Targeting bath exhaustion, Yuan et

Targeting bath exhaustion, Yuan et al. (2008) and
Parvinzadeh (2007) applied proteolytic enzymes in
the wet finishing of leather and in the pre-dyeing and
dyeing of wool. The authors reported improvements
in properties such as the affinity to the dye, bath
exhaustion, uniformity of color, dye penetration into
the hide, wettability of the fiber, dye absorption,
reduced shrinkage and improved tension in stretch
wool fibers.
In studies related to waste treatment, enzymes
were applied in the recovery of chromium and
proteins from tanned cuttings (Cantera et al. (2002);
Kolomaznik et al. (2008); Jian et al. (2008); Amaral
et al. (2008); Gutterres et al. (2009)) and in the
production of collagen hydrolysates from untanned
cuttings (Bajza (2001).
In this study, several commercially available
enzymes specific for the leather sector were tested in
the soaking and unhairing/liming processes. Eleven
soaking tests (3 control and 8 experimental tests) and
six unhairing/liming tests (2 control and 4 experimental
tests) were carried out to evaluate the enzymatic
action of five enzymes and to quantify the levels of
total organic carbon and soluble protein in the
residual baths. The formulations used in the tests
were based on the work of Souza et al. (2010). In
addition, the enzymatic activity on collagen, keratin
and lipids was determined. Finally, SEM images of
the hides were acquired for the coenzymatic and
control tests.
