ABSTRACT:
Disperse dyes are dischargeable to white with a print paste including a thickening agent, lithium hydroxide, an organic acid, a polyethylene glycol compound, a polyoxyethylene sorbitan fatty acid ester and a polyalkyleneglycol ether. The print paste discharges a number of known disperse dyes, some which have been conventionally thought of as being alkali-resistant. A method of discharge printing of synthetic textile materials (e.g. polyester) is also disclosed.
