Embodiment 1

[0017] The extraction steps of the sandalwood red sandalwood dye in this example are as follows: take sandalwood red sandalwood waste materials, etc., dry them in an oven at 60°C for 2 hours, grind them to 100 mesh with low-temperature ultra-micro-mechanical, and use volume percentage concentration of the crushed sandalwood red sandalwood Extract with 75% ethanol solution, the mass ratio of solid to liquid is 1:30, adjust PH=8 with plant ash, ultrasonically extract at 60°C for 2 hours, vacuum filter, extract the filter residue again with the same method, and combine the two filtrates , concentrated by vacuum distillation with a rotary evaporator to obtain natural dyes.

[0018] The dyeing process steps of present embodiment sandalwood red sandalwood dye on fabrics such as nylon and wool are:

[0019] (1) prepare dye liquor: the sandalwood red sandalwood dye, alum, leveling agent and water prepared in claim 1 are formulated with the following mass percentages, 6 parts of descri...

Embodiment 2

[0023] The extraction steps of the dye in this example are as follows: take sandalwood red sandalwood waste materials, etc., dry them in an oven at 60°C for 2 hours, crush them to 50 mesh with low-temperature ultra-micro-mechanical, and use the volume percentage concentration of the crushed sandalwood red sandalwood to be 75%. The ethanol aqueous solution extraction, the mass ratio of solid to liquid is 1:30, the pH value of the solution is adjusted to about 8 with plant ash, ultrasonic extraction at 60°C for 2 hours, vacuum filtration, the filter residue is extracted again by the same method, and the two filtrates are combined , concentrated by rotary evaporator under reduced pressure distillation to obtain natural sandalwood red sandalwood dye.

Abstract

The invention relates to the field of light chemical industry and aims to provide a sandalwood rosewood dye and a fabric dyeing method. The extraction method of the sandalwood red sandalwood dye includes the following steps: take the sandalwood red sandalwood waste material, put it in the ethanol aqueous solution after mechanical crushing, adjust the pH value of the solution with plant ash, ultrasonic extraction and suction filtration of the extract, vacuum distillation and concentration Can obtain sandalwood red sandalwood dye; This dyeing method comprises the steps: the obtained sandalwood red sandalwood dye and alum, leveling agent, deionized water etc. are configured into sandalwood red sandalwood dyeing solution with a certain ratio, with appropriate bath ratio, temperature, Under the condition of PH value, the fabric is immersed in the sandalwood and red sandalwood dye solution for water bath dyeing, and the fabric is taken out to be washed in cold water and dried. The invention has the advantages of simple extraction process, good extraction effect, environmental protection and pollution-free extraction and dyeing process, high color fastness of dyed fabrics, long-lasting fragrance, safe to wear, certain antibacterial, anti-inflammatory and medicinal health effects, and has a very broad market prospect.

Description

technical field [0001] The invention relates to an extraction method of mahogany dye and a fabric dyeing method thereof, in particular to a sandalwood rosewood dye and a fabric dyeing method. technical background [0002] The chemical components of sandalwood and red sandalwood mainly include eucalyptol, nerolidol, pterwood, benzopyranone flavonoids, etc. ], with stable and long-lasting fragrance, anti-inflammatory, antiseptic and other pharmacological effects [Lin Jinguo, antibacterial effect of different solvent extracts of sandalwood and red sandalwood heartwood, 2015]. [0003] Dayong Town is known as "China's mahogany furniture production professional town", "China's thousand strong town", "China's denim clothing town" and other titles, but the current international management of tropical forests, especially mahogany resources, is showing a trend of strict control. Coupled with the blowout development of mahogany furniture market in Asia, there is an increasing shortag...
