Importance of the Phase Diagram in Lyocell Fiber Spinning

Abstract

The lyocell fiber is become very popular in the recent time among the researcher due to its higher strength, rigid crystalline morphology and its proximity towards to cotton. Lyocell fiber gives higher mechanical modulus which substantially makes it an effective material for use in different biometerials, paper industry, nonwoven fabric or even in packaging purpose. The spinning of this kind of fiber is very challenging due to its several composite steps like-NMMO preparation (raw material), preparation of a proper solvent phase of NMMO-water system, spin extrusion etc. we can improve the quality and sustainability of this fiber product by a suitable judgment of the phase diagram of the spinning system (charge) and also increase in production.
