Abstract
A bicomponent elastic fiber that includes a core formed of an elastic fiber and having a sheath formed of a non-elastic material surrounding the core. The sheath has at least one cut therein extending at an angle to the length of the fiber to expose and release the elasticity of the core elastic fiber. This provides elasticity to the bicomponent elastic fiber.
