Definitions

  • a further object of the invention is to provide a method and apparatus of the kind mentioned above which does not cause damages to fibers at the time of treatment and which consumes a less amount of electric power.
  • a substantially nontwisted continuous multifilament material in the form of yarn, strand, tow or the like is passed through a narrow passage of a first electrode so as to be in contact with the inner side of the first electrode and then through a second electrode having a potential difference of at least 500 volts from the first electrode, said second electrode being spaced from the first electrode and spaced also from the passageway of the continuous multifilament material in such a manner that the individual filaments divided or spread out of the multifilament material would not contact the second electrode.
  • the multifilament material is electrically charged.
  • the individual monofilaments constituting the multifilament material are pulled or displaced outwardly toward the inner wall of the second electrode so that the multifilament material is divided or spread into individual monofilaments, which may be taken-up separately or treated in a manner known in the art (refer, for example, to US. Pat. No. 3,358,436).
  • the invention may be applied to any kind (inorganic or organic, hydrophilic or hydrophobic) of textile material provided that it is in the form of a solid continuous substantially non-twisted material consisting of a plurality of monofilaments, typical example of such material being multifilament yarn or tow which is well known in the art.
  • FIG. 1 is a schematic front view of an apparatus embodying this invention
  • FIG. 2 is an enlarged longitudinal section of the electrodes shown in FIG. 1;
  • FIG. 4 is a view similar to FIG. 2 but showing still another form of electrodes.
  • FIG. 1 indicated with the numeral 1 is a package of a continuous multifilament yarn 2.
  • a continuous multifilament yarn 2 is produced by melt, wet or dry spinning a fiber-forming material into monofilaments, which are'stretched for molecular orientation and then wound up to form the package 1.
  • a textile processing agent such as anti-static agent, lubricating agent, emulsifying agent, etc. which has been applied to the filaments during the spinning operation.
  • the yarn 2 of the package 1, without having any further preparatory treatment applied thereto, is withdrawn by feed rolls 3 through tension means 4 and passed through a first electrode 5 and then through a second electrode 6.
  • the monofilaments spread in this way may be used for various applications which are known in the art, such as for the production of non-woven fabrics, various blended yarns, etc. (refer, for example, to US. Pat. No. 3,358,436).
