Filter tow and method of manufacturing the same, and cigarette smoking filter element and method of manufacturing the same |
| abstract |
(57) [Summary] (Modified) [Objective] To provide a method for producing a filter tow containing cellulose acetate filaments and / or cellulose acetate staple fibers, which exhibits excellent biodegradability. [Structure] A filter tow composed of cellulose acetate filaments and / or cellulose acetate staple fibers, At least the surface of the filaments and staple fibers has a cellulose acetate with an acetyl number of less than 53%, preferably less than 49%. The method of making the present filter tow comprises spinning cellulose acetate filaments from a cellulose acetate solution having an acetyl number of at least 53% in acetone, cutting said filaments into staple fibers if necessary, mixing said filaments and / or staple fibers. The filaments and staple fibers have at least 5% of cellulose acetate on their surface. It is hydrolyzed to an acetyl number of less than 3%, preferably less than 49%. |
