Abstract:
An overview is given of what is known in literature concerning the structure of both cellulose and cellulase enzymes and the enzymatic degradation of cellulose. Based on this knowledge, a hypothesis is formulated about the relation between cellulase performance and required applied shear force on the fabric. In short, the specific cellulase activity is highest on the flexible amorphous cellulose when compared to that with the more rigid crystalline cellulose. When applying cellulase activity on damaged, fuzzy fabric, the connection point of cellulose material oriented away from the fiber axis, which is partly amorphous due to the damage, will be turned again to a more rigid, mainly crystalline structure. Due to this shift, this connection point will function as a primary point of application for shear force, resulting in removal of the fuzz.
