Definitions

  • the invention relates to a method for co-spinning synthetic threads, made of at least two polymers on a double spinning position consisting of at least two spinning positions arranged next to one another, and a device for carrying out this method.
  • US Pat. No. 4,025,595 relates to a process for producing mixed filaments with 20 to 68 fibrils and a titer between 70 and 260 den, wherein at least two fiber bundles are co-spun, swirled separately, stretched together and then at a degree of swirling between 45 and swirled 80%. According to this method, fully drawn threads are produced on a double spinning position.
  • the disadvantages of this process are: firstly, the low productivity, since one only works with a spinning take-off of 800 m / min, and secondly, that only one yarn is produced in a double spinning position.
  • the invention has for its object to provide a method that allows higher productivity with less financial effort per spinning station.
  • the object is achieved according to the invention in that a polymer A is spun in a first spinning position and a polymer B in a second spinning position to at least two partial threads, each of the partial threads is subjected to a separate treatment, a partial thread of the two spinning positions is combined in a union point and the resulting ones Threads are wound up.
  • spun yarns are produced without drawing before winding.
  • the fast spun thread is partially drawn and, if used for texturing, must be textured for drawing.
  • a partially drawn yarn has better properties for texturing than a fully drawn yarn.
  • the yarn according to the invention can also be used as a smooth or drawn yarn.
  • spinneret with a semicircular arrangement for the capillaries.
  • four to eight partial threads are produced per spinning position.
  • two to four spinnerets are used, which are arranged side by side, i. H. the four, six or eight spinnerets on the same line, or the spinnerets of one spinning position on a line offset from the spinning nozzles of the other spinning position.
  • titer of the final thread is not critical, threads with a final titer between 50 and 600 dtex, preferably between 50 and 260 dtex, are produced.
  • the titer of the individual filaments is also not critical.
  • the threads obtained are LOY (Low Oriented Yarn) or POY (Partially Oriented Yarn), preferably POY, with a winding speed between 2500 and 6000 m / min.
  • the partial threads are preferably wound on two winding devices.
  • polyester is understood to mean polyester produced either by direct condensation of ethylene glycol and terephthalic acid or by transesterification of dimethyl terephthalate with ethylene glycol and subsequent polycondensation of the diglycol terephthalate initially formed.
  • diols such as 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol or cyclohexane-dimethanol, and in addition to terephthalic acid or. of the dimethyl terephthalate still other dicarboxylic acids such as isophthalic acid, adipic acid, azelaic acid, dimer fatty acid or. the alkyl esters of these acids can also be used.
  • polyester-polyester polyamide-polyamide, polypropylene-polypropylene and polyamide-polyester, polyamide-polypropylene, polyester-polypropylene combinations can be considered as synthetic polymers of the partial threads. Combinations can also be selected in which there is a certain shrinkage difference between the two threads.
  • master threads for spun-like threads it is also possible to produce master threads for spun-like threads.
  • modified, i.e. H. regular and basic dyeable polyester contains a metal sulfonate such as the sulfonate of 3,5-isophthalic acid or the sulfonate of 3,5-isophthalic acid dimethyl ester.
  • a modified, basic dyeable polyester it additionally contains a polyalkylene glycol or a polyolefin, as described in the international application PCT / CH83 / 00035.
  • the spun-like thread according to EP patent 22 065 can also be produced according to the present invention.
  • a spinning position then contains spinnerets with fine and coarser capillaries.
  • This partial thread forms the sheathing component and that of the other spinning position the core component.
  • the titer-related stretching force ratio of the partial threads made of different polymers is one Reference stretch between 1: 1.2 and 1: 2 greater than 2.
  • the clamping length in the blow shaft can be varied separately when treating the partial threads made of different polymers.
  • the blown air temperature, the blown air pressure and the blown air humidity are known to be set and, like the spin preparation type and application amount, can also be varied separately.
  • the invention further relates to a device for performing the method, characterized in that the spinning position for the polymer (A) is assigned a metering pump and at least one spinneret each and the spinning position for the polymer (B) is associated with a metering pump and at least one spinneret each and at least one convergence thread guide and one eyelet each are arranged as a means for merging for at least two part threads as well as a winding means.
  • the means to unite the partial threads is an eyelet, a pin or a swab tail.
  • the device according to the invention preferably contains two to four spinnerets per spinning position. The device could have more than four spinnerets, which would further reduce the effort per spinning station.
  • the number of filaments emerging from each spinneret is not critical: it is preferably two, since this arrangement is the best known. However, it is quite possible to vary this number up to three or four.
  • the device contains a swirling nozzle between the merging point and the winding-on means, so that the threads obtained, the individual components of which are treated separately with spinning preparation on the convergence thread guide, receive a thread closure.
  • each spinning position has a separate cooling treatment.
  • the clamping length of each cooling treatment can be varied separately in order to achieve certain thread properties.
  • the length of the blow duct for this treatment is e.g. B. between 1 and 2 m.
  • the invention relates to the use of synthetic threads consisting of two part threads spun from the same or different polymers. These threads can be used as such or stretched and heat treated, but are preferably textured or stretch textured, false twist stretch textured.
  • the polymer melts of the separate polymers A and B pass from the extruder (not shown) into the corresponding metering pumps 3 and 4.
  • the spinning position of polymer A is denoted by 1 and that of polymer B is denoted by 2.
  • the metering pumps 3 and 4 convey the respective polymers through lines 5 and 6 into the spinnerets 7 and 8.
  • Each of these spinnerets has holes for two part threads. These partial threads 9 and 10 solidify below the nozzle due to the cooling effect of the blown air C.
  • the clamping lengths of the partial threads 9 and 10, d. H. the distance between the nozzles 7 and 8 and the convergence thread guides 11 and 12 were chosen to be the same in the case of FIG. 1.
  • the spin preparation treatment of the partial threads takes place at the convergence thread guides 11 and 12.
  • a partial thread 9 and 10 each made of polymer A and B are then combined into a thread at the joining points 13 and 14 and wound onto two winding devices 16 and 17 after the eyelet 15 has passed through.
  • Each winding device 16 and 17 driven by motors 21 and 22 has four full thread windings 20 on the corresponding mandrel 18 and 19.
  • Curve (D) shows a basic polyester partial thread and curve (E) a regular polyester partial thread of different titer, respectively.
  • Normal basic and regular polyester partial threads were produced on the device according to FIG. 1 with a take-off speed of 3100 m / min.
  • the thread titer is dtex 150 f 36, the basic component titer (A) dtex 80 f 16 and the regular component titer (B) dtex 70 f 20.
  • the clamping length for the components (A) resp. (B) is 140 and 120 cm.
  • the combined partial threads are interlaced with a knot density of 7.4 knots / m.
  • the thread thus produced results in a spun-like thread after the stretch texturing, which is used in weaving, knitting and warp knitting.
