Processing technology of Valeriana amurensis

Wenzhou Lanjiayu is the source of carving, printing and dyeing in China. Its skills have been widely spread in Wenzhou, southern Zhejiang, and Cangnan County and two county-level cities, Rui 'an and Yueqing, have been well protected and passed down. The representative inheritors of Lanjiawei's skills are Hu Yizao, Chen, Huang, Zhang and Xue Xunlang. Raw materials and weaving with tools-main materials: cotton yarn, rice soup, etc. Main tools: spinning wheel, loom, etc. Wood carving-main materials: wood carving, paper, paste, etc. Main tools: carving tools, shovels, drills, brushes, etc. Indigo-main materials: Indigo branches and leaves, sea ash, etc. Main tools: bamboo sticks, indigo rakes, wooden barrels, dense screens, indigo baskets, etc. Printing and dyeing-main materials: engraving, indigo, grey cloth, etc. Main tools: dye vat, metal gem, lever sleeve, cloth dyeing shed, etc. Process flow and method

Including weaving, carving, indigo production, printing and dyeing. : 1, and the weaving process includes spinning, sizing and weaving. 2. The carving process includes pasting chalk books, carving patterns, dredging waterways and restoring chalk books. 3. The process of making indigo includes soaking, pulping, sieving and precipitation. 4. The printing and dyeing process includes dye liquor fermentation, grey cloth plate mounting, coloring in the lower cylinder, rinsing and drying. Valeriana amurensis has many processes, from indigo to carving to printing and dyeing. First of all, indigo is harvested in October every year, and indigo master turns indigo plants into indigo dyes for printing and dyeing through production links including more than ten processes; Secondly, prepare high-quality woodcuts. Woodcut patterns are mainly based on auspicious patterns such as figures, flowers, birds and animals in traditional dramas. The artists carefully carved lifelike figures and animals. On the basis of the first two processes, printing and dyeing can be completed through as many as 30 processes. Valeriana officinalis is a living fossil of block printing and dyeing, with complicated technological process and exquisite craftsmanship, which has been passed down by hand for hundreds of years.

1, desizing. Boil the grey cloth in a pot and soak it to remove the pulp.

2. Tidy up the cloth. Fold the semi-wet grey cloth according to the requirements of carving size.

3. Last edition. Clip the folded grey cloth in the carving.

4. Sheung Wan. Cover the whole splint with iron hoops (a pair of rigid plates is 17, which just clamps a quilt cover).

5, knock on the flower version. Knock the tenon into the upper end of the splint group with a mallet, and knock more and more tightly until it can't be knocked in.

6, pick the edge of the cloth. Use bamboo sticks to spread the edges of grey cloth exposed outside the clamp group to prevent sticking together, and use small bamboo sticks to support important parts for uniform coloring.

7. Lower the cylinder. Put the heavy cloth group into the dye vat.

8. Printing and dyeing. The cloth board group is lifted once every 10 minute in the dye vat, and repeated several times, depending on the color, during which it needs to be turned over for dyeing.

9. Get out of the tank. Take out the dyed cloth group.

10, flushing. Put the cloth group on the shelf off the ground and wash the floating color on the surface with clear water.

1 1, water absorption. Wrap the cloth ball with cloth and sprinkle with plant ash to absorb water.

12, being dismantled. Remove the iron hoop on the cloth tray group and take out the cloth.

13, hanging cloth. The dyed blue clip can be dried on a high bamboo frame. Around the middle of June in the lunar calendar, indigo leaves are mature, yellow-green, and the stem is about one meter high. When the juice is crushed with your fingers and turns green, you can pick and cut it at this time and pick it again every two or three months. If the blue leaf contains indigo, it can be extracted by soaking it in water and fermenting it. The soaking time can be 80- 100 hours (depending on the temperature). At the same time, alkali lime is added at the ratio of 10% and stirred to oxidize it, so that indigo is precipitated. After indigo is precipitated, the water in the upper layer is removed, then it is filtered to make indigo paste, and then it is stored in a constant temperature box, and enough water is kept in the indigo paste. When in use, starter and fermentation medium are added to make indigo become a plant dye for dyeing Valeriana officinalis.
