“…22c). During spinning of the cellulose fiber from NMMO solutions, there appears a crystalline phase in which long crystallites are extended in the longitudinal direction [16][17][18]. On the one hand, this situation indicates on high order and increased density of the structure being formed.…”

“…Dissolution of cellulose starts with monohydrate (water content 13.3% and T m ~80 °C). The use of NMMO as a direct solvent of cellulose and its mixtures with polyesters and polyamides is described in numerous publications (see, for example, [ 6 , 11 , 12 , 13 ]). As an illustration of the dissolution of cellulose in NMMO, a schematic representation of the interaction stages of the solvent with the polymer is presented in Figure 2 .…”

Replacing the aqueous coagulation bath with an alcoholic one during spinning cellulose fibers (films) from solutions in N-methylmorpholine-N-oxide leads to a radical restructuring of the hydrogen bonds net of cellulose and, as a result, to a change in the structure and properties of the resulting material. By the method of optical interferometry, it was possible to identify the intrinsic features of the interaction of the solvent and isomeric alcohols and to construct phase diagrams of binary systems describing the crystalline equilibrium. Knowledge of the phase states of the system at different temperatures renders it possible to exclude the process of solvent crystallization and conduct the spinning in pseudo-homogeneous conditions. The structure and morphology of samples were studied using X-ray diffraction and scanning electron microscopy methods for a specific coagulant. When the solution under certain conditions is coagulated at contact with alcohol, the solvent may be in a glassy state, whereas, when at coagulation in water, an amorphous-crystalline structure is formed. The structural features of cellulose films obtained by coagulation of solutions with water and alcohols help to select potential engineering or functional materials (textile, packaging, membranes, etc.), in which their qualities will manifest to the best extent.
