The present invention provides a splittable multicomponent fiber containing at least two polymer components arranged in distinct non-occlusive segments across the cross-section of the fiber, wherein the segments are continuous along the length of the fiber, and wherein at least one of the polymer components comprises about 10 percent to about 95 percent by weight of filler material. The invention also provides split fibers, and fabrics containing the split fibers produced from the splittable multicomponent fiber, and laminates containing the split fiber fabric. Additionally provided is a process for producing the split fibers and fabrics. La présente invention se rapporte à une fibre mulitcomposée clivable contenant au moins deux composants polymères agencés dans des segments non occlusifs distincts à travers la section transversale de ladite fibre, lesdits segments étant continus suivant la longueur de la fibre. L'un au moins des composants polymères comporte environ 10 % à environ 95 % en poids de matière de remplissage. L'invention se rapporte également à des fibres clivées, et à des étoffes contenant ces fibres clivées produites à partir de ladite fibre multicomposée clivable, ainsi qu'à des stratifiés contenant ladite étoffe à fibres clivées. L'invention se rapporte en outre à un procédé permettant de produire ces fibres clivées et ces étoffes.
