Document Type and Number:
WIPO Patent Application WO/2022/219743
Kind Code:
A1
Abstract:
A method for manufacturing short fibers according to the present invention comprises: an entanglement alleviating step in which tension is applied in a predetermined conveyance direction to a tow band that is conveyed in the conveyance direction, contains crimped cellulose acetate fibers, and has moisture added thereto, thereby alleviating entanglement of the crimped cellulose acetate fibers in the tow ban; and a short fiber forming step in which the tow band with alleviated entanglement is cut to form short fibers.
