を特徴とする。 Traditionally, typewriter ribbons have been made using nylon 6,6 filament yarn as the main material due to its wear resistance, and have been woven in plain weave or twill weave by twisting or increasing the weave density. . In addition, filament fabrics with special cross-sectional shapes have been proposed from the viewpoint of ink retention (Japanese Patent Laid-Open Nos. 117988-1988, 117989-1989, 120484-1984). . Normally, such a ribbon is impregnated with ink, wound up into a spool, and sent to a printing point in a printing section for printing. As ribbons are used, ink is consumed, printing becomes unclear, and the lifespan of the ribbon is shortened. Therefore, the key to determining the quality of a product is how to improve ink retention. However, in recent years, printers with built-in ink supply parts have appeared, and the lifespan has come to be determined by mechanical wear and tear of the ribbon itself rather than ink retention. As a result of various studies on extending the life of ink ribbons suitable for such printers, the inventors of the present invention found that
We have arrived at this idea. That is, the present invention is characterized in that the back surface of the synthetic fiber cloth is lined with a fluororesin sheet in spots with dotted or linear adhesive.

良した繊維からなる布帛であつてもよい。 To further explain the present invention with reference to drawings, FIG. 1 is an explanatory diagram showing an example of an ink ribbon according to the present invention, in which 1 is a synthetic fiber cloth and 2 is a fluororesin sheet. The synthetic fiber fabric 1 is, for example, 30d/24f,
Using 30d/26f, 40d/34f, 50d/34f, 70d/34f polyamide filament yarn, polyester filament yarn, mixed filament yarn, etc., warp density
Fabrics with a weft density of about 160 to 170 threads/inch and a weft density of about 105 to 110 threads/inch are preferred, but are not limited thereto, and fabrics subjected to calendar processing or weight reduction processing as described in Japanese Patent Publication No. 46-27506. It may be. In addition, in order to improve ink retention, modified fibers or fibers are produced by blending a polymer for yarn production with a micropore-forming agent, such as silica, kaolin, or an incompatible polymer, spinning and drawing it, and then treating it with an alkali or a solubilizer. It may also be a fabric made of fibers whose ink retention properties have been improved through post-processing.

字の鮮明性が劣る欠点を生じる。 As the fluororesin sheet 2, in addition to films of fluorine-containing polymers such as polytetrafluoroethylene, polyfluoroethylene, propylene, polyfluorochloroethylene, and polyvinylidene fluoride, JP-A-50-22881,
It may also be a porous sheet of polytetrafluoroethylene produced by extrusion molding and stretching or rolling as disclosed in JP-A-51-18991 and the like. In particular, porous sheets are preferred from the viewpoint of ink retention, flexibility, and the like. The thickness of the sheet 2 is 1 to 300 μm, preferably 10 to 100 μm, but is not particularly limited thereto. If the thickness is too thin, the ribbon life will be shortened, while if it is too thick, the ribbon will harden, resulting in poor print clarity.

であり黒側）のみ裏打ちしてもよい。 The synthetic fiber fabric 1 and the fluororesin sheet 2 are usually bonded together using an adhesive such as an isocyanate, polyurethane, or cyanoacrylate adhesive in dotted or linear spots. In this case, the adhesive surface of the fluororesin sheet may be etched in advance to improve the adhesive properties of the fluororesin sheet. Further, ink ribbons of two colors (for example, red and black) may be lined only on one side (usually the black side because black is used more frequently).

いる。 Ribbons lined with synthetic resin films such as polyester and polyamide have unsatisfactory mechanical strength, while polyester films that are biaxially stretched to improve mechanical strength are too rigid, causing the sheet to harden and cause printing problems. It has the disadvantage of poor clarity. On the other hand, the fluororesin sheet of the present invention, particularly the polytetrafluoroethylene porous sheet, has the advantage of being flexible and having excellent mechanical properties and abrasion properties.

案の複合シートは4000回以上の耐久性を示した。Example 1 Taffeta made of nylon 6,6 filament (40d/34f) yarn with a weave density of 172 x 117 threads/inch was scoured and heat set in a conventional manner. Next, a polytetrafluoroethylene film having a thickness of 100 μm was dot-bonded using a polyurethane adhesive to obtain a laminate sheet.
This composite sheet was slit to a width of 13 mm, and a test was conducted in which dots were printed at the same location using a typeface without using ink. As a result, when using only nylon taffeta, thread breakage occurred between 2,000 and 2,500 times, but the composite sheet of the present invention showed durability of more than 4,000 times.

ンクが赤インク部へ移行した。Example 2 The same nylon 6,6 taffeta as in Example 1 was heat-set, then slit to a width of 13 mm, and a polytetrafluoroethylene porous sheet (pore diameter 1 to 5 μm, Laminated with a density of 0.5g/cc). In addition, on the taffeta side, a separation line with a width of 1 mm was created using silicone in the center of the 13 mm width. After this, apply black ink to the polytetrafluoroethylene sheet side.
Red ink was applied to the non-laminated side. This was made into a loop with a circumference of 350 mm, and a dot test was performed while supplying red and black ink separately. At this time, the subjects were instructed to make dots on the red ink side once for every five dots on the black ink side. As a result, there was no damage even after 50,000 dots were made using a black ink base, and no phenomenon of black ink bleeding into red ink areas was observed. On the other hand, when a ribbon without backing was tested, the ribbon broke after 20,000 dots and the black ink migrated to the red ink area.
