Process for Printing on Polyester, Polyester Blended, Polyester Mixed or Cellulosic Fabrics

摘要

A process for imparting a controlled diffused print effect on polyester, polyester blended or polyester mixed fabrics consisting of pure or blended spun polyester yarn at least in the warp or weft, printing the said fabric with a printing paste containing at least a suitable known disperse dyestuff for polyester only, a known thickening agent and an auxiliary agent having normally a capillary action and further also capable of dissolving a part of the dyestuff, said step of printing being effected thereby reversing the normal capillary action of the auxiliary agent, drying said fabric and, thereafter, subjecting the fabric to a step so as to cause an activation of the capillary action of said auxiliary agent and simultaneously fixing the dye to the fabric, followed by the usual washing, to give the desired effect on the fabric. The auxiliary agent may preferably be polyethylene glycol, 2-anilino-ethynol, dibutyl butyl phosphonate oleic acid or diethylene glycol.
