Embodiment 1

[0020] (1) Preparation of walnut green husk extract: Weigh 50 g of walnut green husk powder and place in a container, add 1000ml of methanol, extract in a water bath at 40°C for 12 hours to obtain an extract, and the filtrate obtained by suction filtration is walnut green husk extract.

[0021] (2), dyeing: 2.0g wool and 4% FeSO by weight of wool 4 .7H 2 Put the O mordant in 40ml distilled water, take it out after mordant at 50°C for 60min;

[0022] (3) Put the mordant wool obtained in step (2) into a dyeing bath made of 20ml of walnut green husk extract prepared in step (1) and 6% pyrogallic acid by weight of wool, and adjust the pH of the dyeing bath to 4, then warm up to 50°C, and dye for 10 minutes under stirring.

[0023] (4) Take out the wool, rinse it with cold water, and dry it.

Embodiment 2

[0025] (1) Weigh 60g of walnut green husk powder, add 600ml of distilled water, extract in a water bath at 65°C for 18h, and filter with suction to obtain the filtrate.

[0026] (2), dyeing: 2.0g wool and 8% FeSO by weight of wool 4 .7H 2 Put the O mordant in 40ml distilled water, take it out after mordant at 40°C for 40min;

[0027] (3) Put the mordant wool obtained in step (2) into a dyeing bath made of 30ml of walnut green husk extract prepared in step (1) and pyrogallic acid of 4% by weight of wool, and adjust the pH of the dyeing bath It is 5.5, and then the temperature is raised to 70°C, and dyed for 60 minutes under stirring.

[0028] (4) Take out the wool, rinse it with cold water, and dry it.

Abstract

The invention provides a method for applying walnut peel extracting solution in black wool dyeing. Walnut peel powder is taken and placed into a container, solvent is added for extraction, and suction filtering is carried out to obtain filtrate; and then wool is dyed by adopting a pre-mordanting method, thus black wool is obtained. According to the invention, the walnut peel extracting solution is adopted, ferrite is taken as a mordanting agent to dye the wool, and black of the dyed wool is pure. Meanwhile, the mordanting agent exists, colour fastness and dyeing rate are greatly improved, waste of resource is effectively reduced, and the black wool has non-toxic pollution-free environmental protection effects.

Description

technical field [0001] The invention relates to a method for dyeing wool with plant extracts, in particular to a method for dyeing black wool with walnut green bark aqueous extract. Background technique [0002] Chemical dyes are used in the dyeing of various textile fibers, providing humans with colorful fabrics and clothing, but chemical dyes are mainly made of primary chemical substances fractionated from coal tar or petroleum derivatives, which are processed under high temperature and high pressure. It is prepared by a variety of chemical reactions, and many carcinogens will be produced during its production. These toxic or environmentally harmful substances will inevitably be dumped into rivers, ponds or volatilized into the air during production and use, polluting the environment, and some of them will cause skin diseases and harm the human body. Therefore, on July 15, 1994, the German government promulgated for the first time in the form of legislation a decree prohi...
