Abstract
The present invention provides a warp knitted fabric containing a latent crimp fiber but no elastic fiber, and showing a stretchability of 60% or more in both the warp and weft directions, and a residual strain at 60% elongation recovery of 15% or less in both the warp and weft directions. The warp knitted fabric of the present invention shows little lowering of the stretchable functions during dyeing at high temperature, repeated washing, repeated stretching, or the like treatment, and is excellent in elongation recovery due to the high stretchability, surface smoothness and shape retention.
