Definitions

  • the invention relates to a process for the production of yarns from spun fiber tapes and their refinement to roving, which is consolidated by winding with a fine filament yarn, warping the roving in the drafting unit of a spinning machine to the desired yarn thickness and consolidating the resulting sliver, e.g. by granting rotation.
  • a draftable roving produced by winding with a filament yarn is described in DE-P-2 447 715.
  • the elongation at break of the wrapping filament yarns should be exceptionally low and that a certain geometric arrangement of the filament yarns in the roving is also necessary.
  • the object of the present invention is to avoid the disadvantages mentioned in the production of spun yarns from wrapped rovings.
  • the amount of warpage in the main drafting zone is about 15 to 40 times. If you prevent the tearing of the filament yarns in the pre-drafting zone by means of correspondingly lower warping in the pre-drafting zone and greater stretching, they will tear safely in the main drafting zone, provided that the filament yarns are securely clamped between the cylinders of the drafting system. Due to the tension of the filament yarn in the pre-drafting zone, the roving is evenly combined when entering the main drafting zone. This gives good conditions for an even delay.
  • Filament yarns with force-elongation properties can be used for the process, as are also common for other areas of application. However, quickly spun or partially drawn filament yarns can also be used.
  • the filament properties are essential for avoiding false warping, roving breaks and cracks.
  • the wrapping filament yarn must be able to build up enough frictional forces between its fibers when the roving is subjected to tensile stress, in order to form sufficient roving yarn strength together with the strength of the filament yarn.
  • the filament yarn has to develop a sufficiently high tensile force even at a low stretch. It is therefore preferred if the force-length change behavior and the titer of the filament yarn are coordinated in such a way that a minimum tensile force of 10 cN is developed in the filament yarn when stretched by 4%.
  • the roving bobbins 7 are plugged into a drain creel 9, with the roving 5 in the thread leader 93 will be drafted.
  • the discharge gate 9 is brought to the spinning machine and is brought into the working position between the drafting systems (11, 12).
  • the rovings are now guided through the draft zone 11 and the main draft zone 12 of the drafting system.
  • this drafting system can be designed as a clamping drafting system or as a pulling drafting system.
  • the filament yarn surrounding the roving is torn when the roving is drawn and this is drawn to the desired fineness.
  • the twine receives its twist by means of the twisting device 13 and is thereby wound onto cops.
  • a fiber band made of cotton fibers with a strength of 700 dtex is wound with a filament yarn with a strength of 9 dtex and an elongation at break of 20% to the roving.
  • This roving is drawn to a fineness of 200 dtex in a drafting system and solidified by twisting to form the yarn.
  • the advance was 1.5 times.
  • the wrapping filament yarn tore for the most part in the pre-draft zone, but short periods of time were also observed in which the pre-yarn was only tensioned in the pre-draft zone. This led to distortion with thick and thin spots in the yarn.
  • the roving from Example 1 is drawn to a fineness of 200 dtex in a drafting system and solidified by twisting to form the yarn.
  • the advance was 1.16 times.
  • the roving was only tense in the pre-draft zone.
  • the width of the roving when entering the main draft zone was significantly smaller than in Example 1 and very constant.
  • the filament yarn only broke in the main draft zone. No distortion of delay was observed.
