Abstract: Provided is a three-dimensional elastic circular knitted fabric combining light weight, heat retention, stretchability, and press shrinkage resistance. This three-dimensional elastic circular knitted fabric is obtained by connecting two front/back ground structures with a connecting yarn of only a tuck structure, wherein the three-dimensional elastic circular knitted fabric is characterized in that: the two front/back ground structures is solely constituted by non-elastic fiber; the connecting yarn is solely constituted by elastic fiber; the elastic fiber is interwoven at 2-15 courses/1 repeat; the loop density of the knitted fabric is 40-130 courses/inch, and 35-80 wells/inch; the filling rate is 5.0-25.0%; the thermal retention rate is 20.0% or higher; and the rate of elongation at a constant 22.1-N load is 50-200% in the warp direction and 150-300% in the weft direction.
