FABRIC Original Filed Dec. 30, 1941 Patented Mar. 6, 1945 FABRIC Benjamin S. Faber, New York, N. I.

Original application December Divided and 1944, Serial No. 529,709

7 Claims.

This invention relates to a new and improved frieze pile fabric and has for an object to provide such a fabric in which the loops are woven in a warp-wise direction of warp pile yarn which is passed to and fro in a weft-wise direction over -a warp-wise extending gauge or the like, while in the finished fabric, the loops lie and are held in a substantially warp-wis direction.

The invention consists in providing a fabric wherein the pile loops are formed without the use of any weftwise extending threads, wires or the like for supporting the loops as they are formed.

Another object of the invention consistsin providing a fabric wherein the threads are so arranged as to cause the loops to resist distortion or dislodgment with resultant lack of uniformity,

of the surfaca by reason of contact with objects exerting a pulling effect on one or more of the loops, or other vicissitudesof wear.

Another object consists in providing such a fabric wherein the loops may be formed of different heights on different parts of the fabric for the production of desired effects.

Another object consists in providing a fabric having a ground warp interwoven so as to extend longitudinally between the points at which alternate loops of each warp-wise row interweave or bind with the wefts, hereinafter referred to as the binding points of the loops, thus tending to prevent distortion or dislod'gment of the loops by pulling strains thereon.

This application is a division of my application for Method of making fabric, Serial No. 424,863, filed December 30, 1941, now Patent No. 2,355,- 789, the method claims in which application were allowed on February 5, 1944. This application is for the product made in accordance with the method claims allowed in the parent application.

In weaving frieze pile fabrics, it has been customary to use gauges disposed warp-wise or longitudinally in the loom, which gauges support permanent or removable weft-wise threads, over which threads the warp pile yarn is passed to form loops of a height predetermined by the height of the gauges, the pile yarn, of course,

being also interwoven with the ground of the.

fabric. In an alternative procedure. pile wires are inserted weft-wise and warp pile loops are formed thereover, the wires being drawn out after the formation of such loo In the fabric made according to my invention, the use of the said supporting weft threads or wires is entirely obviated, and the warp pile yarn is woven in such a relationship to the gauges this application 3., 1941, Sub] No.

and the ground of the fabric that the resulting pile loops, though woven to and fro over gauges with a motion that includes weft-wise as well as warp-wise travel, are definitely positioned and held in the finished material in a warp-wise direction. Furthermore the loops are so arranged with respect to certain of the ground threads that strongly resist distortion or dislodgment such, for instance, as the running which is a characteristic defect of frieze materials under certain conditions of wear.

The fabric and two weaves thereof are represented in the accompanying drawing, in which 1 represents a back plan view of a loose pile weave showing the fabric with the additional ground warp thread woven points of the row of pile loops,

Fig. 2 represents a sideview of the fabric as illustrated in Fig. 1, and

Fig. 3 represents a detail back plan view of a portion of my new and improved fabric in a fast Pile weave.

A fabric made in accordance with my invention comprises weft threads 5, pile war-p threads 6 and an additional ground warp thread 1.

warp threads i and the weft threads 5 closely and firmly together so that distortion of the fabric or displacement of the threads is prevented. The regular ground warp threads 8 serve to space the pile and provide a firmly woven back in the usual manner. It will be noted that the pile warp 6 first binds on one Side of the additional ground warp l and under weft thread 5 and then on the other side of I. This alternation continues each time the pile i binds into the back of the fabric.

The relationship of the threads is well shown in the back plan view of Fig. 1 and it will be clear that, as a result of this warp-wise passage of the ground warp I, and all its in the fabric, centrally between points of the warp-wise rows of pile loops, a, frictional binding effect is exerted on the loops where they interweave with the fabric ground Motion of the said extr fabric is as just described, it also assists in the warp-wise positioning of the pile loops and, of course, adds strength to the fabric ground & a whole.

It should be stated that this invention is adaptable to many different loop pile weave constructions, and that the number and arrangement of between the binding warp and weft th ead illustrated and described is chiefly for the purpose of illustrating a practical and desired embodiment of my invention in a suitable weave construction. It has been chosen to show one form of loose pile loop weave as shown in Figs. 1 and 2, because, as previously indicated, an important feature of the invention resides in the fact that the arrangement and interlacing of the threads, particularly in the form of the invention shown in Figs. 1 and 2 of the drawing, tends to prevent the distortion or dislodgment of the loops by the pulling or drawing of them out of or away from the ground. The invention is not only applicable to other forms of loose pile weaves, with variations in warp and weft number, arrangement and interweaving, but it is also adaptable to different forms of fast pile weaves as shown in one form in Fig. 3 inwhich the pile yarn is so interlaced with the weft threads aspto tend to prevent the pile loops from pulling out or away from the ground or losing height. In all these weaves an important novel feature of the invention resides in the definite, precise, and permanent warp-wise disposition of the pile loops and in their resistance to distortion or dislodgment.

It may additionally be noted that, by varying the size or count and number of threads, and by changing the height of the gauges or using gauges of differing heights, the width and height of all or some of the pile loops can be varied with corresponding modification in the surface effect. Likewise, the size, material composition, visual finish and twist of the yarns or threads may be changed or modified to suit the requirements in hand, as natural and artificial yarns, including, both animal and vegetable fibers or fllments, may be employed to advantage under different circumstances.

It will be understood that furious changes may be resorted to in the form, construction, arrangement and material of the various elements, without departing from the spirit and scope of my invention; hence I do not intend to be limited to the details herein shown and described except as they may be included in the claims.
