Pectin-degrading enzymes for scouring cotton
1998
Hartzell, M.M. | Hsieh, Y.L.
In our previous study, a pectinase was found to improve the surface wetting properties of greige cotton fabrics following a water pretreatment at 100 degrees C. This study further evaluated seven pectin-degrading enzymes, i.e., four pectinases, two pectinesterases, and a pectin lyase, for scouring raw cotton fabrics. Three of the pectinases significantly improved the wettability of cotton fabrics following a 100 degrees C water pretreatment to the same extent as alkaline scouring. The other pectinase, pectinesterases and pectin lyase had no beneficial effects on improving the wettability of raw cotton fabrics. Reaction conditions for the three pectinase treatments were optimized in respect to temperature, concentration, pH, and time. The pectinase treated fabrics did not exhibit additional shrinkage, color change, nor significant strength loss from the fabrics pretreated in water at 100 degrees C.
