Abstract: Cordless-iron apparatus in which the sole plate of the cordless iron is covered with a polyimide film synthesized by a polycondensation reaction between an aromatic tetrabasic acid and an aromatic amine. Such a film exhibits a broad range of temperature stabililty, thus permitting the heating of the sole plate to relatively high temperatures without wrinkling of the film and without causing scorching of the fabric to be ironed. Steam pressing without spotting is achieved by metering the water flowing to the heated recess in the non-exposed region of the sole plate, which sole plate has apertures for the passage of steam therethrough, the polyimide cover for the sole plate also being apertured.
