[0002] Papermaking pulping is a complex process involving multiple steps. Its core purpose is to separate fibers from plant fiber raw materials to obtain pulp suitable for papermaking. In recent years, bio-pulping technology has emerged. This is a composite process that mainly relies on biological decomposition and combines various physical and mechanical decompositions.
