Abstract
The invention discloses a printing color paste containing grape pigment and a printing process on cotton and silk fabrics by using the same. The printing color paste containing grape pigment is made from the following raw materials by weight: 50-60% of gum dragon raw paste, 1.5-4% of a grape pigment, 2-4% of glycerol, 0.5-3% of a mordant and the balance of water. The printing process on cotton fabrics by using the printing color paste containing grape pigment is as below: printing, drying, steaming and posttreatment. The printing process on silk fabrics by using the printing color paste containing grape pigment is as below: adjusting the pH value to 4-5, printing, drying, steaming and posttreatment. The cotton fabrics and silk fabrics printed by grape pigment have soft color, good color fastness and a health care function; the grape pigment printing is in line with the ecological and environmental requirements; different mordants can enrich the tone of the printed products; and the environmentally friendly moisture absorption cosolvent glycerin makes the production process more environmentally friendly.
Description
technical field [0001] The invention belongs to the technical field of fabric printing, and in particular relates to a printing paste containing grape pigment and a printing process thereof.
