PURPOSE:To enable erasing of a letter printed on a fabric in a short time with ease of handling, by using a print erasing liquid containing propylene glycol monomethyl ether. CONSTITUTION:A print erasing liquid which contains propylene glycol monomethyl ether and is used for erasing a letter printed on a fabric. The liquid can be formed either as a one-pack product containing propylene glycol monomethyl ether and a reductive or oxidative bleaching agent, or as a two- pack product comprising a first liquid containing propylene glycol monomethyl ether and a second liquid containing a reductive or oxidative bleaching agent. Examples of the reductive or oxidative bleaching agent include sodium hypochlorite, calcium hypochlorite, oxalic acid, and citric acid. Additives used in a conventional ink eraser can be added to this print erasing liquid, if necessary. |
