A laminated nonwoven fabric having excellent bulkiness, softness and strength without cleavage of plys and fluff of fibers on the surface thereof which comprises a web mainly composed of a fiber having a high melting point or being hardly softened or molten (laminate ply A), and one or more webs mainly composed of a thermoplastic fiber which soften or melt more easily than the fiber of the laminate ply A (laminate ply B), said ply B being integrally bound to said ply A by steric entanglement of both fibers composing the plys A and B as well as partial softening or melting of the fibers composing the ply B. The laminated nonwoven fabric is produced by subjecting a laminated web made of different kinds of fibers to a fluid injection entangling treatment and then a dry heat treatment.
A laminated nonwoven fabric which comprises a web mainly composed of a fiber having a high melting point or being hardly softened or molten designated as laminate ply A, and at least one web mainly composed of a thermoplastic fiber being soften or molten more easily than the fiber of the laminate ply A and provided on at least one surface of the laminate ply A designated as laminate ply B, said ply B being integrally bound to said ply A by steric entanglement of both fibers composing the plys A and B as well as partial softening or melting of the fibers composing the ply B.
A process for producing a laminated nonwoven fabric which comprises the steps of
