PURPOSE: To dissolve deficiency of stretchability and obtain cellulose acetate woven or knit fabric-like nonwoven fabric by forming many thermally fused and pressed areas into a cellulose acetate nonwoven fabric web and forming cracks in the thermally fused and pressed area. CONSTITUTION: Partially isolated many thermally fused and pressed areas 1 are formed over whole face of a cellulose acetate nonwoven fabric web and cracks C are formed in >=80% thermally fused and pressed areas 1 by drawing, etc. Woven or knit fabric-like expanding and contracting action occurs by the cracks. |
