Abstract
To provide a spun-bonded nonwoven fabric having excellent strength even at a low basis weight and excellent flexibility and touch feeling, the spun-bonded nonwoven fabric of the present invention is a spun-bonded nonwoven fabric made of a core-sheath composite fiber containing a polypropylene-based resin as a main component, in which the spun-bonded nonwoven fabric has a bonding area and a non-bonding area, and a ratio (Os/Oc) of an orientation parameter Os of a sheath component of the core-sheath composite fiber in the non-bonding area to an orientation parameter Oc of a core component of the core-sheath composite fiber in the non-bonding area is 0.10 to 0.90.
Claims5
A spun-bonded nonwoven fabric comprising a core-sheath composite fiber including a polypropylene-based resin as a main component,
- wherein the spun-bonded nonwoven fabric has a bonding area and a non-bonding area, and
- a ratio (Os/Oc) of an orientation parameter Os of a sheath component of the core-sheath composite fiber in the non-bonding area to an orientation parameter Oc of a core component of the core-sheath composite fiber in the non-bonding area is 0.10 to 0.90.
