SEA-ISLAND COMPOSITE FIBER COMPOSITE ULTRA-FINE FIBER AND FIBER PRODUCT

摘要

In the cross-section of the fiber, in the island-in-the-sea composite fiber arranged so that island components are interspersed in the sea component, the island component has a composite form formed by bonding two or more different polymers, the length L of the junction of the island component and the diameter of the composite island component Sea-island composite fiber with a ratio of D to L/D of 0.1 to 10.0. Since it is a sea-island composite fiber with good high-order processability, high productivity and quality can be maintained with existing equipment, and the ultrafine fiber obtained by removing sea components has an excellent tactile feel while providing a sea-island composite fiber with functions such as shape control do.
