    Abstract: Composite filament having an elastic crimping property, comprised of at least two components disposed in an eccentric sheath-core relation along the longitudinal axis of the filament, in which one component is composed of a polyester consisting mainly of polyethylene terephthalate and another component or components comprise highly shrinkable polyamide having a shrinking percentage of 15-80 percent and the percent by weight of the core or cores in the filament is 5-50. It is preferable that the core component is composed of the polyester and the sheath component is composed of the polyamide. Furthermore, the eccentricity of the sheath-core relation is preferably at least 5. The core component may be constituted with a plurality number of cores.
