Problems solved by technology

During the oxidation-reduction process, the wool is seriously damaged. As a result, the strength of the wool fiber is reduced, the color is yellowed, the spinnability is greatly reduced, and the quality of the yarn is reduced. Even put a heavy burden on Shubu

Embodiment 1

[0018] Such as figure 1 As shown, the collected madder is fully cleaned to remove impurities, dried naturally or at low temperature, and then pulverized in a pulverizer to obtain madder plant powder residue, and the mixed solution of ethanol is poured into the madder plant powder residue, and ultrasonic treatment is used , the ultrasonic power is 250W, the extraction temperature is 80°C, and the extraction time is 60min, to obtain the Rubia plant dye extract. The extract was subjected to high-speed centrifugation at a centrifugal speed of 8500 r / min and a centrifugation time of 20 minutes. After removing impurities, vacuum concentration and drying were carried out at a vacuum pressure of 0.2 MPa and a drying temperature of 60° C. for 45 minutes to obtain Rubia plant dye powder.

Embodiment 2

[0022] Fully wash the collected madder to remove impurities, dry it naturally or at low temperature, and then pulverize it in a pulverizer to obtain madder plant powder residue, pour the mixed solution of ethanol into the madder plant powder residue, and use ultrasonic treatment, ultrasonic power 250W, extraction temperature 80°C, extraction time 60min, to obtain Rubia plant dye extract. The extract was subjected to high-speed centrifugation at a centrifugal speed of 8500 r / min and a centrifugation time of 20 minutes. After removing impurities, vacuum concentration and drying were carried out at a vacuum pressure of 0.2 MPa and a drying temperature of 60° C. for 45 minutes to obtain Rubia plant dye powder.

[0023] Weigh a certain amount of 70S Australian Merino mercerized wool strips (fineness 19.5 microns), add alum to the dyeing vat for mordant dyeing, the amount of alum is 8%, the heating rate is 1°C / min, the mordant dyeing temperature is 80°C, and the mordant dyeing time i...

Abstract

The invention discloses a technology method for wool tops dyed with a madder plant dye. The method particularly comprises the following steps that collected madder is fully cleaned, impurities are removed, the madder is pulverized in a pulverizer after being naturally aired or dried at low temperature, and madder plant powder dregs are obtained; an ethanol solution is poured into the madder plant powder dregs, and a madder plant dye extracting solution is obtained by adopting ultrasonic treatment; high-speed centrifugation is performed on the extracting solution, and after impurities are removed, vacuum concentrating and drying are performed to obtain madder plant dye powder; a certain quantity of the wool tops are weighed, alums are firstly added in a dye vat for mordanting, the madder plant dye powder is dissolved in soft water, the mixture is added in the dye vat, and after the pH value is regulated with acetic acid, the temperature is increased, and dyeing starts to be performed; soaping is performed after dyeing is finished, the wool tops are washed with clear water and dried after soaping is finished, and the wool top dyed with the madder plant dye are obtained.

Description

technical field [0001] The patent of the invention belongs to the technical field of wool fiber dyeing, and in particular relates to a wool fiber strip dyeing process using madder plant dye. Background technique [0002] Acid mordant dyes have been used in the wool spinning industry for many years. The hazards of acid mordant dyes include: the pollution of hexavalent chromium ions in dyeing wastewater to the environment; the second is the existence of extractable chromium ions on the dyed fibers, which is seriously harmful to the human body; the third is to prevent the discarding of waste materials after dyeing pollution of the environment. When used for wool dyeing, due to hexavalent chromium ions, it must be reduced to trivalent in order to complex with dyes. During the oxidation-reduction process, the wool is seriously damaged. As a result, the strength of the wool fiber is reduced, the color is yellowed, the spinnability is greatly reduced, and the quality of the yar...
