Abstract
An object of the invention is to provide thermo-fusible conjugated fibers capable of suppressing damage to the fibers upon processing the fibers into a nonwoven fabric web. The thermo-fusible conjugated fibers of the invention contain a first component containing a polyester-based resin and a second component containing a polyolefin-based resin, in which a melting point of the second component is 10° C. or more lower than a melting point of the first component, and a work load at break obtained by a tensile test is 1.6 cN·cm/dtex or more. The damage to the fibers is suppressed by the thermo-fusible conjugated fibers of the invention, and therefore the nonwoven fabric with higher quality can be obtained with higher productivity than ever before.
