Abstract: A splint for orthopedics with a mid-layer material made from a stretchable woven fabric knitted with a double raschel warp knitting machine and impregnated with a water-curable resin; and top and bottom surface layers consisting of a non-woven fabric stretchable in both horizontal and vertical directions and a barrier layer against the water-curable resin. The stretchable woven fabric is knitted with a double raschel warp knitting machine, which comprises six symmetrically arranged warpers beams, wherein the outer beams hold coarse polyester yarns; the inner beams hold fine polyester yarns, and the central beams hold rubber threads. The barrier layer includes a paper material susceptible to tearing or a synthetic resin film susceptible to stretching while applying the splint. In another embodiment, as the top and bottom surface layers, a paper material susceptible to tearing or a synthetic resin film susceptible to stretching while applying the splint may be used.
