Claims
- 1. A knitted substrate suitable for use in a resin-coated, water-hardenable orthopedic splinting bandage, said substrate comprises a warp knitted fabric having a chain stitch in the warp direction thereof and comprises inelastic fibers of low modulus of elasticity selected from the group consisting of polypropylene and polyester fibers, and elastic fibers, said elastic fibers being knitted in with or laid into said chain stitch and said inelastic fibers comprising filaments having a modulus of less than 3.times.10.sup.6 psi.
- 2. A substrate according to claim 1 in which the substrate has an extension in the warp direction of from 15% to 80% and an extension in the weft direction of from 20% to 100%.
- 3. A substrate according to claim 1 in which the substrate has a weight per unit area of from 50 to 500 gm.sup.-2 and from 200 to 300 openings per square inch.
- 4. A substrate according to claim 1 in which the elastic fibers are natural rubber fibers or polyurethane fibers.
- 5. A knitted substrate suitable for use in a resin-coated, water-hardenable orthopedic splinting bandage, said substrate comprising a warp knitted fabric having a chain stitch in the warp direction thereof and comprises inelastic fibers of low modulus of elasticity selected from the group consisting of polypropylene and polyester fibers, and elastic fibers, said elastic fibers being knitted in with or laid into said chain stitch and said inelastic fibers comprising filaments having a modulus of elasticity of less than 3.times.10.sup.6 psi, and in which the inelastic fibers have a modulus of elasticity of less than 2.times.10.sup.4 psi.
- 6. A substrate according to claim 5 in which the inelastic fibers of low modulus of elasticity are polypropylene fibers.
- 7. A substrate according to claim 5 in which the inelastic fibers of low modulus of elasticity are polyethylene terephthalate fibers.
- 8. A conformable water hardenable orthopedic splinting bandage comprising a knitted substrate coated with a curable resin wherein said substrate is a warp knitted fabric having a chain stitch in the warp direction thereof and comprises inelastic fibers of low modulus of elasticity selected from the group consisting of polypropylene and polyester fibers, and elastic fibers, said elastic fibers being incorporated in said chain stitch, and wherein said inelastic fibers comprise filaments having a modulus of elasticity of less than 3.times.10.sup.6 psi.
- 9. A bandage according to claim 8 in which the resin is a water curable isocyanate terminated prepolymer system.
- 10. A bandage according to claim 8 in which the substrate when coated with resin has an extension in the warp direction of from 15% to 80% and an extension in the weft direction of from 20% to 100%.
- 11. A bandage according to claim 8 in which the uncoated substrate has a weight per unit area of from 50 to 500 gm.sup.-2 and the weight of the resin is 40 to 60% of the total weight of the bandage.
- 12. A bandage according to claim 8 in which the elastic fibers are natural rubber fibers or polyurethane fibers.
- 13. A conformable water hardenable orthopedic splinting bandage comprising a knitted substrate coated with a curable resin wherein said substrate is a warp knitted fabric having a chain stitch in the warp direction thereof and comprises inelastic fibers of low modulus of elasticity selected from the group consisting of polypropylene and polyester fibers, and elastic fibers, said elastic fibers being incorporated in said chain stitch, and wherein the inelastic fibers have a modulus of elasticity of less than 2.times.10.sup.4 psi.
- 14. A bandage according to claim 13 in which the inelastic fibers of low modulus of elasticity are polypropylene fibers.
- 15. A bandage according to claim 13 in which the inelastic fibers of low modulus of elasticity are polyethylene terephthalate fibers.
- 16. A bandage according to claim 8 in which the weight of the resin on the substrate is from 150 to 500 gm.sup.-2.
