Producing polymer from bamboo based on the ultrasonic-laccase system was mainly focused,and explored its application on textile industry.Laccase was used to catalyze the original bamboo extraction after boiling pretreatment through ultrasonic bath and ultrasonic probe respectively.The results shown that the residual enzyme activities of ultrasonic probe and ultrasonic bath treated for 120min decreased to 82% and 83.75% of the initial value,remaining a high value of the enzyme activity.Compared with the original bamboo extraction,the OH content in the laccase-catalyzed polymeric liquids decreased significantly with an obvious color changes after reaction.The 1H-NMR test indicated that the aromatic peak and the allyl/OH peak regions were obviously weakened or disappeared,confirming an efficient polymerization of the extracts.The polymers obtained had a certain dyeing effect on the cotton and wool fabric,and subsequent research can be further optimized to enhance the polymerization effect and improve its practical textile application.
