A bielastic warp-knit fabric with balanced behavior of the elastic forces in the longitudinal and transverse directions is obtained by guiding elasthane yarn as weft thread under the needle points in the tuck or laying position during the stitch-forming process, so that loops are formed during knocking-over.
