mold and embossing plate can be used as a molding material when manufacturing synthetic resin lace.
It can also be used as an embossed version. Example 1> From the lace pattern shown in Fig. 8, the disassembled positive No. 1
(Figure 9), No. 2 (Figure 10).

This disassembled positive M. 1 was placed in close contact with a 5-wall thick steel plate coated with a PVA thinnermate photosensitive solution, exposed and developed to obtain an image, and then the areas without resist were coated with dichloride to a depth of about 750mm. Corrosion was carried out with iron corrosive liquid. After the engraved portions are obtained, epoxy resin is applied to the copper surface so as to fill the engraved portions, and after hardening, only the surface of the convex portions is exposed and at the same time, the entire surface is polished smooth. Next, a PVA thinnermate-based photosensitive liquid was applied, and the decomposition was positive. 2 was used to corrode the mold to a depth of 300 mm, and then the epoxy resin within the indentation was removed using an epoxy resin swelling agent to obtain a mold for a synthetic resin lace having two levels of depth. After performing sandblasting, chrome plating, etc. on this mold, only the recesses were filled with resin of the following composition, heated at 200 qo for 3 minutes to gel the resin, and when peeled from the mold, it showed unevenness with different steps. As a result, a synthetic resin lace with a pus-filled appearance that at first glance could be mistaken for cotton lace was obtained. or,
This mold could also be used as an embossing plate.
