扎染, or "tie-dye," is a traditional fabric dyeing technique that originated in ancient China. It involves folding, twisting, or bunching fabric and then binding it with string or rubber bands before applying dye. This method creates unique patterns and designs, as the tied areas resist the dye, resulting in beautiful contrasts. The process of 扎染 can be done using various types of dyes, including natural and synthetic options. It is often used to create colorful textiles, such as clothing and home decor. Today, 扎染 remains popular not only in China but also around the world, celebrated for its artistic expression and cultural significance.
