  • Title: The application of ultrasound and enzymes in textile processing of greige cotton.
    Author: Easson M, Condon B, Villalpando A, Chang S.
    Journal: Ultrasonics; 2018 Mar; 84():223-233. PubMed ID: 29161619.
    Abstract:
    A review is reported herein of the research progress made at the USDA's Southern Regional Research Center to provide an ultrasound and enzymatic alternative to the current textile processing method of scouring greige cotton textile with caustic chemicals. The review covers early efforts to measure pectin and wax removal from greige cotton textiles using standard wicking methodology and further describes an investigation of newly discovered polygalacturonase enzymes as bioscouring agents. Additional research is reviewed involving efforts to characterize and optimize the ultrasound-enhanced enzymatic scouring process through a statistical examination of the operating parameters of power, enzyme concentration, ultrasonic frequency and time.
