Abstract:
A spunbond nonwoven fabric, including a composition including a propylene homopolymer having a melting point of 140° C. or higher, a polyethylene, and at least one polymer selected from the group consisting of a polymer shown in (I) and a polymer shown in (II), in which the total content of the polymer shown in (I) and the polymer shown in (II) is in a range of from 5% by mass to 30% by mass with respect to the total amount of the composition. The polymer shown in (I) is a random copolymer of propylene and an α-olefin having a specific number of carbon atoms, and the polymer shown in (II) is a propylene homopolymer having a melting point less than 120° C. and exhibiting specific physical properties.

Claim (Index 1):
A spunbond nonwoven fabric, comprising a composition comprising a propylene homopolymer having a melting point of 140\u00b0 C. or higher, a polyethylene, and at least one polymer selected from the group consisting of a polymer shown in the following (I) and a polymer shown in the following (II),\n wherein a total content of the polymer shown in the following (I) and the polymer shown in the following (II) in the composition is in a range of from 5% by mass to 30% by mass with respect to a total amount of the composition: \n (I) a random copolymer of propylene and at least one selected from ethylene and a C4-C20 \u03b1-olefin, and \n (II) a propylene homopolymer having a melting point less than 120\u00b0 C. and satisfying the following (a) to (f):\n [ mmmm ]=20 mol % to 60 mol %\u2003\u2003(a) \n [ rrrr ]/(1 \u2212[mmmm ])\u22640.1\u2003\u2003(b) \n [ rmrm ]>2.5 mol %\u2003\u2003(c) \n [ mm]\u00d7[rr]/[mr] 2 \u22642.0\u2003\u2003(d) \n weight-average molecular weight (Mw)=10,000 to 200,000\u2003\u2003(e) \n molecular weight distribution (Mw/Mn)<4,\u2003\u2003(f) \n \n wherein, in (a) to (d), [mmmm] represents a meso pentad fraction, [rrrr] represents a racemic pentad fraction, [rmrm] represents a racemic meso racemic meso pentad fraction, and [mm], [rr] and [mr] each represent a triad fraction.
