Acid Cellulase Enzymes, Effect of: Top Loading Washe
Year: 2013
Abstract: Purpose and Scope
This test method provides a simple testing procedure to evaluate the effect of acid cellulase enzymes on cellulosics by laundering.
The evaluations are carried out as listed in Section 8.
Other cellulase enzymes, i.e., modified acid and neutral types, may be evaluated by this test procedure. However, the concentration, pH, and time should be followed as recommended by the enzyme supplier.
A specific concentration of enzyme, buffer, and detergent are required in the bath to achieve the desired improvements. Since this test method utilizes an automatic washing machine to simulate the action of rotary drum machines, paddle machines, or jets used in production type operations (that usually operate at low liquor ratios), the concentrations required in this test method are based on grams/liter (g/L), to compensate for the difference in liquor ratios.
