PURPOSE: To obtain a non-woven fabric of high strength and good bulkiness, further having flexible fabric hand and to obtain heat-fusible conjugated fibers giving the same. CONSTITUTION: In parallel or sheath-core type conjugated fibers which comprise a high-melting component of a polypropylene or a polyester and a low-melting component of a polyethylene where the polyethylene forms at least a part of the fiber surface continuously in the fiber-length direction, the polyethylene has 0-15 methyl branches/1000C, 0.950-0.965g/cm<3> density and less than 4.5 Q value (ratio of weight-average molecular weight (Mw)/number-average molecular weight (Mn)), and a nonwoven fabric which contains more than 20wt.% of the conjugated fibers heat-fused is produced. |
