Abstract

The invention discloses printing paste containing laccaic acid pigment and a printing technology for cotton fabric and silk fabric thereof. The printing paste containing the laccaic acid pigment is prepared from, by weight, 50-65% of starch raw paste, 2-5% of the laccaic acid pigment, 2-5% of urea, 1-4% of mordant and the balance water. The printing paste containing the laccaic acid pigment is adopted for carrying out printing on the cotton fabric according to the technology of printing, drying, steaming and aftertreatment; the printing paste containing the laccaic acid pigment is adopted for carrying out printing on the silk fabric with a pH value adjusted to be 4-5 according to the technology of printing, drying, steaming and aftertreatment, the printed fabric is bright in color and has an anti-ultraviolet function, laccaic acid pigment printing meets the requirements for ecology and environmental protection, the cotton fabric and the silk fabric printed through the laccaic acid pigment have good color fastness, and colors of printed products can be enriched by using different kinds of the mordant.

Description

technical field [0001] The invention belongs to the technical field of fabric printing, and in particular relates to a printing paste containing lac insect pigment and a printing process thereof. Background technique [0002] In recent years, human beings have paid more and more attention to global environmental issues, and the protection of human living environment and sustainable development have become the themes of world economic development. The concept of environmental protection has been deeply rooted in the hearts of the people, and people are paying more and more attention to the safety and health of textiles. Natural pigments have the advantages of good biodegradability, non-toxic, harmless, non-allergic to skin, non-carcinogenic, etc., and also have various functions such as drugs and spices. The fabrics printed and dyed by natural dyes not only have medicinal and health care effects on the human body, but also have unique hues and personalization, which are very...
