Sea islands fiber |
摘要 |
An islands-in-sea fiber includes island components and a sea component arranged to surround the island components, wherein the island components and the sea component are composed of at least two polymers and are provided on a fiber cross-section in a direction perpendicular to the fiber axis. The islands-in-sea fiber is a raw yarn for a combined filament yarn, which can be used to produce a cloth having good tension and drape and an excellent color-developing property. An islands-in-sea fiber in which at least two types of island components having different diameters are arranged on the same fiber cross section, the islands-in-sea fiber characterized in that at least one type of the island components have diameters of 10-1000 nm and have fluctuations in diameters of 1.0-20.0%. |

1. A sea-island composite fiber having a cross section containing a plurality of island components having different island diameters, at least one of the island components having island diameters of 10 to 1,000 nm with a diameter variation of 1.0 to 20.0%, differences in island diameter among the island components are 300 to 3,000 nm and a variation in a distance between centers of adjacent island domains with the same diameter being 1.0 to 20%. |
