AI Technical Summary

Technical Problem

Existing enzymatic degumming technologies for bamboo fiber suffer from problems such as high energy consumption, long reaction time, uncontrollable reaction termination, and fluctuations in fiber properties. There is a lack of systematic solutions for efficient degumming and reaction control under low-temperature conditions.

Method used

Thermosensitive enzyme preparations, including pectinase, hemicellulase, xylanase, and thermosensitive response modifiers, are used to achieve controllable termination of the degumming reaction by maintaining high enzyme activity at low temperatures and inactivating the enzyme preparations when the temperature rises, thereby reducing energy consumption and improving process stability.

Benefits of technology

Achieving efficient degumming under low-temperature conditions significantly reduces energy consumption, improves process stability and fiber performance, and ensures degumming efficiency and fiber integrity.

Abstract

The application relates to the technical field of bamboo fiber biological degumming, and provides an application process of a low-energy-consumption temperature-sensitive enzyme preparation for bamboo fiber degumming. The process adopts a temperature-sensitive enzyme preparation containing pectinase, hemicellulase, xylanase and a temperature-sensitive response regulator, carries out a degumming reaction on bamboo fiber under low-temperature conditions of 30-40 DEG C, makes the enzyme preparation maintain high enzyme activity to realize efficient degumming, when the reaction reaches a predetermined degree, the temperature is increased to not less than 50 DEG C to trigger the phase transition of the temperature-sensitive response regulator, the enzyme preparation is rapidly inactivated, and therefore the degumming reaction can be controllably terminated. The process avoids the problems of high energy consumption and fiber damage caused by traditional medium-high-temperature enzyme methods or long-time reaction, can ensure the degumming effect and fiber performance stability, and can control the energy consumption of unit mass bamboo fiber at a low level.
