Embodiment 1

[0017] The extraction steps of the red sandalwood dye in this example are as follows: take the waste materials of red sandalwood, etc., dry them in an oven at 60°C for 2 hours, pulverize them to 100 meshes by low-temperature ultra-micro-mechanical, and use the volume percentage concentration of the crushed red sandalwood to 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 Daguo red sandalwood dye on fabrics such as nylon and wool are as follows:

[0019] (1) preparation of dye liquor: the red sandalwood dye, alum, leveling agent and water prepared in claim 1 are formulated with the following mass percentages, 6 parts of said red sandalwood dye, 3 parts of sa...

Embodiment 2

[0023] The extraction procedure of the dyestuff in this example is as follows: take the waste material of red sandalwood, etc., dry it in an oven at 60°C for 2 hours, pulverize it to 50 mesh by low-temperature ultra-micro-mechanical, and use a volume percentage concentration of 75% of the crushed red sandalwood. 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 red sandalwood dye.

[0024] The dyeing process steps of the large-fruit red sandalwood dye on fabrics such as nylon and wool as claimed in claim 1 are:

[0025] (1) preparation of dye liquor: the red sandalwood dye, alum, leveling agent and water prepared in claim 1 are formulat...

Embodiment 3

[0029] The extraction procedure of the dyestuff in this example is as follows: take the waste material of red sandalwood, etc., dry it in an oven at 70°C for 2 hours, pulverize it to 50 mesh by low-temperature ultra-micro-mechanical, and use PH=7, volume percentage to grind the crushed red sandalwood. The concentration is 75% ethanol plant ash aqueous solution as the extractant, the mass ratio of solid to liquid is 1:40, and the temperature is 60 ° C. After ultrasonic extraction for 2 hours, vacuum filtration, the filter residue is extracted again by the same method, and the two filtrates are combined. Rotary evaporator vacuum distillation, concentration, natural dyes.

[0030] The dyeing process steps of the large-fruit red sandalwood dye on fabrics such as nylon and wool as claimed in claim 1 are:

[0031] (1) preparation of dye liquor: the red sandalwood dye, alum, leveling agent and water prepared in claim 1 are formulated with the following mass percentages, 5 parts of sa...

Abstract

The invention relates to the field of light chemical industry, and aims to provide a large-fruit red sandalwood dye and a fabric dyeing method. The extraction method of the large fruit red sandalwood dye comprises the steps of: taking the large fruit red sandalwood waste material, mechanically pulverizing it, placing it in an aqueous ethanol solution, using plant ash to adjust the pH value of the solution, ultrasonic extraction and suction filtration of the extract, and vacuum distillation and concentration Can obtain big fruit red sandalwood dyestuff; This dyeing method comprises the steps: the big fruit red sandalwood dyeing solution is configured with the gained big fruit red sandalwood dye with alum, leveling agent, deionized water etc. with proper bath ratio, temperature, Under the condition of pH value, immerse the fabric into the dyeing solution of red sandalwood and dye it in a water bath, take out the fabric, wash it in cold water and dry it. 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 a method for extracting mahogany dye and a fabric dyeing method thereof, in particular to a redwood dye and a fabric dyeing method. technical background [0002] The chemical components of the inclusions in red sandalwood mainly include eucalyptol, nerolidol, pterwood, benzopyranone flavonoid pigments, etc. [Liu Xiaojin, Hainan Jianfengling large fruit sandalwood heartwood ratio and composition of essential oils, 2017 ], with stable and long-lasting fragrance, anti-inflammatory, antiseptic and other pharmacological effects [Lin Jinguo, antibacterial effect of different solvent extracts of 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 ...
