Inelastic, conformable sports tape
An athletic tape product for securing or supporting a human or animal body part is provided that includes an elongate, pliable, woven substrate that is stretched in the long direction and impregnated with a water-dispersible polymer, the stretched, impregnated woven substrate further including a coating selected from the group consisting of a cohesive material or an adhesive material. In certain embodiments, the pliable woven substrate is cotton.
1. An athletic tape product for securing or supporting a human or animal body part, the product comprising:
an elongate, pliable, substrate having a first major surface and a second major surface, the substrate being formed of a woven material that is stretchable in a longitudinal direction between a relaxed state and a stretched state, wherein a longitudinal length of the substrate in the stretched state is greater than the longitudinal length of the substrate in the relaxed state;
a polymer material applied to the substrate, the polymer material affixing the substrate in the stretched state; and
a coating material disposed on one or both of the first major surface and the second major surface, the coating material selected from the group consisting of a cohesive material and an adhesive material.
2. The athletic tape product of claim 1 , wherein the substrate is a woven material comprising longitudinal fibers extending in the longitudinal direction and transverse fibers extending transversely with respect to the longitudinal direction.
3. The athletic tape product of claim 2 , wherein the longitudinal fibers, transverse fibers, or both comprise a material selected from the group consisting of cotton, polyolefin, polyester, and a cotton/synthetic polymer blend.
4. The athletic tape product of claim 2 , wherein the longitudinal fibers, transverse fibers, or both have a linear mass density of from about 50 deniers to about 500 deniers.
5. The athletic tape product of claim 2 , wherein the longitudinal fibers are spaced along a transverse axis at a density of from about 20 to about 100 fibers per inch when the substrate is in the relaxed state.
6. The athletic tape product of claim 2 , wherein the transverse fibers are spaced along a longitudinal axis at a density of from about 15 to about 75 fibers per inch when the substrate is in the relaxed state.
7. The athletic tape product of claim 1 , wherein the coating material is disposed on the first major surface at a coating density of from about 40 g/m 2 to about 150 g/m 2 .
8. The athletic tape product of claim 1 , wherein the coating material is an adhesive material.
9. The athletic tape product of claim 8 , wherein the adhesive material comprises a material selected from the group consisting of a styrene-butadiene rubber (SBR) adhesive and an acrylate adhesive.
10. The athletic tape product of claim 1 , wherein the coating material is a cohesive material.
11. The athletic tape product of claim 10 , wherein the cohesive material comprises a material selected from the group consisting of polychloroprene, polyester polyurethane, and polycaprolactone polyurethane.
12. The athletic tape product of claim 1 , wherein the polymer material is a water-dispersible polymer.
13. The athletic tape product of claim 12 , wherein the substrate is impregnated with the water-dispersible polymer.
14. The athletic tape product of claim 12 , wherein the substrate is coated with the water-dispersible polymer.
15. The athletic tape product of claim 12 , wherein the water-dispersible polymer is disposed on the first and second major surfaces at a coating density of from about 10 g/m 2 to about 40 g/m 2 , on a dried weight basis.
16. The athletic tape product of claim 12 , wherein the water-dispersible polymer is ethylene vinyl acetate.
17. The athletic tape product of claim 1 , wherein the longitudinal length of the substrate in the stretched state is at least 0.5% greater than the longitudinal length of the substrate in the relaxed state.
18. The athletic tape product of claim 1 , wherein the substrate is impregnated with the coating material.
