Embodiment 1

[0033] A process of dyeing hemp using Ume, including:

[0034] (1) Extraction process of Ume pigment: extraction by distilled aqueous solution, extraction conditions are: material ratio 1:20, extraction temperature 80 °C, extraction time 60min, ultrasonic power 400W.

[0035] (2) Dyeing process: The best dyeing conditions are: bath ratio 1:40, temperature 80 °C, dyeing time 90min.

[0036] (3) Dyeing process after adding mordant: It is experimentally obtained that ferrous sulfate is used as a mordant, which is more conducive to improving the dyeing performance of Wumei on hemp. Ferrous sulfate mordant and Umei extract of the material-liquid ratio of 1:200, after experimental proof, after the mordant dye is more conducive to the improvement of the performance of hemp fabric, the specific operation is as follows: weigh 2g of hemp into 80ml of Ume extract, the hemp is all wet and sealed with plastic wrap, put into a 50 ° C water bath pot for 90min, after taking out the hemp in the Um...

Abstract

The invention belongs to the field of printing and dyeing, and relates to a process for dyeing China-hemp by using smoked plum, which comprises the following steps: extracting smoked plum pigment from smoked plum; dyeing China-hemp with the dark plum pigment; and carrying out post-mordanting dyeing on the China-hemp to obtain the China-hemp fabric. The fructus mume belongs to a natural dye and has good environmental compatibility and environmental friendliness, meanwhile, the technology can effectively dye the China-hemp fiber, and the dyeing performance of the China-hemp fiber is improved.

Description

Technical field [0001] The present invention belongs to the field of printing and dyeing, mainly relates to a process of dyeing hemp using Ume. Background [0002] Disclosure of the background technical portion of the information is only intended to increase the understanding of the general background of the present invention, and is not necessarily regarded as an acknowledgement or any indication in any form that the information constitutes prior art that has become commonly known to those of ordinary skill in the art. [0003] Hemp fiber is an excellent taking fiber, it fiber fine, high strength, with moisture absorption, breathability, comfort, heat dissipation, mildew, bacteriostatic, radiation resistance and other characteristics, great help to the human body, both have good comfort to take, but also have a certain health care. [0004] Wumei is a natural dye with pharmacological properties, natural and non-toxic, can reduce the harm of dyes to the human body, and has a cert...
