摘要：A polypropylene based nonwoven fabric is excellent in surface appearance andstretch properties and exhibits a small residual strain and excellent adhesiveness topolyolefins. The nonwoven fabric is obtained by forming a polypropylene resin
composition comprising 1 to 40 weight parts of (i) an isotactic polypropylene, and 60 to99 weight parts of (ii) a propylene/ethylene/α-olefin copolymer obtained bycopolymerizing 45 to mole % of propylene, 10 to 25 mole % of ethylene and thebalance of α-olefin having 4 to 20 carbon atoms (with the proviso that the copolymerizedamount of the α-olefin having 4 to 20 carbon atoms does not exceed 30 mole %),characterized by a small residual strain after stretching at a stretch ratio of 150%. Thenonwoven fabric can be effectively used as sanitary materials or the like by virtue of itscharacteristics including stretch properties.
