Description

Printing color paste containing grape pigment and its printing process

technical field

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.

Background technique

With the gradual improvement of people's life modernization, protecting the common living environment of mankind and realizing sustainable development has gradually become the main direction of economic development in all countries in the world. People pay more and more attention to the safety and health of textiles and textile chemicals. Natural With its unique characteristics, pigments have once again attracted the attention of relevant researchers. They are popular for their safety, non-toxicity, good ecological and environmental protection effects, unique health care and medicinal functions, and natural coloring and hue.

Grape pigment widely exists in the wastes of wine and grape beverage production and processing. It has a wide range of sources, low price, and has a broad market prospect. Grape pigment has anti-ultraviolet and antibacterial functions, and also has certain medicinal and health care values. Grape pigment printing can not only obtain soft colors, but also endow fabrics with special medicinal and health care functions. At present, most studies focus on the performance and dyeing application of natural pigments. There is a lack of research on the application of natural pigments in printing, and the application of grape pigments in printing has not been reported.

Contents of the invention

The purpose of the present invention is to provide a printing paste containing grape pigment and its printing process for cotton fabrics and silk fabrics.
