<P>PROBLEM TO BE SOLVED: To provide a polypropylene nonwoven fabric molding having excellent workability at low temperatures at the time of manufacturing of a nonwoven fabric and also having excellent fusing characteristics at the time of processing of final products. Ž<P>SOLUTION: The nonwoven fabric is formed of a fiber containing a propylene-α-olefin random copolymer at least as one composition. The propylene-α-olefin random copolymer is polymerized by a metallocene catalyst, in which an MFR is 10-100g/10 min., a Q value is 2-4, Tm is 110-140°C, a temperature (T<SB>10</SB>) is 50°C or higher when a soluble content of an o-dichlorobenzene is 10 wt.% or higher, an α-olefin content (α) is 1-18 mol%, and a tensional modulus of elasticity (YM) and the α-olefin content (α) satisfy the expression (a): YM≤-52.3×α+1100. The polypropylene nonwoven fabric molding is formed by fusing the nonwoven fabric and the adherend by ultrasonic fusing. Ž<P>COPYRIGHT: (C)2006,JPO&NCIPI Ž |
