Definitions

  • ABSTRACT A process and apparatus for producing a composite yarn in which an inner continuous core yarn is covered with a layer of tightly wrapped staple fiber, the core is fed into a false twisting device located between the source of the core and its take-up point and staple fibers are conveyed by means of an applied electrostatic field to the surface of the core as it is twisted on the up-stream side of the twisting device.
  • An additional object of this invention is to provide an improved process for fiber deposition on a traveling core fiber by conveying the fibers to the point of assembly on the traveling yarn by means of a cooperating electrostatic field.
  • a further object of this invention is to provide an improved apparatus for effecting the process of the invention.
  • FIG. 1 is a schematic side elevation of a system effective for carrying out the process of this invention.
  • FIG. 2 is a schematic front elevation illustrating part of the apparatus of FIG. 1 and showing the manner in which the core travels with respect to the electrostatic lines of equipotential.
  • FIG. 1 of the drawings in which numeral 10 represents a source of supply of core yarn, the yarn being indicated by the numeral 11.
  • Core yarn I1 is fed from source 10 through a plurality of other mechanical feeding and twisting devices, to be explained, to an ultimate point of collection 12, where it is wound once again into an integral package.
  • Yarn 11 is withdrawn from source 10 by means of two pairs of feed rolls 13, two
  • pairs of rolls being shown only by way of example and not by way of limitation, and around a diverter plate 14 which alters the direction of travel of yarn 11 toward a twisting device 15.
  • a set of take-up rolls 16 On the other, or downstream, side of twisting device 15 is a set of take-up rolls 16 which feeds the material to the previously mentioned storage or collection point 12.
  • the storage package is driven frictionally by wheel 17 that is shown as being rotated by motor 18 through belt 19.
  • the twisting device 15 is at a site located between the source of supply 10 and the point of collection 12 so that twists of opposite directions are created in the yarn, as indicated schematically by numerals 20 and 21. Twister 15 may be driven by any suitable means, such as for example, an integral motor or by means of a friction belt drive not shown. In the present instance for the sake of simplicity, we have shown the twisting device 15 as including an electric motor and being appropriately connected to a source of electricity 22.
  • the device 15 will also include, among other things, a yarn gripper (not shown) which permits movement of the yarn parallel to the axis of the twisting device. It is apparent that more than one twisting device can be used in series fashion, if desired, to produce yarns having selected, predetermined special characteristics.
  • an electrode which cooperates with an opposed electrode at a suitable distance away from the twisting device to create the electrostatic field.
  • the electrode is indicated generally by the numeral 25 and is shown as being mounted in approximately the same region as where gripping of the textile fiber outer cover would occur. It is obvious that the electrode need not be located actually within the twisting device but could be located nearby. It is preferable, however, that the electrode be located as closely as possible to the actual twisting device so that concentration of electrostatic force lines will occur to thereby optimize the attraction of the staple fibers to the surface of the core yarn 11.
  • the other electrode is in this case shown as being the fiber feed rolls 30 from which staple fibers 31 are ejected into the field created by electrodes 25 and 30.
  • Fibers are fed into the feed rolls 30 from a conventional drafting apparatus indicated generally by 32.
  • the material being fed can be in the form of sliver, roving, or the like.
  • the electrical system indicated at 33 again is shown only by way of illustration, since alternative systems could be used to develop the electrostatic field.
  • fibers could be fed into the electrostatic field by some means other than the mechanical means shown, such as an air stream, or by other mechanical means.
  • the important aspect of delivering the fibers into the field is not the apparatus by which they are introduced, but rather that they be introduced in separated fashion, so that there are discontinuities in the flow of incoming fibers to enable rotation of the core material independent of the incoming fibers. This characteristic of the system is called open endness and it overcomes the occurrence of fiber bridging between the core and the fiber input unit.
  • the lines of equipotential of the electrostatic field are caused to assume the distribution indicated generally by numeral 40 in FIG. 2 of the drawings. It is an established fact that fibers travel normal to the lines of equipotential thus reaching the yarn tail 11 as illustrated in FIG. 2 of the drawings. Such fiber approach to the tail provides the focusing of fibers on to the tail thus enabling the optimization of fiber trajectories.
  • the fibers 31 are exiting from the feed rolls 30, only one of which is shown, and are drawn inwardly toward the yarn for assembly on its outer surface.
  • the yarn with the fibers twisted thereabout in one direction enters into the twisting element 15 and passes through the gripper contained within the twisting device.
  • the gripper is not shown in detail in this application but for one gripper and twisting system which is suitable for application in the present process, reference is made to U.S. Pat. No. 3,552,] l2, which issued Jan. 5, 1971 to Chabot.
  • the process of this invention is first of all continuously feeding core yarn from a source of supply to a point of collection, in this case the source of supply is located upon cone 10 and the point of collection by take-up package 12.
  • the yarn is twisted in a fashion that causes it to have opposite twists on each side of the twisting mechanism.
  • a portion of the length of core yarn located between the source and site of twisting is subjected to an electrostatic field that is created by the opposed electrodes, the electrodes conveniently being located at the fiber source and at the twisting site.
  • staple fibers are fed into the electrostatic field which then convey the fibers into contact with the core where the twisting of the core causes them to become tightly wrapped about it.
  • a process for producing a composite yarn having an inner continuous core yarn and an outer layer of staple fibers wrapped tightly and uniformly along the length of the core comprising:
  • false twisting means disposed between said source of core yarn and said collecting means for twisting the core yarn
  • separate electrode means generating an electrostatic field and positioned with respect to the length of core yarn extending from said source to said twisting means that the electrostatic lines of equipotential are substantially normal to the direction of travel of core yarn;
  • a source of staple fibers positioned for delivering fibers into said electrostatic field.
  • An apparatus for producing composite yarn comprising:
  • tential are substantially normal to the direction of travel or core yarn, one electrode of said electrode means being mounted in operative association with said twisting means and the other electrode of said electrode means being non-rotatable about the axis of the core;
  • a source of staple fibers positioned for delivering fibers into said electrostatic field.
