An object of the present invention is to provide a new multilayered composite fiber using polyacetal, which is derived mainly from methanol, which is a raw material that does not depend on petroleum, and furthermore, a nonwoven fabric bonded by thermal bonding. According to the present invention, a multi-layered composite fiber containing a resin having a polylactic acid as a main component and a resin having a polyacetal as a main component and forming a continuous layer in the fiber axial direction and a nonwoven fabric obtained by thermally bonding the fibers are Can provide. |
