Definitions

  • the invention relates to ribbons, such as writing tapes, printing tapes, color cloths and. Like. Used in typewriters, computers, etc., their manufacture and their use.
  • Ribbons such as writing tapes, printing blankets and the like.
  • the like have long been known.
  • US-A-3 749 222 describes woven printing blankets in which yarns from composite continuous synthetic filament yarns are used, in which at least two groups of filaments have different shrinkage properties.
  • Multi-component fibers of the matrix segment type in particular those that are wholly or partially split, are not mentioned in this American patent.
  • DE-A-2 908 101 has disclosed multi-component fibers of the matrix segment type per se, but no indication has been given of their use as already split yarns for color ribbons.
  • the object of the invention is therefore to produce ribbons that are characterized by good mechanical properties such as long life, dimensional stability, good impact resistance and. Distinct the like and allow a clear, clean typeface.
  • yarns are used which are fixed at 200 to 230 ° C.
  • yarns made of multi-component fibers of the matrix segment type are used for the weaving and yarns made of a one-component yarn are used as the warp.
  • Polyester yarn is particularly worth mentioning as one-component yarn.
  • Multi-component fibers with a polyamide matrix and peripheral polyester segments are preferably used. These multicomponent fibers expediently have a matrix: segment ratio, based on the cross section, of 7.5: 92.5 to 20 80.
  • the yarns preferably consist of multicomponent fibers which have bondings which extend selectively, in regions or almost over the entire length of the yarn.
  • the bonds can extend over the entire yarn cross section or over part of the same, these bonds then also being able to continue in the longitudinal direction of the yarn.
  • the ink ribbons are composed of yarns which consist of wholly or partially split multicomponent fibers.
  • the weft yarns consist of multi-component fibers of the matrix segment type and the warp yarns consist of a one-component yarn, polyester yarns being suitable as one-component yarn.
  • the yarns preferably consist of multicomponent fibers with a polyamide matrix and peripheral polyester segments, it being advantageous if the multicomponent fibers have a matrix: segment ratio, based on the cross section of the fiber, of about 7.5: 92.5 to 20:80.
  • Plain weave is particularly suitable as a binding for the arrangement of the yarns in the color ribbons.
  • the multi-component fibers of the matrix segment type can have coarse and fine denier segments. Particularly advantageous uses of the ink ribbons are the use for computer printing devices and electric typewriters.
  • multi-component fibers of the matrix segment type are to be understood as fibers which are composed of at least 2 different components which are essentially incompatible with one another, for example polyester and polyamide.
  • the matrix is the component in which the segments are more or less embedded. It can happen that the matrix completely envelops the segments or that the segments are only partially surrounded by the matrix. Both the matrix and the segments are arranged continuously with a substantially constant cross section over the entire length of the fiber.
  • Multi-component fibers of the matrix segment type which have at least 3 peripheral segments are preferably used in the context of the invention, at least some of the peripheral segments not being encased by the matrix, that is to say making up part of the edge of the cross section.
  • Cross sections of multi-component fibers of the matrix segment type are e.g. B. described in DE-A-2 809 346. They are shown schematically in Figures 1 to 7.
  • B represents the so-called segments and a the matrix. The segments are embedded in the matrix and are partially or completely enveloped by it, as is the case with some segments in FIGS. 3, 4 and 5.
  • Cross sections according to FIGS. 1 to 4 have peripheral segments with rounded surface parts, whereas cross sections, as shown in FIG. 6, have, in addition to a rounded part at the edge of the cross section, also substantially straight parts of the surface.
  • Cross sections according to FIG. 6 are also referred to as an orange profile.
  • the cross section shown in Figure 6 is also called six-orange.
  • Cross sections according to FIGS. 1 to 4 are also referred to as so-called gear profiles, wherein FIGS. 2 to 4 are so-called six-tooth gear profiles.
  • FIG. 3 also has an additional central segment; in FIG. 4 there are 3 further segments completely enveloped by the matrix.
  • FIG. 7 An asymmetrical and uneven arrangement of segments and the matrix is shown in FIG. 7.
  • fibers include both fibers of practically unlimited length, i.e. H. Continuous fibers to understand, which are often referred to as filaments or threads, as well as so-called staple fibers, which have been given the required length by cutting or tearing in a manner known per se.
  • the fibers can also be split by other methods, e.g. B. be carried out by treatment with water or other treatment baths, it being advisable to simultaneously expose the material to be treated to mechanical action.
  • Textured yarns with corresponding gluing points such as are used according to the invention for fabrics for the ribbons, are used, for. B. described in DE-A-2 908 101. These yarns in the retired fabric preferably have about 4 to 50 glue points per meter.
  • Bonding of the matrix and segments in the yarn can also be brought about in other ways than by the false twist method. For example, by using copolymers with a low melting point, it is possible to achieve bonds in the yarn if the yarn is subjected to a thermal treatment. If certain copolyamides are used as a component, bonding and splitting can be achieved by treatment with warm water.
  • multi-component fibers of the matrix segment type which have coarse and fine denier segments. Yarns of this type are described in DE-A-3 035 862.
  • the fabrics are produced using yarns made of multi-component fibers of the matrix segment type according to methods known per se.
  • the fabric is made in plain weave, but other weaves, e.g. B. twill or atlas, are possible.
  • the yarns are used with or without protective twist or as more less high-twisted yarns.
  • B. rotations of about 80 to 350 per meter may be appropriate.
  • the weaving setting can vary widely and depends on the yarn used and the area of application of the ribbon. So z. B. Settings of about 30 to 120 threads per cm possible. Of course, the setting also depends on the titer of the yarn used. So z. B. with a titer of 120 dtex 30 to 50 threads per cm, with a titer of 50 dtex 45 to 70 threads per cm and with a titer in the range from 20 to 30 dtex up to 120 threads per cm.
  • the number of warps per cm match the number of wefts per cm. So the number of warp threads in the fabric can be higher than the number of weft threads per cm. This also depends on the area of application, also on whether the fabric is composed only of multi-component fibers or whether other fibers, e.g. B. yarns made of one-component fibers can also be used, for example polyester yarns or polyamide yarns.
  • the titer of the yarns used can vary within relatively wide limits. Particularly suitable titers are 20 to 120 dtex, with 40 to 70 dtex being preferred.
  • the number of segments in the individual multicomponent fiber can also be varied. This makes it possible to obtain more or less fine fibrillated yarn. By increasing the number of segments in the multi-component fiber, it is possible to obtain very fine titers of the segments. Suitable combinations of the total titer of the yarns, the titer of the individual multi-component fibers and the titer of the individual segments or matrix components in the multi-component fiber make it possible to obtain interesting effects. Effects can also be achieved by varying the number of filaments in the yarn.
  • the ribbons according to the invention can be constructed entirely from the same multi-component fiber yarn. However, it is also possible to combine non-textured multi-component fiber yarns with textured multi-component fiber yarns. Common yarns made of one-component fibers, such as. B. polyester or polyamide yarns can be combined with the multi-component fiber yarns. It is possible, for example, to build up the chain from conventional smooth or textured one-component yarns and to use multi-component fiber yarns as weft yarn. It is also possible to use yarn made from natural fibers such as silk or cotton. Yarns made from regenerated cellulose can also be used.
  • the finished fabric can then be soaked with dye by customary methods. It is possible to produce dye ribbons with a uniform color. But you can also produce multicolor tapes according to the invention. The coloring can also be done by printing.
  • ribbons are accessible which have an excellent ink absorption capacity and which allow metered ink delivery, so that they can be used for a very long time before the ribbons have to be replaced by fresh ribbons or the ribbons have to be replaced again Color soaks.
  • they are equivalent to ribbons made from natural fibers and outperform ribbons made from common synthetic fibers.
  • the typeface, which can be achieved with the ribbons, is sharp and clear and the screening, which is often perceived as disadvantageous, can no longer be observed.
  • the ribbons according to the invention are characterized by long life, minimal stretch, excellent impact resistance. They are not arrogant or wavy and enable fonts that are also visually readable.
  • the multi-component yarns made of matrix segment fibers can be processed with any other yarn according to the invention. So it is possible to use silk and cotton yarn; It is particularly advantageous that the multi-component fiber yarns can also be processed with practically all other yarns made of synthetic fibers. It is possible to use multi-component yarns with both textured and non-textured yarns, e.g. B. to process polyester or polyamide yarns.
  • the multicomponent yarns themselves can also be used in textured and non-textured form alone or in combination with other yarns. Ribbons according to the invention can therefore be produced in a wide variety.
  • the ribbons can be made in conventional widths, e.g. B. as narrow woven ribbons in 13 mm width. But you can also produce larger widths, for. B. 19 mm or as printing ribbons with widths of 19 to 220 mm or as ink sheets with a width of over 220 mm. It can thus produce all the usual ribbons and special ribbons, such as z. B. be mentioned in DIN 2134.
  • the ribbons according to the invention can not only be used in conventional and electric typewriters, they are versatile, z. B. in calculating machines, booking machines, in cars that are also provided with a writing part, in booking machines, but especially in computing devices, in the nuclear medicine sector, as multi-zone ribbons and. the like
  • FIG. 23 An ink ribbon according to the invention is shown schematically in FIG. 23 means warp threads, 22 represents a weft thread and 21 is the color distributed in the fabric.
  • FIG. 9 shows the cross section of a yarn made of a fabric for an ink ribbon according to the invention.
  • the individual segments are completely separate, so that this representation shows a cross-sectional part in which the multi-component fiber is completely split.
  • Fig. 10 shows a cross section on which some bonds are visible.
  • the matrix there acts as a bonding component, as is visible in places.
  • a 13 mm wide band is woven in plain weave, the sides of which are not reinforced.
  • a multi-component yarn based on polyester / polyamide is used as the warp yarn, polyamide 6 being the matrix and the segments made of polyester.
  • a cross section according to the orange profile shown in FIG. 6 is used.
  • the warp yarn has a titer of 50 dtex and consists of 15 individual filaments.
  • a yarn made of the same multicomponent fiber as the warp is used as the weft.
  • the titer of the weft yarn is 50 dtex.
  • the number of filaments is 15.
  • the weave setting for the warp is 68 and for the weft 53 threads per cm.
  • the multicomponent yarn was partially split before weaving by false twists and fixing at a temperature of about 225 ° C and provided with bonds.
  • the fabric was finished in the usual way and dyed in a manner known per se with a commercially available dye.
  • a smooth polyester yarn (DiOLEN "") 50 dtex 36 filaments twist Z 160 in a setting of 65 threads per cm is used as the chain; a false twist textured, untwisted, multi-component fiber cross-section according to FIG. 6 with a polyamide matrix and polyester segments 50 dtex / 15 filaments in a setting of 46 threads per cm is used as the weft yarn.
