Definitions

  • the invention relates to a method and apparatus for continuous spinning of fibrous textile materials. More particularly, the invention relates to a method and apparatus of the type utilizing a rotary spinning chamber.
  • the greatest shortcoming of the spun yarn obtained by this spinning method is that its strength (tensile strength) is inferior by 15- 25% than the spun yarn obtained by the ring-traveller spinning technique, although it is superior with respect to the latter in its bulkiness and uniformity.
  • This shortcoming is ascribable to such facts as that the yarn spun by this method is bulky, the fiber parallelism thereof is irregular, its proportion of curved and looped fibers is great, etc.
  • the problem for which solution has been demanded all along is that of raising the strength of this spun yarn to an extent as to make it comparable to that of the conventional ring-spun yarn.
  • the present invention has been directed to the elimination of the aforesaid shortcoming and has achieved this by feeding at least two ends of staple fibers to the rotary spinning chamber, to one of which staple fibers only twist and draft are imparted, and thereafter combining this with the other staple fibers to obtain a single end of spun yarn. That is to say, the strength of the spun yarn obtained has been increased by increasing the proportion occupied by those fibers which are aligned axially of the running yarn.
  • the feature of the present invention resides in feeding two or more ends of staple fibers to a single rotary spinning chamber, imparting only a draft and twist to at least one of the ends of staple fibers without breaking it in the rotary spinning chamber, and thereafter combining these two or more ends of staple fibers followed by taking up the resulting composite yarn from the rotary spinning chamber and winding it up.
  • An object of the present invention is to provide a spinning method and apparatus by which spun yarn having great parallelism of the fibers can be obtained by means of the method utilizing a rotary spinning chamber.
  • Another object of the invention is to provide a variety of composite yarns by adjusting, as desired, the speed at which the yarn is taken up from the rotary spinning chamber and wound.
  • a further object of the invention is to provide a composite yarn of great strength and bulkiness by substituting a filament yarn for at least one of the staple fibers.
  • FIGS. 1 and 2 are vertical sectional views illustrating the principal parts of the invention apparatus, a mode being shown of making a spun yarn in which the two ends of fibrous material fed are of the same staple fiber, FIG. 3 being a plan view of FIG. 2; FIG. 4 illustrates a mode of making a covered yarn (core yarn) with the apparatus shown in FIG. 1; and FIG. 5 is a vertical sectional view of an apparatus similar to the embodiment shown in FIG. 1 a spinning mode of a core-incorporated coiling yarn being shown.
  • fibrous materials that are to be broken may be fed directly from an opening roller.
  • Reference numeral 1 designates the funnel-shaped spinning chamber capable of high speed rotation disposed between the feed rollers 2 and take-up rollers 3 and having a fiber collecting surface at its inner peripheral wall.
  • a stationary cap 5 covers the fiber inlet side of the spinning chamber 1.
  • Numeral 6 designates a stationary supply tube whose inlet side 7 is positioned adjacent to the feed rollers 2 while its outlet side 8 faces the fiber collecting surface 4 of spinning chamber 1.
  • Numeral 9 designates a guide pipe which passes through the cap 5 in approximately its middle part, 10 is a discharge opening of the spinning chamber 1 and 11 is a cross winding mechanism for winding in cheese form yarn 12 leaving the take-up rollers 3.
  • fibrous materials (coarse yarn or sliver), two ends of which make up a set, are delivered as two ends of staple fibers or fiber ribbon fleeces S S from feed rollers 2, spaced with a suitable interval H, via a conventional drafting mechanism (not shown), to a single rotary spinning chamber 1.
  • the peripheral wall of the fiber collecting surface 4 of rotary spinning chamber 1 is provided with numerous perforations 13, and either by the high speed rotation of the rotary spinning chamber 1 or by the addition suitably of a suction means (not shown), reduced pressure is set up inside the rotary spinning chamber 1, with the consequence that an air current in the direction of arrow (a) is set up in the stationary supply tube 6 to result in breaking the fiber ribbon fleece S which has been delivered into the stationary supply tube 6, followed by conveying and adhering the fibers to the fiber collecting surface 4 of rotary spinning chamber 1 and thereafter twisting the fibers while withdrawing the fibers by means of the pair of take-up rollers 3 via the discharge opening of rotary spinning chamber 1.
  • the fiber ribbon fleece S the other end is fed to the guide pipe 9 provided in approximately the middle of the stationary cap 5, which covers the fiber inlet side of the funnel-shaped rotary spinning chamber 1.
  • Fiber ribbon fleece S which has passed through the guide pipe 9, is directly delivered to twisting point 14 of the aforementioned fiber ribbon fleece S or in the vicinity thereof, without being made to adhere to the fiber collecting surface 4 of rotary spinning chamber 1, at which point it is caused to be drawn into the twisting action of the aforesaid fiber ribbon fleece S following which the two fleeces S S are combined at the inclined surface 15 of rotary spinning chamber 1, thus obtaining a twisted yarn 12.
  • the rotary spinning chamber 1 is placed inside a box frame 20.
  • Box frame 20 is provided with a suction hole 21 which is in communication with a suitable suction means (not shown), whereby the inside of said box frame is reduced to below atmospheric pressure and at the same time the pressure inside the rotary spinning chamber is also reduced to below atmospheric pressure by means of the perforations 13 of the rotary spinning chamber 1.
  • This embodiment is provided with a straight inclined stationary supply tube 6 for pneumatically conveying the fleece S delivered from the feed rollers 2 to the fiber collecting surface 4 of rotary spinning chamber 1, thus permitting the smooth conveyance of the fiber, but otherwise functions practically in the same manner as the embodiment illustrated in FIG. 1, two ends of fiber ribbon fleeces S S being made into a single end of twisted yarn in the same fashion.
  • the structure of the yarn made by combining the two ends of fleeces S S thus varies depending upon the peripheral speeds of the feed rollers 2 and the take-up rollers 3, a choice of the ratio between the rollers may be made in accordance with what is desirable depending upon the use to which the product is to be put.
  • the common spun yarn can be obtained when the peripheral speed of the take-up rollers 3 is operated at a slightly lower speed than that of the feed rollers 2.
  • FIGS. 4 and 5 are illustrated modes wherein, of the two ends of fibrous materials to 'be fed, one endis a ribbon fleece S composed staple fibers, whereas the other end is a synthetic multifilament S and the two ends are combined as hereinbefore described, to obtain yarns having the synthetic multifilament yarn as a core about which the staple fiber fleece S is wrapped or wrapped and covered.
  • the fibrous material composed of staple fibers is fed to the stationary supply tube 6, while the fibrous material of synthetic multifilament yarn is fed to the guide pipe 9.
  • a single end of covering yarn or core-incorporated coiling yarn can be made in a single step.
  • a method of preparing a single twisted end of yarn comprising the steps of feeding a first end of staple fibers into a spinning chamber and directing the first fiber end against a fiber collecting surface in the chamber; drawing the first fiber end from the chamber to twist the first fiber end and define a twisting point spaced from the fiber collecting surface; feeding a second end of staple fibers directly to the twisting point; twisting the first and second fiber ends together into a single twisted end of yarn; and taking up the single twisted end of yarn.
  • Spinning apparatus for forming a single twisted end of yarn comprising feed means for feeding first and second ends of staple fibers; take-up means; a funnel-shaped spinning chamber having an inlet, an outlet and an inner fiber collecting surface, said chamber being disposed between said feed means and said take-up means to receive said first and second fiber ends from said feed means at said inlet and deliver a single twisted end of yarn through said outlet to said takeup means; a stationary cap covering said inlet of said chamber; a stationary supply tube supported by said cap for receiving said first fiber end and directing said first fiber end against said-.fiber collecting surface, said first fiber end being drawn along said fiber collecting surface and being twisted by the spinning of said chamber at a twisting point spaced from said fiber collecting surface; and a guide pipe extending through the center of said cap for receiving said second fiber end, said guide pipe having an outlet spaced from said chamber outlet to deliver said second fiber end to said twisting point whereby said first and second fiber ends are combined to form a single twisted end of yarn at said chamber outlet.
