Method for improving enzymatic degumming efficiency of flax raw stems by ultrasonic and alternating electric field synergy
This application provides a method for improving the enzymatic degumming efficiency of flax stems through the synergistic effect of ultrasound and alternating current (AC) electric field, belonging to the field of textile materials technology. The method involves immersing flax stems in a composite enzyme solution, applying an AC electric field and an ultrasonic field, with the AC and ultrasonic fields continuously alternating, and finally inactivating the enzyme to obtain flax fibers. The ultrasonic power density is 0.1 W / mL–2.0 W / mL, and the AC electric field strength is 1 V / cm–5 V / cm. This method achieves this through the synergistic effect of a low-voltage AC electric field and an ultrasonic field. The low-voltage AC electric field activates enzyme activity without inactivating it, while the ultrasonic field removes the gums degraded by the reactivated enzyme solution. Furthermore, the low-power-density ultrasonic field enhances enzyme activity with minimal damage. This synergistic effect improves the efficiency of the flax fiber enzymatic hydrolysis process and maintains the fiber strength of the flax fibers.
