Introduction to unique varieties: In the long history of Yun brocade, many varieties of designs and colors have been produced, forming a unique series of varieties, which are mainly divided into four categories: "Ku satin", "Zhijin", "Ku brocade" and "Zhuanghua" Among them, "Zhuanghua" is the most representative variety unique to Nanjing Yunjin. The characteristic of "Zhuanghua" fabrics is that they use many colors and have rich color changes, including Zhuanghua satin, Zhuanghua yarn, Zhuanghua silk, Zhuanghua brocade, Zhuanghualuo, Zhuanghua silk, Zhuanghua velvet, Jinbaodi, etc.; but There are colored threads on the back of the fabric that are not resistant to friction, and the colored velvet is thicker in the pattern part, but there is no colored velvet in the ground pattern part, so the thickness is uneven.
