FIELD: tobacco industry.
SUBSTANCE: method for producing a lyocell material includes spinning at 100-110°C a lyocell spinning solution containing cellulose pulp and the aqueous solution of N-methylmorpholine-N-oxide, in which the pulp concentration is 8-11 wt %. The spun lyocell solution is coagulated to produce coagulated lyocell multifilament yarn. The lyocell multifilament yarn is washed with water, treated with oil and dried. The lyocell multifilament yarn is then corrugated to produce a corrugated tow having a tensile strength of 1-2 g/den.
EFFECT: providing the production of a lyocell material for a cigarette filter with low strength, which contributes to its biodegradation, increasing the efficiency of the process of manufacturing cigarette filters.
