(o1. .2S-i6) 21 Claims.

This invention relates to textile fabrics, and more particularly to a Woven fabric having puckered and non-puckered portions.

I t is the primary aim and object o f the present invention to provide a fabric of this type of which a portion or portions are puckered by certain yarns in the fabric which are shrunk relative to the other, non-shrinkable or less shrinkable yarns in the fabric, on merely subjecting the fabric to any finishing process in which the same becomes wet, without requiring stretching or any other special treatment of the woven fabric or of the yarns from which the fabric is woven.

It is another important object of the present invention to provide a fabric of this type in which the shrunk yarns are made of rayon, and the other yarns may be o f any suitable kind that will not shrink, or shrink less than, the shrunk rayon yarns.

It is another object of the present invention to provide a fabric of this type which, without any pre-treatment of the yarns thereof, will after its one-time shrinkage shrink no more when washed or otherwise wetted.

It is another important object of the present invention to provide a fabric of this type, the one-time shrinkage of which is definite, predeterminable and permanent.

The above and other objects, features and advantages of the present invention will be more fully understood from the following description considered in connection with the accompanying illustrative drawings.

To accomplish the aforesaid objects, I have made use of the discovery that directspun rayon yarn will, on becoming wetted once in non-stretched condition, permanentlyshrink a definite predeterminable amount, and thereafter shrink no more regardless of how oftn it may be re-Wetted. 1n forming this rayon yarn by the spinning process, the continuousflilaf ments from which Athe fibre staple is produced are ruptured by a tensioning process which involves the passage of a bundle of continuous rayon filaments between successive pairs of rolls of which the rolls of the front pair are driven at greater peripheral surface speed than the rolls of the rear pair so that the laments are tensioned and ruptured into staple fibre due to the tension on the filaments in passing from the rear rolls to the front rolls. Thel fibres thus spun by the direct spinning process, involving tne rupture of the contlnuous rayon fila-ments, are in attenuated condition in the yarnformed therefrom. In accordance with the present invention, direct-spun rayon yarns of thisV type are used for the threads to be shrunk in the fabric. The other yarns or threads in the fabric may be of any desired kind so long as they are non-shrinkable, or less' shrinkable than the direct-spun rayon yarns.

Referring now to Fig. 1 of the patent drawings, there is shown, by way of erai'nple,- a piecel of fabric 3` in which smooth flat stripe-like' portions 32 alternate with p uckere'di stripe-like portions 34. In the present instance, the' warp threads se within the connes of the smo-oth fabric portions 32 are direct-spun rayon yarns, while the femmine warpthreads as' within" oie connes of the puckered fabric portions 311V may be` any suitable yarns that are non-shrinkable, or shrink less than the direct-spun rayon yarns 3 6. The weft threads 40 may be of any suitable, preferably non-shrinkable kind, and may, if lde si1 "e d, be the sameas the warp threads 38. The

warp threads

36, 38 and weft` threads 3 40 are conventionally interwoven into the fabric 30.

The fabric thus woven comes off the loom in at, non-puckered condition, since none of the

threads

36, 38 and 4D have been tensioned in the manufacture of the fabric beyond the normal slight tension imparted to them while being interwoven in the loom. When the fabric becomes thereafter wettedin the course of any conventional finishing process, such as dyeing or bleaching, the direct-spun warp threads 36 will shrink relative to the other warp threads 38 in the fabric, resulting in a definite permanent warp-wise contraction of the fabric portions 32 in which the direct-spun threads 36 extend. Warp-wise contraction of the fabric portions 32 will result in puckering of the fabric portions 34 (Fig. 1) within the confines of which extend solely the substantially nonshrinkable threads 33 and 48. After being once wetted and permanently shrunk in consequence thereof, the fabric will shrink no more when subsequently washed or otherwise wetted. Thus, the originally smooth, flat fabric will, on becom ing initially wetted, change its face pattern to that shown in Fig. l, and will permanently hold this pattern regardless of how often the fabric is re-wetted.

As already mentioned, the final and permanent face pattern of the fabric may conveniently be imparted to it on its subjection to any conventional nishing process, in the course of Which the fabric becomes wet, as in dyeing or bleaching, for instance. It is to be noted also that the threads in the fabric are not pre-treated in any way prior to their use in the loom, nor are they stretched while being interwoven in the loom. Further, the fabric coming from the loom requires, for the formation of its final and permanent face pattern, neither stretching nor tensioning nor any other treatment, other than mere wetting.

By way of example, a highly satisfactory fabric of the type shown in Fig. 1 has been obtained, by using for the shrinkable warp threads 36 direct-spun yarn 66 single cotton count made from one and one-half denier viscose rayon tow, and by using for the other warp threads 36 yarn of 900 denier 46 filament viscose rayon. While in the fabric just described the shrinkable direct-spun threads are arranged in the warp, they may obviously be arranged in the weft only, or in both, the warp and weft.

Fig. 4 shows a piece of fabric 50 in which the present invention is embodied in a manner to produce a crepe effect. Thus, in the manufacture of the fabric 56, the shrinkable direct-spun rayon threads 36 alternate, in the present instance in the warp, with non-shrinkable or less shrinkable yarns 38 of any suitable kind. The weft threads 46 may, as in the case of vthe fabric shown in Fig. l, be of any suitable,

preferably non-shrinkable kind. The fabric 56 comes off the loom in a smooth flat condition, and is thereafter subject to any conventional nishing process, such as dyeing or bleaching, in the course of which it becomes Wet. When the fabric is thus wetted for the first time, the direct-spun threads 36 will contract (Figs. 4 and 6), resulting in longitudinal crinkling of the non-shrinkable or less shrinkable warp threads 38 (Figs. 4 and 5). It is the predominant appearance on either face of the fabric 50 of the crinkled threads 38 which lends to the fabric its crepe effect.

Reference is now had to Fig. 7 in which the present invention is embodied in a band 54, having smooth selvage edges 56 flanking a puckered, intermediate stripe-like portion 58. In the present instance, the shrinkable direct-spun yarns 33 are arranged in the band 54 warpwise Within the confines of the selvage edges 56, while the remaining warp threads 38" may be of any suitable non-shrinkable or less shrinkable kind. The weft threads in the band 54 may likewise be of any suitable, preferably nonshrink-able kind. The band 54 is, prior to its initial wetting, entirely flat, and its permanent face pattern, i. e., the smooth selvage edges 56 and the puckered intermediate portion 58, will emerge on the initial wetting of the band, as will not be understood. Fig. 8, like Fig. '7, shows the contract between the smooth selvage edges 56 and the puckered intermediate portion 58 of the band.

The present invention may also be applied for the formation of a ruffled band 60 (Figs. 9 and 10) having a smooth selvage edge 62. In this instance, the shrinkable direct-spun threads 36a are arranged in the band 66 warp-wise within the confines of the selvage edge 62. The remaining warp threads 38a may be of any suitable, substantially non-shrinkable kind. As in the case of the band 54, the instant band 60 is, prior to its initial wetting, fiat throughout its surface area, and its permanent face pattern, i. e., the smooth selvage edge 62 and the ruled remainder of the band, emerges on initially wetting the band.

Figs. 1l and l2 show a modified band 66 of which opposite ruffled margins 68 are joined by an intermediate smooth stripe-like portion 10. To this end, the shrinkable direct-spun threads 36h are arranged in the band 66 warp-wise within the confines of the intermediate band portion 16. The remaining warp threads 38D may be of any suitable, substantially non-shrinkable kind. The weft threads may also be of any suitable, preferably non-shrinkable kind. As in the case of the

bands

54 and 60, the band 66 is, prior to its initial wetting, flat throughout its surface area, and its nal and permanent face pattern emerges on initially wetting the band, as will now be readily understood.

Reference is now had to Figs. 13 to 18, showing a piece of textile fabric in which the present invention is embodied in a manner to produce a facey pattern on the fabric which is different from those of the previously described fabrics. The instant fabric has a face pattern which is characterized by a multitude of raised formations of any desired design on the adjacent face of the fabric. Thus Fig. 13 shows the fabric as having on its front face regularly arranged, raised rib-like formations 82. The instant fabric 80 is formed of conventionally interwoven warp and

weft threads

84 and 86, respectively. The warp and

weft threads

84 and 86 may be of any suitable, preferably substantially non-shrinkable kind. For convenience, the warp and

weft threads

84 and 86 may be said to form the woven body 88 of the fabric.

Also interwoven with the

body threads

84 and 86 are intermediate portions of additional, laterally spaced threads 90 which are direct-spun rayon yarns that are known for their definite and permanent shrinkage on being wetted for the first time. In the present instance, the additional threads 9D are indicated as warp threads. These additional threads 90 are so interwoven with the body threads 84 and 8G that they have intermittent floating portions S2 on the back of the fabric. In weaving the fabric 8f4, the additional threads 95 are tensioned no more and no less than the other threads 84 and 85, so that the iloating portions 92 of the shrinkable threads 98 do not sag, but lie normally against the woven body 88 of the fabric in the manner shown in Fig. 16.

The floating portions 92 of the shrinkable threads 99 in the fabric are arranged in orderly groups 94 for the purpose of forming on the front face of the fabric the regularly arranged raised rib-like formations 82, respectively, on wetting the fabric for the first time. As in the previous examples, the instant fabric Sil may be wetted in the course of any conventional finishing process, such as dyeing or bleaching, for instance. When the fabric 8E! is thus wetted, the additional threads 90 thereof will shrink. The body 88 of the fabric will not bulge where the shrunk threads 9G are interwoven with the

body threads

84 and 86. However, the floating portions 92 of the shrunk threads Si?, being unconnected with those portions of the body 88 of the fabric which they bridge in the manner shown in Figs. 14 and 16, will cause these body portions to rise above the front face mi) of the fabric in the manner shown in Fig. 1'7. The effect of the shrinkage of the threads 90 upon the fabric is also apparent from a comparison between Figs. 14 and 15, Fig. 14 showing the fabric before shrinkage and Fig, l showing the same after shrinkage. The numerous groups 94 of oating thread portions 92 on the back of the fabric will, on wetting the fabri-c for the rst time, raise the fabric portions adjacent the iioating thread groups S4 into the raised rib-like formations 82 on the front face IBG of the fabric (Fig. 13) Hence, the coordination of the floating thread portions 92 in each group, and the distribution of the iioating thread groups 94 on the back of the fabric, will determine the raised pattern on the front face of the fabric. n

While in the fabric just described, the additional shrinkable threads 9i! are incorporated in the fabric as warp threads, they may instead be incorporated in the fabric as weft threads (Fig. 20) having fioating portions |02` on the back of the fabric which are arranged in groups E04 to form on the face of the woven fabric, on wetting the latter, raised formations of the general shape indicated at H36, for instance.

The shrinkable threads 90 may further be interwoven with the.

body threads

84 and 86, both as warp and weft threads in the manner illustrated in Fig. 2l, in which the floating portions HD of the shrinkable threads 90 intersect each other to form, on wetting the woven fabric, a raised substantially quadrilateral formation H2 on the front face of the fabric.
