Problems solved by technology

The raccoon fur fiber itself is taupe. Take the development of light-colored and bright products as an example. The raccoon fur fiber is decolorized and bleached. In the subsequent dyeing process, the fiber has been partially damaged due to decolorization, and the animal protein fiber is generally damaged. Higher dyeing temperature will not only increase the cost of dyeing, but also cause serious damage to the fiber, making the texture of the fiber worse and the strength lower, which is not conducive to the subsequent spinning process, and will also affect the wearability of the product. Therefore, it is necessary to look for research on environmental protection, safety and A dyeing method with less fiber damage is necessary

Embodiment 1

[0014] A method for dyeing decolorized raccoon fur. At room temperature, the decolorized raccoon fur is soaked in natural plant dyes, the temperature is raised to 70°C, and after soaking for 40 minutes, a mordant is added. The ratio of the amount of the natural plant dye to the mordant is 1:2. The mordant is one or more of rare earths or citric acid. After keeping at a constant temperature of 70°C for 30 minutes, the decolorized raccoon fur is taken out, rinsed with water and dried to obtain dyed raccoon fur.

Embodiment 2

[0016] A method for dyeing decolorized raccoon fur. At room temperature, the decolorized raccoon fur is soaked in natural plant dyes, heated up to 80°C, soaked for 30 minutes, and then added with a mordant. The ratio of the amount of the natural plant dye to the mordant is 2:3. The mordant is one or more of rare earths or citric acid. After keeping at a constant temperature of 80°C for 20 minutes, the decolorized raccoon fur is taken out, rinsed with water and dried to obtain dyed raccoon fur.

Embodiment 3

[0018] A method for dyeing decolorized raccoon fur. At room temperature, the decolorized raccoon fur is soaked in natural plant dyes, heated to 75°C, soaked for 35 minutes, and then added with a mordant. The ratio of the amount of the natural plant dye to the mordant is 1.5:2.5. The mordant is one or more of rare earth or citric acid. After keeping at a constant temperature of 75° C. for 25 minutes, the decolorized raccoon fur is taken out, rinsed with water and dried to obtain dyed raccoon fur.

[0019] There are many ways to extract natural plant dyes:

[0020] A method for extracting natural plant dyes is as follows: boil the natural plant dyes in boiling water with a liquor ratio of 1:10 to 1:20 for 30 to 40 minutes, after filtering, add water to the filter residue and continue to boil and filter, and mix the filtrate obtained from the two filtrations. That is, the natural vegetable dye is obtained.

[0021] Another method for extracting natural plant dyes is as follows: ...

Abstract

The invention relates to a decolored raccoon hair dyeing method. The decolored raccoon hair dyeing method comprises the steps that decolored raccoon hair is soaked in a natural plant dye at normal temperature, heating is performed to reach 70-80 DEG C, soaking is performed for 30-40 minutes, then a mordant is added, the constant temperature of 70-80 DEG C is kept for 20-30 minutes, then the decolored raccoon hair is taken out and flushed with water, and then drying is performed to obtain dyed raccoon hair. The decolored raccoon hair dyeing method is healthy and environmentally friendly, the used dye is a natural plant dye, bright color and luster, good color fastness and other properties of the dyed decolored raccoon hair can be improved, and the dyed decolored raccoon hair is non-toxic, harmless, natural and non-irritant.

Description

【Technical field】 [0001] The invention belongs to the technical field of dyeing production, and in particular relates to a dyeing method for decolorized raccoon fur. 【Background technique】 [0002] Raccoon fur is a kind of special animal protein fiber. The fiber is slender, light, warm and smooth, with high natural curl and good warmth retention. Raccoon fur is a new raw material for wool spinning and has great potential in product development. The application prospect is broad. [0003] In today's society, with the rapid development of science and technology and the continuous enrichment of material life, people's requirements for clothing, food, housing and transportation are also constantly increasing. Not only do they require comfort and beauty, but they also pay more attention to their environmental protection and health functions. On the one hand, fabrics dyed with synthetic dyes can irritate the skin, and on the other hand, they can also pollute the environment durin...
