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- the yarn components are jointly withdrawn from the spinning means by a withdrawal system, and drawn before undergoing texturing.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 spinning means 1 includes a heated spin beam 2 , which mounts in side-by-side relationship a plurality of spinnerets 3 . 1 - 3 . 3 .
- 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 .
- the withdrawal means 10 is formed by a plurality of feed roll systems 14 . 1 - 14 . 6 which are associated to each of the yarn components 6 . 1 - 6 . 3 .

- the drives of the feed roll systems 14 . 1 - 14 . 3 are controllable independently of one another, so that it is possible to adjust a withdrawal speed that is adapted to the particular yarn component.
- the feed roll systems 14 . 1 - 14 . 3 are each followed by an additional feed roll system 14 . 4 - 14 . 6 .
- the yarn component 6 . 1 advances through feed roll systems 14 . 1 and 14 . 4
- the yarn component 6 . 2 through feed roll systems 14 . 2 and 14 . 5
- the yarn component 6 . 3 through feed roll systems 14 . 3 and 14 . 6 .
- the feed roll systems 14 . 4 - 14 . 6 are operated preferably likewise independently of one another by separate drive units. In the case that all yarn components 6 . 1 - 6 .
- the feed roll systems 14 . 4 - 14 . 6 can be activated preferably via a common control unit. In this case, it would also be possible to combine the individual drives of the feed roll systems 14 . 4 - 14 . 6 to a group drive. 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 pretreatment means 8 is formed by yarn lubrication units 7 . 1 - 7 . 3 associated to each of the yarn components 6 . 1 - 6 . 3 and subsequent entanglement nozzles 9 . 1 - 9 . 3 .
- a lubricant is applied to each of the yarn components 6 . 1 - 6 . 3 independently of the others.
- the filaments of the yarn components undergo an entanglement, each in its associated entanglement nozzle 9 . 1 - 9 . 3 . With that a yarn cohesion is essentially produced for the further treatment of the yarn components 6 . 1 - 6 . 3 .
- the further treatment of the yarn components 6 . 1 - 6 . 3 occurs downstream of the withdrawal means 10 in a texturing means 11 and an aftertreatment means 12 .
- the texturing means 11 is formed by a feed nozzle 15 and a stuffer box chamber 16 cooperating therewith.
- 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.

- An additional withdrawal godet 18 . 2 removes the composite yarn 21 from the combining means 19 and advances it to a takeup means 13 .
- the takeup means 13 winds the composite yarn 21 to a package 20 .
- the spinnerets 3 . 1 - 3 . 3 are used to spin three yarn components 6 . 1 - 6 . 3 in a parallel side-by-side relationship.

- FIG. 2 illustrates a further embodiment of a device according to the invention for carrying out the method of the invention.
- the embodiment is essentially identical to the foregoing embodiment, so that the foregoing description is herewith incorporated by reference and that only differences are described. Components having identical functions have been provided with identical numerals.

- After separately texturing the yarn components 16 . 1 - 16 . 3 same are jointly removed from the respective yarn plugs by withdrawal godet 18 . 1 and advanced to the combining means 19 for forming the composite yarn 21 .
- the withdrawal means of the embodiments shown in FIGS. 1 and 2 are exemplary in their arrangement and construction. Thus, it is possible to combine the withdrawal means in the illustrated embodiments in any way to realize a draw ratio that is adapted to the yarn components.
- FIG. 3 illustrates a further embodiment of a withdrawal means, as could be used, for example, in the device of FIG. 1 or 2 .
- the feed roll systems 14 . 1 and 14 . 3 are associated to the yarn component 6 . 1
- the yarn components 6 . 2 and 6 . 3 advance together over the feed roll systems 14 . 2 and 14 . 4 . It is thus possible to advance and draw the yarn component 6 . 1 independently of the yarn components 6 . 2 and 6 . 3 .
- the yarn components 6 . 2 and 6 . 3 are jointly advanced and drawn by the feed roll systems 14 . 2 and 14 . 4 .

- each of the treatment means and units arranged in the path of the yarn components 6 . 1 - 6 . 2 is independently and separately controllable to enable an individual treatment of the yarn components 6 . 1 and 6 . 2 .
- the yarn components 6 . 1 and 6 . 2 form yarns 21 . 1 and 21 . 2 which are wound at an identical winding speed to the packages 20 . 1 and 20 . 2 .
- An arrangement of this type is particularly suited for producing different yarns 21 . 1 , 21 . 2 within a spinning apparatus. When spinning the yarns, it is then possible to take into account in particular individually adjusted withdrawal speeds and draw ratios.
- the described embodiments for carrying out the method of the invention are exemplary in their arrangement and selection of the treatment units. Additional pretreatment or aftertreatment steps and means may be introduced to be able to perform, for example, additional treatments on the yarn components before or after texturing them, or to carry out additional treatments on the composite yarn. Likewise, the type and the construction of the texturing means is exemplary. To adjust defined crimps, the yarn components may also be textured, each with different parameters. In the case of separate texturing, it is also possible to apply different texturing methods. The separate adjustment of the draw parameters on the yarn components provides a high flexibility in the production of textured composite yarns.
- the configuration of the feed roll system in the illustrated embodiments is exemplary. It would thus be possible to construct all or part of the feed roll systems with respectively two driven godets. Both godets of a feed roll system could be operated at the same or different circumferential speeds. In addition, one or both godets of a feed roll system could include heating means to be able to perform a thermal treatment on the yarns.
