3. Introduction to the dyeing process of suede fabric produced by polyester microfiber The dyeing of polyester microsuede is much more difficult than ordinary polyester fabrics. Due to the large surface area of the microfiber itself, it has remarkable characteristics in terms of dyeing speed, levelness, reproducibility and color fastness. The microfiber has fine fineness, large surface area, fast dye adsorption and slow diffusion, so the levelness is poor; the light reflection coefficient of microfiber is large, and the amount of dye to be dyed with the same depth of color is 3 higher than that of ordinary fibers. The light fastness, sublimation fastness and abrasion fastness of microfiber fabrics are all lower than those of conventional synthetic fibers. Usually its sublimation fastness should drop by 1-2 grades.
