Smoke filter material and use thereof

A method for preparing a cellulose acetate fiber rod is provided, which is characterized by blooming a tow composed of cellulose acetate fibers, adding to or coating on the bloomed tow from 1 to 20 percent by weight (based on the weight of the cellulose acetate fibers) of a plasticizer comprising 1,4-butanediol diacetate, and gathering and curing the resulting cellulose acetate fibers at much higher speed than is possible in the conventional methods to form a cigarette filter rod which does not harm cigarette flavor and smoking taste.
