ACID DYES FOR DYEING OF TEXTILE DRY REFORMING DIACETATE METHOD AND HOW IT PRINTING THROUGH

摘要

PURPOSE: A dry modification method of a diacetate fiber for textile printing with an acid dye is provided to enable continuous working, to improve production efficiency, and to save water and energy. CONSTITUTION: A dry modification method of a diacetate fiber for textile printing with an acid dye comprises: a step of inputting the diacetate fiber into a tentering machine using water containing a seleno element of chemical formula 1 for padding and pretreating; and a step of drying with hot wind at 120 deg.C. for 3 minutes or less. The concentration of the seleno element is 10%-16%. The pretreatment is performed by adding a solubilizer of chemical formula 2. A textile printing method comprises: a step of inputting the diacetate fiber into a tentering machine using water containing a seleno element and pretreating; a step of drying with hot wind; a step of printing a textile using the acid dye; a step of drying the printed diacetate fiber; a step of steaming, washing, and drying the diacetate fiber.
