bus in accordance with the invention.
' A known process of making threads from visbose consists in producing from the viscose xanthate threads; soluble in water or alkali, and then to convert the xanthate thread to a cellulose thread in a second bath. The conversion of the water-soluble thread by means of a mineral acid is performed either on the running threador on the wound-up thread. For obtaining staple fibers it has been proposed that the xanthate thread spun from the viscose should be cut on the winding device and the mass of threads converted into cellulose fibers by introduction into an acid bath.
*IIn the process of the present invention the iranthate threads spun in known manner into ammonium-sulphate solution, organic acid. solution or dilute mineral acid solution are collected from a large number of spinning nozzles to form a thick bundle of several thousand deniers which is then conducted to a cutting machine. The thick bundles are cut into staple and the, staple threads are floated in dilute mineral acid whereby a good mechanical loosening-of the bundles into separate threads is produced together with a good crimping and at the same time a conversion of the xanthateinto cellulose. As the liquid for, the floating and the conversion there may advantageously be used sulphuric acid of 1-10 per cent. strength. The acid may be mixed with sodium sulphate or any other of the additions known to be useful in spinning baths for making artificial silk. It is particularly advantageous to use a conversion bath containing, inpresence or absence ofan acid, an oxidizing agent, suchas activin, hypochlorous acid or hydrogen peroxide. The mass of fibers, obtained by the mechanical loosening in the conversion bath and by the con- .version and crimping of the xanthate thread cut of the textile machines. In the process of the invention there is no-sticking together of sepa-- rate threads "which could not be avoided in the older processes, wherein the xanthate threads were wound on spools or reels before they. were cut. v
- A particular mode of thlnvent'ion is describedwith reference to the accompanying. diagram showing incross section a suitable apparatus for the purpose.
Viscose is spun to xanthate threads in an ammonium sulfate solution of 25 to 30 per cent. strength, containing 5 per cent of sodium sulfate, and the bundles of fibers are united from numerous spinning nozzles to form a. thick band a. After passing through a draw-off device b having the form of rollers driven in opposite directions, the band, without strong-pressure, is guided continuously ,to a cutting machine 0, whereby it is cut to the desired length of staple. In the cutting operation provision must be made for the shrinkig. effect on the fiber of the later conversion into cellulose. The cut fibers fall into a trough d into which the conversion liquor flows, namely sulfuric acid of '8 per cent. strength containing 12 per cent. ,of sodium sulfate. In order to separate the cut staple length into separate threads the conversion bath is constructed with one or more towers e, e1, having batlles j for scatterin the fibers. At the lower end of such tower the mass of fibers isreceived on an endless conveyor sieve g and thereby separated from the liquid. This conveyor transports thefieece a'gain upwards in a slanting direction and delivers it into a further tower e2, also having baiiie plates 1; here the fibers are washed free from conversion liquor by water. The threads are passed in similar man-- ner through all the necessary treatment baths. At the end of each conveyor sieve the fibrous mass is passed between pressure rollers h in order to express the absorbed liquid. Finally the fibers pass on to the conveyor bands of a drying cupboard 1. Instead of the after-treatment of the fibers in scattering towers in the manner described, there may be used for the afterrtr'eatment a powerful sprinkling with the various liquids on the conveyor sieves. Or such a sprinkling may be supplemental to the treatment in scattering towers.
The treating liquors are collected in troughs it under the conveyor sieves whence they are discharged to tanks 1 where they are adjusted to the original concentration and returned to. the towers by means of pumps m.
The product of the invention is a staple fiber in the form of a fleece of good wool-like crimping, which is very suitable. for spinning.
