Title: Base fabric for ink ribbon
Inventor: YAHASHI YASUO
IPC: B41J31/00
Filed: 1988-03-31
Abstract: PURPOSE:To enable clear printing without generating high spots, by refining and setting a gray fabric comprising specified synthetic fiber multifilaments and having a warp-to-weft density ratio in a specified range, thereby bringing the density ratio into a specified range. CONSTITUTION:A base fabric for an ink ribbon is obtained by refining and setting a gray fabric comprising 10-110 denier synthetic fiber multifilaments and having a warp-to-weft density ratio of 0.56-0.73, thereby bringing the density ratio into the range of 0.64-0.71. If the fineness of the synthetic fibers is more than 110 deniers, the base fabric obtained is so thick that it is difficult to perform high-speed printing therewith by a printer, and the base fabric is poor in denseness, so that it lacks properties for clear printing. If the fineness is less than 10 deniers, process performance is poor, and an ink ribbon base fabric with favorable quality can not be obtained. If the ratio of warp density to weft density is more than 0.63, strain in the base fabric can not be removed, and generation of high spots can not be obviated. If the density ratio is less than 0.56, it is necessary to adopt a high tentering degree and a high overfeeding degree, so that there arise the problems of breakage of selvage due to over-tentering and wrinkling due to overfeeding in excess of the shrinkability of the gray fabric.
