Abstract
The fiber cross-section of an island-in-a-sea composite fiber perpendicular to the fiber axis, the island component and sea component are arranged such that the sea component surrounds the island components. The composite cross-section is very consistent, and the fiber has excellent post-processibility. The island-in-a-sea composite fiber wherein diameter of the island component is 10 to 1000 nm, variation of the island component diameter is 1.0 to 20.0%, modification ratio is 1.00 to 1.10, and variation of the modification ratio is 1.0 to 10.0%.
