Abstract

The invention provides a method for preparing a natural dye mordanting dyeing or mordanting printing product. The preparation method comprises the steps of performing pretreatment on a fabric, using cation modified working solution to perform cation modification on the fabric, and obtaining cation-modified fabric; using natural dye to dye the cation-modified fabric and obtaining a natural dye dyeing fabric; using a mordant working solution or mordant working solution foam to perform mordanting dyeing or mordanting printing on the natural dye dyeing fabric at a predetermined area, performing steaming or baking at 80-180 DEG C for 10 s to 25 min, performing washing, softening and shaping, and obtaining the natural dye mordanting dyeing or mordanting printing product. The invention further provides the natural dye mordanting dyeing or mordanting printing product obtained according to the preparation method. The natural dye mordanting dyeing or mordanting printing product obtained according to the preparation method is good in color fastness and uniform in base color, the printing part is dark in color, the material loss is less, and a fabric is softer.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a natural dye mordant printing product and a preparation method thereof. Background technique [0002] Natural dyes refer to dyes obtained from plants, animals or mineral resources without artificial synthesis and little or no chemical processing. Because it can be regenerated, it meets the requirements of sustainable development and environmental protection, and the printed product pattern obtained by printing with natural dyes is attractive and varied. It belongs to a higher-end product and is widely loved by people. [0003] Conventional natural dye printing products are mainly printed by tie-dyeing and batik, but the process is complicated. Since the conventional printing method uses slurry printing, the slurry and the mordant are prone to react and produce precipitation, so mordant printing cannot be used. In addition, conventional mordant dyeing methods ...
