Beschreibung
Zusammenfassung:	Provided is a dyeable polyolefin fiber comprising a sea-island structure in which a polyolefin (A) is the sea component and a copolyester (B) obtained by copolymerizing cyclohexanedicarboxylic acid is the island component, the polyolefin fiber characterized in that the dispersion diameter of the island component in a lateral cross section of the fiber is 30 to 1000 nm. Provided is a dyeable polyolefin fiber in which bright, deep coloring is imparted to the lightweight polyolefin fiber, oxidative decomposition during tumbler drying and yellowing during long-term storage are minimized, and the polyolefin fiber can be suitably used as a fibrous structure.
