Abstract
A non-woven fabric of hot-melt-adhesive composite fibers having a specified small weight per unit area and soft feeling is provided which fibers are obtained by forming a fiber aggregate consisting of hot-melt-adhesive composite fibers of a specified fineness, alone, composed of as a first component, a polyethylene resin composition (C) consisting of (A) a straight chain, low density polyethylene and (B) another kind of polyethylene, in a specified proportion, and having a specified density and a specified ratio of its melt indexes after and before spinning, and as a second component, a fiber-formable polymer having a m.p. higher than those of either of the polyethylenes constituting the first component, the first component constituting at least a part of the fiber surface of the composite fibers continuously in the longitudinal direction thereof, or a fiber aggregate of a specified average fineness which is mixed fibers of the composite fibers with other fibers of a specified fineness; and subjecting either one of the fiber aggregates to heat treatment at a specified temperature.
