example 1

[0012] Example 1, dyeing wool with Polygonum rubrum extract dyestuff;

[0013] (1) The microwave extraction method of plant: the leaf of plant tissue, adds 2-3 times of water by weight and boils 3-5 minute, is placed in the beating machine after cooling and beating, obtains juice; Add 80-95% ethanol to 4-6 times, shake well for 5-10 minutes; place 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- Extract at 800W for 30min-40min, take out and filter with suction to obtain the leach solution; extract the filter residue once more, combine the two extracts, collect all the solutions, and concentrate by rotary evaporation under reduced pressure to obtain the dye product.

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

example 2

[0015] Example 2, dyeing wool with the dye extracted from Polygonum rubrum;

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

[0017] (2) dyeing method: a dyeing method of natural dyes: get one or more of the dyes prepared above, add water to prepare dyes, dye concentration is 3-6% (o.w.f), and adding NaCl concentration is 1-2.5% ( o.w.f); 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 dyeing solution; first use a combination of 22KHz, 28KHz, and 50KHz ultrasonic waves, and the ultrasonic power intensity is 0.3-1.0W / cm 2 , keep warm at 40-55°C for 40-60 minutes for dyeing processing; after dyeing, use a combination of 22KHz, 28KHz, 40KHz and 55KHz ultrasonic waves, keep warm at 40°C for 10-25 minutes for soaping once, and wash twice with warm water at 30°C times, the ultrasonic power intensity is 0...

example 3

[0018] Example 3, dyeing wool with the dye extracted from Polygonum rubrum;

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

[0020] (2) dyeing method: a dyeing method of natural dyes: get one or more of the dyes prepared above, add water to prepare dyes, dye concentration is 3-6% (o.w.f), and adding NaCl concentration is 1-2.5% ( o.w.f); 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 dyeing solution; first use a combination of 22KHz, 28KHz, and 50KHz ultrasonic waves, and the ultrasonic power intensity is 0.3-1.0W / cm 2 , keep warm at 40-55°C for 40-60 minutes for dyeing processing; after dyeing, use a combination of 22KHz, 28KHz, 40KHz and 55KHz ultrasonic waves, keep warm at 40°C for 10-25 minutes for soaping once, and wash twice with warm water at 30°C times, the ultrasonic power intensity is 0...

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...
