| abstract |
The invention provides a nonwoven fabric of crimped conjugate fibers comprising (1) a first propylene-based polymer component and (2) a second propylene-based polymer component, and a laminate of the nonwoven fabric and other nonwoven fabrics or porous films, in which the melting point of the component (1) is higher by at least 20° C. than that of the component (2) a ratio of the two components in melt flow rate (component ( 2 )/component ( 1 )) is in the range of 0.8 to 1.2, and the component ratio expressed by (1)/(2) (by weight) is 50/50 to 5/95. The nonwoven fabric has an excellent bulkiness and softness, is excellent in terms of spinnability and fuzzing resistance, and can be spun by a conventional melt spinning. The laminate has further improved water impermeability and surface smoothness. The nonwoven fabric and the laminate using the same may both be used for disposable diapers or sanitary napkins. |
