Glycolic
Acid is ideal for use in the leather industry where
grain is important and high quality desired. In
tanning, it is extremely efficient for bath pH adjustment,
particularly in the production of sole leather and
other vegetable tannings. Its sodium salt is effective
as a masking agent. In deliming, Glycolic Acid penetrates
hides rapidly, frequently reducing operations time.
It improves grain quality by eliminating excessive
pelt swelling that can cause wrinkles and reduce
tear resistance. In pickling, Glycolic Acid forms
metal complexes with chrome and alum mordants which
are beneficial in both fur and leather finishing.
In dyeing, Glycolic Acid requires lower usage than
volatile agents like acetic acid. There are no corrosive
fumes upon heating and maintenance of pH levels
is made easier. |
