| titleOfInvention | Para-type wholly aromatic polyamide fiber and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a para-type wholly aromatic polyamide fiber having an irregular cross section, which has large and uniform irregularities in its cross section. SOLUTION: The cross section of a discharge hole for discharging a polymer solution has a convex portion and a concave portion, and the ratio L1 / L1 of the width L1 of the convex portion on the outer peripheral side of the discharge hole to the width L2 of the convex portion on the central side of the discharge hole. L2 is not less than 1.5, the length L3 from the outer peripheral side of the discharge hole of the convex portion to the center side of the discharge hole of the convex portion, and the maximum inscribed in the polygon obtained by connecting the centers of all the concave portions with straight lines. The polymer solution is discharged using a discharge hole having a ratio L3 / L4 of 3.0 or more with respect to the diameter L4 of the circle. [Selection diagram] Fig. 1 |
