preparation example 1

[0031] After the prepared mugwort leaves are washed and dried, the walls are broken with a wall breaking machine to obtain a dark green paste liquid, which releases the unique aroma of mugwort. Take 100g of pasty liquid each time, use ethanol as solvent to dissolve according to the ratio in the table, and then filter with suction to get the filtrate. The dyes were prepared according to the mass ratio of pasty liquid and ethanol solvent as 1:1, 1:2, 1:3, and 1:4 respectively.

[0032] Take an equal amount (100g) of dye, and under the same conditions, directly dye an equal amount of cotton fabric (2.5g) for 50 minutes at a temperature of 65°C and a bath ratio of 1::30. The results are shown in the table below:

[0033]

[0034] Combining the state and color of the dyeing liquor after filtration and the effect of direct dyeing of the fabric, further through the determination of parameters such as dyeing depth, dry and wet rubbing fastness, staining, and discoloration, the mass...

Embodiment

[0036] Post-mordant staining:

[0037] At room temperature, take mugwort leaf pigment to prepare 300ml of dye solution, the mass concentration of mugwort leaf pigment is 33%, heat up to 80°C (3°C / min), add dyeing accelerator salt, and after it dissolves evenly, add 10g of pure cotton bleached twill fabric, The bath ratio is 1:30. After the dyeing is completed, add mordant, and then mordant for 15 minutes. After the mordant is completed, fix the color salt, keep it warm for 15 minutes, wash it with water, and dry it.

[0038] Direct staining method:

[0039] At room temperature, take mugwort leaf pigment and make dye solution 300ml, the mass concentration of mugwort leaf pigment is 33%, add dyeing accelerator salt, heat up to 65°C (2°C / min), add mordant and 10g of pure cotton bleached twill fabric, liquor ratio The ratio is 1:30. After the dyeing is completed, add color-fixing salt and keep warm for 15 minutes to fix the color. After dyeing, wash with water and dry.

Abstract

The invention provides application of folium artemisiae argyi pigment dye to a cotton fiber post-mordant dyeing process. Cotton fiber is dyed with the dye through a post-mordant dyeing method, so folium artemisiae argyi pigment can serve as plant dye of the cotton fiber; moreover, a dyeing process which applies the folium artemisiae argyi pigment dye to cotton fiber dyeing and has an industrialized application value is provided; and by the post-mordant dyeing method of pure cotton fiber, the color depth K / S value of cotton fabric reaches 4.215, unlubricated friction reaches level 4 to 5, wet friction reaches level 4, color change reaches level 4, staining (cotton) reaches level 4 to 5 and hand feeling reaches level 4, the actual industrial production requirements are met, and the technological gap of folium artemisiae argyi pigment plant dye in the prior art is filled.

Description

technical field [0001] The invention relates to a dyeing method of mugwort leaf pigment dye, in particular to the application of mugwort leaf pigment dye in post-mordant dyeing process of cotton fiber. Background technique [0002] There are 3000-5000 substances that can be used for dyeing in nature, among which plant dyes have a relatively complete color spectrum, and can obtain purple, red, yellow, green, brown, blue, black, etc., which can be used for dyeing protein fibers such as silk and wool . Plant dyes can be classified into indoles, flavonoids, quinones, tannins, carotenoids, chlorophyll and alkaloids according to their chemical composition. It can be seen that due to the relatively complex structure of natural plant dyes, different plant dyes have different dyeing mechanisms, and the dyeing mechanisms of many dyes need to be explored, and plant dyes have low dye content, low extraction rate, complex dyeing process, and low Problems such as poor reproducibility, l...
