Definitions

  • My present invention relates to improvements in axially expandable stand for the liquid aftertreatment of yarn packages, in particular rayon cakes, for liquid after-treatment prior to drying.
  • the freshly spun artificial silk wound in packages may be after-treated in various ways according to the kind of sp nn p s e p oye
  • Such after-treatment may consist of washing, desulfurizing or, generally, removing impurities introduced during the spinning process, shading off and bleaching, whereupon the material is bleached.
  • the material Prior to bleaching, the material may undergo dyeing and sizing operations.
  • the operations of bleaching, dyeing and sizing for example, ma enter into consideration.
  • the so-called irrigating method is used most frequently.
  • Great packag weights and modern artificial silk possessing extremely fine fibrillae or filaments require, however, a very long time of treatment. Further, the handling of such large packages in transport is rendered difiicult. According to another frequently applied method of treatment,
  • the treating liquid is forced through the package under pressure.
  • My present invention aims to overcome the said disadvantages in the treatment of tubeless yarn packages, in particular of artificial silk.
  • the package is mounted on a perforated elastic shell of a stand or holder on which it is exposed to the action of a liquid or liquids moved under pressure from the inside to the outside of said shell and then through the yarn package.
  • a treating stand which also forms part of my invention, has proved of special value.
  • Such stand comprises a liquid supply line communicating with the interior of a resilient shell which is perforated and serves for receiving the yarn package to be treated.
  • the said shell interconnects two hold-down elements disposed on its end faces, one of said elements being displaceably guided to permit change of its distance from the other element.
  • Fig. 1 is a vertical median sectional view of the stand through the shell and Fig. 2 is a sectional view of a portion of Fig. 1,
  • the resilient shell I is made of rubber for example, and is perforated at 2. Only the apertures 2 lying in the plane of the drawing are shown, in reality a great number of narrow apertures 2 are provided, which are disposed uniformly distributed over the entire surface of the shell I. The dimensions of the latter are adapted to the inside dimensions of the package or cake A to be treated.
  • the shell I is secured at its end faces to a lower circular bed plate 4 and to an upper circular plate 5 by means of inwardly bent flanges 3 and an auxiliary ring 6- and bolts I.
  • a central spindle 8 traverses the lower plate 4 by means of its shouldered and threaded foot portion 9. The said plate 4 is secured to the spindle 8 by means of a nut ID.
  • the said spindle portion 9 further, traverses an aperture provided in the bottom of an open tank II, and a nut l2 screwed onto the spindle portion 9 secures the tank II to the spindle 8.
  • the spindle portion 9 forms a pipe connection and is provided with transverse bores l3 within the range of the inside space of the shell I. tion of the spindle portion 9 serves for connection to a pipe (not shown) through which the treating liquid is supplied.
  • a stud I4 is mounted axially displaceably in an upper longitudinal bore The lower end porgaged on the threaded upper end. portion 20 of the stud M.
  • the said cover I8 is provided with a central aperture for receiving the stud endportion 20, and forms a hood disposed at some distance from the upper end of the shell 1.
  • the cover 18 comprises an outwardly projecting flange 2
  • the lower plate 4 is provided with cross bores 23. In place of the said bores, suitably adapted grooves or channels also could be pro vided.
  • the package A which is formed of freshly spun artificial silk, is cross-wound and protected by cloths (not shown) wrapped about the same.
  • the package A is put over the shell I so as to be freely supported on the lower plate 4.
  • the cover l8 which has been detached from the stud 14 prior to mounting the cake A onto the shell I, has again been secured to the stud M, the cake is ready to receive its treatment, an annular space being left between the inner face of the package A and the shell I.
  • the appropriate treating liquid is admitted under pressure through the lower spindle portion 9 into the space defined by the shell I and the plates 4 and 5.
  • the shell space is filled by the liquid supplied through the apertures l3, and the shell I is radially expanded so as to fit snugly the inside face of the cake A.
  • the liquid then flows through the apertures 2 into the cake A, the said apertures having been widened on account of the expansion of the shell 1. Due to the fact that the yarn turns of the cake A do not yield radially, the cake will only yield in the axial direction of the shell I, as shown by the arrow in Fig. 2.
  • the angle of crossing a of the yarn windings is changed correspondingly, and the cake A, thus, is slacked or loosened, that is, rendered more permeable to the liquid. After the latter has passed through the cake, it is caught in the tank H from which it is run, according to the manner of treatment for the cake A, to waste or into a collecting vat forrecycling.
  • the method described eliminates the. necessity of providing a sealing closure of the yarn package A on its end faces.
  • the edges of the package therefore, are stressed only to a nominal extent, that is, are gently treated.
  • the amount of treating liquid passing through the package A is, for a given cross-wound package, a function of the pressure, the number and size (diameter) Of the holes 2 in the shell I, and of the elongation of the package.
  • the amount of liquid may easily be varied in the limits 1:20.
  • the duration of treatment is decreased with an increasing rate of flow of liquid through the package. For example, cakes of artificial silk containing mineral acid, which ordinarily have to be irrigated for 60 hours, can be freed from the acid in ten minutes when treating the same in accord with my present.
  • the holding plates 4, 5 consist of corrosionresistant material.
  • Apparatus for use in the Wet after-treatment of a package of rayon filament yarn comprising an elongated perforated, open ended, resilientshell, around Which the package of yarn is to be placed for treatment, said shell having at each end an inwardly extending flange, a lower bed plate secured to the lower flange of said shell and an upper plate secured to the upper flange of said shell, a central spindle having an axial bore at its upper end and being threaded at its lower end portion, penetrating into said lower bed plate, and fixed thereto by a nut engaging said threaded portion, a stud slidable in said bore, a collar on the upper part of the stud above said upper flange, said stud being threaded above said collar, a cover mounted on said stud and having a.
