Due to its specification of 38mm-76mm and 4.5D-25D, it is more spinnable and touched like wool. This kind of high-quality color fiber has good color fastness, small color difference, perfect resistance to water washing, and can obtain different results by the adjustment of colors. In addition, its chromatography is extremely wide, including orange, red, green, yellow, blue, indigo, and violet colors, and the derived various chromatography. Our wool-like polyester staple fiber has improved spinnability and physical specifications for it is made by a special production process. With its high strength and fewer flaws, it is brighter and softer than common polyester staple fiber.
