Definitions

  • a iinish may, by way of example, be a lubricant, an anti-static agent, or a plasticizer. of course, be understood that ⁇ thechosen finish or tinishes must be applied to all the filaments and, as nearly as possible, uniformly to the entire tow.
  • the banding jet as employed prior to the present invention basically comprises a structure delining a passageway for the strand of filaments, the passageway beingl bounded on at least one side by a slotted or otherwise apertured plate through which compressed air from any suitable source is permitted to enter the said passageway for the purpose of blowing the filaments apart into the form of a more or less fiat band. T he slots are orientedperpendicularly to the direction of movement of the tow.
  • KnownV finish applicators generally comprise such devices as transfer rollers, paddle wheels or spraying heads.
  • the lilaments have ⁇ a tendency to come together again subsequent to their leaving the banding jet and especially in the applicator region, whereby the application of the finish is rendered substantially nonuniform, in some instances to such an extent that contiguous groups of lilaments located within the inner regions of the tow receive no inish at all.
  • Another object of the present invention is the provision of a novel type of banding jet for use in opening and applying iinish to continuous iilament tows.
  • a further Vobject of the present invention is the provision of such a jet in which the tow-spreading chamber and the finish-application chamber are constituted by one and the same filament passageway.
  • a related object of the present invention is

  • FIG. 9 is a top plan view of 'a d-ii Schlt modification of an orifice plate which may be employed as a part of the bran-ding jet of the applicator.
  • the apparatus employed is composed of an improved and novel banding jet in combination with a duct Ior conduit system through which the required compressed 4air is fed to the jet, while the finish to be applied to the yfilaments is added to -t-he air stream.
  • the means by which the finish is lintroduced into the air stream may be located laterally of or in longitudinal alignment with the air duct, the s-ole requirement being that the fin-ish is entrained by the stream of air and carried thereby into the banding jet.
  • the jet itself preferably comp-rises a plenum chamber coextensive in width with the lament passageway, whereby the air is distributed over an expanse equal to the said passageway prior to be-ing admitted into the latter.
  • Communicationbetween the plenum chamber and the pas- 8 is a sid-e elevational view of the top plate of the lsageway over the entire expanse ⁇ of the forme-r is estab lished by an 4oriiice plate which is provided with a plurality of elongated slots which in the plane of the plate form an angle of about 30 to 60 and preferably about 45 withV the direction of movement of the filaments.
  • the air admitted into the passageway exits through the tow outlet and also through the inlet. As it leaves through the inlet it causes the filaments to spread apart. Consequently the filaments are already in open condition when they reach the slots in the jet at which location the air has its maximum concentration of treating agent entrained as a mist or fog due to its having been sprayed into lthe moving air stream.
  • the openness of the tow opposite the slots ensures a uniform deposit-ion of treating agent and, as noted, the expanding air moving counter-current to the tow predisposes it to effective treatment.
  • both groups 4of slots oriented angularly, i.e. obl-iquely, to the direction of filament movement, and with the slots in one group being oriented substantially transversely to the slots in the other group to define a herringbone pattern.
  • the minimum width of the slots ranges from about 0.004 to 0.010 inch.
  • the process according to the present invention is particularly well suited for use in the application of finishes to synthetic filaments dry or wet spun through a multiorifice spinnerette the ⁇ construction of which is well known and per se constitutes no part of the invention herein.
  • the filamentary materials may comprise organic derivatives of cellulose such as the esters or ethers thereof, eg. cellulose organic acid esters such as cellulose acetate, cellulose propionate, cellulose butyrate, cellulose benzoate, cellulose acetate formate, celluose acetate propionate, cellulose acetate butyrate, and the like, ethers such as ethyl cellulose, etc.
  • the esters may be ripened and acetone-soluble, such as conventional cellulose acetate, or may be substantially fully esteried, i.e., contain fewer than 0.29 free hydroxyl groups per anhydroglucose unit, such as cellulose triacetate.
  • the filaments may, of course, be made of other materials of thermoplastic nature.
  • these materials are the superpolyarnides such as nylon, superpolyesters such as polyethylene terephthalate, polyglycolic acid and copolymers thereof, polymers and copolymers of vinylidene compounds such as ethylene, propylene, vinyl chloride, vinylidene chloride, vinylidene cyanide, acrylonitrile, vinyl acetate, and the like.
  • the finishes may comprise a variety of substances designed, as hereinbefore indicated by way of example, for lubricating, static charge-inhibiting and/or plasticizing actions.
  • Lubricants which lend themselves to the process of the present invention are, for example, light mineral oil, olive oil, polyalkylene glycol ethe-rs of alcohols containing about 8 to 18 carbon atoms, polyalkylene glycol esters of acids containing about 8 to 18 carbon atoms, and other materials well known in this art.
  • Anti-static finishes which may be employed are, ⁇ for example, salts of amines such as triethanolamine or dibutylethanolamine with an acidic material such as oleic acid, stearic acid, higher alkyl partial esters of phosphoric acid, e.g. decyl, lauryl or stearyl mono-phosphate, alkyl or aryl sulfonic acids or partial sulfates, sodium salts of these Iacidic substances, magnesium chloride, quaternary ammonium salts, and like materials.
