Abstract
A biconstituent fiber having good spinnability, a binder fiber made thereof, and a nonwoven fabric produced therefrom and which has high tensile strength and comfortable soft touch are provided. The biconstituent fiber is composed of linear low-density polyethylene and crystalline polypropylene and may be hollow or flat in cross section. A binder fiber may be produced from a bicomponent structure in which the biconstituent fiber serves as a sheath component and polyethylene terephthalate as a core component.
