PURPOSE: To produce composite nonwoven fabric excellent tensile stretch, feeling and water absorptivity, and useful for gauze or the like by forming many cohesive points in web made of synthetic fiber filaments, by laminating regenerated fiber web on it and by entangling the laminate with high pressure water jets so as to be in a unified state. CONSTITUTION: The objective nonwoven fabric where synthetic fiber and regenerated one are joined together in an mutually entangled state is produced by the following steps: (1) forming synthetic fiber web using synthetic fiber filaments, followed by partially fusing the filaments in the web among them to impart many cohesive points to the web; (2) forming regenerated fiber web using regenerated fiber filaments and superimposing it on at least one surface of the synthetic fiber web; (3) entangling the plural superimposed sheets. of web with high pressure water jets so as to be in a unified state, wherein the total area of the cohesive points in the synthetic fiber web is <=15% based on the whole area, and the cohesive points are placed at an interval of >=5 cm in the longitudinal and transverse directions of the nonwoven fabric surface. |
