Stonewashing with pumice stones
started out closely as it sounds: fabric was washed with stones. By the
development of cellulases, stonewashing implicated a lot of pumice rock plummeting
around in a washer amid denim garments. As the advance of cellulase, the
stonewashing succession time has been slash in half when used in combination
with pumice stones. In addition, stonewashing with cellulase is higher to
washing with pumice alone as it increases garment softness and outcome in
higher levels of fabric abrasion.
Whilst initially developed,
cellulase was an acid enzyme with a pH level of about 5. Acid cellulase is destructive,
and although it produces high levels of abrasion, it also reduces the fabric’s
tensile power and outcome in a high quantity of re-deposition, or back staining.
Neutral cellulase with a distinctive
pH of 6.5 – does not decrease the fabric’s tensile strength or back stain as strictly
as acid cellulase does. However, neutral cellulase is not as destructive as
acid cellulase and usually commands a higher market price.

Agrochem’s neutral cellulase enzymes provide unique attributes, as well as
brightness and contrast, to denim wash.
