17 Claims. (01. 139-391) This invention relates to' a novel fabric having tufts or tassels on its face, and to a method of manufacturing the same.

One of the objects of the invention is to provide a novel fabric of this type in which the tufts or tassels are formed from groups of parallel threads which, when the fabric is initially woven, are woven into the body of the fabric at spaced intervals and are floated over the surface of the fabric between the points where they are woven into the body of the fabric, said floating sections of the parallel groups being subsequently cut to form the tufts or tassels.

In the preferred manner of practising the invention, the fabric is initially woven with the end portions of the floating sections of the groups of parallel threads temporarily held in place orbound to the body of the fabric by binder threads, and after the floating sections of the parallel groups have been cut or severed these binder threads are removed, thereby freeing the end portions of the floating sections and forming the tufts or tassels.

These groups of parallel threads from which the tufts or tassels are formed may be either groups of filling threads or. groups of warp threads, but preferably such groups ofthreads are groups of filling threads, in which case the temporary binders which temporarily hold the end portions of the floating sections of the groups will be warp threads.

The binder threads may be removed from the fabric in any suitable way, such as by mechanical means, or by a chemical operation, or by carbonizing them out. If they are to-be removed by chemical treatment of the fabric or by carbonization, it will be understood that the materials or fibres used in the various threads of the fabric must be such that the chemical treatment or the carbonizing action will affect the binder threads only. Where the binder threads are to be mechanically removed from the fabric it is proposed to tie said binder threads into the fabric by anchoring threads which are interlocked with orcross the binder threads on each side of each group of tuft-forming threads, and then to segment these anchoring threads so that by applying a pulling force to-the binder threads they may beeasily withdrawn from the fabric.

If desired the tufts or tassels which result from the removal of the binder threads can be treated either mechanically or chemically or otherwise to enhance the decorative effect.

The basic weave or body of the fabric may be either a plain weave, twill, sateen or any combinations or variations of them as desired, and the threads of the fabric may be made of any suitable material, such as cotton, wool, mohair, alpaca, ramie, silk, rayon, linen or any other fibre or filament, natural or synthetic, or any combinations of such fibres or filaments which can be drawn, thrown or spun into a thread suitable for use in weaving'a fabric. The fabric may be so made that the free ends constituting the tufts or tassels may be of various lengths, that is, they may be relatively short, in which case they might more properly be termed tufts, or they might be relatively long, in which case they might be more properly described as tassels. For convenience, however, I will refer herein to such free ends as tufts, said term being used to include the groups of thread ends which project from the face of the fabric regardless of the length thereof. I

In the drawings wherein I have illustrated more or less diagrammatically a fabric embodying my invention and one way of weaving the same;

Figs. 1, 2, 3 and 4 are diagrammatic views illustrating various steps in the operation of weaving the improved fabric;

Fig. 5 is a view illustrating the completed fabric;

- Figs. 6 and 7 are diagrammatic views showing the floating anchoring threads on the back side of the fabric;

Fig. 8 is a sectional perspective view of the fabric as it is initially woven;

Figs. 9 and 10 are fragmentary sectional views showing one way in which the temporary binder threads may be removed from the fabric;

Fig. 11 is a diagrammatic view also illustrating one manner of removing the binder threads;

Fig. 12 is a diagrammatic section of a fabric made in accordance with the invention and as it comes from the loom;

Fig. 13 is a diagrammatic view illustrating a fabric made in accordance with the invention but having relatively long tufts or tassels.

The body of the'woven fabric, 'or fabric base, is indicated at I and this is formed by interweaving warp threads 2 and filling threads 3 in any usual way so as to produce a plain weave, a twill or sateen or any other desirable base fabric.

In initially weaving the fabric various groups of parallel threads from which the tufts are subsequently formed and which, for convenience, will be referred to as tuft-forming groups, preferably are alternately woven into the body of the fabric land floated on the front'face thereof of tuft-forming threads are indicated at '4 and each group of threads is woven into the body of the fabric at spaced intervals, as indicated at 5 between the points 6 and 'l, and are floated over the surface of the fabric ,between the spaced intervals 5, as shown at 8. The length of the spaced intervals 5 in which the tuft-forming threads 4 are woven into the fabric may vary, and the length of the floating section 8 of each group of threads may vary in accordance with the design desired for the completed fabric, and

similarly the distance between the groups of parallel tuft-forming threads 4 may vary according to the design desired to be produced.

As stated above I will preferably weave the fabric so that the groups 4 of tuft-forming threads are groups of filling threads.

When the fabric is initially woven one or both end portions 9 of each floating section 8 of any group of tuft-forming threads is temporarily retained in position or tied to the body I of the fabric by one or more binder threads l0, and in the drawings I have shown each end portion 8 of each floating section 8 thus bound to the fabric body by two binder threads l0. However, the

number of binder threads in which are used for temporarily holding any end portion 9 in position may be varied without departing from the invention. These binder threads ill will preferably be widely spaced from the end or ends of the floating section as shown in the drawings.

Where the tuft-forming groups are fillingthreads, these binder threads III will be in the nature of binder warp threads, and one way of practising the invention is to weave the fabric initially so that each binder warp thread III is bound or interlaced with an anchoring or binding pick H at each side of each floating section, each binder warp thread floating over the floating tuft-forming groups as shown at I! and also floating over the face of the fabric between the tuft-forming groups as shown at l3.

Fig. 6 is a diagrammatic view of the back face of the fabric showing the binder picks ll, there being two such binder picks for each tuft-forming group of filling threads 4 and each binder pick floating on the back face of the fabric except where it is interlocked with the binder warp threads ID, as indicated at l4.

The fabric. illustrated is thus initially woven with a plurality of separate groups of filling threads, each of which groups is alternately Woven into the body of the fabric and floated over the surface thereof, and with the end portion or portions of each floating section retained in position by means of binder warp threads which are interlaced with binder picks or anchoring threads on each side of each tuft-forming group, and which binder warp threads float over the tuft-forming groups and then float over the face of the fabric between the points where they are anchored to the binder picks. A fabric w 'en in this way is shown diagrammatically in Fig. 1 and more in detail in Figs. 8 and 12.

After the fabric has been thus woven, the floating sections 8 of the groups 4 of tuft-forming threads are severed between the binding threads 18 and the binding threads are subsequently removed from the fabric to free the tuft-forming portions 8 of the floating sections 8. This severing of the floating sections 8 may be done merely by cutting the threads of each section between the binder threads I therefor, as shown in Fig. 13, or it may be done by removing an intermediate portion of each floating section between the binder threads I0 therefor, that is, by cutting away or removing the portions of each floating section between two points, such as the points a and b in Fig. 1, which would bring the fabric into the condition shown in Fig. 3. Where the floating sections 8 are simply cut as shown in Fig. 13, the end portions 9 will be longer than where an intermediate portion of each floating section is removed or cut away between the points a and b as shown in Fig. 3.

In order to facilitate this operation of cutting or severing the floating sections, I propose to treat the fabric I after it has been initially woven, as shown in Figs. 1 and 8, with the floating sections of tuft-forming threads and the binder picks. so as to set the fabric and raise the floating sections 8 somewhat from the face thereof as shown in Fig. 2. This may be done in any of the ways well known to the textile art by which the fabric may be shrunk somewhat in the direction of the length of the groups 4, thereby introducing some slack into the floating sections 8 which makes them lie loosely on the surface of the fabric between the binder threads and causes them to be separated therefrom as illustrated in Fig. 8. If desired the fabric may also be treated at this point in the operation in order to improve its appearance, and/or to remove dirt, grease or other impurities therefrom, but in any event after the fabric has been brought to the condition shown in Fig. 2 in which the floating sections 8 are slack, then said sections are severed, either as shown in Fig. 13 or byremoving the intermediate portions thereof as shown in Fig. 3. This may be done by means of any apparatus suitable for the purpose. The fabric will then be in the condition shown in Figs. 3 or 13 wherein it has on its front face the tuft-forming portions 9 of the floating sections 8 which are held to the face of the fabric by the binder warp threads l0, and these tuft-forming sections 9 may be longer or shorter depending on location of the binder-warp threads ID on the floating sections 8 and the manner in which the floating sections are sev-' ered.

After the floating sections 8 have thus been severed to produce the tuft-forming sections 8 the binder warp threads H) are then removed so as to free the tuft-forming end portions 9, which then become tufts l projecting from the face of the fabric, as seen in Fig. 4.

The removal of the binder threads Iii may be accomplished either mechanically or chemically or by carbonizing them out, or in any other desirable way. If the binder threads are to be removed or dissolved by a chemical action, it will, of course, be necessary to .0 weave the fabric that the material constituting the binder threads II and anchoring threads II will be responsive to the desired chemical action, while the other threads of the fabric *will be unaffected thereby, or if the binder threads are to be carbonized out of the fabric it will also be necessary to use such materialsfor the various threads of the fabric that the binder threads and anchoring threads will be the only ones which will be affected by the carbonizing operation.

I have, however, illustrated the binder threads as being removed from the fabric mechanically by being pulled therefrom, and where the invention is practised in this way it is necessary first to sever the binder picks or .anchoring threads H. The operations to which the cloth is subjected after it is initially woven, and by which the tuft-forming sections 8 are rendered slack and loose, as shown in Fig. 2, also results in introducing slackness or looseness into the binder picks i i between the points where they are interlaced with the binder warpthreads asillustrated in dotted lines Figx2. This makes it possible to treatthe back of the fabric so as to segment the binder picks ii, thusleaving only the portions it thereof which are interlocked with the binder warp threads, as shown in Fig. 7. After the binder picks or anchoring threads ii have thusbeen cut or segmented the binder warp threads it can be readily pulled out of the fabric by applying a pulling force thereto, as shown in Figs. 9 and 10. Fig. 9 is a'fragmentary view showing a portion of a binder warp thread it which is floating over the tuft-forming group of filling threads i, as shown at I12, and which is looped through the fabric body and interlocked with a portion it of the anchoring thread on the back side-of the fabric. By applying a pulling force to each binder warp thread, the loop is thereof will be pulled through the fabric, in doing which it will either pull the short section it of the anchoring thread through the fabric or will be pulled loose from said Short section.

Any suitable way of withdrawing these binder warp threads may be emp1oyed, and merely for illustrative purposes there is shown diagrammatically in-Fig. 11 pulling devices it adapted to apply the requisite pulling force to said binder threads. I

The removal of the binder threads and anchoring threads leaves the fabric in the condition illustrated in Fig; lwherein tufts it will be projecting fromone face of the fabric. The arrangement of these tufts may be varied almost indefinitely by varying the spacing of the groups of tuft-forming threads lengthwise of the fabric, and by varying the spacing of the places along the. length of each group at which each group is woven into the fabric, and by varying'the length of the space 5 between successive floating sections 8 in each group and by varying the manner in which the sections are severed.

While the fabric may be used in the condition shown in Fig. l, yet if it is desired to enhance the attractiveness thereof for certain purposes the tufts I5 may be curledor twisted either mechanically or in any suitable way as shown in Fig. 5, or the tufts may be chemically or otherformly over thesurface of the fabric or tuftshaving a random spacing or having a uniform spacing in one direction or a random spacing in the other direction etc., and may also be woven with tufts of various lengths.

Other changes may also be made in the practise of the invention within the terms of the claims.
