Embodiment 1

[0019] Select lanthanum citrate and add purified water to dissolve it into a 10% aqueous solution of light rare earth lanthanum citrate.

[0020] Mature leaves with high metal elements such as red-skinned rough fruit or red camellia are preferred. Soak camellia tea leaves according to the weight ratio of 1 part of leaves to 3 parts of water, and add 0.5% tartaric acid according to the weight of the solution at the same time, and ferment in a sealed container at 30°C for 3 days, and control the fermentation temperature. When the temperature is higher than 35°C, add pure Cool the water and keep the temperature below 35°C. After a period of time, the fermentation solution no longer heats up, and before the leaves only soften and change color and do not rot, the fermented liquid is filtered out with a 200-mesh stainless steel mesh. After fermentation, the leaves are filtered by a filter press to form a cake, and the cake-shaped fermented leaves can be used for subsequent composti...

Embodiment 2

[0025] Select praseodymium chloride and add pure water to dissolve it into a 10% aqueous solution of light rare earth praseodymium chloride.

[0026] Mature leaves with high metal elements such as red-skinned rough fruit or red camellia are preferred. Soak camellia tea leaves according to the weight ratio of 1 part of leaves to 3 parts of water, and add 0.5% tartaric acid according to the weight of the solution at the same time, and ferment in a sealed container at 30°C for 5 days, and control the fermentation temperature. When the temperature is higher than 35°C, add pure Cool the water and keep the temperature below 35°C. After a period of time, the fermentation solution no longer heats up, and before the leaves only soften and change color and do not rot, the fermented liquid is filtered out with a 200-mesh stainless steel mesh. After fermentation, the leaves are filtered by a filter press to form a cake, and the cake-shaped fermented leaves can be used for subsequent comp...

Embodiment 3

[0031] Select neodymium chloride, add pure water to dissolve into 10% light rare earth neodymium chloride aqueous solution.

[0032] Mature leaves with high metal elements such as red-skinned rough fruit or red camellia are preferred. Soak camellia tea leaves according to the weight ratio of 1 part of leaves to 3 parts of water, and at the same time add 1% tartaric acid according to the weight of the solution, and ferment in a sealed container at 30°C for 4 days, and control the fermentation temperature. When the temperature is higher than 35°C, add pure Cool the water and keep the temperature below 35°C. After a period of time, the fermentation solution no longer heats up, and before the leaves only soften and change color and do not rot, the fermented liquid is filtered out with a 200-mesh stainless steel mesh. After fermentation, the leaves are filtered by a filter press to form a cake, and the cake-shaped fermented leaves can be used for subsequent composting. The press-...

Abstract

The invention discloses a natural dyeing assistant for sorghum husk pigment plant dyeing. The natural dyeing assistant is composed of the following raw materials in parts by weight of 0.5-5 parts of B vitamins, 10-50 parts of a light rare earth aqueous solution, 1-3 parts of tartaric acid, 5-1 part of sodium polyaspartate, 60-5 parts of a camellia leaf fermentation solution, 1-0.5 part of Turkey red oil and 22.5-35.5 parts of purified water. The invention relates to a dyeing method of the natural dyeing assistant for sorghum husk pigment plant dyeing. A composite dyeing mode of one-bath accelerating and post-bath mordant dyeing with sorghum husk pigment plant dye is adopted. Compared with the prior art, the natural dyeing assistant has the beneficial effects that after a fabric is dyed by red sorghum pigment, the dyeing efficiency is improved, the soaping fastness can reach 3.5 grade or above, the dry and wet rubbing fastness can reach 3 grade or above, the color fastness to light can reach 4 grade or above, and the sorghum husk pigment plant dyeing meets the actual requirements of industrial mass production.

Description

technical field [0001] The invention relates to the field of research and development and application of natural dyeing auxiliaries, in particular to the natural dyeing auxiliaries used in the vegetable dyeing process of sorghum husk pigments on wool fibers, yarns, fabrics and garments and the dyeing method thereof. Background technique [0002] With the development and advancement of plant dye dyeing technology, more and more plant pigments are used as plant dyes in the textile printing and dyeing industry. Among them, sorghum husk pigment is extracted from sorghum husk. Because sorghum husk has a wide range of sources, it is a by-product of grain, brewing, feed processing and other industries. Therefore, it is low in price, high in pigment content, and easy to extract. Therefore, it is listed as the first choice for plant dyes. [0003] However, sorghum husk pigments have low color uptake in the printing and dyeing industry, and are far from the color fastness of petrochem...
