• washing ofthe cake without destroying its ability to be reeled off is elfected by rotating it rapply of water-tothe cake, and owing moreover to lthe' instant removal of the water in an outward direction, the thread never has a chance to float, and the positions of the threads are not altered by the finely divided I particles of liquid sprayed upon them,'nor 1s the shape 0 the threads altered, as by a coarse spray used heretofore.
• the cake therefore does not lose its coherence or shape, I because during this careful washing its coherence is maintained by the action of the centrifugal force.
• the washingprocess can be carried to completion ver expeditiously.
• the centrifug-' ing is preferably continued for some time afterthe supply of water has been shut off.
• Water subdividers or sprinklers of the. pe which spray the water onto the cakeof t tliread practically in the form of mist are especially suited for this purpose.
• Such exceedingly fine subdivision of the water ensures a high degree of protection for the spun cake. Fine subdivision and uniform application of the water 'all over the spun cake are essential, but it is of secondary 1mportance whether this application of finely divided water to the cake e effected by means of pressure, suction, or centrifugal action.
• the washing process which may be concomitant to the spinning operation, may, if necessary, be carried out onthe spinning machines, that is to say, on the actual spinning spindles themselves, and it has been ascertained that my washing process always lasts a the action of chenncal agents, such as acids,
• the washing machines are fitted with the required number of washing sp reception of the. vessels containing the spun cakes and with the driving mechanism reuired therefor, with pipes for the washing uid, nozzles for sprinkling the cake, protective and collecting devices for catching the fluids thrown off, corresponding exhaust and discharge pipes, and, if necessary, any suitable appliances for drawing off gases and vapors evolved.
• the first wash waters which contain the ma'or portion of the reagents of the spinning ath adhering to the threads, may be carried off separately, so as to permit the ready recovery of the chemicals, if desired.
• De-sulphurizing, bleaching or softening reagents may be added to the wash water, or to a portion thereof.
• a process for the treatment of artificial silk which comprises spinning a cake of thread having a plurality of concentric lay-' ers in a spinningreceptacle, supplying an atomized washing liquid with the cake while in its spinning receptacle and su ported by the outer walls of such receptac e, the inner indles for the walls of the cake supported, and rotating the remaining mechanically unthe receptacle and eliminating com ined by further rotating the rece tacle with the cake, then reeling the threa and finally drying it in hanks.
