MULTIPLE COLOR PRINTING APPARATUS FOR LONG FIBER

摘要

PURPOSE: A multiple color printing apparatus for long fiber is provided to simplify printing procedures and reduce manufacturing cost, while obtaining large amount of yarns with multiple colors in a short time period. CONSTITUTION: A dry rack(30) is interposed between a yarn supply winder(10) and a cone winder(20). A multiple color printing roller(40) includes a plurality of pockets formed along the outer periphery of a cylinder having a large diameter; a stamp chamber for filling a stamp layer(46) formed by blocking a support plate which has a plurality of nozzles; and ink injection pipes(49) connected to the pockets, and which inject ink through a check valve(48). The multiple color printing roller is arranged in a vertical direction between the yarn supply winder and the dry rack, and a yarn(P) passes through the gap between stamp layers of upper and lower rollers. Thus, a single ply of yarn is printed in multiple colors at a constant interval.
