Definitions

  • the invention relates to ribbons such as those used as writing tapes, printing ribbons, color cloths and the like. used in typewriters, computers, etc., their manufacture and their use.
  • Ribbons such as writing tapes, printing blankets and the like. have been known for a long time. It is possible, as described in DE-OS 2 453 674, to use stretch-oriented polyester films as carrier films for ink transfer ribbons. For many purposes, however, ribbons made of fabric are preferred.
  • the object of the invention is therefore a method that enables the production of ribbons with improved ink absorption, good color retention and metered ink delivery.
  • the object of the invention is also to produce ribbons that are characterized by good mechanical properties such as long life, dimensional stability, good impact resistance and the like. distinguish and allow a clear, clean typeface.
  • This object is achieved by a process for the production of ribbons by weaving yarns from synthetic fibers and dyeing the fabric, which is characterized in that yarns made of multi-component fibers of the matrix segment type are processed into a fabric and the fabric is dyed.
  • Yarns are preferably used which have adhesive bonds which extend punctually, in regions or almost over the entire length of the yarn. It is also possible to use yarns which have bonds which extend over all or part of the yarn cross section, these bonds then also being able to continue in the longitudinal direction of the yarn.
  • 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 invention also relates to ribbons made of fabrics which consist wholly or partly of yarns made of synthetic fibers and which are characterized by yarns made of multi-component fibers of the matrix segment type.
  • 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 ink ribbons are composed of yarns which consist of wholly or partially split multicomponent fibers. Yarns textured using the false twist method and fixed during the false twist at a temperature of about 180 to 230 ° C. are very suitable. These are preferably yarns which are fixed at 200 to 230 ° C. It is advantageous if 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 consist of multi-component fibers with a polyamide matrix and peripheral polyester segments, it being advantageous if the multi-component 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.
  • 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 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 Figures 1 to 4 are also referred to as so-called gear profiles, with Figures 2 to 4 being so-called six-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. 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 fiber can be split in the tissue. It is also possible to feed the textured yarns to a nip treatment fabric before they are processed. Splitting of the fibers can also be done by other methods, e.g. be carried out by treatment with water or other treatment baths; whereby it is recommended 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 e.g. described in DE-OS 2 908 101. These yarns preferably have about 4 to 50 glue points per meter in the retired fabric.
  • Bonding of the matrix and segments in the yarn can also be brought about in other ways than by the false twist method.
  • copolymers with a low melting point it is possible to achieve bonds in the yarn if the yarn is subjected to a thermal treatment.
  • gluing 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 more detail in German patent application P 30 35 862.4 from September 23, 1980.
  • the fabrics are produced using yarns made of multi-component fibers of the matrix segment type by methods known per se.
  • the fabric is made in plain weave, however other weaves, e.g. Twill or Atlas are possible.
  • the yarns are used with or without protective twist or as more or less high-twisted yarns.
  • 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. For example, Settings of around 30 to 120 threads per cm are possible. Of course, the setting also depends on the titer of the yarn used. For example, 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 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. Yarns made from one-component fibers are also 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 animal of the yarns, the titer of the individual multicomponent fiber and the titer of the individual segments or matrix components in the multicomponent 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 from one-component fibers, e.g. 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 F arbstoffb suitable with uniform color. M an can also produce multicolor ribbons according to the invention. The coloring can also be done by printing.
  • ribbons are available 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 soaked with color.
  • 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 work with silk and cotton yarn; It is particularly advantageous that the M also ehrkomponentenfasergarne with virtually all other fabrics of synthetic fibers can be processed. It is possible to process the multicomponent yarns with both textured and non-textured yarns, for example 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.
  • silk 1 can be substituted in many areas.
  • ribbons can be made in common widths, e.g. as narrow woven ribbons with a width of 13 mm. But larger widths can also be produced, e.g. 19 mm or as printing ribbons with widths from 19 to 220 mm or as color blankets with a width of over 220 mm. According to the invention, all customary ribbons and special ribbons, such as those e.g. be mentioned in DIN 2134.
  • the tapes can be easily placed on spools or cassettes.
  • the ribbons according to the invention can not only be used with conventional and electric typewriters, they are versatile, e.g. in calculating machines, booking machines, in carriages which are simultaneously provided with a writing part, in booking machines, but in particular also in computer 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 multi-component yarn was partially split before weaving by false twists and fixing at a temperature of about 225 0 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 wide fabric in plain weave is produced.
  • the chain becomes a smooth polyester yarn (DIOLEN) 50 dtex 36 filaments twist Z 160 used in a setting of 65 threads per cm; 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.
