PURPOSE:To obtain the subject nonwoven fabric resistant to hardening of feeling, having excellent tensile strength and suitable for operating gown, etc., by using a polypropylene having an isotactic pentad fraction falling within a specific range. CONSTITUTION:The objective nonwoven fabric is produced by using a polypropylene having an isotactic pentad fraction (abbreviated as I5) of 0.880-0.930 and an I5 difference between a boiling cyclohexane insoluble fraction and a boiling cyclohexane soluble fraction of >=0.050. The polypropylene is preferably a polypropylene mixture produced by mixing two or more kinds of polypropylenes having different I5 values of the resins and different I5 values between the boiling cyclohexane insoluble fraction and soluble fraction. |
