Abstract
Shown are thermo-fusible conjugate fibers having a high degree of crystallinity, while a degree of orientation is suppressed, and a bulky and soft nonwoven fabric using the same. The thermo-fusible conjugate fibers have, as a first component, a polyester-based resin, and as a second component, an olefin-based resin having a melting point lower than a melting point of the first component, in which the degree of orientation in the polyester-based resin is 6.0 or less, and the degree of crystallinity therein is 20% or more. The conjugate fibers are preferably sheath-core conjugate fibers in which the first component is a core component and the second component is a sheath component.
