FIELD: smoking accessories.
SUBSTANCE: invention relates to a lyocell material for a tobacco filter and a method for manufacturing thereof. Said method for manufacturing a lyocell material comprises spinning of lyocell spinning solution, comprising cellulose pulp and an aqueous solution of N-methylmorpholine-N-oxide. Then, the spinning solution is coagulated to produce lyocell multifilament fibers. Next, fibers are washed with water, lubricated with oil and twisted to produce a twisted bundle. Multifilament yarn comprises a monofilament with a modified cross-section.
EFFECT: method provides lyocell monofilament with increased surface area that is highly biodegradable.
