Fibers suitable for the production of nonwoven fabrics having improved strength and softness characteristics. |
摘要 |
<p>Disclosed is a fiber for nonwoven fabrics comprising an olefin polymer material containing (by weight): 1) from 50 to 80 parts of a propylene homopolymer having an isotactic index greater than 90, or a random copolymer of propylene with ethylene and/or a C4-C8 alpha -olefin; and 2) from 20 to 50 parts of a heterophasic polymer comprising a copolymer containing from 40 to 70% of ethylene, and having an intrinsic viscosity lower than or equal to 1.5 dl/g, or said copolymer containing less than 40% of ethylene and having an intrinsic viscosity lower than or equal to 2.3 dl/g; said fiber being obtained by spinning the above olefin polymer material and then drawing it out with a draw-ratio equal to or lower than 1.8.</p> |
