<p>A liquid impermeable sheet comprising a melt blown non woven fabric and an absorbent article using liquid impermeable sheet are provided. The melt blown non woven fabric comprises ultra fine fibers of thermoplastic polymer spun by a melt blowing method, and the fiber diameter is 10 mum or less. The melt blown non woven fabric satisfies the following Formulas (A): 2<=W/D2<=200 and (B): 0.05<=d<=0.2 where W is basis weight (g/m2), D is fiber diameter (mutm) and d is apparent density of the non woven fabric (g/cc), and thus, the fabric is excellent in feeling, flexibility and air permeability, while it keeps its liquid impermeability.</p> |
