Abstract
PURPOSE: To produce a bulky nonwoven fabric excellent in pliability and suitable for a paper diaper, etc., by compounding two kinds of polypropylene-based polymers in a side-by-side type in a core component and using a polyethylene- based polymer having a specific melting point as a sheath component and including the resultant conjugated fiber. CONSTITUTION: A polypropylene-based polymer 1a having >=6 value of Q of the weight-average molecular weight/the number-average molecular weight and a polypropylene-based polymer 1b having <=5 value of Q are compounded in (1:2) to (2:1) compounding ratio into a side-by-side type to form a core component 1, which is covered with a polyethylene-based polymer 1b having a lower melting point than that of the component having the lower melting point of the core component by >=20 deg.C in an amount of 25-55 wt.% based on the total amount of the core and sheath as a sheath component 2 to afford a heat bonding conjugated fiber. The resultant heat bonding conjugated fiber in an amount of >=30 wt.% is then included in other fibers (e.g. rayon or cotton) to produce the objective nonwoven fabric.
