PROBLEM TO BE SOLVED: To provide a polyamide-based woven fabric maintaining dry touch feeling with no stuffy or sticky feeling. SOLUTION: In this polyamide-based woven fabric provided, the polyamide fiber therein has numerous micropores on its surface, being obtained by alkali reduction of conjugate fiber made from a blend of a thermoplastic polyamide(A) and a readily alkali-soluble polyester(B) in the mass ratio of (95:5) to (70:30) to elute the readily alkali-soluble polyester(B) into the alkaline solution. The polyamide-based woven fabric has a cover factor CF of≥1,500, wherein the cover factor CF is represented by the formula:CF=X×D1<SP>1/2</SP>+Y×D2<SP>1/2</SP>( wherein, X is warp density(count/2.54cm); Y is weft density(count/2.54cm); D1 is the apparent fineness of warp(dtex); and D2 is the apparent fineness of weft(dtex) ). In this fabric, it is preferable that the polyamide fiber has hollows in its core part. COPYRIGHT: (C)2006,JPO&NCIPI |
