Abstract
It is to provide a three-dimensional warp-knitted fabric in which breathability and cushioning property especially are well suited for a motor vehicle seat in a manner that a feeling of stickiness and steaminess when sweating is eliminated. The three-dimensional warp-knitted fabric comprising front and back ground structures, one of which has a smaller number of loops (1), the other ground structure having a larger number of loops (2); and connecting yarns for connecting these two ground structures (4). One of the ground structures (1) and the other ground structure (2) being knitted with different number of needles, and the number of loops of the ground structure having the smaller number of loops (1) being 30 to 75% that of the other ground structure having the larger number of loops (2). Moreover, the per-area weight of the ground structure having the small number of loops is 60 to 150% of the ground structure having the larger number of loops.
