Embodiment 1

[0022] In parts by weight, 40 parts of tender maple leaves are crushed, soaked in 60 parts of ethanol for 24 hours, and the filter residue is filtered with gauze to obtain the black dyeing agent. Soak the wool in 50 parts of black dyeing agent and heat to 50°C-60°C, add 20 parts of ferrous sulfate, 20 parts of ferric chloride, and 10 parts of alum after 30 minutes and keep at 50°C-60°C, take it out after 30 minutes, and place it in a cool and ventilated place Do not expose to the sun, let it dry naturally and then wash it with water to get natural black wool.

Embodiment 2

[0024] In parts by weight, crush 40 parts of Commelina chinensis, soak in 60 parts of ethanol for 24 hours, and filter the filter residue with gauze to obtain the blue dye. Soak the wool in 50 parts of blue dyeing agent and heat to 50°C-60°C. After 30 minutes, add 10 parts of alum and 40 parts of aluminum sulfate to keep at 50°C-60°C. After 30 minutes, take it out and place it in a cool and ventilated place. Do not expose it to the sun. Let it dry naturally and then wash it with clean water to get blue wool.

Embodiment 3

[0026] In parts by weight, 40 parts of loofah leaves are crushed, soaked in 60 parts of ethanol for 24 hours, and the filter residue is filtered with gauze to obtain a yellow-green dye. Soak wool in 50 parts of yellow-green dyeing agent and heat to 50°C-60°C, add 40 parts of copper sulfate after 30 minutes, keep 10 parts of alum at 50°C-60°C, take it out after 30 minutes, put it in a cool and ventilated place, do not expose to the sun, Naturally air-dried and then washed with water to obtain yellow-green wool.

Abstract

The invention discloses a low-temperature wool staining method. The method includes the steps that wool is soaked in a plant staining agent to be heated to 50 DEG C to 60 DEG C, mordant is added 25 to 35 min later, then the wool is taken out after being kept at the temperature of 50 DEG C to 60 DEG C for 25 min to 35 min, the wool is cleaned up with clean water after being naturally air-dried, and the stained wool can be obtained. The low-temperature wool staining method is safe and environmentally friendly, the used staining agent is a plant staining agent which is natural and free of toxin, the stained wool is natural in color and luster, bright, high in color fastness and the like, the comprehensive performance of the stained wool is improved, and the stained wool is free of pungent odor, allergy, and heavy metal.

Description

technical field [0001] The invention belongs to the technical field of dyeing production, and in particular relates to a wool low-temperature dyeing method. Background technique [0002] Wool is a natural protein fiber, which is widely used in high-grade textile fabrics due to its excellent hygroscopicity, resilience and wearing comfort. However, wool fiber has a complex macro- and micro-structure, and its fiber surface covers There is a scale layer. Because the texture of the scale layer is hard, dense and hydrophobic, it is extremely unfavorable to the adsorption and dyeing of dye molecules, and it also hinders the diffusion of dyes into the fiber. Therefore, wool is generally dyed at high temperature at 95-100 °C. [0003] With the improvement of people's living standards, people's allergies are becoming more and more serious. Synthetic dyes on clothes, trousers, and socks that are in direct contact with the skin are one of the causes of allergies. Similarly, the synthet...
