Polypropylene Nonwoven Fabric and Use Thereof |
摘要 |
A polypropylene based nonwoven fabric is excellent in surface appearance and stretch properties and exhibits a small residual strain and excellent adhesiveness to polyolefins. The nonwoven fabric is obtained by forming a polypropylene resin composition comprising 1 to 40 weight parts of (i) an isotactic polypropylene, and 60 to 99 weight parts of (ii) a propylene/ethylene/alpha-olefin copolymer obtained by copolymerizing 45 to 89 mole % of propylene, 10 to 25 mole % of ethylene and the balance of alpha-olefin having 4 to 20 carbon atoms (with the proviso that the copolymerized amount of the alpha-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%. The nonwoven fabric can be effectively used as sanitary materials or the like by virtue of its characteristics including stretch properties. |
