- Yarns result different cores, whereby also the jacket materials with multiple execution of jacket material sources can be different.
- the materials are arranged in the fiber cross section may be that there is no completely enclosed core.
- FIGS. 1 e and 1 f The material flow scheme in Fig. 1 e corresponds 1 g and 1 h, in the exemplary embodiment a first material 10 c for yarn coats and a second material 10 a for another group of Yarn jackets is supplied, each in recesses 12 c, or 12 a. Further a core material 10 b that is the same for all yarns is introduced into a depression 12 b, from where this material is distributed over the entire length of the distribution system 1 can penetrate into individual core bores 21 a of a distributor plate 2.
- FIG. 1 e It applies to a concept according to FIG. 1 e as well as to the concepts already described so far, that the different materials from different sources 14 to 16, 14 'to 16 'and 14 "to 16" originate.
- the entry-side slots 12 a, 12 b, 12 c each go into outlet-side long slots 13, 13 ', 13 ", which are equipped with the different bores, thus jacket bores 21 c, or core bores 21 a, communicate.
- Fig. 1 e it can also be seen that, as by dashed lines in the lower Part shown in the perforated plate 2, a connection of the various mentioned There are bores to the core capillaries 25 a, or jacket capillaries 25 c.
- the systems of bores for the core material, or jacket material, and of capillaries 21, 25 are, as indicated schematically, in preferably separate ones Groups summarized.
- a hole pattern of capillaries with three core capillaries and three jacket capillaries indicated in the periphery in one group can be grouped as shown below left, while another Group of bores, or capillaries, see in the nozzle plate 2 in right part shown schematically, with four core holes and six jacket holes in an exemplary embodiment, in a second group according to the right Block of holes in the perforated plate 2, be summarized.
- a perforated plate 2 can of course also be divided into several sections, such as by the dashed line in the middle of the perforated plate 2 between the hole groups 21, 25, respectively 21 ', 25' is indicated.
- FIG. 1 f A similar representation can be found in FIG. 1 f, with only a single jacket material 10 b through openings 12 b, or slots 13 ", over the entire width of a Distribution system 1, or a hole system 3, is distributed.
- This coat material passes through jacket bores 21 a, b in jacket capillaries 25 c in the Perforated plate 2.
- core material 10 a, 10 c Sources 14 to 16, or 14 'to 16' which are only available to a limited extent according to the representation of the staggered openings 12 c, 13 ', respectively 12 a, 13, can spread over certain areas of the distribution system.
- n materials from n sources there are basically no limits.
- the different Materials are not concentric with each other in the finished yarn, what means that the core and jacket holes named according to the definition are not so need to be positioned that each core holes in the inner area and jacket holes lie in the outer area.
- a multi-component yarn can also do so be designed so that the so-called core bores near the escape of the spinnerets 32 lie next to so-called laterally more distant casing bores, so that practically no concentric enclosure of the core components by jacket components given is.
- the different variants described can be (For example, tricolor machine) can be realized in which the tricolor spinnerets to be replaced by multi-component spinnerets.
- a multi-color machine can can be upgraded to a multi-component machine.
- a Three-color machine can be converted to a two-component machine. The conversion consists only in that the spin pack, consisting of, for example a distribution system 1, a perforated plate system 2 and a spinning plate system 3 is composed as described above.
- So yarns can are produced in which, for example, the core consists of undyed polymer or the jacket consists of different colored polymers or different types Polymers form the core.
- extruders with metering devices for coloring the are preferred Melt equipped. But there can also be different numbers of extruders available. In conventional multi-color machines it is common to have three different-colored machines To lead melt streams in melt lines to the spinning beam, where a further division takes place before the feeding in spinnerets. The different, colored melts are conducted separately, so that they are in locally separated Areas to reach the spinnerets.
- the spinnerets of multicolor spinning machines are now according to the invention replaced by spinnerets for multi-component yarns. From every capillary opening a multi-component filament can emerge as described. Through the Combination of components of multi-color machines and components of Machines for the production of filaments from several material components can Any combinations and thus yarn types are produced in one and the same spinning package become.
- shell material can be used on the remaining two extruders processed with different color additives (masterbatch). Then it will Bicomponent bicolor yarn spun.
- the core share is approx. 33% and the coat share 33% of each color, for a total of approx. 67%. These shares can each can be varied as required according to machine design.
- multicomponent yarns (core / sheath) are also produced, in which only the Coat or the core is colored.
- the coloring is usually carried out by adding dye in spinning (spin dyeing) or in the finished yarn or carpet (Yarn dyeing, printing, piece dyeing).
- spin dyeing or in the finished yarn or carpet
- Yaarn dyeing, printing, piece dyeing The dyeing process is then complete, when the dye is completely and evenly distributed in the yarn.
- the cost of Dye can be the same amount as the polymer costs. If it succeeds, to produce the dye with a device or system described according to the invention, a significant cost reduction can be achieved.
- the savings options can be structured as follows:
- the dyeing of a thin coat layer of the filament can be enough to color the yarn alone. If only the sheath is made from a polymer to which an additive (masterbatch) has been added during the spin dyeing of core-sheath yarn, half of the dye can be saved with a core / sheath ratio of 50:50. This means a reduction in raw material costs of approx. 12 to 25%.
- the spin dyeing of core material can Coloring done. If only the core is spun out of core-jacket yarn a polymer that is mixed with masterbatch can with a core / shell ratio by 50:50 half of the dye can be saved. That means a reduction in raw material costs of approx. 12 to 25%.
- core-sheath yarn in piece dyeing enables the use of sheath polymer with only color affinity for a certain class of dyes. So that can be achieved be that the dye only builds up in the coat and thus the required amount of dye is reduced.
- antistatic yarns can be made by using the agents achieve significant cost reductions according to the last (fourth) aspect of the invention.
- it can use antistatic material in the manufacture of yarns different shells only in part of the different sheath components be used so that the antistatic properties while saving material of the antistatic material are nevertheless given.

Wird beim Spinnfärben von Kern-Mantel-Garn nur der Mantel aus einem Polymer hergestellt, das mit einem Zusatzstoff (Masterbatch) versetzt ist, kann bei einem Kern-/Mantelverhältnis von 50:50 die Hälfte des Farbstoffes gespart werden. Das bedeutet eine Reduktion der Rohmaterialkosten von ca. 12 bis 25 %.
