aldehyde tanning
Essentially a formaldehyde tannage. Several
aldehydes react with hide protein to prevent
putrefaction, but onlyFORMALDEHYDE has been
used to any extent in the manufacture of leather.
Formaldehyde is soluble in water, the resultant
solution generally being known as FORMALIN . Aldehyde
tanning is used principally in tanning white,
washable leathers, usually sheep or lambskins,
with the grain split or shaved off. Such leathers
are seldom used in bookbinding. See also: ZIRCONIUM TANNING .
