CELLULOSE ACETATE FIBER, CELLULOSE ACETATE TOW BAND, AND METHOD FOR MANUFACTURING CELLULOSE ACETATE TOW BAND

摘要

The purpose of the present invention is to suppress a decrease in airflow resistance of a cellulose acetate tow band obtained from cellulose acetate that contains no or little titanium dioxide but can prevent spinning holes from clogging with the lapse of spinning time. A cellulose acetate fiber that contains 0.05 wt% or less of titanium dioxide and 0.05-1 wt% inclusive of at least one kind of a metal oxide selected from the group consisting of Fe₃O₄, Fe₂O₃, MnO₂, Cr₂O₃, Cr₂CuO₄, NiO, Sb₂O₃ and CoAl₂O₄.
