Embodiment 1

[0026] Embodiment 1: pigment extraction

[0027]After washing the rhizome of madder root, crush it with a Chinese herbal medicine grinder, ferment at 40°C for 24 hours, use a mixed solvent of 90% alcohol and 10% water to extract madder pigment, the solid-liquid ratio is 1:15, heat, and the extraction temperature is 80°C. The evaporated gas was condensed and refluxed with a condenser tube, and extracted twice for 1 hour each time.

Embodiment 2

[0028] Embodiment 2: ecological pretreatment

[0029] 2% baking soda (sodium bicarbonate) (percentage of cloth weight), 2% detergent coconut oil diethanolamide (percentage of cloth weight), 0.5g / L neutral phosphate ester, heating rate 1°C / min, temperature 50°C , time 30min, liquor ratio 1:25.

Embodiment 3

[0030] Embodiment 3: Dyeing process of madder dyestuff - mordant dyeing before cheese

[0031] 1. pigment extraction: with embodiment 1.

[0032] 2. ecological pretreatment: with embodiment 2.

[0033] ③ Dyeing:

[0034] a) Aluminum media treatment: add 1.0g / L neutral phosphoric acid ester to the ecologically pretreated yarn and run it for 10 minutes, then add 5% (cloth weight percentage) aluminum sulfate for mordant dyeing, start to heat up from 30 °C, and the rate is 0.7 °C / min, PH=4.2, heat preservation at 80°C for 30min, bath ratio 1:25.

[0035] b) Rubia dyeing: take 3% (cloth weight percentage) of the obtained pigment bodies for dyeing, first add 2.0g / L neutral phosphate and run for 10 minutes, add 3.0% polyethylene glycol ether (cloth weight percentage) and run for 5 minutes, then add For the dye, the temperature is raised from 20°C at a rate of 0.5°C / min, pH=6.3, kept at 90°C for 60 minutes, and the bath ratio is 1:25.

Abstract

The present invention is madder dye extracting process and its usage in dyeing mercerized wool and mercerized wool fabric. The madder dye extracting process includes the following steps: washing madder root as material, fermentation at 20-50 deg.c for 20í½30 hr, and extracting madder dye through heating at 70-90 deg.c and condensing evaporated gas for 0.5-1.5 hr. The dyeing process includes two steps: the first step of ecological pre-treatment of mercerized wool or mercerized wool fabric in treating liquid comprising sodium bicarbonate, coconut oil biethyl alcohol acrylamine as detergent and neutral organic phosphate in certain proportion at 20-60 deg.c and bath ratio of 1:20-50 for 10-60 min; and the second step of harmless mordant dyeing of the pre-treated mercerized wool or mercerized wool fabric. The present invention has rich dye resource, good dyeing effect and less damage of mercerized wool.

Description

Technical field: [0001] The invention relates to a method for extracting a madder plant dye, and a method for dyeing mercerized wool yarn and mercerized wool fabric by using the madder dye for cheese dyeing, skein dyeing, piece dyeing, and garment dyeing. It belongs to the technical field of wool textiles. Background technique: [0002] With the improvement of people's living standards, people pay more and more attention to the quality of life and living environment. Natural dyes are biodegradable and do not affect the environment. Some natural dyes have health care functions, and most natural dyes are derived from plants, which can be expanded for planting. The industrial application of natural dyes is conducive to increasing the added value of textiles, and has significant economic and social benefits. [0003] The plant madder is used for dyeing and has a long history. It was used for dyeing in the Shang and Zhou dynasties. It was the main dye for dyeing red before the...
