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 Dioscorea spp.: Peel the skin and smash the tuber of Diossigma, weigh a certain quality of dioscorea powder according to the solvent-solute ratio of 20:1, and extract it with a 60% acetone aqueous solution in a constant temperature water bath at 60°C for 2h, and then stand still After the precipitation was filtered, the acetone was distilled off under reduced pressure to prepare the dioscorea spp.

[0017] (2) Real silk dipping treatment: Dilute the yam extract extract into a dipping solution, and heat to 60℃ at a bath ratio of 1:50. The concentration of the yam extract can be based on the concentration of the original solution and the final dyeing depth required for the product Adjust, immerse the 11206 silk power spinning in the above-mentioned immersion liquid, and treat it at a constant temperature for 75 minutes.

[0018] (3) Complexing treatment: Treat the impregnated silk in an aqueous solution of 15% ferrous sulfate (w / w to the fabric mass) at 30°...

Embodiment 2

[0020] Follow the steps of Example 1 (1) to prepare the dioscorea extract, (2) the real silk dipping treatment, and then put the treated real silk in a bath of 30℃, 12% titanium sulfate (ratio W / W to the fabric mass) (Adjust the pH to 3 with a buffer solution) for 15 minutes, then heat up to 85°C at 3°C / min, shake at a constant temperature for 30 minutes, take out, saponify, wash in water, and dry. The obtained silk is orange-yellow (reddish light), the color fastness properties of the obtained product are shown in Table 1, and the UV resistance and other comprehensive properties are shown in Table 2.

Embodiment 3

[0022] (1) Preparation of dioscorea extract: the same as in Example 1.

[0023] (2) Real silk impregnation treatment: same as Example 1.

[0024] (3) Complexing treatment: The silk that has been treated with the extract is continuously treated at 30°C in a 6% zinc chloride (ratio to fabric mass W / W) bath (adjusted to pH 7 with a buffer solution) for 15 minutes, Then, the temperature was raised to 75°C at 3°C / min, and after shaking at a constant temperature for 30 minutes, it was taken out for soaping, washed with water, and dried. The obtained silk is light yellow (reddish light), the color fastness properties of the obtained product are shown in Table 1, and the UV resistance and other comprehensive properties 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 with natural dyes, in particular to a method for dyeing real silk with a dioscorea extract as a dyeing solution, belonging to the technical field of textile dyeing and finishing. Background technique [0002] Dioscorea is a perennial twining vine wild plant belonging to the Dioscoreaceae family. It is abundant 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 polyphenol compound contained in Dioscorea nigra, can be complexed with metal ions to form a cyclic chelate, and the chelate formed is generally colored. Guangdong traditional craftsmanship "Xiangyunsha" (also known as crowfoot silk) is to dip silk blanks with yam juice, and then coat with iron-rich river bottom mineral mud, using tannins to chelate with iron ions. Produce special effects of positive and negative colors. Frag...
