Abstract
This invention provides a thermal bonding conjugate fiber having excellent compression resistance and nonwoven fabric using the same. Particularly, the nonwoven fabric retains bulkiness obtained under a light load even under a heavy load and reduces a decrease in bulkiness from under a light load to under a heavy load. The thermal bonding conjugate fiber has an eccentric core-sheath structure in which a first component including a polyester resin constitutes a core and a second component including a polyolefin resin having a melting point at least 15° C. lower than that of the polyester resin constitutes a sheath, and a shrinkage ratio of the conjugate fiber after a heat treatment of 120° C. is at least 20%. The nonwoven fabric is obtained by blending the thermal bonding conjugate fiber at a blend ratio of 10 to 60 wt % with one or more types of different thermal bonding fibers.
