rexine
A strong, coated cloth, usually in the form of an
imitation leather, and used as a covering material
for books. 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.
