Title:
改善された不織布および繊維
Document Type and Number:
Japanese Patent JP2007535624
Kind Code:
A
Abstract:
The present invention relates to nonwoven webs or fabrics. In particular, the present invention relates to nonwoven webs having superior abrasion resistance and excellent softness characteristics. The nonwoven materials comprise fibers made from of a polymer blend of isotactic polypropylene, reactor grade propylene based elastomers or plastomers, and optionally, a homoge-neously branched ethylene/alpha olefin plastomer or elastomer. The isotactic polypropylene can be homopolymer polypropylene, and random copolymers of propylene and one or more alpha-olefins. The reactor grade propylene based elastomers or plastomers plastomer have a molecular weight distribution of less than about 3.5, and a heat of fusion less than about 90 joules/gm. In particular, the reactor grade propylene based elastomers or plastomers contains from about 3 to about 15 percent by weight of units derived from an ethylene, and a melt flow rate of from about 2 to about 200 grams/10 minutes. The present invention also relates to cold drawn textured fibers comprising of a polymer blend of isotactic polypropylene and reactor grade propylene based elastomers or plastomers.
