Problems solved by technology

[0005] The current production of berry tea can only use part of the young stems and leaves. A large number of branches and leaves are produced due to pruning and shaping every year. Because the branches are too thick, aging, and the taste is not good, they cannot be used to make tea and can only be used as waste. Let it rot naturally, which significantly reduces the resource utilization value of berry tea

Embodiment 1

[0070] Embodiment 1 alum is the same bath mordant of mordant (aluminum mordant dyeing)

[0071] Take 50ml of the liquid raspberry tea dye obtained in Preparation Example 1, add 1L of water, and heat to 60°C while stirring to fully dissolve it to form a raspberry tea dye solution, put it in a dyeing vat, add 4g of alum as a mordant in the dyeing vat; take the dye to be dyed The fabric (the fabric is soaked with water in advance, dried or wrung out) is placed in the dyeing solution, and dyed at 60°C for 10 minutes. During this period, the fabric is continuously adjusted to make the dyeing uniform. After 10 minutes, take it out, squeeze out excess water, dry it slightly, and wash it fully with water. Wash away the floating color and dry it.

Abstract

The invention belongs to the technical field of dye preparation, and particularly relates to an agricultural waste plant dye and a preparation method and application thereof in cloth dyeing. The plant raw materials of the agricultural waste plant dye comprise wastes generated in a Ampelopsis grossedentata tea processing process and stems and leaves of polygonum hydropiper. The preparation method comprises the following steps: mixing the plant raw materials, carrying out enzymolysis, alcohol extraction, concentration and chromatographic separation, concentrating to obtain a liquid dye, and drying to obtain dye powder. According to the invention, wastes generated in the production of the Ampelopsis grossedentata tea are developed into a plant dye, so that the resource utilization value of the Ampelopsis grossedentata tea is improved, and meanwhile, a green, natural and non-toxic dye is obtained.

Description

technical field [0001] The invention belongs to the technical field of dye preparation, and in particular relates to a berry tea agricultural waste plant dye and the application of the preparation method in cloth dyeing. Background technique [0002] In addition to the agricultural products harvested as the target, agricultural production also produces a large amount of agricultural waste. These agricultural wastes have no economic value, are huge in quantity and are scattered in the vast countryside, becoming the main source of pollution affecting the rural ecological environment. The natural decay of agricultural wastes is also a process of increasing carbon emissions. [0003] Unlike industrial "three wastes", most agricultural wastes are non-toxic and harmless. The main reason why agricultural wastes are difficult to harmless treatment is that they are worthless or low-value, highly dispersed, and used in urban or industrial governance methods Economically unfeasible an...
