Abstract
The cap ply reinforcement strip is a ready-to-use plain woven fabric and is composed of hybrid cord warps (3) and texturized weft yarns (2). The cap ply reinforcement strip for pneumatic tires (1) eliminates calendering and strip preparation steps by eliminating the need for rubber coating and decreases the rolling resistance of the tire and the fuel consumption.
Claims20
A cap ply reinforcement strip for pneumatic tires, comprising:
- a plurality of texturized weft yarns provided parallel to each other with intervals and are used as support members enabling a base structure to be kept together, wherein the plurality of texturized weft yarns are prepared from at least one material selected from the group consisting of nylon 6.6, nylon 6, and polyethylene terephthalate (PET);
- and
- a plurality of hybrid cord warps comprising:
- at least one first yarn with a first modulus and at least one second yarn with a second modulus, wherein the first modulus is higher than the second modulus;
- wherein a plain woven structure is formed by passing the hybrid cord warps which are parallel to each other orthogonally through the texturized well yarns, and by a plurality of spacings between the hybrid cord warps being minimized and being completely filled with a tacky material (tacky Resorcinol Formaldehyde Latex);
- wherein the texturized weft yarns comprise Resorcinol Formaldehyde Latex at a plurality of contact points formed with the hybrid cord warps;
- wherein the cap ply reinforcement strip comprises Resorcinol Formaldehyde Latex (RFL) on an outer surface of the cap ply reinforcement strip, wherein a total amount of the Resorcinol Formaldehyde Latex (RFL) dip content (Dip Pick Up, DPU %) in the cap ply reinforcement strip ranges from 26% to 50%;
- wherein the cap ply reinforcement strip is rubber free and there is no rubber coating on the cap ply reinforcement strip.
