ABSTRACT:
A non-woven fabric having a high strength, a good bulkiness and a soft feeling, and hot-melt-adhesive conjugate fibers affording the non-woven fabric are provided, the above hot-melt-adhesive conjugate fibers being composed of conjugate fibers, of side-by-side type or sheath-and-core type, composed of a high melting component of a polypropylene or a polyester and a low melting component of a polyethylene, the polyethylene continuously forming at least one portion of the fiber surface in the direction of the fibers; hot-melt-adhesive conjugate fibers characterized in that the polyethylene has 0 to 1.5 methyl branch/1000 C in the molecular chain, a density of 0.950 to 0.965 g/cm 3 and a Q value (weight average molecular weight (Mw)
umber average molecular weight (Mn)) of 4.5 or less, and the above hot-melt-adhered non-woven fabric being characterized by containing 20% by weight or more of the above hot-melt-adhesive conjugate fibers.
