Abstract: PURPOSE:To obtain the subject nonwoven fabric, having specific extension recovery ratio, compressive bending resistance and apparent density value and excellent in stretchability, flexibility, etc., by using polypropylene-based crimped fiber and heat bonding fiber and providing dot fused areas and nondot fused areas. CONSTITUTION:(A) Polypropylene-based crimped fiber composed of two components having different melting points is blended with (B) heat bonding fiber composed of two components of a component (e.g. polyethylene) having a lower melting point than that of the low-melting component in the component (A) and a component (e.g. polypropylene) having a higher melting point than that at 100:(5-400) ratio by pts.wt. and >=6% of the whole area of the nonwoven fabric is dot fused by melting and solidifying. The others are formed into a nondot fused area to crimp the blended fiber with heat. Thereby, the objective nonwoven fabric having >=25% extension recovery ratio at 30% extension for both the longitudinal and transverse directions, <=80g compressive bending resistance and <=0.1g/cm<3> apparent density is obtained.
