Is plant knock-out dyeing a traditional culture?

Plant tapping dyeing is a traditional culture. Plant knock-out dyeing is an extended dyeing method, which takes roots, stems, flowers, leaves, fruits and skins of plants as dyeing materials, extracts their juices by knocking out and dyes them on natural fiber materials. It belongs to a relatively unpopular and simple category in plant dyeing. This technology is similar to the ancient embossing process, but it retains the faint traces of flowers and plants through kneading. Those beautiful flowers or flowers that fade easily in summer, through the method of plant rubbings, leave a picture of the fragrance, texture, color and warmth of the encounter.
