However, many of the currently available fabrics are blends of polyester and cellulose fibers (T / C), therefore, polyester fibers and cellulose fibers need to be dyed with different dyes, and because multiple dyes need to be used for dyeing, mixed fabrics often need to use different dyeing baths and perform different dyeing processes to perform different characteristics. Dyeing of fibers. Due to the blended fabrics of polyester fiber and cellulose fiber, different dyeing baths have been used in the industry for different dyeing projects in the past, which will increase the time of the dyeing process and increase the cost of dyeing. Therefore, how to develop a dispersive dye composition that can meet the needs of dyeing in the same dyeing solution (referred to as "one-liquid dyeing") has always been the goal of the industry. 3 This paper size is suitable for wealth ® »!
