Embodiment 1

[0024] Take the concentration of 2g / l titanium sulfate as mordant, bath ratio of 1:50, mordant temperature of 40℃, mordant cotton fabric, mordant time of 60 minutes, take out the fabric, put in 2g / l goldenrod dyeing Dyeing in the liquid, the bath ratio is 1:50, the dyeing temperature is 95°C, after discharging, rinse with water and dry.

Embodiment 2

[0026] Take ferrous chloride with a concentration of 2g / l as mordant, bath ratio of 1:50, mordant temperature of 40℃, mordant silk fabric, mordant time of 60 minutes, take out the fabric and put in a 2g / l sprig Dyeing in yellow flower dyeing liquor, liquor ratio is 1:50, dyeing temperature is 95℃, after discharging, rinse with water and dry.

Embodiment 3

[0028] Dye the cotton fabric with a goldenrod dyeing solution with a concentration of 2g / l. The bath ratio is 1:50 and the dyeing temperature is 95℃. After dyeing, the cotton fabric is taken out and put into the titanium sulfate mordant solution for mordant dyeing and mordant dyeing. The agent concentration is 2g / l, the bath ratio is 1:50, the mordant temperature is 40°C, and the mordant time is 90 minutes, then add water to rinse and dry.

Abstract

The invention relates to a dyeing method for a common goldenrod herb natural dye. The dyeing method comprises the following steps: preparing a 2 to 20 g / I common goldenrod herb dye, and setting a dyeing temperature of 40 to 100 DEG C, a bath ratio of 1:50 to 200 and dyeing time of 10 to 90 minutes; taking a 2 to 20 g / I mordant solution, and setting a mordanting temperature of 40 to 100 DEG C and mordanting time of 10 to 90 minutes; and adding a mordant before or after natural fiber yarn or natural fiber textile is added into common goldenrod herb dye liquor or simultaneously when the natural fiber yarn or the natural fiber textile is added into the common goldenrod herb dye liquor for one-bath dyeing. The method uses the prior textile dyeing device for direct dyeing without adding devices or increasing cost. The textile dyed by the method is soft, primitive and simple and natural color, and has good dye fastness, no fading, no discoloring, good reproducibility, and chromatic aberration around a half level. The method is suitable for the industrialized production, and has no toxicity, no harm and no pollution.

Description

Technical field [0001] The invention belongs to the field of dyeing textiles, and particularly relates to a dyeing method of a yellow flower natural dye. Background technique [0002] Solidago canadensis, also known as yellow flower grass, snake head king, mountain grass, or zinnia, is native to North America, also known as "rough solidago", is a perennial herb of the Compositae family. According to records, the Canadian Solidago was introduced to my country as an ornamental plant in 1935. It was first cultivated as a garden flower in Shanghai and Nanjing, and later it grew in the wild. In the 1980s, it began to spread to the Jiangsu and Zhejiang areas of our country. In autumn, it will appear in some flower shops in Jiangsu and Zhejiang as a matching flower similar to gypsophila. At present, it has developed into a widely distributed exotic weed in East China. Solidago canadensis plants are sturdy, up to 2.50 meters in height, and often form tall single-dominant populations in a...
