In research programme realized was carried out analysis of the properties of the spinning solutions of cellulose in NMMO-H2O system. Based on theological properties of cellulose solutions and measurements useing FTIR and NMR methods was confirm that liquid crystals of cellulose appear in NMMO-H2O system. Liquid crystal phenomena was observed not only in the high concentrated cellulose solutions in stationary state but also in cellulose solutions in dynamic state when spinning cellulose solutions flow across spinneret hole. In this last case existence of the liquid crystals in stimulated by preasure and ingredients.
