Definitions

  • the present invention relates to a hybrid cord structure used in tire production which is comprised of polyamide 6.6 (NY 6.6) and basalt fiber, and environmental friendly and has high performance.
  • Cord fabric used as reinforcing material in tire is comprised by adjoining thousands of warp yarns parallel to each other and weft yarns loose woven vertical to the warp yarns.
  • the weft yarns are generally not load bearing members; they are the yarns which only hold the warp yarns together.
  • the industrial yarns such as polyethylene terephthalate (PET), polyamide 6.6 /NY66), polyamide 6 (NY6), Rayon (RY), Aramide (Ar) and polyethylene naphthalate (PEN) which have high tenacity are the most commonly used materials that are used as rubber reinforcement member.
  • PET polyethylene terephthalate
  • NY6 polyamide 6
  • RY Rayon
  • Ar Aramide
  • PEN polyethylene naphthalate
  • the use of polyethylene terephthalate (PET) as reinforcement material in tire, hose, conveyor belt and belt applications has recently increased. The reason for this is that the deformation decreases significantly by means of the composite structure rubber the PET having HMLS (high modulus low shrinkage) with high strength and low elongation forms with the rubber. Therefore materials with more performance can be produced.
  • Rayon (RY) is a fiber which has very high dimensional stability but low resistance, moisture sensitivity and low strength.
  • Polyamide has higher resistance and resistance than the rayon whereas its dimensional stability is lower.
  • PEN fiber which is another PET, has higher dimensional stability, resistance and strength than PET.
  • Relatively new fibers such as carbon fiber, PBO, polyketone amongst the fibers with high performance like PEN are used as tire reinforcement material
  • the use of the said fibers cannot be generalized in tire because of their high cost.
  • the hybrid cords formed by combining fibers with different features become more developed products than the fibers forming themselves.
  • the twists of the hybrid cords having different twisting levels are realized in ring twist machines. Each fiber is produced by being twisted separately in ring twist machines, and then hybrid cord is formed by twisting the fibers having different features produced in different twisting levels in the ring twisting machines by being twisted together.
  • Nylon and Aramide are the materials that are mainly used in cap ply strip.
  • the objective of the present invention is to provide a high performance, new generation hybrid cord structure to be used in cap ply strip in pneumatic strips tires.
  • Figure 1 is the graphic of the force-elongation curves of the aramide, nylon and basalt-nylon hybrid cords.
  • Figure 2 is the graphic showing the modulus characterizing the load- elongation curve.
  • the inventive hybrid cord structure which is used in production of cord fabric supporting the tire structure used in vehicles and enables to eliminate the negative features by using fibers produced from different material together, comprises - base fiber which has negative and positive properties together according to the different fields of use and conditions in terms of mechanical features such as thermal stability (shrinkage), and which is preferably manufactured from nylon, aramide material to be used in vehicle tire, and - enhancing basalt fiber which is used being twisted with the base fiber and improves the mechanical features of the base fiber in the areas where it corresponds in vehicle tire by being used in different densities according to the said areas.
  • thermal stability shrinkage
  • the features of the hybrid cords change according to the type, layer number, twist direction and twist level, linear density of the material (dtex).
  • the linear density range of the basalt fiber in the hybrid cord is 680-6000 dtex, and the linear density range of NY66 fiber which is the base fiber preferred in the invention is 940-2800 dtex.
  • the weight ratio of the basalt inside the hybrid cord varies between 10% and 80% for all structures. Preferably the said ratio can be between 40% and 60%.
  • the twist direction of the cord is in Z or S direction
  • the twist direction of basalt and base fibers can be Z or S.
  • the twist directions of basalt and base fibers are the same and the layered cord structure has opposite twist direction.
  • the twist level of each fiber for hybrid cord should be between 100 tpm and 800 tpm, and the twist level of the hybrid cord can be 100 tpm and 800 tpm.
  • the layered twist level and the twist level of each fiber are the same, and it is between 200 tpm and 600 tpm.
  • the most preferred twist level is between 250-350 tpm.
  • basalt and/or Nylon fibers can be used more than once.
  • Basalt-Nylon hybrid cord can be used as cap ply strip in pneumatic tires.
  • Basalt-Nylon hybrid cord can be used as reinforcement material in carcass in pneumatic tires.
  • Basalt Nylon hybrid cord can be applied as narrow strips such that it will make 0- 5 degrees with the tire circumferential axis in tire cap plies.
  • the basalt-Nylon hybrid cord number of the said strips in decimeter can vary between 50 and 150.
  • the number of cords in decimeter is between 80 and 120, the most preferred comprises 90 to 110 cords per decimeter.
  • the density structures of NY66 which is the preferred basalt fiber and base fiber in the inventive hybrid cord structure are as follows:
  • Basalt fiber is a high performance fiber which is obtained from completely natural sources.
  • the production cost of basalt which is a completely natural and environmental friendly product in terms of both the production process and the obtained product is very low. There is no waste during production, it is produced with 100% efficient process.
  • Basalt fiber is a high performance fiber which is obtained from volcanic rocks.
  • a hybrid cord product having stronger and superior features is realized by combining cords with different features.
  • the thermal stability of which is higher with the basalt fiber the mechanical features of which can be controlled and do not change.
  • the disadvantages of nylon fiber the modulus of which is not enough at high speeds in cap ply layer and the aramide fiber which makes the production difficult with its high modulus during tire vulcanization stage.
