Reactive yellow PW-4G for wool is suitable for the dyeing of wool loose fibers, tops, and fleece, and is rarely used for dyeing cloth. The leveling property is poor, the fastness is good, and the fabric has bright color after dyeing. Dyeing should be carried out in a dye bath with acetic acid, ammonium sulfate and levelling agent to improve levelling. It can also be used for printing silk and wool fabrics.
