Embodiment 1

[0031] Select pure wool fabric for dyeing, specifically:

[0032] Take an appropriate amount of peony flower pigment (paste or liquid), dissolve it in water, prepare a solution with a concentration of 60g / L peony flower pigment, then add glacial acetic acid to adjust the pH value of the dyeing solution to 2, put the wet woolen fabric into In the dyeing solution, the dyeing bath ratio is 28:1, the dyeing temperature is 95° C., and the dyeing time is 45 minutes. After washing with water, soap wash at 90°C for 10 minutes, then wash with water and dry to obtain a woolen fabric with certain vividness and color fastness. The dyeing process curve is attached figure 1 shown.

Embodiment 2

[0034] Select pure wool fabric for dyeing, specifically:

[0035] Take an appropriate amount of peony flower yellow pigment (powder), add water to dissolve, prepare a solution with a concentration of 5g / L peony flower pigment, then add glacial acetic acid to adjust the pH value of the dyeing solution to 3, put the wet woolen fabric into the dyeing solution Among them, the dyeing bath ratio is 30:1, the dyeing temperature is 80°C, and the dyeing time is 90 minutes. After washing with water, soap wash at 100°C for 5 minutes, then wash with water and dry to obtain a woolen fabric with certain brightness and color fastness. The dyeing process curve is attached figure 1 shown.

Embodiment 3

[0037] Select pure wool fabric for dyeing, specifically:

[0038] The woolen fabric that wetting is put into the solution that contains mordant stannous chloride, and the consumption of mordant is 10% (o.w.f.), bath ratio is 28: 1, and treatment temperature is 25 ℃, and treatment time is 90 minutes. After the mordant treatment, the woolen fabric is taken out, rinsed to remove excess mordant.

[0039] Other operations are the same as in Example 1. The dyeing process curve is attached figure 2 shown.

Abstract

The invention discloses a method for dyeing peony flower pigment onto protein fiber fabrics. The method uses peony flower pigment solution with concentration of 5-120g / L, pH value from 2 to 5 to dye the protein fiber fabric through direct dyeing method or mordant dyeing method, that is methods without or with mordant added, wherein the peony flower pigment solution includes a peony flower red pigment solution and a peony flower yellow pigment. The obtained protein fiber fabric has determined color fastness and brightness, which meets the environment protection requirements. The method is suitable for dyeing process for protein fiber fabric such as wool, silk or the like.

Description

technical field [0001] The invention relates to a method for dyeing natural pigments on protein fiber fabrics, more specifically, to a method for dyeing peony flower pigments, including peony flower red pigment and peony flower yellow pigment, on protein fiber fabrics. Background technique [0002] Natural dyes refer to dyes obtained from plants, animals or mineral resources with little or no chemical processing. According to the source, they can be divided into plant dyes, animal dyes and mineral dyes. Among them, plant dyes are more widely used in textile printing and dyeing. many. Plant dyes refer to colored substances extracted from the roots, leaves, flowers, trunks or fruits of plants. Common ones include madder, comfrey, sumac, indigo, safflower, pomegranate, holly, bayberry, persimmon, yellow gardenia, Mulberry, tea, etc. [0003] Dyeing with natural dyes has a long history in our country. During the Ming and Qing Dynasties, the preparation and dyeing technology of...
