Paul Saifert, Wolfen Kreis Bitterfeld, Germany, assignors to I. G. Farbenindustrie Aktiengesellschaft, Frankfort-on-the-Main, Germany Application February 11, 1937, Serial No. 125,230 In Germany February 13, 1936 1 Claim.
Our invention relates to the treatment of bundles of artificial fibers.
One of its objects is an improved process of treating bundles of artificial fibers. Further ob- 5 'jects will be seen from the detailed specification following hereafter.
This invention relates to an improvement 1''. or modification of that described in the application Ser. No. 55,308 filed December 20, 1935 (British Patent No. 451,944) of which one of us is a coinventon The essential feature of the process described in that application is the continuous treatment of a wet bundle of fibers of considerable thickness under conditions free from tension. For the success of the process it is necessary that formation of knots and entanglements in the bath, even when-,there is a considerable accumulation of the fibers therein, should be avoided in order that the bundle of threads may travel smoothly through the several baths. The greater the amount of bundle in any individual bath the more difficult it generally is to ensure undisturbed'travel of the bundle, while on the other hand a large store of bundle in the baths facilitates a longer period of treatment and saves space.
The present invention is based on the observation that the entanglement of the bundle in the baths may be effectively prevented and the quantity of bundle in the baths may be increased if care is taken that the descending bundle does not float even temporarily on the surface of the bath but passes without delay vertically or nearly vertically through the surface. This cannot always be attained without assistance in the case of dry or squeezed bundles of fibers by permitting a free descent of the bundle, since the continuous passage through the surface is frequently interrupted by air bubbles adhering to the bundle. In the process of the invention the satisfactory introduction of the bundle of fibers into the liquid of the bath is secured by so wetting and thereby simultaneously charging with liquid the bundle of fibers which is descending into the bath,-that the bundle passes through the surface of the bath without check and deposits itself in the vessel continuously and uniformly. For this purpose the bundle is preferably supplied with such quantity of a suitable liquid that it is practically soaked and may practically be contained in a column of liquid in passing into the treating liquor of the bath.
The descending bundle may be thoroughly wetted by conducting it through a funnel-shaped 5 vessel, the bottom opening of which is preferably of such diameter, that the bundle and the liquid continuously running to the funnel can pass through the opening without disturbance. It is advantageous to place this funnel device at such a height above the surface of the bath that 5 the weight of the wetted bundle in combination with that of the column of the liquid surround-. ing the bundle assists the passage of the latter through the funnel. In order to facilitate the threading of the bundle the funnel may consist 10 of two parts so that it can be opened for the introduction of the bundle and then closed for the operation.
The bundle falling into the bath collects as it comes to rest in the form of a loose layer on the 15 bottom of the vessel from which without necessity of a guide in the bath it can be withdrawn smoothly laterally or upwardly and without formation of knots. The liquid necessary for wetting and weighting the fibrous bundle may be 20 pumped from the bath into the funnel. An especially simple mode of operating consists in allowing the. ascending bundle itself to lift to the required height of the liquid necessary for wetting and weighting the bundle that is to enter 25 the bath. In this case the ascending bundle loaded with the liquid of the bath is passed between two squeezing rollers or stripping devices and the expressed liquid is collected by a trough and directed into the funnel through 30 which the descending bundle is passing. The liquid raised by the ascending bundle sufiices, when the arrangement of the collecting trough is suitable, to wet and charge the descending bundle with so much liquid that it can penetrate 35 the surface of the bath without check. The distance between the surface of the bath and the squeezing or stripping device should not be too small (for instance it may be above 1 m.). The bundle is then suspended and passes between 40 the squeezing rollers with its individual fibers parallel to each other. This orientation of the fibers is produced by the downward tension of the liquid which the ascending bundle carries.
In order to secure a uniform deposition of the 5 bundle accumulating in the bath, the wall of the vessel containing the bath may be inclined or there may be used an endless conveyor band as indicated in the aforesaid application Ser. No. 55,308 whereby the distribution of the bundle is 50 ensured.
The accompanying drawing is a diagrammatic representation of an apparatus suitable for applying. the process of the invention.
The thick bundle of fibers a, which is issuing from a spinning machine or a sliver can or any other container, is led over a roller 1) or over several rollers at uniform rate and passes into the vat c; the weight of the bundle assisted bythe liquid column by which it is surrounded falls vertically into the bath and is received on the curved plane (2, down which it slides to the bottom of the vat. In the latter the bundle accumulates in dependence upon the duration of the treatment in the bath. The fibrous bundle is withdrawn from the bath by means of a roller I or by several such rollers and at e is squeezed by two rollers, the expressed liquid being received in the trough g from which it flows into the funnel 71. through which the descending bundle passes. The funnel preferably consists of two parts hinged together at i and fastened at It so that it can be opened and closed. In the drawing the funnel is shown to be stationary, however,
it is also within the scope of our invention to impart a movement to it so that it may follow the bundle if the latter is moved to and fro over the length of the roller b according to the process described in the application Ser. No. 55,308.
Instead of the foregoing device which has been thoroughly tested there may be used an arrangement by which the liquid of the bath is pumped on' to the descending bundle of fibers.
The following example serves to illustrate our present invention:
An endless bundle of cellulose hydrate fibers having a weight of 10 to 15 grams per meter is falling into a bath through a funnel having an opening of 15 mm. diameter at its narrowest part, said funnel being arranged 2.5 meters above said bath. The bundle is withdrawn from the bath and is brought to the starting height by means of squeezing rollers with a speed of 12meters per minute. Thefliquid squeezed off by said rollers, which amounts to about 300 to 500 cc. per minute, is added to the bundle in the funnel. If necessary the amount of said liquid may be increased by liquid which is pumped into the funnel.
What we claim is:
A process of continuously washing. after-treating and dyeing bundles of artificial threads in suitable treating liquids under conditions free from tension which comprises guiding the bundle on a substantial distance through the air so that it falls vertically on the treating liquid, loading the bundle with treating liquid while it is falling through the air, allowing a considerable piece of bundle to accumulate in the treating bath and withdrawing the bundle from the treating liquid, removing from the bundle the treating liquid carried with it and using said part of the treating liquid to load the bundle while it is falling through the air before entering the treating liquid.
