Today (March 23) afternoon, the Shenzhou 13 astronaut crew will cooperate with each other to conduct the second lesson of the Tiangong Classroom. During the orbit, the astronauts also brought the Traditional and Unique Chinese Folk Handicraft - Tie Dye to the space station, let's take a closer look at the details and mysteries in space tie-dye.
Astronaut Wang Yaping: Hello students, I am space teacher Wang Yaping, the last space lecture I showed everyone the surface tension of liquid in the weightless environment, you can see that in the weightless environment with pure water can make a large water balloon that cannot be done on the ground. Today I would like to show you another interesting phenomenon, which is also related to an intangible cultural heritage of our country.
Space teacher Wang Yaping first showed the obvious difference between space twist towels and the ground, the magical phenomenon of water attached to the hand under microgravity, and explained the capillary adsorption, paving the way for the introduction of tie-dye techniques.
Astronaut Wang Yaping: Here I would like to introduce you to one of our intangible cultural heritages, tie-dye. Tie-dye, also known as tie-valerian and valerian, is a traditional and unique dyeing process, which is generally divided into two parts: knotting and dyeing.
The next expected tie-dye demonstration began. Wang Yaping first used tools such as yarn, thread, and rope to tie, sew, tie, embellish, clip and other operations to keep the knotted part of the fabric in its original color, and then dye the fabric with dyes such as banlan root.
Astronaut Wang Yaping: The method of bundling directly affects the pattern of the final work, which is a key step, different lashing methods can produce different tie-dye patterns, and guess what kind of pattern I will tie out in a moment?
Astronaut Wang Yaping: Next we prepare the dye. This is the plate blue root dye powder that needs to be used for tie-dyeing, and after mixing it with water, it is the dye we want to use.
After the dyeing is completed, the binding part is disassembled, and the tie-dye work is formed in a light and natural, layered tie-dye work.
Tie-dye has a long history and has been very mature as early as the Eastern Jin Dynasty. Tie-dye products were widely used in women's clothing during the Southern and Northern Dynasties, and tie-dye textiles were very popular during the Tang and Song dynasties. In 2006, the tie-dye technique was approved by the State Council and selected as a national intangible cultural heritage. Space tie-dye allowed the students to feast their eyes and at the same time better understand the traditional culture of the motherland, and witnessed the wonderful integration of thousands of years of traditional culture and modern science and technology.
Wang Yaping: Students, look, the blue and white tie-dye works are complete! Isn't it beautiful? This is my tie-dye work, and students can try different ways of tying to make your own tie-dye work that is unique to you! Looking forward to seeing you all share! We'll see you next time!
