Polymeric blends and polymeric mixtures that incorporate a blend of a first polyethylene and a second polyethylene are described. The first and second polyethylenes have a predetermined relationship for the density and the melt index of the individual polyethylenes. Also described are fibers (including bicomponent fibers) and nonwoven materials made from the fibers where the fibers are extruded using the polymeric blends, and/or the polymeric mixtures.
La présente invention concerne des assemblages polymères et des mélanges polymères qui comprennent un assemblage d'un premier polyéthylène et d'un second polyéthylène. Le premier et le second polyéthylènes présentent une relation prédéfinie concernant la densité et l'indice de fusion des polyéthylènes individuels. La présente invention concerne également des fibres (y compris des fibres à biocomposant) et des matières non-tissées produites à partir desdites fibres qui sont extrudées en utilisant les assemblages polymères et/ou les mélanges polymères.
