Embodiment 1

[0020] Preparation of apple pomace submerged fermentation aqueous solution: using apple pomace as fermentation substrate, 30 parts by weight of apple pomace, 3 parts by weight of Luo Han Guo pomace, 1 part by weight of rice bran pomace, and 1 part by weight of brewer's grains Add 5000u / g of cellulase and 3000u / g of pectinase, and ferment in a sealed container above 35°C for 20 days. After the fermentation, filter the filtrate through a 200-mesh stainless steel mesh. After fermentation, the residue is filtered through a filter press to form a cake for subsequent composting. Add 5 parts of iron rust and 6 parts of ferrous acetate to the filtrate and soak for 2 days, stir at a low speed of 150 rpm for 30 minutes, and filter the filtrate through a 200-mesh stainless steel mesh.

[0021] The apple pomace is the residue obtained after apple juice is squeezed, and the parts by weight of water are 6-10 parts, the parts by weight of protein are 5-6 parts, and the parts by weight of cru...

Embodiment 2

[0026] Preparation of apple pomace submerged fermentation aqueous solution: using apple pomace as the fermentation substrate, 25 parts by weight of apple pomace, 4 parts by weight of Luo Han Guo pomace, 1 part by weight of rice bran pomace, and 1 part by weight of brewer's grains Add 4000u / g of cellulase and 3000u / g of pectinase, and ferment in a sealed container above 35°C for 20 days. After the fermentation, filter the filtrate through a 200-mesh stainless steel mesh. After fermentation, the residue is filtered through a filter press to form a cake for subsequent composting. In the filtrate, add 5 parts by weight of iron rust and 8 parts of ferrous acetate. After soaking for 2 days, stir at a low speed of 150 rpm for 30 minutes, and filter the filtrate through a 200-mesh stainless steel mesh.

Abstract

The invention relates to a natural dyeing auxiliary agent for dyeing middle and light color systems and a dyeing method of the natural dyeing auxiliary agent. The natural dyeing auxiliary agent consists of, by weight, 90-60 parts of apple pomace liquid fermentation aqueous solution, 0.5-3 parts of B vitamins, 3-0.5 parts of sodium polyaspartate, 0-2 parts of light rare earth EU<3+> or La<3+> and 6.5-34.5 parts of purified water. A composite dyeing mode of one-bath dyeing promotion and after-bath mordant dyeing is adopted. Compared with the prior art, the natural dyeing auxiliary agent has thebeneficial effects that the color systems formed by plant dyeing, such as gray, purple, yellow green and brown, are firm in color fastness after subjected to soaping, dry-wet friction, light resistance and the like, the color fastness is improved by 1-2 levels, and the actual requirement of industrial mass production is met.

Description

technical field [0001] The invention relates to the research and development and application fields of natural dyeing auxiliaries, in particular to natural dyeing auxiliaries for dyeing light gray, purple, purple red, yellow-green and other natural plant dyes and a dyeing method thereof. Background technique [0002] The main by-product of the apple processing industry is apple pomace. In my country, more than 1 million tons of apple pomace are produced every year. The efficient utilization of apple pomace resources is an important way to promote the efficient development of the apple processing industry and reduce ecological environmental pollution. At the same time, my country's Luo Han Guo accounts for more than 90% of the world's output. The pomace produced after the Luo Han Guo is squeezed to produce sweet glycosides is usually discarded as waste or burned as fuel, resulting in a waste of resources. [0003] After research, it is found that acidic substances such as org...
