Definitions

  • the present invention relates to a device and a method for producing a multicolored yarn from differently colored filaments, each consisting of a large number of continuous filaments, with at least two filaments being guided into a drawing device, where they are guided by a pair of infeed rollers to at least two pairs of drafting system rollers and stretched by them, which are followed by a texturing device with a cooling drum, according to the preamble of claim 1.
  • colored yarns are produced by mixing several bundles of threads of different colors.
  • the individual endless filaments In order to create a clear color effect on the end product, the individual endless filaments must be connected to one another in such a way that a clear color separation can be seen. This is usually done by tangles, in which the threads are intertwined by applying compressed air from the side. The crimping then takes place in the stuffer box of a texturing nozzle.
  • the EP 0784109 B1 describes a method for producing a yarn with a plurality of differently colored filament bundles. At least one bundle of filaments is treated individually above the joining step and below all previous stretching and texturing processes.
  • the object of the invention is the further development of a known device and a method with the aim of simplifying the device and the method for producing the multicolored yarns and producing an end product with a clear color effect.
  • the invention includes the technical teaching that to produce a multicolored yarn from differently colored filaments consisting of a large number of continuous filaments, at least two filaments are guided into a drawing device, where they are guided by a pair of infeed rollers to at least two pairs of drafting system rollers and are stretched by these, which is followed by a texturing device with a cooling drum.
  • the invention is characterized in that a nozzle for knotting the filaments, which consist of a large number of continuous filaments, is arranged in front of the texturing device. Each filament is knotted separately in the nozzle. The filaments converge into a yarn in the texturing nozzle. Contrary to the general opinion of those skilled in the art, it has surprisingly been shown that sticking and bonding of the filaments during subsequent texturing can be prevented due to the short residence time in the nozzle, so that very high color clarity can be achieved.
  • the nozzle for knotting the filaments is arranged after the two-stage stretching and before the texturing nozzle.
  • the pair of drafting rollers in front of the nozzle has the highest speed in the drafting device, with which the filaments are conveyed. This allows a minimum residence time in the nozzle to be achieved, which prevents the colors from mixing due to the possible bonding of the filaments with each other.
  • the speed of the filaments on these drafting system rollers is at least 1,700 m/min.
  • the drafting system rollers are designed as heated duo rollers.
  • the filaments which consist of a large number of continuous filaments, are each knotted separately by means of a nozzle before being stretched. This first knotting can further improve the subsequent process of the second knotting, since it stabilizes the structure of the individual filaments.
  • the nozzles for turbulence and knotting can be operated at a pressure (overpressure) of 0.01 to 12 bar, with a gaseous medium, preferably air, being introduced laterally into the nozzle and causing the filaments to be turbulent or knotted.
  • a pressure overpressure
  • a gaseous medium preferably air
  • the nozzle is arranged after the pair of infeed rollers and before the drafting system rollers for knotting the filaments. According to the prevailing opinion, subsequent stretching and texturing would reduce the color clarity of the yarn, since the individual filaments can stick together as the process progresses. A very short dwell time of the filaments in the nozzle prevented subsequent sticking and bonding of the filaments, so that the desired color clarity also comes to light.
  • drafting system rollers are used after the texturing device, which cool the yarn to a temperature of 0°C to 80°C, preferably to a temperature of 0°C to 50°C. This is advantageous for the further fixation of the yarn that has been compressed in the texturing nozzle, but the color clarity also comes into its own before the yarn is wound on the winder.
  • the method according to the invention according to claim 9 solves the problem in that at least two filaments are guided into a stretching device, guided there by a pair of infeed rollers to at least two pairs of drafting system rollers and stretched by them, then textured and cooled on a cooling drum (9). .
  • the method according to the invention is characterized in that the filaments, which consist of a large number of continuous filaments, are each knotted separately before texturing. The subsequent convergence of the filaments into a yarn takes place in the texturing nozzle.
  • the filaments are entangled to form a yarn after two-stage stretching in the texturing nozzle. Since the speed of the filaments in the drafting device is highest on the second pair of drafting rollers, the short dwell time in the nozzle, in which the filaments are knotted separately, means that the filaments do not mix with each other or partially fuse during the subsequent texturing, which means that the color clarity of the yarn is improved.
  • the speed of the filaments is at least 1,700 m/min.
  • the effect is preferably intensified if the filaments, which consist of a large number of individual filaments, are knotted separately before stretching. As a result, each knotted filament has a more stable structure, which has a better effect on color clarity during subsequent texturing and swirling.
  • the filaments are knotted before stretching.
  • the short dwell time in the nozzle means that the filaments do not tend to stick together during further processing in the texturing nozzle.
  • the yarn is preferably stretched or relaxed by drafting rollers, which cool the yarn to a temperature of 0°C to 80°C, preferably to a temperature of 0°C to 50°C.
  • the yarn that is puffed up in the texturing nozzle can thus be set very well without reducing the color clarity.
  • FIG 1 shows a section of a spinning-drawing system according to a first exemplary embodiment, in which six differently colored filaments F1-F6, for example made of polyamide 6 (PA6), run into the drawing device 1 from spinnerets (not shown).
  • F1-F6 for example made of polyamide 6 (PA6)
  • FIG. 1 shows a section of a spinning-drawing system according to a first exemplary embodiment, in which six differently colored filaments F1-F6, for example made of polyamide 6 (PA6), run into the drawing device 1 from spinnerets (not shown).
  • Filaments F1 - F6 are colored using different batches of plastics, which are extruded separately and converted into endless filaments using a spinning head.
  • Each filament F1 - F6 consists of up to 1000 continuous filaments, which are combined below the spinning head in front of the stretching device 1 to form one filament F1 - F6 each.
  • a first nozzle 4 can optionally be arranged between the pair of inlet rollers 3.1, 3.2 and the pair of stretching rollers 5.1, 5.2, in which the six filaments F1-F6 are laterally subjected to a gaseous medium, preferably air, with a pressure of 0.01-12 bar .
  • the nozzle 4 has a separate guide for each filament F1-F6, so that the filaments F1-F6 do not come into contact with one another. Up to 1000 endless filaments are knotted together within the guide of the nozzle 4, so that six separately knotted filaments F1-F6 exit the nozzle 4 and are guided onto the drafting system roller pair 5.1, 5.2.
  • the filaments F1-F6 are heated to a temperature of 65° C. at a speed of 925 m/min.
  • This pair of drafting system rollers 5.1, 5.2 is designed as a mono-roller, in which only the drafting system roller 5.1 is driven.
  • the drafting system roller 5.2 is not driven, but rotates with the tension of the filaments F1-F6.
  • the drafting system rollers 5.1, 5.2 can also be designed as duo rollers in which both rollers are driven and which essentially have the same outside diameter. This has the advantage that the gradual heating of the filaments F1 - F6 can take place more continuously over a longer period of time, which is advantageous for the transformation of the molecular chains.
  • the surfaces of the pairs of drafting rollers can be heated via a heating system (not shown), for example an electrical, steam-based or liquid-based heating system, it being assumed below that the filaments F1 - F6 during at least two turns around the drafting roller pairs also have assumed the temperature of the pairs of stretching rollers.
  • a heating system for example an electrical, steam-based or liquid-based heating system, it being assumed below that the filaments F1 - F6 during at least two turns around the drafting roller pairs also have assumed the temperature of the pairs of stretching rollers.
  • the filaments F1 - F6 are guided from the pair of stretching rollers 5.1, 5.2 to the pair of stretching rollers 6.1, 6.2, having first passed them through a guide 14 be kept at a distance from each other. Further stretching and heating on the pair of stretching rollers 6.1, 6.2, which are designed as a duo, takes place at a speed of 2,500 m/min and heating to 170°C.
  • the nozzle 7 also has a separate guide for each filament F1-F6, so that the filaments F1-F6 do not come into contact with one another. Up to 1000 continuous filaments are knotted together within the guide of the nozzle 7, so that six separately knotted filaments F1-F6 exit the nozzle 7 and enter the texturing nozzle. In the nozzle 7, the six filaments F1-F6 are knotted by an injected gaseous medium, preferably air, at a pressure of 0.01-12 bar.
  • Yarns G1, G2 are formed in the texturing nozzle 8, with a total of two crimped yarns G1, G2 being produced in the texturing nozzle 8, each consisting of three filaments F1-F3 and F4-F6, each with one color per filament.
  • each yarn G1, G2 can have three filaments with three different colors that are clearly distinguishable from each other.
  • each yarn G1, G2 can also consist of two or four filaments of different colors.
  • the advantage of the invention is that the yarn G1, G2 with the three filaments clearly displays the colors of the filaments without any intermingling. According to the state of the art, this would not be possible since the individual filaments F1-F3 and F4-F6 would stick together, which would lead to an unclear differentiation of the colors. In contrast to the prior art, it has surprisingly been shown that with an extremely short dwell time within the nozzle 7, the subsequent sticking of the filaments F1-F3 and F4-F6 in the texturing nozzle can be prevented. Since the speed of the filaments F1-F6 in the entire drafting device 1 is highest at the drafting rollers 6.1 and 6.2 is, at the same time the dwell time of the filaments F1 - F6 in the downstream nozzle 7 is the shortest. The dwell time of the filaments F1-F6 at a speed of the filaments F1-F6 around the drafting rollers 6.1 and 6.2 of 2,500 m/min with PA6 in the nozzle 7 is only around 5 milliseconds.
  • the parameters for the drafting system rollers 6.1, 6.2 can look like this, for example: parameters for Unit pp PA6 PET PA6-6 drafting rollers 6.1,6.2 speed m/min 2030 2500 3200 2960 temperature °C 130 170 165 200
  • the filaments F1-F6 run into the downstream texturing nozzle 8, in which they converge to form the yarn G1 and G2, which means that the texturing nozzle 8 only has to have two nozzle channels.
  • the structure of which is frozen on the subsequent cooling drum 9.
  • the filaments F1 - F6 are thus heated again in the texturing nozzle 8 after the nozzle 7, with PA6 from 170°C to 180°C.
  • a subsequent slight stretching takes place with cold drafting rollers 10.1, 10.2 and 11.1, 11.2.
  • the speed of the yarn on the drafting system roller 10.1 is 2,222 m/min.
  • the drafting roller 11.1 transports the yarn G1, G2 with a Speed of 2,257 m/min at a temperature of, for example, 20°C to 80°C.
  • the drafting system rollers 10.1, 10.2, 11.1, 11.2 can preferably be cooled.
  • the yarn G1, G2 is wound onto two spools at a speed of 2201 m/min.
  • the advantage of this system is that an existing system with six or up to twelve incoming filaments only requires one texturing nozzle 8 with two or up to four channels, so that the drafting with the drafting system rollers 10.1, 10.2, 11.1, 11.2 is shorter can be built.
  • the nozzle 4 can be used optionally.
  • the process for knotting the filaments F1 - F6 separately in the nozzle 7 and combining them into the yarns G1, G2 in the texturing nozzle 8 can also be carried out without the nozzle 4 ( figure 3 ) can be used and gives good results.
  • the use of the nozzle 4 for knotting the individual filaments F1 - F6 has the advantage that the structure of each individual filament F1 - F6 is more stable, which has a positive effect on the subsequent knotting in the nozzle 7 . With the nozzle 4, which causes a knotting of up to 1000 endless filaments of each filament F1 - F6, the color separation after the knotting in the nozzle 7 becomes even clearer.
  • the six filaments F1-F6 are knotted separately by using the nozzle 4 between the pair of inlet rollers 3.1, 3.2 and the drafting system rollers 5.1, 5.2. Due to the short residence time of the filaments F1-F6 in the nozzle 4, a separate knotting can take place, so that a clear color separation is also achieved in the yarns G1, G2 subsequently produced in the texturing nozzle 8 from the six filaments F1-F6.
  • the further processing of the filaments F1 - F6 takes place as in the exemplary embodiment 1, but without the nozzle 7.
  • the advantage of this configuration is that the separately knotted filaments F1 - F6 can be guided more easily and more stably from the nozzle 4 through the entire system.
