Surface Modifier
Biological finishing agents remove protruding micro-fibrils from the surface of cellulosic fabrics to create a smooth and clean appearance. Bio-polishing cellulase acts as a catalyst that targets and weakens these fuzzy fibres so they break away during mechanical agitation in the wash cycle. This treatment replaces harsh chemical singeing for high-end knitwear.
Substrate Digestion
The enzyme binds to the amorphous regions of the cellulose and breaks the molecular bonds to detach surface hairiness. While bio-polishing cellulase improves the hand feel and prevents pilling, it also causes a slight loss in fabric weight and bursting strength. Technicians must balance the desired smoothness against the potential for excessive degradation of the primary fabric structure.
Monitoring the treatment time prevents the loss of tensile integrity.
Pilling Resistance
Finished garments show a reduced tendency to form pills after repeated domestic laundering.
Industrial Verification
Evaluation of the result occurs through weight loss measurements and pilling tests like the Martindale or pilling box method. A typical weight loss of three to five percent indicates a thorough surface clearing without compromising the durability of the base material. Excessive loss suggests the reaction time was too long or the enzyme concentration was too high.
