Abstract:
1. A three-dimensional uneven knitted fabric comprising a double Raschel warp knit fabric having front and back ground knitted structures and an interconnection yarn knitted with the structures that unites the front and back ground structures together and forms a part between them having voids therein, at least one of the front and back ground structures having an uneven surface pattern in section of projections and depressions, wherein ground yarns of the at least one ground structure are traversed by a predetermined traverse width ranging from 3 to 7 stitches along the width direction of knitting so that the projections each have a curved shape having a distinct curvature in section, and the ground yarns of the at least one ground structure are cast off at a predetermined interval corresponding to the predetermined traverse width of the ground yarns so that the depressions each have an opening, wherein (i) tensile forces toward centers of the projections are provided in portions of the at least one ground structure where the plurality of ground yarns overlap with each other, and (ii) the around yarns are cast off at the predetermined interval so that counter forces canceling the tensile forces do not occur.
