To provide a three-dimensional knitted fabric laminate having cushioning properties free from bottom-attaching feeling after taking a seat, good fitting feeling and good resilient feeling when used as a cushioning material, in a three-dimensional knitted fabric used as a cushioning material for offices, bedding, bed pad, etc. and a cushioning material for automobiles, railway vehicles, aircraft, etc.
The three-dimensional knitted fabric laminate is obtained by laminating two or more layers of three-dimensional knitted fabrics each composed of a knitted fabric having two layers of surface and rear and a connecting layer composed of a monofilament connecting yarn for connecting two-layered knitted fabrics. The three-dimensional knitted fabric laminate is composed of (a) three-dimensional knitted fabrics in which compression ratios laid under 245N load by using a compression disk having 100 mm diameter are mutually different and has (b) ≥15 mm and ≤50 mm thickness, (c) ≥10% and ≤80% compression ratios laid under 245N load using a compression disk having 100 mm diameter and (d)≥5% and ≤40% hysteresis loss ratio in compressive recovery laid under 245N load by using a compression disk having 100 mm diameter.
