Example Embodiment

[0012] Example 1, dyeing wool with polygonum extract dyestuffs;

[0013] (1) Microwave extraction method of plants: leaves of plant tissue, add 2-3 times of water by weight, heat and boil for 3-5 minutes, place in a beater after cooling, and beat to obtain pulp; Add 80-95% ethanol to 4-6 times, shake well for 5-10 minutes; place it in a microwave reactor for extraction; control the extraction temperature to 40-60°C, adjust the microwave frequency to 2200-2500MHZ, and the extraction power to 500- Extraction at 800W for 30min-40min, take out suction filtration to obtain the leaching solution; extract the filter residue once again, combine the two leaching solutions, collect all the solutions, and concentrate by rotary evaporation under reduced pressure to obtain dye products.

[0014] (2) a dyeing method of a natural dye: take one or more of the dyes obtained above, add water to prepare a dye, the dye concentration is 3-6% (o.w.f), and the added NaCl concentration is 1-2.5% (o.w...

Example Embodiment

[0015] Example 2, dyeing wool with polygonum extract dyestuffs;

[0016] (1) dye extraction method is identical with Example 1;

[0017] (2) dyeing method: a kind of dyeing method of natural dyes: take one or more of the dyes obtained above, add water to prepare dyes, the dye concentration is 3-6% (o.w.f), and the concentration of adding NaCl is 1-2.5% ( o.w.f); the bath ratio is 1:10-30, under the condition of sound waves with a frequency of 30KHz, the dye liquor is treated for 15-30 minutes, and the temperature is gradually raised to 48-80°C; The hemp fiber is dyed in the dye solution; firstly, a combination of 22KHz, 28KHz, 50KHz ultrasonic waves is used, and the ultrasonic power intensity is 0.3-1.0W / cm 2 After dyeing, use a combination of 22KHz, 28KHz, 40KHz and 55KHz ultrasonic waves, keep at 40°C for 10-25 minutes to do soaping once, and wash with warm water at 30°C for two times. times, the ultrasonic power intensity is 0.5-1.0W / cm 2 .

Example Embodiment

[0018] Example 3, dyeing wool with polygonum extract dyestuffs;

[0019] (1) dye extraction method is identical with Example 1;

[0020] (2) dyeing method: a kind of dyeing method of natural dyes: take one or more of the dyes obtained above, add water to prepare dyes, the dye concentration is 3-6% (o.w.f), and the concentration of adding NaCl is 1-2.5% ( o.w.f); the bath ratio is 1:10-30, under the condition of sound waves with a frequency of 30KHz, the dye liquor is treated for 15-30 minutes, and the temperature is gradually raised to 48-80°C; The hemp fiber is dyed in the dye solution; firstly, a combination of 22KHz, 28KHz, 50KHz ultrasonic waves is used, and the ultrasonic power intensity is 0.3-1.0W / cm 2 After dyeing, use a combination of 22KHz, 28KHz, 40KHz and 55KHz ultrasonic waves, keep at 40°C for 10-25 minutes to do soaping once, and wash with warm water at 30°C for two times. times, the ultrasonic power intensity is 0.5-1.0W / cm 2 .

Abstract

The invention relates to the technical field of textile printing and dyeing, and concretely relates to a natural textile dye and a sound wave dyeing application thereof. Whole plants of Polygonum orientale, Dicliptera chinensis, Kochia scop aria, Siberia Cocklebur, Artemisia argyi and garden sorrel undergo microwave extraction, and one or more of above obtained extracts is/are adopted as a dye to dye a processed economic fabric. The dye is prepared through extracting pigments from plants, so the dye contains no chemical components, and is green and environmentally friendly; and the dye is used in low-temperature sound wave dyeing of textiles, and the textiles dyed with the dye have the advantages of uniform coloring and antibiosis function.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a natural textile dye and the application of sonic dyeing. Background technique [0002] Entering the 21st century, the development of science and technology pays more attention to environmental protection and ecological balance, and people doubly protect and cherish the earth home. With the improvement of people's living standards, the quality requirements of textiles are getting higher and higher, and the voice of "returning to nature" is becoming stronger and stronger. They pursue comfort, nature and health care in clothing, so the added value of textiles is increased, and products are diversified. Functionalization and gentrification are the development direction of textile processing. [0003] Synthetic dyes have promoted the development of the textile industry, but the wastewater discharged during the printing and dyeing process is difficult to biodegra...
