Nonwoven fabrics made of an aliphatic polyester having a melt viscosity of 5.0x102-2x104 poises at a temperature of 190 DEG C. at a shear rate of 100 sec-1 and a melting point of 70 DEG -190 DEG C. The nonwoven fabric has biodegradability when it is buried in the ground and it is also excellent in tensile strength and tear propagation strength. Thus, the nonwoven fabric of the present invention is useful for sanitary materials, medical materials, packaging materials, agricultural covering materials, filters, oil absorption materials, materials for a daily life, padding cloth materials for clothes, cell separators, drain sheets for constructions and the like. |
