UNITED STATES PATENT OFFICE ABRAHAM UNGER, OF NEW YORK, N. Y., ASSIGNOR TO CONCORD CHEN'ILLE COMPANY, INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK PROCESS OF MAKING FABRICS Application filed September 13, 1932. Serial No. 632,957.

This invention relates to a process of making fabrics, and is particularly applicable to a process of producing-imitation furs.

It is well known that imitation furs which simulate Persian lamb or astrakhan can be made by laying out into suitable designs a yarn or strand of material, and then attaching the material to a suitable backing. Such imitation furs. however, have up to the present time been almost exclusively made by knitting the yarn or strand of material to the backing. Another way of simulating fur is to thread the yarn or strand upon needle like wire threads to form a design and then attach the material so layed out to a backing.

These methods all have the disadvantage of being slow and costly. A further disadvantage is that, the sharp points of the needles or fine wire threads may cause skin infections and thus prove dangerous to the operator.

The present invention provides a process of making fabrics which is not only less expensive and quicker in operation than prlor methods but also highly efiicient and safe for the operator.

More particularly, the invention discards altogether the use of needles or fine wire threads in the process of making fabrics, and, instead, utilizes suction to hold the yarn or strands of material in place until fastened to a suitable backing. This backing, which may comprise any desired material, is attached to the yarn or strands by means of an adhesive such as glue or cement. The resulting fabric product may then, if desired,

be subjected to a slight pressure to insure an even attachment of the strands to the back- The accompanying drawing shows one particular manner of practicing the present invention. In this drawing there is illustrated a box-like container 3 of any desired form which has its upper side consisting of a thin metallic screen 2 provided with numerous closely adjacent air holes 4. A blower or suction device 5 connects with the container 3 over pipe 6 and is arranged, when in operation, to suck air through the perforated screen. The latter, of course although herein designated as metal is not limited thereto since it may be made of any suitable material in various shapes and formsto permit entrance of air into container 3 through apertures sufliciently close to insure the desired effect on the strand material.

Placed upon screen 2 is a yarn or strand of any material 1, such as chenille, which is laid out by hand or in any other Way in accordance with a design to imitate fur. This material, for very obvious reasons, remains in the position in which it is placed While the suction pump is functioning, as the design is formed on the screen.

Suction pump 5 may be any desired type of apparatus.

If desired, container3 may be divided into sections, and individual suction connections run into the individual sections. Further, the container may be inclined at any desired degree.

In order to secure the chenille to a backing, an adhesive is first applied to the backing after which the latter is placed directly in contact with the chenille on the screen. Suction is then removed from that portion of the screen upon which the chenille is placed preferably by valve action, while the chenille secured backing is taken ofi' the screen to dry completely. The fabric product may now be passed through'rollers for the application of a slight pressure'the'reto-in order to insure a very even attachment .of the chenille to the backing.

Although one particular process has been described in detail in connection with a process of making imitation furs, it is to be distinctly understood that this invention is not limited thereto, since the principles thereand are not to be construed as limitations are wool, cotton, silk (both natural and artificial) fibne paper, or combinations of these.

at is c aimed is 1 1. The process of making a fabric which includes the steps of supporting by suction a yarn or strand material laid out according to a design, and attaching a suitable backing to said material.

2. The process of making a fabric which comprises the steps of placing a strand or yarn material against a support, holding said material a ainst said support by suction, and subsequent y fastening said material to a suitable backing.

3. The process of making a fabric which comprises the steps of laying a strand or yarn material upon a screen according to a design, applying suction through said screen to mamtain the position of said material in said design, and fastening said material to a suitable backing.

4. The process of making imitation fur which comprises the steps of laying chenille upon a screen according to a design, applying suction to said chenille through said screen, and subsequently cementing or gluing said chenille to a suitable backing.

5. The process of making imitation fur which comprises the steps of laying chenille upon a support in accordance with a predetermined design, applying suction to maintain the position of said chenille in said design, cementing said chenille to a suitable backing, removing said suction and subsequently applying a pressure to said chenille and backing.
