している。When it comes to dyeing these ultra-fine fibers, there are several problems such as poor color development, which makes the color look faint for the same dye concentration and requires a large amount of dye, and the fiber surface becomes large and various fastness properties deteriorate. Although various studies have been carried out to address these problems, the problems of increasing the amount of dye used and limiting the types of dyes remain. Furthermore, in the case of textile printing, in addition to the above, a large amount of sizing agent is used, which further reduces the dyeing rate, and as for raised fabrics, since the coloring is carried out with the sizing agent applied, the raised fabric is susceptible to changes such as sagging. It has its drawbacks.
