An improved, nonwoven fabric is constructed to have superior cloth-like characteristics including superior tear resistance, liquid absorbency, resistance to linting, resistance to separation of the fabric areas, flexibility, and softness. Said nonwoven fabric is comprised of at least one intermediate area of absorbent fibers sandwiched between a first outer area of reinforcing fibers and a second outer area containing of melt fibers. The areas of the nonwoven fabric of the present invention are bonded together first by needling and then by a heat treatment that melts at least some of the melt fibers.
