Abstract:
... Polydisperse fiber networks are the basis of many natural and manufactured structures, ranging from high-performance biobased materials to components of living cells and tissues. The formation and behavior of such networks are given by fiber properties such as length and stiffness as well as the number density and fiber–fiber interactions. Studies of fiber network behavior, such as connectivity or ...

Abstract:
... Traditional degumming of bast fibers results in problems such as environmental pollution and inferior fiber quality. For these reasons, biodegumming was considered as a potential process for bast fibers. In biodegumming process, decomposition of noncellulosic components was the pivotal problem. In this manuscript, the bast fiber of Apocynum venetum was processed with combinatorial processing, cont ...
