Document Type and Number:
WIPO Patent Application WO/2020/101002
Kind Code:
A1
Abstract:
The present invention relates to ultrafine fibers each having a fiber diameter (D) of 100 to 5000 nm and a ratio (L/D) of the fiber length (L) to the fiber diameter (D) of 3000 to 6000, and containing carboxyl terminal groups in an amount of 40 eq/ton or more. The ultrafine fibers according to the present invention cannot be aggregated in a water-based medium and can surely have excellent uniform dispersibility.
