伝統技法『絞りの絵付け•型彫り』工程のCAD/CAMシステムの開発

摘要

This research is aimed at developing a computer aided design system for a traditional tie-dyeing craft named "Shibori". These products of folk crafts are made with the manual labors and their processes are divided into a lot of practiced hand works. In addition their manufacturing processes are dispersed to different regions. So the practiced hand works of the "Drawing/Pattern carving Shibori" process decrease in number. Producing Shibori products may become difficult because anyone cannot plan the Shibori products in the future. If the "Drawing/Pattern carving Shibori" process is simplified by computerizing, we can record the Shibori technology and can also design Shibori products easily. In this report, therefore, we developed both a CAD system for "Drawing" process in order to simplify its process and keep skilled hands of Shibori products, and a CAM system for "Pattern carving Shibori" process using CAD data. This CAD system is useful for "Mokume-Shibori" to make their stitch images by means of its small scale modification. This report also provides an overview of a CAD system for "Mokume-Shibori" to make their stitch images and a CAM system to make its trial fabric.%伝統技法『絞り』の一手法である『有松•鳴海絞り』では製品の生産をFig.1に示すように，絵付け•型彫り•括り•染め•縫製の各工程に分業化し，産業として発展させ栄えてきた歴史がある.しかし現状では『絞り』の加工費削減のため，括りの工程は中国など海外で行われている.各工程の作業地域が分散し,絞り製品の企画設計に相当する絵付け•型彫り工程の担い手がいなくなっている.そのため将来的に絞り製品の企画設計が行えず.製品の生産が困難になることが考えられる.
