Method of manufacturing transfer sheet for dry dyeing of yarn {Method of Imprint Sheet for Waterless Dyeing Process}

The present invention relates to a method for manufacturing a transfer sheet used in a process of dyeing yarn using vacuum transfer, and more particularly, by repeatedly printing a dye ink for dyeing multiple times to laminate and apply an ink layer, It relates to a method of manufacturing a transfer sheet for anhydrous dyeing of yarns, which can prevent defects from spreading due to dye ink during the dyeing process by applying fine inorganic powder to the ink layer and drying it within a short time.

In general, in order to express various patterns or colors on fabric, a method of using different colored threads for warp and weft was used. However, in this method of fabric production, various changes could not be made because the pattern or color of the fabric was standardized. In order to obtain a unique image, the color also has a problem in that a lot of production cost increases because it goes through several stages of preparation.

In addition, in order to partially dye the yarn, a large number of dyeing tanks are provided and a number of winding processes are required, so many devices are required, and the installation cost is a factor that increases the production cost. Not only is it cumbersome, but there is a problem that dyeing in irregular shapes does not work well.

In order to solve this problem, the pigment is sprayed on the outer diameter part of the yarn wound on the bobbin in Republic of Korea Utility Model Registration No. 20-0334356, and vacuum suction is performed so that the sprayed pigment can be uniformly absorbed up to the inner diameter part. A multicolor dyeing apparatus capable of providing a yarn having a

However, since the conventional dyeing apparatus including the registered utility model uses a method of spraying or dipping a liquid mixed with a dye, a large amount of pollutants and a lot of wastewater are generated during the dyeing process, and therefore, it is necessary to purify the pollutants. Not only does it take a lot of time and money to reduce economic efficiency, but it is also difficult to completely purify, which adversely affects the environment.

Thus, the yarn is wound on a porous drum, the transfer sheet printed with dye ink is covered thereon, and vacuum pressure is generated through the inside of the drum to transfer the dye ink printed on the transfer sheet to the yarn so that it can be dyed. An anhydrous dyeing method of vacuum transfer method that can dye yarn without using water or liquid is being developed.

When performing this vacuum transfer anhydrous dyeing method, a sufficient amount of dye ink must be applied to the transfer sheet so that a large amount of yarn can be dyed with one or more desired colors, so the dye ink is laminated on the transfer sheet multiple times. do.

However, since the dye ink contains a preservative to prevent curing in the stored state, when the dye ink is printed and laminated multiple times, the ink layer becomes a sticky gel state by the preservative in the dye ink, If the transfer sheet is covered with the yarn in this state, the dye ink of the transfer sheet may be spread sideways or smeared on the yarn, so that the yarn may not be dyed with a desired color and pattern.

In addition, when printing ink on a transfer sheet using a conventional sublimation transfer printer, the sublimation transfer printer does not have a function to automatically return the transfer sheet to the initial position. Since the roll on which the transfer sheet is wound is rotated reversely, and after confirming the initial stage of the transfer sheet with the naked eye, the print operation takes a lot of time, and there is a problem in that the print quality is deteriorated due to low accuracy.
