Abstract:
PROBLEM TO BE SOLVED: To obtain at a low cost a nonwoven fabric which well fits to the body of a wearer as a raw material for clothes and has a good skin touch, a good wearing touch and excellent elasticity.
SOLUTION: This elastic nonwoven fabric is obtained by tensively arranging highly many warps 1 having elongation strains therein on a frame 2 to form a warp-arranged product 3, adhering a water-soluble sheet S to the arranged surface of the obtained warp-arranged product 3, sewing the warp-arranged product 3 and the water-soluble sheet S with the upper thread and the lower thread of a sewing machine in two bias directions at a prescribed needling movement pitch P, detaching the obtained warp-arranged and sewed sheet 6 from the frame 2, washing the detached sheet 6 with water to dissolve off the water-soluble sheet S and simultaneously release the inner elongation strains from the warps 1, respectively, and then drying left warp-arranged product to shrink and simultaneously curl the many warps 1 for each bias sewed distance, thereby imparting the elasticity to the nonwoven fabric. The warps 1 may be strings, braids or cloth tapes.
