FABRIC BEARING DESIGN IN RELIEF.

Application filed August 16, 1922. Serial No. 582,329.

To all whom it may concern:

Be it known that I, AUcUs'r F. SCHRAMM,

Jr., a citizen of the United States, a resident of Richmond Hill, L. 1., in the county of Queens and State of New York, have invented certain new and useful Fabric Bearing Designs in Relief, of which the following is a specification.

This invention relates to a fabric bearing 1 design in relief and an improved method for making such fabric.

The invention in its preferred form is shown in the accompanying drawings in which- Figure 1 illustrates a piece of muslin, the upper left hand corner of which has been provided with a nap;

Fig. 2 represents a section of the muslin with the nap over the entire surface of one no side;

Fig. 3 represents the muslin of Fig. 2 after it has been rolled between pressure rollers bearing a suitable design which is imparted to the muslin, and

Fig. 4 is an enlarged section on line 44 of Fig. 3 showing the approximate relations between the fabric, the outstanding nap, and the depressed or compressed portions of the na Th said drawings the muslin is represented by the numeral 1 and the nap by the numeral 2. The na is made on the fabric by the use of a suitable picking machine which picks up from the surface of the muslin the short fibers to provide a nap on the main body of the fabric, this operation be ing well known in the art. After the nap is thus provided, the other side of the fabric is impregnated with. a gum which is nonco hygroscopic and which is plastic when heated. The gum solution is allowed to penetrate until is reaches the nap so that when the muslin fabric is compressed between the rollers the depressed or compressed portions of the nap will be glued down to the base of the fabric and will not therefore be able to resume their former position. The rollers employed are preferably internally heated so that the gum will become so plastic and flow sufficiently to eiiiciently glue down the depressed portions ot'the nap. It is not desirable to allow the gum to penetrate any further so that it would be absorbed by the portions of the nap not depressed by the rollers. The latter may be of any construction such as embossed rollers or rollers provided with designs in relief or etched designs.

As a result of this operation there is imparted to the muslin fabric a design such as @0 shown in Fig. 3 in which numeral 3 designates the original nap or pile and numeral 4 designates the compressed or depressed portions of the original nap which are now firmly held down against the body of the fabric by the glue and by the effects of the pressure. In Fig. 4 which is an enlarged section of Fig. 3, numerals 3 at the left show the original nap which has been given a corduroy-like effect by compressing the i0 portions designated by the numerals 5 along narrow lines as shown in Fig. 3. The circular embossments 6 appearing in Figures 3 and 4 have depressed areas 7 of the nap lying between them. The portions des-' 25 ignated by numerals 7 in Fig. 4 are the same as portions 4 in Fig. 3. The depressed portions of the nap will not resume their original positions again under adverse con ditions such as humid weather or dampness so of the fabric because they are glued down by a non-hygroscopic glue. They are therefore permanently fixed to the fabric as the result of the compression.

While in the above embodiment the treatment of a muslin fabric has been described, it is to be understood that the same method may be applied to many other fabrics and fabric-like materials capable. of receiving embossing by creating depressions and elevations. Thus velours, velvets and velvet-like materials having a pile as forv example pile velvet or corduroy may be treated in a similar manner to provide a permanent design in relief. Fabrics and similar materials which have a natural nap or a natural pile may be thus treated without the preliminary operation of picking out a nap from the material. Cotton goods, linen, wool, and in fact various animal and vegetable fabric material may be subjected to the above'described process. The process may be varied by first providing an artificial nap or pile on the paper or similar material and then glueing and running through the rollers. Besides these modifi-. cations others will suggest themselves in which it is desired to provide designs in relief by creating depressions in any suitable manner and securely fixing these depressions to the base portion of the material by a suitable glue equivalent to the one above pressed portions to rise again when dampened or released from their depressed positions. Articles which are not thus treated with the gum will have a strong tendency to blur the design after a lapse of time or during humid weather because of the raising up of the depressed portions of the nap and these depressed portions would of course not resume their depressed positions again and would therefore completely ruin the efiect of the design. My invention therefore provides a very superior article of manufacture which may be used for dress goods, wall paper, ornamental draperies, linings, and many other purposes.

The gum or glue above referred to may advantageously consist of the following composition: A thin solution of unvulcanized rubber in gasoline or mineral naphtha, about 20%, rosin about 5%, and gasoline or mineral naphthaabout 75%. 'lhese proportions may vary, for example, the rosin may be as low as about 1% or as high as 10% but such high amounts are likely to render the goods too stiff; the rubber solution may also vary considerably, e. g.,.it may amount to 33%. The solvents may be replaced by others, e. g, chloroform, carbon tetrachloride, benzol, carbon disulfid, ether, oil of turpentine, and other rubber solvents. ft is desired to limit the proportions so as not to make the fabric stifi', harsh, or rough; it should preferably have a soft feel and the amount of gum should accordingly be keptas low as possible.

The above gums are Waterproof and nonhygroscopic and will therefore permanently hold the depressed nap down. However, in certain cases, water-soluble gums may be used such as Calcutta elastic gum which is classed as a cold water gum; This will hold the nap down fairly well. Other gums or glues may be used according to the class of goods being treated. It is preferable that the gum be non-hygroscopic, non-odorous, and colorless, and that it will not impart harshness or stifiness to the fabrics.

As many apparently widely difierent embodiments of this invention may be made without departing from the spirit thereof,-

- incense thereof being permanently fixed to the fabric base.

9. The improvement in the method of manufacturing fabrics bearing designs in relief in which a fabric provided with a nap is rolled between compression rollers carrying suitable designs, characterized by applying a non-hygroscopic adhesive material to the reverse side of the fabric before the rolling operation.

10. The improvement in the method of manufacturing fabrics bearing designs in relief in which a fabric provided with a nap is rolled between compression rollers carrying suitable designs, characterized by applying a non-hygroscopic adhesive material to the reverse side of the fabric prior to the rolling operation, said adhesive being plastic when heated, and said rollers being sufliciently heated to render the adhesive plastic.

In testimony that I claim the foregoing, l have hereunto set my hand this 15 day of August, 1922.
