Abstract
1. Technical Result Increase in filter selectivity and reduction of the bacterial destruction term. 2. Essence Making of a braid from cellulose acetate by extrusion of spinning solution, which besides cellulose acetate (2,5) and the solvent contains additives destructing the filter, which are difficult to dissolve in the spinning solution, the quantity of which makes 0,1-5 mass %, on conversion to cellulose acetate 2,5. 3. Field of application Tobacco production.
