METHOD or SPINNING THREADS.
Application filed December 12, 1925. Serial No. 75,142..
This invention relates to "methods of spinning threads and-more particularlyto methodsl of twisting artificial s1lk.
Heretofore, it has been customary to take i a `5 th strands from a spinnarette, roll them on a reel, and then mount the reel on a vertically disposed spindle for twistlng the strands into the final thread.
.This method is open to several objections. lo The highspeed necessary in twistlng the Lthread causes breakage of the thread and the ballooning caused by centrifugal force at the speed employed throws an obJectlon- -able mist from the still wet strandslof silk l5 which is disagreeable. l
Another method of twisting threads of artificial silk is by means of a centrifuge basket but this'v method is also open to several objections. l
The method of twisting threads formlng the subject matter of the present invention consists of a combination of the' two methods referred to by means of which the disadvantages of each method are eliminated and the advantages retained. In practicing the process .forming the subject matter of the present invention, the strands as they come from the spinnarette are rolled on a reel in the usual manner and this reel is then mounted on avertical spindle. In-y stead of rotating the, reel at a sufliciently high rate ofspeed to give'the finall twistl tothe thread, thereel is rotated at'a slower speed, ordinarily from 10 to -50 per cent. of the usual speed, for the purpose of partially twisting the thread. The thread is then run into 'a centrifuge basket rotating at sufficient speed to give the additional twist needed. lThe advantages of.n the centrifugevtwisting are retained in that the final washing'solution may be run 1through the basket in the usual manner and the silk then run off into skeins.
In the accompanying drawings, we have diagrammatically illustrated apparatus particularly useful in practicing the process. In this showing: V
Figure 1 is a diagrammatic side elevation of the formed strands passing from'a' spinnarette to a reel,- and,
twistlng of the thread partially on the rcel and partially in a centrifuge basket, the centrifuge being shown in vertical section.
Referring to the drawings, the reference Fi ure 2 is a similar viewshowing thev numeral 1 designates a spinnarette of the` usual type by means of which a suit-able` cellulose solution is projected into a precipitating bath (not shown) .to form a plurality of strands 2. These strands are carried upwardly and collected on va reel 3 which is mounted to revolve on a shaft 4. The reel may be arranged over a pan 5 containing asuitable washing solution. After the strands .have been collected or' rolled on the reel, it is removed from the shaft 4 and mounted on a vertical spindle 6 for twisting.'A The spindle is revolved .by
4 any suitable means=(not shown) but vinstead of revolving the spindle at a very high ratel of speed, which would tend to throw the thread 7 a considerable distance outwardly, as-it passes to the guide 8, the spindle isl revolved at a rela-tively slow rate of speed soithat the ballooning of the thread is ma-` ter'ially reduced, as indicated at, 9. As stated, the spindle may be" run atfroni 10 to 50 per cent. of its ordinary speed and preferably at about one-third the speed usually employed to impart the full twist to the'thread. The partially twisted thread is then passed upwardly over a reel 10 mounted on a suitable shaft 11 Aand t-henr downwardly through a guide 12 of a centrifuge. As shown, the guide 12 is provided with a funnel at its upper lend by means of which the nal washing solution may be passed lover the thread andit is furtherprovided with an arm 14 extending outwardlytherefrom by means `of which the guide may be reciprocated in the usual manner. The een? trifuge is ofI the ordinary/'construction and consists of an outer casing 15 having a drain or outlet 16. A shaft 17 extends through thev casing and carries a basket 18. This basket is provided with suitable openings .19 in its vertical wall which rmit the washing solution to pass to the outer casing "6 at a low rate of speed and is then dellvered f to the centrifuge operating at a sufficient same, and that various changes in the shape,
give the thread the additional twist 1. The method of twisting artificial silky which comprises placing a reel containing strands of such silk on a spindle, rotating the reel at a relatively low rate of speed to partially twist the withdrawn strands and :t'orm a thread, and then passing the partially twisted thread into a centrifuge to' complete the twisting. l
2. rlhe method of twisting artilicial silk which comprises placing a reel containing strands of such silk on a spindle, rotating the reel at from 10 per cent. to 45() per cent. of the speed necessary to fully twist said strands, withdrawing the strands from said waage@ rotating reel to partially twist them and @t form a. thread, and passing the partially` twisted thread through a centrifuge to complete the twisting operation 3. rThe method of twisting artiiicial silk a which comprises placing a reel containing @E strands of such silk on a spindle, rotating the reel at substantially one-third of the speed necessary to fully twist said strands"9 withdrawing the strands from 4the rotating ,reel to partially twist them and form a 3@ thread, and passing the partially .twisted thread into av centrifugetoV complete the' twisting operation.
In testimony whereof, we ailix our signatures. i
