DEFINITION

Classification: 8/118

(under subclass 116.1) Processes and compositions wherein cellulose fibrous material or paper is subjected to a treatment with gelatinizing or swelling agent, such as ZnC12, H2 SO4, etc., to impart a parchment-like, linen, transparent or translucent finish thereto. This may result in an increased resistance to water or grease and the like. The fabric generally becomes stiff or transparent. However, softening agents may be included as part of the process. The material may be previously or subsequently mercerized by means of alkali metal hydroxides or the like. So-called "organdie" effects and the delustering or relustering of these materials by a gelatinization process is included herein. The selvaging of the edges of a fabric to prevent raveling, by the process herein defined, is also included.
