Title:
COAGULATED YARN AND MANUFACTURING METHOD THEREOF, CARBON FIBER PRECURSOR FIBER, AND METHOD FOR MANUFACTURING CARBON FIBER
Document Type and Number:
WIPO Patent Application WO/2018/047692
Kind Code:
A1
Abstract:
Provided are a coagulated yarn for obtaining carbon fiber having high strength, a carbon fiber precursor fiber using same, and carbon fiber using same. The coagulated yarn, which is used for manufacturing carbon fiber, is a coagulated yarn the surface hole diameter of which is 30 nm or less and the degree of swelling is less than 100% or a coagulated yarn the surface hole diameter of which is 30 nm or less and the inner hole diameter is 30 nm or less. The carbon fiber precursor fiber and the carbon fiber are obtained using such a coagulated yarn.
