Abstract
A fabric is subjected to calender processing on one or both surfaces and includes a polyamide fiber as warp or/and woof having, after calender processing, a single filament fineness of 0.5 to 2.5 dtex and a total fiber fineness of 5 to 50 dtex, the single filament having a cross-sectional shape that is flat multifoliar with 6 to 10 lobe parts and has a flat ratio (W) (α/β) of 1.5 to 3.0, the fabric having a cover factor of 1200 to 2500.

A fabric subjected to calender processing on one or both surfaces, comprising a polyamide fiber used as warp or/and woof having, after calender processing of the fabric, a single filament fineness of 0.5 to 2.5 dtex and a total fiber fineness of 5 to 50 dtex, the single filament having a cross-sectional shape that is flat multifoliar with 6 to 10 lobe parts and has a flat ratio (W) (α/β) of 1.5 to 3.0, wherein a is a length of a line segment A, which is a longest line segment connecting any two apexes of convex portions of the flat multifoliar shape, and β is a length of a line segment B of a circumscribed quadrangle formed by lines parallel to the line segment A and are tangent lines containing outermost apexes (the angle between adjacent sides is 90°), the line segment B being other than the lines parallel to the line segment A, the fabric having a cover factor of 1200 to 2500.
