The purpose of Disperse Red 1 Quotation:
Disperse Red 1 Quotation is mainly used for dyeing polyester fiber (polyester), acetate fiber (diacetate, triacetate) and polyamide fiber (nylon) in chemical fibers, and has a small amount of application for polyacrylonitrile (acrylic).
The chemical fiber textile products printed and dyed by the disperse dye Disperse Red 1 Quotation have bright colors, excellent washing fastness and a wide range of uses. Because it is insoluble in water, it has no ability to dye cotton, hemp, wool and silk in natural fibers, and it has almost no staining on viscose fibers. Therefore, chemical fiber blended products usually need to use Disperse Red 1 Quotation in conjunction with other applicable dyes. .
