Chinese Intangible Cultural Heritage - Plant Dyeing Techniques

Introduction

Plant dyeing (also known as botanical dyeing) is a traditional Chinese natural dyeing technique that extracts pigments from roots, stems, leaves, flowers, and fruits of plants to color textiles. This eco-friendly dyeing craft with thousands of years of history was inscribed on China's National Intangible Cultural Heritage List in 2014. More than just a dyeing technique, it embodies the Chinese ecological wisdom of "harmony between man and nature," producing naturally soft hues with unique artistic charm.
