Embodiment 1
[0023] A method for dyeing wicker with natural indigo pigment, comprising the following steps:
[0024] (1) Indigo extraction: crush the plant raw materials to make raw material powder; mix the raw material powder, sucrose and water to prepare a fermentation substrate, and add calcium hydroxide of 0.2%-0.3% of the total mass of the fermentation substrate; after fermentation , water-soluble extraction, and low-temperature drying to obtain indigo pigment;
[0025] (2) Soaking in acid and alkali: firstly immerse the willow in clean water for 32 minutes, after taking it out, immerse the willow in hydrochloric acid solution at a temperature of 34°C for 43 minutes; then take out the willow and wash it in water, then immerse in sodium hydroxide solution, The temperature is 29°C, soaking time is 43min; take it out and wash it with clean water;
[0026] (3) Cooking to remove impurities: the willow after acid-base treatment is immersed in heated pool water, the opening is closed, and s...
Embodiment 2
[0040] Present embodiment 2 is compared with embodiment 1, and step changes in the following aspects:
[0041] Step (2) acid-base soaking, the process parameters are:
[0042]Immerse in a hydrochloric acid solution with a concentration of 0.38% at a temperature of 35°C for a soaking time of 47 minutes; then, take out the wicker, wash it with clean water, and then immerse it in a sodium hydroxide solution with a concentration of 0.28% at a temperature of 30°C for a soaking time of 46 minutes.
[0043] Step (4) steam dyeing, its process parameters are:
[0044] In the heating stage, the temperature rises at a rate of 5°C / 2min, to 68°C, and heats for 26 minutes; then, the temperature rises to 98°C, and heats for 3 hours; in the cooling stage, the temperature drops at a rate of 5°C / 4min, and drops to about 25°C.
[0045] Step (6) Infrared color fixing, the process parameters are:
[0046] The infrared light intensity is 500lux, the temperature is 43°C, and the time is 46min.

Abstract
The invention discloses a method for willow artwork dyeing through a natural indigo pigment. The method comprises the following aspects that (1) indigo extraction is conducted, specifically, a plant raw material is subjected to crushing, fermentation, water soluble extraction and low-temperature drying, and the indigo pigment is prepared; (2) acid-alkali steeping is conducted, specifically, a hydrochlric solution with the concentration being 0.3-0.4% and a sodium hydroxide solution with the concentration being 0.25-0.3% are used to steep a willow artwork correspondingly; (3) cooking for impurity removal is conducted, specifically, impurities in the willow artwork is removed through cooking; (4) steaming for dyeing is conducted, specifically, the indigo pigment with the mass being 11-13% that of distillation boiler water is added, and steam dyeing is conducted; (5) low-temperature drying is conducted, specifically, the dyed willow artwork is dried; (6) infrared color fixing is conducted, specifically, the willow artwork is wrapped through mixed slurry and placed under infrared lamplight with the illumination intensity being 470-520 lux for color fixing; (7) ultraviolet inspection is conducted, specifically, the willow artwork subjected to color fixing is placed under an ultraviolet lamp, and the color fixing condition is inspected; and (8) tung oil layer coating is conducted, specifically, the willow artwork qualified after inspection is coated with tung oil, and after drying, the willow artwork with the natural indigo pigment is prepared.
Description
technical field [0001] The invention belongs to the technical field of willow weaving handicraft processing, and in particular relates to a method for dyeing willow weaving with natural indigo pigment. Background technique [0002] Willow is one of the traditional folk handicrafts in China. It was used as a daily practical product in ancient times; with the improvement of living standards in modern society, people's demand for original ecological products is increasing day by day. Elegant, through novel design, it can be woven into various simple and natural, beautiful, light and durable handicrafts. Willow products have gradually developed into willow handicraft products, decorative items, daily necessities, etc., which are loved by people. Its production scale and product types, is also gradually expanding. The wicker itself has a single color. After being polished, the color is off-white. However, the wicker has a tough texture and is not easy to dye. At present, the wic...
