Non-woven fabrics are connected by stringing and the methods of producing these non-woven fabrics

Abstract

The invention relates to a spun-bonded nonwoven fabric of excellent strength even at low base weight and excellent flexibility and tactile feel; the spun-bonded nonwoven fabric according to the invention is a spun-bonded nonwoven fabric of a core-shell synthetic fiber containing polypropylene resin as the main component, in which the spun-bonded nonwoven fabric has a bonded region and a non-bonded region, The ratio (Os / Oc) of the orientation parameter Os of the shell component of the core-shell composite fiber in the unbonded region to the orientation parameter Oc of the core component of the core-shell composite fiber in the unbonded region is between 0.10 and 0.90.
