Rexine - a strong, coated cloth, usually in the form of an imitation leather.
Types of rexine:
Rexine-15
Rexine-17
The way it's made:
The weave and composition of the base (gray) cloth depend on the grade of cloth being manufactured at the time, and may be cotton or a cotton and rayon mixture. The cellulose nitrate coating is colored by mixing powdered pigments with synthetic oils and is applied in several layers, each being dried before the next application. Polyvinyl chloride may also be used for the coating. Embossing is done with engraved steel rollers, usually to imitate the grain pattern of a leather, but sometimes with modern geometric designs. This type of cloth has been in use since the first decades of the 20th century.
Products:
Mostly used as a covering material for books, such as Bibles and other. Some other products include binding materials, bags, wallets.
