Abstract
A discharge printing device includes an application unit configured to apply a reducing agent to fabric and a contact heating unit configured to subject a reducing agent-applied area to contact heating and satisfies any of the conditions (a1)-(c1) and (d1)-(e1): the conditions (a1)-(c1): in the contact heating, a heating temperature is 100° C. or more, and a heating time is 60 seconds or more; the conditions (d1)-(e1): the contact heating unit subjects the reducing agent-applied area to contact heating to accelerate a reduction reaction and subjects, after the acceleration of the reduction reaction, the reducing agent-applied area to contact heating to accelerate an oxidation reaction, or the discharge printing device further comprises a non-contact heating unit, and the non-contact heating unit subjects, after the acceleration of the reduction reaction, the reducing agent-applied area to non-contact heating to accelerate an oxidation reaction.
