Definitions

  • the present invention relates to a yarn and a method of manufacturing a yarn.
  • the present invention is therefore based on the object to a yarn create a flame-retardant effect, but with less Use of flame-retardant material can be produced.
  • This object is achieved by a yarn that as a core yarn is formed and a soul containing a cellulose fiber, and a coat, which contains an acrylic fiber.
  • the core of the core yarn essentially completely out of the Cellulose fiber is formed.
  • the soul contains a cotton fiber.
  • the core contains a combed yarn or a carded yarn from a cellulose fiber.
  • the jacket substantially completely formed from the acrylic fiber is.
  • the jacket is a flame-retardant acrylic fiber contains.
  • Z-wire is to be understood as meaning a thread which, in the Z-direction, that is counterclockwise, is rotated.
  • the jacket in the Z direction that is counterclockwise, turned on the soul.
  • the yarn has a twist coefficient ⁇ (metric) of at least about 80, preferably of at least about 100, in particular of at least about 105.
  • the core yarn has a rotation coefficient ⁇ (metric) of at most about 200, preferably at most about 140, in particular of at most about 120, has.
  • the material of the shell with a basic delay of at least about 20, preferably at least about 25, spun is further provided.
  • the "basic delay” designates the factor by which the material roving when spinning to the core yarn over its original one Length has been stretched.
  • the material of the shell with a default of at most about 50, preferably at most about 40, spun.
  • the material of the soul is preferably with a low Anspannverzug stretched; So it has proven to be favorable if the material the soul with a tension of at most about 1.05, preferably of at most about 1.04, more preferably at most about 1.03, spun.
  • Core yarns are obtained when the core yarn contains the acrylic fiber in a proportion of contains at least about 50 weight percent.
  • Claim 20 is directed to a textile, which is a core yarn according to the invention includes.
  • the present invention is based on the further object of a method to produce a yarn which has good flame resistance has and with the least possible need for flame retardant Material can be produced.
  • This object is achieved by a method for producing a Yarn solved in which a core thread containing a cellulose fiber, with a sheath roving containing an acrylic fiber is wound around so To form core yarn.
  • the core thread contains a cellulose fiber, the need for reduced flame retardant acrylic fiber material for the production of the yarn.
  • Claim 40 is directed to a textile, which is a according to the invention Process manufactured yarn includes.
  • FIGS. 1 and 2 designated as a whole with 100 ring spinning machine comprises a flyer bobbin 102 on which the material, which the jacket of a produced with the ring spinning machine 100 core yarn should form, is arranged as a jacket roving 103.
  • the jacket roving 103 drawn off from the flyer bobbin 102 passes over two Deflection pulleys 104 and 106 in a drafting system 108 of the ring spinning machine 100, which is a pair of input rollers 110, a pair of center rollers 112 and a pair of output rollers 114, wherein the sheath roving 103 each passes between the two rollers of a pair of rollers.
  • the material that is to form the core of the core yarn is as soul thread 116 on a cylindrical coil 118, for example a cardboard spool, arranged, with horizontal and substantially parallel to the rollers of the drafting system 108 aligned coil axis below the vertically oriented flyer coil 102 on a rod 119 in the creel of the ring spinning machine 100th is up.
  • the core thread 116 withdrawn from the cylindrical bobbin 118 wraps around once a delivery shaft 120 disposed below the cylindrical bobbin 118 and then via a guide roller or Pinterrolle 122 in the drafting system 108 of the ring spinning machine 100 introduced.
  • the pinter roll 122 is provided with a provided annular notch in which the core thread 116 runs to the core thread 116 in the axial direction of the pinter roll 122 exactly relative to to position the jacket roving 103.
  • the jacket roving 103 is stretched in the drafting system 108 in two stages, namely once between the input rollers 110 and the center rollers 112th and once again between the exit rollers 114 and the center rollers 112th
  • the thus stretched jacket roving 103 is by the rotation of the spindle 128th the ring spinning machine 100 at the output of the drafting device 108 twisted, so that there is the spin triangle 124 shown schematically in Fig. 3 forms of the lower end of the end yarn 126 down to the spindle 128 of the ring spinning machine 100 is running, which is at high speed (for example about 10,000 to about 11,000 revolutions per minute) and so on the end yarn 126 is wound on a sleeve 130 plugged onto the spindle 128.
  • the core thread 116 is the drafting unit 108 of the ring spinning machine 100th supplied by means of the Pinterrolle 122 so that the core thread 116 exactly centered enters the spinning triangle 124 (see Fig. 3) and so from the stretched Mantle roving 103 which is turned around the core thread 116, completely enclosed and encased.
  • the end yarn 126 thus formed is formed as a core yarn whose structure is shown schematically in Figs. 4 and 5.
  • the end yarn 126 has a core or a soul 132 formed from the core thread 116.
  • This core 132 is substantially completely surrounded by a jacket 134, which is formed from the jacket roving 103 and the core thread 116 to Outside of the end yarn 126 towards substantially completely covers.
  • a twisted core thread 116 is used and the jacket roving 103 in the same direction of rotation, which is the soul thread 116th has rotated around the core thread 116 around.
  • a core thread 116 becomes with a Z-rotation, ie a counterclockwise rotation, used.
  • Z-rotation ie a counterclockwise rotation
  • Such a Z-twisted thread, also called Z-wire is shown schematically in Fig. 6.
  • the sheath roving 103 is around this Z-wire as the core thread 116 also in the Z direction, that is counterclockwise, turned around.
  • a core thread 116 with an S-rotation that is with a clockwise rotation used becomes.
  • Such a thread with S-twist which is also called S-wire, is shown schematically in Fig. 7.
  • the jacket roving 103 also in the S direction, ie clockwise, turned around the core wire 116 formed as S-wire so as to a complete coverage of the core thread 116 through the jacket 134 to achieve.
  • the ring spinning machine shown by way of example has 100 two parallel to each other drafting devices 108, so that simultaneously produces two Endgarnfäden 126 with this ring spinning machine 100 become.
  • the end yarn 126 could also be with a ring spinning machine 100 are generated, which has only one drafting system 108.
  • jacket roving 103 an acrylic fiber yarn is used, which under the name "Protex M” from Waxman Fibers Ltd. in Grove Mills, Elland, West Yorkshire, HX5 9DZ, UK. This roving can be used in particular as a Flyerlunte with a fineness Nm 2.25 (number metric).
  • the core thread 116 is a combed, long staple cotton fiber yarn used. This yarn contains 100 percent cotton. The fineness of this Yarns can be chosen in particular to Nm 85.
  • the core thread 116 used is designed as a Z-wire, that is in the Z-direction turned.
  • the drafting system 108 of the ring spinning machine 100 is adjusted so that the Mantle roving 103 is stretched with a base draft of about 34. Further, the drafting device 108 is adjusted so that the core thread 116 with a Pinterverzug of about 1.03 enters the drafting system 108.
  • the spindle of the ring spinning machine 100 rotates at about 10,500 rpm per minute.
  • the direction of rotation of the jacket 134 is adjusted so that the jacket 134th rotates around the core thread 116 in the Z direction.
  • a final yarn 126 is then a core yarn with a soul 132 of the cotton yarn and a coat of the Protex acrylic yarn, wherein the Flame retardant acrylic fiber lies outside and the soul 132 from the cotton yarn essentially completely covered.
  • the fineness of the end yarn 126 is about Nm 40/1.
  • the weight fraction of the acrylic fiber at the end yarn 126 is about 53 Weight.
  • the weight content of the cotton fiber on the end yarn is about 47% by weight.
