STRUCTURAL MATERIAL FORMED OF CELLULOSE ACETATE, USE THEREOF IN PRODUCING FILTER TOW, USE OF SAID FILTER TOW IN PRODUCING TABACCO SMOKING FILTER ELEMENT, SAID FILTER TOW AND SAID TABACCO SMOKING FILTER ELEMENT

摘要

PURPOSE: To provide the production of this structure which is formed from cellulose acetate and suitable as a product capable of being mass-produced and shows excellent biodegradability under the influence of environment. CONSTITUTION: This structure is formed from cellulose acetate on the inside or surface of which an additive exists, wherein the additive consists of a nitrogen-containing organic compound that forms by its degradation due to microorganisms, a basic decomposition product, particularly a basic compound having ammonia, at least one NH group and/or at least one NH2 group. The structure can be formed in a filament-, staple fiber-, film-, foil-, sheet- or other object-form. Such a structure in a filament- and/or staple fiber-form(s) can be used for producing filter tow. This kind of filter tow can be used for manufacturing a tobacco smoking filter element.
