15 Claims. (Cl. 117-2) winding from the spinning room bobbins to spools This invention relates to improvements in the methods of setting the twist of rayon yarn,
- whereby it becomes possible to spin the yarn directly onto weaving or shuttle bobbins, without the necessity of rewinding it to other carriers as a result bf the yarn becoming soft or loose on 'the bobbins, due to'a twist-setting operationg,
thereby eliminating time, expensive machinery and a high labor cost. Yarns having the twist set by my methods will not have to be kept in a conditioning atmosphere. It also applies to the setting of the twist of rayon yarn spun onto intermediate bobbins, or carriers, from which it must later be rewound onto weaving or shuttle bobbins, v or to other carriers; such rewinding not being necessary because of faulty twist-setting, but simply to get the yarn onto a more convenient carrier. It also applies to the setting oi the twist of cotton, wool, real silk, cellulose acetate, and other natural or artificial fibres spun directly onto weaving or shuttle bobbins, or onto intermediate bobbins for a later rewind onto suitable carriers; 7
it also applies to the preparation of the yarn with the materials used previous to spinnig and then spinning directly onto weaving or shuttle bobbins, or onto intermediate bobbins, the yarn, after spinning requiring no after-treatment to set the twist, when properly prepared, before spinning.
Yam properly treated by my process will be firmly and tightly wound on the bobbin, or other carrier to which it has beentwlsted and will not require a rewind becauseit is not firm or tight. Moreover, said yarn will not soften, or become loose during the storage. Any rewindingrequired will be for the purpose of transferring the yarn to a more convenient form of carrier and not because v i of the yarn becoming loose, as the result of the twist-setting? Another feature of myimprovement is that the twist-setting materials can be recovered and re-used.
the present time, consists in preparing it for spinning by employing a preliminary treatment, as sizing, waxing, oiling, or other treatment, then passing it through the spinning process and winding it onto bobbins, "not weaving or shuttle bobbins, The yarn on the bobbin is now too lively,
due to tendency to kink, to be'handled and the twist must beset before the yarn can be further starches, dextrines, oils, waxes, by steaming, or by a combination of materials. The treated yarn is The usual method in spinning rayon yarn, at,

processed. This is accomplished in several ways; by means of water or water solutions of gums,
on spooling machines, and then winding from spools to the weaving or shuttle bobbins on expensive winding machines. The cost of twist-setting and rewinding is high and my process is designed to eliminate much' of the expense.
When rayon yarn is spun directly from a spinning frame onto weaving or shuttle bobbins and the twist set by the methods in use at the present time, such as immersing the yarn in water, or in water solutions of gums, oils, waxes, starches, dextrines, etc., or steamed, the yarn, especially in storage; may swell and soften so that in some cases the bobbin can be pulled away from the I yarn. Such-bobbins cannot be used for weaving. Claims aremade that the yarn doesnot swell, but
that the bobbin dries out. I' claim, for myimproved process, that it will remedy the trouble,
gwhatever the cause. If due tothe bobbin drying,
my treatment will overcome the dimculty for, if a properly conditioned bobbin is used at the start, it becomes coated with a protecting layer of wax, oil, or rosin, or other binder, and would neither dry out nor swell appreciably. Moreover, my
treatment need 'not appreciably alter the natural moisture content of any yarn to which it may be applied, and therefore,,the tendency to swell in storage, due to water take-up, would be minimized. If'the fabric to be treated is'a crepe consisting of a highly twisted filling for instance 50-55 turns per inch per denier 40 filament rayon), and the warp ordinary untwlsted rayon,
and the warp is sized with a mixture similar to that used in setting the twist, the use of expensive humidifying apparatus in weave rooms can be eliminated, and the bobbins and yarn will not be exposed to changes in atmospheric conditions to produce swelling or drying out. My
ment, therefore, consists-in employinfa binder for the yarn which does not cause it to swell, or
soften, and does not permit bobbin to dry out with humidity Y T J The main object of my processis onto weaving or shuttle'bobbins, protection is also clairned'for twist-setting f the some solutions, if intermediate bobbins; are us'e'dr-the yarn being rewolmd onto the shuttle bobbins, un-
