Abstract: Multicomponent thermoplastic continuous filaments are provided, including hollow core multicomponent filaments. The filaments are at least partially splittable into smaller filaments in the absence of mechanical treatment or application of high pressure water jets. The surface energy of the components can be controlled to control separation of the multi-component filaments. Sub-denier and micro-denier filaments of low orientation can be produced from relatively high molecular weight polymers to produce nonwovens of surprising strength, barrier, and cover.
