Abstract
To provide thermoadhesive conjugate fibers, nonwoven fabrics and cellulosic fiber blended nonwoven fabrics employing them, and wipers and absorbers employing the fabrics, thermoadhesive conjugate fibers comprise a thermoplastic resin (I) containing a modified polyolefin with at least one type of reactive functional group as a first component and having a second component composed of a thermoplastic resin (II) with a higher melting point than the thermoplastic resin (I) of the first component combined in a conjugate therewith, the first component being formed continuously along the length of at least a portion of the fiber surface, wherein the fiber surfaces are coated with a fiber treating agent containing a multifunctional compound capable of reacting with the reactive functional group of the modified polyolefin.
