In ancient times, tie-dyeing was called "tying valerian" and "twisting valerian". The common anti-dye printed textiles in ancient times are "twisted valerian", "wax valerian" and "methyl valerian". It is a traditional and unique dyeing process of Han people. One of the traditional manual dyeing techniques in China is the dyeing method of partially knotting the fabric so that it cannot be dyed.

Tie-dyeing process is divided into two parts: knotting and dyeing. It uses tools such as yarn, thread and rope to tie, sew, tie, weave and clip the fabric. The process is characterized by using printing and dyeing technology to twist the thread into a knot in the printed fabric, then printing and dyeing, and then removing the twisted thread.

It has 100 variety of changing techniques, each with its own characteristics. For example, "rolling and twisting" is full of halo, which changes naturally and is interesting. What is even more surprising is that every kind of flower, even if there are thousands of flowers, will not be the same after dyeing. This unique artistic effect is difficult to achieve by mechanical printing and dyeing process.
