Embodiment Construction
[0015] The invention relates to a degumming process for preparing textile fibers using mulberry bark as a raw material, which is characterized in that the mulberry bark fibers are degummed by an enzyme treatment method, and the main process steps are as follows:
[0016] Mulberry natural treatment - microwave treatment - mechanical beating to remove impurities - acid leaching pretreatment - alkali neutralization - alkaline pectinase treatment - lye scouring - water washing - cellulase treatment - Bleach - wash - dry.
[0017] Each step of the process is described in detail below:
[0018] 1. Natural treatment of mulberry bark:
[0019] After the mulberry bark is collected, it is weathered by the sun and supplemented by mechanical beating to remove most of the wax and part of the outer skin and reduce the pressure of degumming. Then put it at normal temperature for natural moisture absorption aging treatment, and the treatment time is 2 to 5 hours.
[0020] 2. Microwave heat...
