Title:
THERMAL BONDING CONJUGATE FIBER AND NONWOVEN FABRIC USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/025062
Kind Code:
A3
Abstract:
The present invention provides a thermal bonding conjugate fiber with excellent compression resistance and nonwoven fabric using the same. More specifically, the present invention provides a thermal bonding conjugate fiber and nonwoven fabric using the same, in which the bulkiness of the nonwoven fabric under a light load is retained well even under a heavy load, and the rate of decrease in bulkiness between under a light load and under a heavy load can be reduced. The thermal bonding conjugate fiber with thermal shrinkage properties has an eccentric core-sheath structure in which a first component comprising a polyester resin constitutes a core and a second component comprising a polyolefin resin having a melting point at least 15°C lower than a melting point of the polyester resin constitutes a sheath, and a shrinkage ratio after a heat treatment of 120°C is at least 20% when calculated by a predetermined measurement method. The nonwoven fabric is obtained by blending the thermal bonding conjugate fiber with one or more types of a different thermal bonding fiber, and the thermal bonding conjugate fiber is contained therein at a blend ratio of 10 to 60 wt%.
