Embodiment 1

[0023] Embodiment 1: ecological pretreatment

[0024] Treatment conditions: 2.5% baking soda (sodium bicarbonate) (percentage of cloth weight), 2.5% detergent coconut oil diethanolamide (percentage of cloth weight), 0.5g / L neutral phosphate, heating rate 1°C / min, The temperature is 50°C, the time is 30 minutes, and the bath ratio is 1:25.

Embodiment 2

[0025] Embodiment 2: dyeing process of yellow chrysanthemum dyestuff - mordant dyeing before bobbin yarn

[0026] ①Pigment extraction: take crushed yellow chrysanthemum flowers and add 40 times soft water to boil for 3 hours, filter through a 240-mesh sieve to obtain the original solution, extract 3 times according to this method, mix the obtained three times of the original solution, and then spray dry to obtain the pigment body.

[0027] 2. ecological pretreatment: with embodiment 1.

[0028] ③ Dyeing:

[0029] a) Aluminum media treatment: Add 1.5g / L neutral phosphoric acid ester to the ecologically pretreated yarn and run it for 10 minutes, then add 7.5% (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 45min, bath ratio 1:25.

[0030]b) Yellow chrysanthemum dyeing: take 5% (cloth weight percentage) of the obtained pigment bodies for dyeing, first add 3.0g / L neutral ...

Embodiment 3

[0031] Embodiment 3: dyeing process of yellow chrysanthemum dyestuff-mordant dyeing before cloth

[0032] 1. pigment extraction: with the pigment extraction of embodiment 2.

[0033] 2. ecological pretreatment: with embodiment 1.

[0034] ③ Dyeing:

[0035] a) Aluminum media treatment: Add 0.75g / L neutral phosphoric acid ester to the ecologically pretreated cloth and run it for 10 minutes, then add 8% (cloth weight percentage) of aluminum sulfate for mordant dyeing, start to heat up from 30°C, and the rate is 1.0°C / min, PH=4.1, 80°C for 30min, bath ratio 1:30.

Abstract

The present invention relates to a method of dyeing mercerized wool or mercerized wool fabrics with yellow chrysanthemum paint, which is taken as the paint, and the dyeing method is divided into two steps including ecological pretreatment and subsequent innocuous mordant dyeing: the first step, treatment conditions: baking soda of 1-3 percent of cloth weight, 1-5 percent coconut oil diethanol amide as detergent of 1-5 percent of cloth weight, 0.2-1.0g/L neutral phosphate, temperature 20-60 DEG C, duration 10-60min, bathing ratio 1 to 20-50; the second step, mordant dyeing: the mercerized wool or mercerized wool fabrics with ecological pretreatment is treated with mordant front dyeing, single bathing or post dyeing. The yellow chrysanthemum resources are rich, easy for expanding plantation, with sound dyeing and less damage to mercerized wool during dyeing.

Description

technical field [0001] The invention relates to a method for dyeing mercerized wool or mercerized wool fabric with chrysanthemum dye, in particular to a method for dyeing mercerized wool or mercerized wool fabric with chrysanthemum dye using bobbin dyeing, piece dyeing, skein dyeing, and garment dyeing. It belongs to the technical field of wool textile. 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. All developed countries pay close attention to the problems of textile factory sewage and textiles containing pathogenic substances. Many European countries have proposed to implement various "environmental labeling systems" for textiles to determine the specifications of green textiles. The toxic pollution sources of the wool textile industry come from certain synthetic dyes and certain finishing agents, which not only seriously pollute the environment, but also ...
