In the textile industry, Sodium Carboxymethyl Cellulose CMC can act as the sizing agent for the warp sizing of fabrics including cotton, gloria, chemical fiber and blend. The print paste of rayon fiber usually contains cleaning solvent with high boiling point, dye, water and enough thickening agents. Sodium Carboxymethyl Cellulose CMC is the thickening agent as well as the emulsifying agent, so it helps to uniformly mix the dye with high boiling point cleaning solvent with as well as to stabilize the dye suspension and thus to prevent the occurrence of sedimentation and the formation of foam in storage.
