Nonwoven fabric and process for producing thereof.

摘要

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.
