PURPOSE: To provide a double-face circular knit which has improved molding adaptability and fiber surface modification property, is easy to process, is low in cost and made easily disposable by recycling.

CONSTITUTION: This double-face circular knit comprises two concentric lengths of knit web and an in-between spacer structure. Spacer threads are optionally textured coarse-filament multifilament yarns which are optionally in combination with monofilaments and are optionally textured. The distance between the two lengths of knit web is from 0.3 to 8 mm, the stitch density corresponds to a machine gage from E16 to E21 and the density of the spacer threads is between 150 to 250 threads per cm2. Preferably all the yarns of the double-face circular knit are made of the same polymer. Also described are the production and use of this double-face circular knit.
