LAMINATED NONWOVEN FABRIC AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a nonwoven fabric exhibiting nonconventional surface shape and rich in bulkiness and softness. SOLUTION: A short fiber web having latent crimping ability and three- dimensionally crimped by actualizing latent crimping and a short fiber web which does not shrink at a heat treating temperature under relaxation for actualizing latent crimping are laminated to provide the objective laminated nonwoven fabric in which component fibers are mutually three-dimensionally entangled and integrated and having crepe on the nonwoven fabric surface on the side of the short fiber web which does not shrink.
