Process-Induced Microstructure in Viscose and Lyocell …
WEBApr 1, 2021 · Viscose and lyocell fibers are characterized by partially oriented semicrystalline microstructure. We present a methodology to calculate the Lorentz correction for such microstructure and employ this to analyze the lamellar scattering from viscose fibers using a 1D correlation function approach.
