PURPOSE:The titled fiber that comprises a polyethylene resin composition consisting of a plurality of polyethylene with specific density and different Q values in a specified proportion, thus giving soft-touch nonwoven fabrics, when mixed with other fibers and subjected to hot-melting. CONSTITUTION:The objective fiber is obtained using alone a polyethylene resin composition consisting of (A) 50-100wt% of a polyethylene with a density of 0.910-0.940g/cm<3>, a Q-value of less than 4.0, calculated as Q=Mw/Mn where Mw is weight-average molecular weight and Mn is number-average molecular weight, and of (B) 50-0wt% of another polyethylene with a density of 0.910- 0.930g/cm<3> and a Q-value of more than 7.0, or using the composition as a component for the conjugation so that the composition is exposed to at least a part of the fiber surface continuously. The other component for conjugation is preferably polypropylene. |
