6 Claims.

This invention relates to plied textile yarns and fabrics made therefrom.

In accordance with the present invention the plied yarn is of such character that the yarn of one of the plies projects from the yarn of another ply along the length of the latter whereby fabric woven from such yarn has certain desirable characteristics or properties. More particularly such fabric has a full lofty hand, appears thick in comparison with its weight, and has a somewhat metallic appearance.

The plied yarn of the present invention is produced by plying direct spun synthetic yarn, which is shrinkable by wetting, with yarn which is less shrinkable by wetting than said direct spun yarn. The less shrinkable yarn may be of either natural or synthetic origin and may be continuous filament yarn or spun yarn which is less shrinkable than direct spun rayon or nylon yarn. As a result of the differential wet-shrinkability of the yarns of which the plied yarn is produced, in accordance with the present invention, wetting of the plied yarn, either as yarn, before being incorporated in the fabric, or after it is incorporated in the fabric, results in the direct spun yarn of the plied yarn shrinking considerably more than the other yarn of the ply, whereby the latter projects or fiuffs up laterally of the plied yarn. As a result, the fabric formed from said yarn has the characteristics referred to above.

The invention will now be described in greater detail with reference to the accompanying drawings which however are to be considered as illustrative of the invention but not in limitation thereof. 7

In the drawings:

Fig. 1 is a plan view, on an enlarged scale, of a piece of fabric embodying the present invention;

Fig. 2 is a view, on a greatly enlarged scale, of a length of plied yarn of the present invention, before said yarn is treated for shrinking the same;

Fig. 3 is a View similar to Fig. 2 showing the plied yarn after it is subjected to the shrinking operation.

As shown in Fig. 2, the plied yarn I comprises direct spun synthetic yarn I2 and yarn it which is less shrinkable than said direct spun yarn I2. The direct spun yarn I2 may be produced from filamentary rayon, including nylon, according to any suitable direct spinning process, for example as described in the application of Charles E. Neisler, Jr., Serial No. 640,727, filed January 12, 1946, and now abandoned. As described in said application, direct spun yarn is produced from continuous rayon filaments by tensioning and rupturing said filaments to produce staplefibers which are spun into yarn. As a result of the tensioning of the filaments, the staple fibers of the spun yarn are in attenuated condition and will shrink considerably when wetted without requiring stretching of the spun yarn. It will be understood that the wetting of the direct spun yarn may be accomplished either by the dyeing operation or by a separate operation, the former being preferred. As stated above the less shrinkable yarn I4 may be either natural or synthetic yarn and if desired may be either continuous filamentary yarn or spun yarn. Said less shrinkable yarn I4 may also be constituted of direct spun yarn which has been shrunk before it is plied with the companion non-shrunk yarn I2. As shown in Fig. 2 the less shrinkable yarn is twisted around the direct spun yarn I2, the latter being the core of the plied yarn thus formed.

The plied yarn I0 may now be used to produce the fabric which when wetted, for example in the dyeing operation, will cause the direct spun yarn I2 to shrink. thereby causing the less shrinkable yarn I4 of the plied yarn to project or fluff laterally of the companion direct spun yarn I2 along the length of the plied yarn, as illustrated more or less diagrammatically in Fig. 3 which is to be considered in comparison with Fig. 2. The flulfed yarn thus produced by the shrinking operation is indicated at IDA in Fig. 3 and is also indicated by the same reference character in the fabric F shown more or less schematically in Fig. 1.

In the fabric F the plied yarn I 0A is shown as the warp threads of the fabric, the weft threads being indicated at I6, but this maybe reversed. Preferably the threads I 6 are much thinner than the threads formed of the plied yarn IGA. and the Weave of the fabric is preferably such that the.

face of the fabric is constituted mainly by the threads formed of the plied yarn IOA, while the back of the fabric is constituted mainly by the thinner threads I6. It will be understood that this result may be readily accomplished by floating the threads I 6 over a considerable number of the plied yarn threads IDA at the back of the fabric. It will be understood however that I do not limit myself to any particular weave of fabric, and further it will be understood that the fabric may be formed so that only sections thereof are composed of threads formed of the plied yarn IIIA. In this connection it will be understood that various pattern effects may be produced according to the sections of the fabric which are formed of threads of the plied yarn in contrast with sections of fabric which are formed of yarn of different character. Fabrics produced in accordance with the present invention may be made of yarn of Various sizes according to the intended uses of the fabrics. More particularly, the fabrics may be used for furniture, dresses and other garments, etc.

As illustrated in Figs." 2 and 3' the yarn M is preferably thicker, i. e., of a larger size than the direct spun yarn [2 of the plied yarn. It will be understood however that the' two plies" of the plied yarn may be of the same thicknessvonisize or may otherwise vary in thisrespect relatively to each other depending uponthe desired' effectQ 'iIt is also preferred that the lessshr'i'nk'abl'e yarn M of the plied yarn I 0 have less twist than the more shrinkable yarn [2. In accordance =with the pres- Y ently preferred mode of practicing the..present invention, the direction-of twist of yarn I2 is opposite that of yarn l4, and in the plying operation the plying twist is in such'direction as to increase the twist of the directspun yarn l2 and to dec-reasethetwist of the yarn l4.

It-will'be understood that while I have'illustr'ated and descri-bedthe presently preferred form of'my invention, "the latter is susceptible to'variousbhanges and modes of" practicing the- "same. Accordingly itwill-be understood that various changesmay be "made without departing from the underlying ideaorprinciples of this invention. within'the scope-of the appended claims.
