Embodiment 1
[0025] Warp the polyurethane yarn of 40D and the cationic modified polyester filament of 40D / 12f respectively, wherein the draft ratio of the polyurethane yarn is 180%, and then weave it on a warp knitting machine to obtain gray fabric of elastic fabric. The structural organization of the fabric is warp velvet weave, in which the polyurethane yarn is placed on the rear bar to weave the warp weave; the cationic modified polyester filament is placed on the front bar to weave the warp plain weave.
