acid-free leather
Ostensibly, leather manufactured without the use
of acids, but interpreted by most producers to
mean leather from which as much acid as possible
has been removed. The removal of acid used in
producing leather is a costly and time-consuming
process, and calls for repeated washing of the
stock. Tanning agents which contain a relatively
high amount of salts of weak acids, of which MYRABOLANS is one,
are said to protect leather against acids used in
manufacture or those absorbed from the atmosphere.
