摘要: This invention provides cellulose ester fibers having an intermediate degree of substitution per anhydroglucose unit (DS/AGU) along with pigments which act as photooxidation catalysts. The fibers are useful as filter materials for tobacco products. The filter materials thus provided are easily dispersible and biodegradable and do not persist in the environment.
