Abstract
Disclosed herein is a polyolefin splittable conjugate fiber comprising at least two components of polyolefin resins (including polystyrene resins) and having a cross sectional structure with each of the components arranged alternately, wherein at least one of the component resins contains 1-30% by weight of an ethylene-vinyl alcohol copolymer whose saponification degree is 95% or more. Using the splittable conjugate fiber of the invention, a fiber structure having a fine and even surface can be provided.
