METHOD OF PRODUCING ORNALIENTAL FABRIC Camille Dreyfus, New York, N. Y., and Herbert Platt, Cumberland, Md., assignors to Celanese Corporation of America, a corporation of Dela-1 ware No Drawing. Application December 20, 1928,

Serial No. 327,471 1 5 Claims. (Cl. 28-1) This invention relates to the preparation of warp consisting wholly of one kind of yarn and fabrics containing yarns of organic derivatives of a weft consisting wholly of another kind of yarn, cellulose having on at least a part of the surface will not produce the desired result, since on the J thereof a pebble or cockle effect produced by shrinking of the one kind of yarn, say the weft,

A solution of 10 of one kind of yarn and not of the other. Other nitric acid causes yarn of organic derivatives objects of our invention will appear from the of cellulose such as cellulose acetate to shrink, following detailed description. while it does notcause yarns of cotton, reconsti- In accordance with our invention, we produce tuted cellulose, silk or wool to shrink.

thus enhancing the ornamental eflect. It reconstituted cellulose yarn (rayon) is substituted for the cotton yarn in .the above fabric, similar results are obtained.

- The term alternating" as. used in the appended claims is intended to include arranging the yarns in any regular or irregular manner.

It is to be understood that the. foregoing detailed description is given merely by way of illustration, and that manyvariations may be made therein without departing from the spirit or our invention.

Having described our invention, what we claim and desire to secure by Letters Patent is:
