PURPOSE:The titled heat fusible fibers, obtained by spinning a composition prepared by adding a specific amount of a petroleum resin to a polyolefin based resin alone or using the composition as one component of side-by-side type or sheath-core type conjugate fibers and suitable as facing materials in disposable diapers, etc. CONSTITUTION:Polyolefin based heat fusible fibers obtained by adding 1-20wt% petroleum resin, e.g. alicyclic petroleum resin consisting essentially of a 9C alkylbenzene, etc., to a polyolefin based resin, e.g. polyethylene, etc., and, as necessary, adding a stabilizer, colorant, etc., to give a composition, spinning the composition as one-component fibers, one component of a side-by-side type conjugate fibers in the form of applied two components or sheath-core type conjugate fibers having a high-melting component arranged on the core side and a low-melting component arranged on the sheath side, drawing and heat- treating the resultant fibers. The difference in melting point between the respective components of the above-mentioned conjugate fibers is preferably >=20 deg.C.
