Definitions

  • the spinning processes which are nowadays conven tional encompass, among other things, in termination of the doubled band or sliver at the outlet of a final drawing frame passage one or more flyer or slubber passages for the manufacture of a twisted condensed sliver or roving, which is then drafted by using a break or preliminary draft and with the application of a twist is wound upon the ring spinning-drafting arrangement in the form of a yarn.
  • the spinning process via the flyer or slubber has, however, in addition to the limitation with respect to the number of revolutions, the great disadvantage that the roving produced by the flyer brings with it conceivably bad conditions for the drafting process at the ring spinning frame.
  • the rovings in consequenc of their twist exhibit numerous protruding fibers, are susceptible to contamination by fly, easily damageable and also insufiiciently sturdy for processing, which results in defective drafting.
  • the surface inhomogeneities become more pronounced by the guide rod-s, blower installations, condensers and so forth and, as a result thereof render impossible each controlled, uniform continuous drafting.
  • the result thereof is the presence of more or less pronounced, thick and thin locations at the yarn and a corresponding increase of yarn breakage in addition to a general loss in quality.
  • the band or sliver spinning process generally designed as direct spinning, in which in the final stage a very voluminous sliver or band must be drafted in a number of drafting zones arranged behind one another. In so doing, it has proven to be necessary to always again combine or gather together the fiber formaton by means of condensers before each drafting zone. In order to handle the drafting of such a voluminuous band or sliver at sliver spinners very complicated constructed drafting arrangements subject to malfunctions are thus necessary. The thus produced yarn quality also leaves something to be desired.
  • the slubber or flyer which follows the drawing frame is eliminated and replaced by a sliver machine which delivers highly parallelized, non-twisted, smooth, set or fixed slivers or bands which, however, are still easily draftable by a single-zone drafting arrangement on the ring spinning frame.
  • a sliver machine which delivers highly parallelized, non-twisted, smooth, set or fixed slivers or bands which, however, are still easily draftable by a single-zone drafting arrangement on the ring spinning frame.
  • the sliver exhibit-s a pronounced, small specific volume which first renders possible the decisive advancement, namely, the accomplishment of the drawing or drafting operation in a single-zone drafting arrangement. Due to abandoning of a roving twist there results an increase in production in consequence of the increased efficiency of the above-mentioned sliver machine in comparison with the slubber, the speed of which can be compared with respect to that of a drawing frame.
  • the obtained yarns manifest themselves by improved uniformity and the elimination of pronounced thick and thin locations. Also, it is clearly perceivable that fewer neps are present. Furthermore, the extremely limited development of fly in the ring spinning frame and the considerable decrease of yarn breakage or rupture is of considerable importance.
  • FIGURE 1 schematically illustrates a first phase or stage of the inventive process
  • FIGURE 2 schematically illustrates the end or terminal phase of the inventive process.
  • staple fiber slivers or bands for example formed of cotton, synthetic fibers and blends or mixtures, are removed from a number of cans 1 and combined, in known manner, into a fiber strand or arrangement 3 and drafted in a suitable drafting arrangement 4 into a highly parallelized web 5.
  • this web during passage through the apparatus 7 is soaked or impregnated with a fixing agent which is distributed as homogeneously as possible, said fixing agent will be more fully described hereinafter, and the introduction of which densed.
  • the part by weight of the fixing agent after subtracting the weight of the solvent is approximately 0.5 to 5%.
  • the still moist small sliver or band is then further compressed or condensed via a pair of calender rollers 11 into a compact sliver which approximately corresponds to a roving.
  • a pair of calender rollers 11 into a compact sliver which approximately corresponds to a roving.
  • the consistency of the band or sliver due to the fixing agent which is present is sumcient to insure that the small band or sliver upon passing through the funnel or trumpet wheel 12 is not impaired in any manner.
  • the band or sliver arrives at a can v13 placed therebeneath.
  • the fixing agent has already become inactivated or passified to such a degree that, the layers piled upon one another no longer stick together.
  • the fixed or set band or sliver possessing a smooth surface and which, in the meantime, has dried and exhibits an extreme breaking length of up to 1000 meters is now fed to the ring spinning frame 115, as best ascertained by reference to FIGURE 2.
  • the drafting occurs at the ring spinning frame itself, upon a single-zone drafting arrangement formed of two pairs of rollers 13 and 19, without the previously conventional preliminary draft or break achieved nowadays upon ring spinning frames provided with a preliminary drafting or break zone but with conventional or higher over-all or total drafts
  • the subsequent spinning by imparting twist and winding upon a ring spindle 20 or a pot spindle takes place in a conventional manner and terminates the second phase or stage of the process.
  • the requirements which are placed upon the fixing agent are the following:
  • connection or bond produced between the fibers should be capable of being easily broken in the drafting zone of the drafting arrangement, without the fiber cohesion resulting from the fixing agent being prematurely, destroyed in consequence of flexures and clamping during infeed of the bands or slivers.
  • the water soluble sizing agents previously employed up to the present in weaving mills or textile manufacturing processes generally come into consideration as fixing agents, whereby also an additional sizing with simultaneous reactivation of the already available size particles during the textile manufacturing process, if necessary, does not encounter any difliculty.
  • fixing agents well-known to the art as such type of sizing agents are corn starch, rice starch, and potato starch, which during preparation are dissolved in a concentration of 1 to 5% by cooking in water and cooled down to room temperature, or also applied in heated condition.
  • Noredux is produced by Blattmann & Co., of Wadenswil/ Zurich, Switzerland.
  • the fixing agents on the basis of pure starch give relatively brittle connections or bonds between the individual fibers, thereby resulting in a stiff band or silver, so that during unsuitable conditions of handling, for example with pronounced fiexing, this bond or connection easily breaks or ruptures already prior to drafting.
  • This disadvantage can be countered by the addition of plastieizing agents.
  • a polyvinyl alcohol as the fixing or sizing agent which, likewise to achieve a condition of use, is mixed in a concentration of approximately 1 to 5% in water.
  • Vibatex manufactured by the firm Ciba, of Basel, Switzerland has proven itself to be a suitable'polyvinyl alcohol.
  • the fixing or sizing agent a solution containing in combination starch and polyvinyl alcohol.
  • a surfactant or Wetting agent as for example Invadin IFC of the aforementioned Ciba Company, of Basel, Switzerland.
  • the addition of substances or additives commonly employed in the textile finishing or sizing department such as fungicides or bactericides, as for example Antimucin SR or Antimucin AN, a product of the Sandoz Company, of Basel, Switzerland, in a concentration of 0.01 to 0.02% in the same working operation with the fixing or sizing agent can be carried out, quite apart from the posisibility of dyeing the fibers by the addition of dyes or coloring matter in the fixing agent, more specifically, at a time during processing when the individual fibers can still be easier reached at all sides than with a finished twisted yarn. Furthermore, the addition of antistatic agents can easily and effectively take place at this time.
  • Process for the production of a spun yarn according to claim 1 including the step of subjecting the sliver to a drying operation after the step of condensing the web into a thin sliver possessing a small specific volume and smooth surface.
  • Process for the production of a spun yarn according to claim 1 including the step of introducing coloring matter at the same time when introducing the dissolved fixing agent into the web.
  • Process for the production of a spun yarn according to claim 1 including the step of simultaneously introducing substances selected from the group comprising wetting agents, fungicides, bactericides, and general textile finishing additives when introducing the dissolved fixing agent into the web.
