Definitions

  • the invention relates to a method for co-spinning synthetic threads consisting of two partial threads spun from the same or different polymers on a double spinning position from two spinning positions arranged next to one another.
  • the invention further relates to a device for carrying out this method and the use of synthetic threads produced in this way.
  • US Pat. No. 4,025,595 relates to a process for the production of mixed filaments with 20 to 68 fibrils and a titre of between 70 and 260 denier, in which at least two fiber bundles are co-spun, tangled separately, drawn together and then at an entanglement level between 45 and 80%. According to this process, fully drawn threads are produced in a double spinning position.
  • the two 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 object of the invention is to provide a method that allows higher productivity with less financial outlay per spinning station.
  • the invention relates to a method for co-spinning synthetic threads, consisting of two partial threads spun from the same or different polymers on a double spinning position from two adjacent spinning positions, characterized in that one polymer is spun into at least two partial threads in each spinning position , the partial threads of the different partial thread groups are subjected to a separate treatment before two partial threads of the different partial thread groups are combined to form one thread at the joining point and then wound up, and that the partial threads from a spinning position are preferably wound onto at least two winding devices .
  • slow-spun or preferably fast-spun yarns are produced without stretching before winding.
  • the fast-spun thread is partially drawn and must be draw-textured if it is used for texturing.
  • 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 flat or drawn yarn.
  • spinneret with a semicircular arrangement for the capillaries. Preferably one places per spinning position four to eight strands. In this case, two to four spinnerets are used, which are arranged side by side, ie the four, six or eight spinnerets on the same line, or the spinnerets of one spinning position on a line offset from the spinnerets of the other spinning position.
  • threads are produced with a final titre of between 50 and 600 dtex, preferably between 50 and 260 dtex. Also the titer is the. Single filaments uncritical.
  • the threads obtained are LOY (Low-Oriented-Yarn) or POY (Partially-Oriented-Yarn), preferably POY, produced at a winding speed of between 2500 and 6000 m/min.
  • the partial threads are preferably wound onto two winding devices.
  • polyesters are polyesters 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.
  • ethylene glycol can still other diols such as 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol or cyclohexane-dimethanol, and in addition to terephthalic acid, respectively.
  • dimethyl terephthalate or other dicarboxylic acids such as isophthalic acid, adipic acid, azelaic acid, dimer fatty acid, respectively. the alkyl esters of these acids are also used.
  • Polyester-polyester polyamide-polyamide, polypropylene-polypropylene as well as polyamide-polyester, polyamide-polypropylene, polyester-polypropylene combinations in
  • feed threads for spun-like threads can also be produced.
  • modified, i.e. regularly and basic-dyeable, polyesters are combined.
  • the 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, base-dyeable polyester it additionally contains a polyalkylene glycol or a polyolefin, as described in 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 covering component and that of the other spinning position forms the core component.
  • the titer-related stretching force ratio of the partial threads made from different polymers is greater than 2 with a reference stretching between 1:1.2 and 1:2.
  • the clamping length in the blowing shaft can be varied separately.
  • the blast air temperature, the blast air pressure and the blast air humidity are known to be set and can also be varied separately, as can the type and amount of spin finish applied.
  • the invention further relates to a device for co-spinning synthetic threads, consisting of two partial threads spun from the same or different polymers on a double spinning position from two adjacent spinning positions, with a cooling treatment and a convergence thread guide for each partial thread , a means for combining two partial threads from different partial thread groups and a winding means, characterized in that each spinning position has at least one spinneret for at least two partial threads, and that the winding means preferably consists of at least two winding devices.
  • the means of uniting the partial threads is an eyelet, a pin or a pig 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 exiting each spinneret is not critical: it is preferably two, since this arrangement is the most common. However, it is entirely possible to vary this number to three or four.
  • the device contains an intermingling nozzle between the point of union and the winding means, so that the threads obtained, whose individual components are treated separately with spin finish on the convergence thread guide, receive a thread cohesion.
  • each spinning position has a separate cooling treatment.
  • the clamping length of each cooling treatment can be varied separately in order to achieve specific thread properties.
  • the length of the blowing duct for this treatment is, for example, between 1 and 2 m.
  • the invention relates to the use of synthetic threads consisting of two partial threads spun from the same or different polymers.
  • These filaments can be used as such or drawn and heat treated, but are preferably textured or draw-textured, namely false-twist draw-textured.
  • 1 a device according to the invention with an arrangement of four spinnerets per spinning position
  • 2 the stretching force curves of two partial threads produced according to the invention.
  • the polymer melts of the separate polymers A and B reach the corresponding metering pumps (3) and (4) from the extruder (not shown).
  • the spinning position of polymer A is denoted by (1) and that of polymer B by (2).
  • the metering pumps (3) and (4) convey the corresponding polymers through lines (5) and (6) into the spinnerets (7) and (8). Each of these spinnerets has holes for two strands. These partial threads (9) and (10) solidify below the nozzle due to the cooling effect of the blown air (C).
  • the spin finish treatment of the strands takes place at the convergence point (11) and (12).
  • Partial threads (9) and (10) each made of polymer A and B are then combined to form a thread at the meeting point (13) and (14) and, after passing through the eyelet (15), are wound onto two winding devices (16) and (17). .
  • Each take-up device (16) and (17) driven by motors (21) and (22) has four full thread turns (20) on the corresponding mandrel (18) and (19).
  • Normal basic and regular polyester filaments were produced on the device according to FIG. 1 at a take-off speed of 3100 m/min.
  • the as-spun titer of the thread is dtex 150 f 36, the basic component titer (A) being dtex 80 f 16 and the regular component titre (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 produced in this way results in a spun-like thread that is used in weaving, knitting and warp-knitting.
