Problems solved by technology

Due to the complex production process of Xiangyun yarn, the cooking, dyeing and drying are all manual operations, the labor intensity is very high, the production process is long, and it especially relies on sunlight to "depend on the sky", which consumes a lot of raw materials, high cost, and is fragrant. The biggest defect of cloud yarn is its single color. Therefore, with the emergence of a large number of new textile fibers and textile products with various and low prices in the market, it has lost its competitiveness, and the product is facing withering.
In order to protect the traditional silk products and further develop the market, it is necessary to transform the traditional silk yarn production methods and techniques, to change the status quo of low output, difficult quality control, poor reproducibility, and single color of manual production, and to realize industrial production.

Embodiment 1

[0016] (1) Preparation of Ranunculus yam extract: Peel and crush the tubers of Ranunculus yam, weigh a certain mass of Ranunculus yam powder according to the solvent-solute ratio of 20:1, extract with 60% acetone aqueous solution in a constant temperature water bath at 60°C for 2 hours, and let it stand After the precipitate was filtered, the acetone was distilled off under reduced pressure to obtain the yam extract.

[0017] (2) Dipping treatment of real silk: Dilute the stock solution of Panicum yam extract into an impregnating liquid, heat up to 60°C at a bath ratio of 1:50, and the concentration of the Panicum yam extract can be determined according to the concentration of the stock solution and the final dyeing depth required for the product To adjust, immerse 11206 silk electric spinning in the above dipping solution, and treat it at a constant temperature for 75 minutes.

[0018] (3) Complexation treatment: treat the impregnated silk at 30° C. in 15% ferrous sulfate (ra...

Embodiment 2

[0020] According to the step (1) of Example 1, prepare the yam extract, (2) soak the silk, then treat the treated silk with 12% titanium sulfate (ratio W / W to the fabric mass) at 30°C. (adjust the pH to 3 with a buffer solution) for 15 minutes, then raise the temperature to 85°C at 3°C / min, shake at a constant temperature for 30 minutes, take out the soap, boil it, wash it with water, and dry it in the air. The obtained silk is orange-yellow (reddish), and the color fastness performance of the obtained product is shown in Table 1, and other comprehensive properties such as anti-ultraviolet radiation are shown in Table 2.

Embodiment 3

[0022] (1) Preparation of Panicum yam extract: same as Example 1.

[0023] (2) Dipping treatment of real silk: same as in Example 1.

[0024] (3) Complexation treatment: the real silk processed by the extract solution continues to be treated at 30° C., 6% zinc chloride (ratio to fabric mass W / W) treatment bath (adjusting pH to 7 with a buffer solution) for 15 minutes, Then raise the temperature to 75°C at 3°C / min, shake at a constant temperature for 30 minutes, take out the soap, boil it, wash it with water, and dry it in the air. The obtained silk is light yellow (reddish), the color fastness performance of the obtained product is shown in Table 1, and other comprehensive properties such as anti-ultraviolet radiation are shown in Table 2.

Abstract

The present invention discloses process of dyeing silk with dye yam extract, and belongs to the field of fabric dyeing and finishing technology. The process includes dip dyeing silk in dye yam extract liquor, and post-dyeing treatment with mordant of ferrous sulfate, titanium sulfate, copper sulfate, aluminum sulfate, zinc chloride or ferric chloride to obtain different colors. The present invention has the advantages of high color fastness, homogeneous dyeing and environment friendship, and the dyed silk is soft, antiseptic and ultraviolet ray shading.

Description

technical field [0001] The invention relates to a method for dyeing natural silk dyes, in particular to a method for dyeing real silk by using yam yam extract as a dye solution, and belongs to the technical field of textile dyeing and finishing. Background technique [0002] Ranunculus yam is a perennial twining vine wild plant, belonging to the family Dioscoreae, rich in Guangdong, Guangxi, Yunnan, Guizhou, and other places in my country. It can be used as a Chinese herbal medicine and has hemostatic and antibacterial effects. Tannin, a polyphenolic compound contained in Buttercup, can complex with metal ions to form a ring-shaped chelate, and the formed chelate is generally colored. Guangdong's famous traditional handicraft "Xiangyun yarn" (also known as Ranunculus silk) is dyed with yam juice, and then coated with iron-rich river bottom mineral mud, using tannins to chelate with iron ions. Produces positive and negative special effects of differ...
