Title:
CELLULOSE ACETATE FIBER, CELLULOSE ACETATE TOW BAND, AND METHOD FOR MANUFACTURING CELLULOSE ACETATE TOW BAND
Document Type and Number:
WIPO Patent Application WO/2020/035901
Kind Code:
A1
Abstract:
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.
