Definitions

  • the invention relates to a method for spinning and texturing a multifilament composite yarn as well as an apparatus for carrying out the method.
  • a plurality of yarn components are initially spun from a thermoplastic melt by a spinning means, then cooled, and separately pretreated in parallel side-by-side relationship.
  • the yarn components are jointly withdrawn from the spinning means by a withdrawal system, and drawn before undergoing texturing.
  • the component yarns For texturing the component yarns, the latter are textured jointly or parallel in side-by-side relationship and subsequently combined to form a composite yarn.
  • the known method is directed to changing the appearance of the composite yarn by a separate compacting step, essentially by separately entangling or separately texturing the differently dyed yarn components.
  • visual properties represent only a part of the properties of the yarn which are desired for further processing.
  • the physical properties such as strength and elongation take priority over visual properties.
  • the known method and the known apparatus play only a subordinate role in the production of qualitatively superior composite yarns.
  • a further object of the invention is to provide a method and an apparatus, which permit treating parallel spun yarn components or yarns with greatest flexibility until they are wound.
  • the invention is based on the knowledge that after spinning, yarn components that are parallel spun from a basic polymer, may have an individual molecular structure as a result of adding different additives, for example, different dyes. When advancing and drawing the yarn components jointly, this individual molecular structure will lead to different physical properties, in particular different strengths. This is where the invention comes into play, in that at least one of the yarn components is drawn separately and independently of the other yarn components before being textured. It was thus found that in the production of a composite yarn from an individual polypropylene yarn that had been dyed blue, and a second undyed polypropylene yarn, different draw ratios lead to respectively maximum strengths with simultaneously the least residual elongations in the yarn components.
  • the blue dyed yarn component required a draw ratio of 1:2.5, and the undyed yarn component required drawing at the ratio of 1:3.5.
  • the invention permits the purposeful influencing of the physical properties of the yarn components in a manner that it is possible to produce a composite yarn of maximum strength, while having simultaneously a minimal residual elongation.
  • an advantageous further development proposes to withdraw a yarn component during spinning separately and independently of the other yarn components at a withdrawal speed that differs from the withdrawal speeds of the other yarn components.
  • the latter is formed preferably by entangling or texturing the yarn components.
  • the choice in which way the yarn components are combined to the composite yarn is essentially determined by the desired visual properties of the composite yarn. For example, to obtain in the case of a multicolor yarn a distinct, accentuated mixed color, it is preferred to produce the composite yarn after separately texturing the yarn components by entangling.
  • a withdrawal system which is formed by a plurality of feed roll systems, with at least one feed roll system being associated to one of the yarn components.
  • the yarn component being drawn by the one feed roll system is thus drawn separately and independently of the other yarn components.
  • the feed roll system associated to the one yarn component is made for separate operation and control, so that an individual adjustment is possible for withdrawing and drawing the yarn component.
  • the feed roll systems can be operated or controlled individually or in groups.
  • the texturing means is formed preferably by a feed nozzle and a stuffer box chamber cooperating with the feed nozzle.
  • the feed nozzle is preferably operated with a hot conveying medium, so that the yarn components or the formed yarn plug undergo a thermal treatment at the same time.
  • a cooling unit is provided which cools the yarn plugs by means of a cooling medium.
  • the method and the apparatus of the invention are also suited for producing a composite yarn, whose yarn components are spun from different polymers.
  • the composite yarn is produced from feed yarn packages
  • FIG. 1 is a schematic view of a first embodiment of the apparatus according to the invention.
  • FIG. 2 is a schematic view of a second embodiment of the apparatus according to the invention.
  • FIGS. 3 and 4 are schematic views of some embodiments of a withdrawal means of the apparatus according to the invention.
  • FIG. 5 is a schematic view of a further embodiment of an apparatus for carrying out the method of the invention.
  • the apparatus as shown in FIG. 1 comprises a spinning means 1 that connects to one or more melt producers (not shown).

  • the spinnerets 3 . 1 - 3 . 3 each comprise on their underside a plurality of spin holes, through which a polymer melt which is supplied to each of the spinnerets 3 . 1 - 3 . 3 flows.
  • the melt is thus extruded under pressure to form a plurality of groups of individual filaments.
  • a cooling shaft 4 Downstream of the spin beam 2 , a cooling shaft 4 is provided, through which the groups of extruded filaments advance, so that the filaments emerging at approximately the melt point are cooled.
  • the cooling shaft 4 could connect, for example, to an air flow system, which blows cooling air substantially transversely toward the filaments.
  • the filament groups associated to respective spinnerets 3 . 1 - 3 . 3 are combined to form a yarn component 6 . 1 - 6 . 3 by yarn guides 5 . 1 - 5 . 3 at the outlet of the cooling shaft 4 .
  • a withdrawal means 10 Downstream of the spinning means 1 is a withdrawal means 10 for withdrawing the yarn components 6 . 1 - 6 . 3 from the spinnerets 3 . 1 - 3 . 3 .

In the cases, in which the withdrawal means 10 removes the yarn components 6 . 1 - 6 . 3 at different yarn speeds, for example, to realize visual effects on a composite yarn, the drives of the feed roll systems 14 . 4 - 14 . 6 are separately operated and controlled.

  • the feed nozzle 15 connects to a source of pressure, which supplies a conveying medium to the feed nozzle 15 .
  • the conveying medium draws the yarn components 6 . 1 - 6 . 3 into the feed nozzle 15 and subsequently compresses them to a yarn plug in the stuffer box chamber 16 . This causes the yarn components 6 . 1 - 6 . 3 to intermingle in part.
