Technical Field

The invention relates to the technical field of tea dyeing, in particular to a method for processing a chemical fiber fabric containing a tea extract.

Background

Tea refers to the leaves and buds of tea tree. Distinguished tea, cashew, tea, . Broadly refers to the leaves of the evergreen bush tea tree that can be used for tea making, as well as beverages infused with these leaves, later extended to all herbal teas infused with the plant flowers, leaves, seeds, roots, such as "chrysanthemum tea" and the like; "herb tea" and the like prepared by infusing various medicinal materials are also called Lei ya in Chinese literature. Some countries also have tea brewed from other plant leaves such as fruit and vanilla, such as "fruit tea".

Tea dyeing is one of plant dyeing processes, and also refers to finished products prepared by the processes. Because the materials are convenient to obtain and simple to operate, the method is suitable for most enthusiasts to do DIY, and is a good method for applying natural dyeing in industry, the materials are generally dyed by directly soaking fresh tea leaves or dry tea leaves and boiling to obtain liquor to be dyed in the existing tea dyeing process, the treatment mode cannot effectively obtain tea polyphenol in the tea leaves, so that the tea dyeing efficiency is low, the tea leaves are wasted to a certain degree, and the problem is solved by designing a method for processing the chemical fiber fabric containing the tea leaf extract.
