Problems solved by technology

[0008] As seen in Table 1, the main problem faced by the prior art is how to improve the color fastness of plant dyed fibers or fabrics, especially the color fastness to water, the color fastness to artificial light, the color fastness to saliva, and the color fastness to saliva. Poor abrasiveness and other technical problems; at the same time, because pure cotton fabrics contain more natural cellulose, microorganisms are easy to survive, therefore, microorganisms have a greater destructive effect on cotton fabrics, especially not resistant to mold

The plant-sourced compound functional herbal cotton fibre provided by the invention has good colour fastness.

Description

technical field [0001] The invention relates to a cotton fiber and a preparation method thereof, in particular to a plant-source composite functional herbal cotton fiber and a preparation method thereof, belonging to the field of textiles. Background technique [0002] Natural plant dyes are extracted from the flowers, leaves, stems, roots and fruits of plants, which have good compatibility with the environment and are biodegradable. During the dyeing process, the medicine, fragrance and pigment components of plant dyes are absorbed by the fabric together, so that the dyed fabric has special medicine and health care functions for the human body. The application of plant dyes in our country has a history of thousands of years. As far back as the cave man period of the Paleolithic Age, people have used plant dyes to dye the stone beads of decorations. By the Ming and Qing dynasties, the planting of dye plants, dye extraction and preparation technology, and printing and dyeing...
