Description

A TWISTED HYBRID CORD AND A PRODUCTION METHOD
THEREOF
Field of the Invention
The present invention relates to a twisted hybrid cord used as reinforcement for strengthening the physical features of the tires, and a production method thereof.
Background of the Invention
The vehicle tires are the composite structures formed of rubber and additives, and rubber reinforcement materials. The carcass and the bead wire are the carrier members in this structure. In tire technologies, the location of the carcass in the tire basically determines the type of the tire. According to the said definition, the tires wherein the carcass material is fixed by arranging crosswise and in opposite angle from one bead wire to the other bead wire are called bias tires, and the tires wherein the carcass material is placed parallel to the diameter direction from one bead wire to the other bead wire and fixed by winding the bead wire are called as radial tires.
In the most general way, the radial tires of the passenger vehicles are comprised of base, sidewall, bead, carcass and cap ply. The cord fabric is present in carcass and cap ply of the tire as the rubber reinforcement material. The carcass cord fabric forming the main construction of the tire carries the weight of the vehicle keeping the air pressure by providing strength and preserves the integrity of the tire. It also increases the strength against the impacts that will affect the sidewalls and base of the tire.
Centrifugal force generated upon the rotation of the tire affects the steel belt, and high speed and loading cause the overheating and expansion of the steel belt. In such cases, the said cap ply is placed on the steel fabric layer in order to provide the integrity of the steel belt. The cap ply produced from nylon cords shrinks with the increase in temperature, and this shrinkage force enables the structure to stay together by effecting on the steel belt layer. The steel belts, the movement of which inside the rubber is limited, are fixed by this way. Otherwise, the steel belts generate shear effect by moving in opposite direction on each other in each rotation of the tire. The said effect affects the rubber-steel composite and causes the layers to separate and the tire integrity to deteriorate.
When the tires of the vehicles such as truck, bus, construction equipment which are in heavy tire class are produced with radial technology, all layers have steel belts. In case they are produced with cross technology, multi layered nylon 66 or nylon 6 carcass cord fabrics are used in different layers (such as 4, 6, 8, 12 layers). Decreasing carcass cord fabric layers in cross tires makes the tire lighter and decreases the cost. Therefore, developing new hybrid cords the strength of which is increased and using the said cords in the vehicles tires provides big advantage.
German Patent document no DE4019447, an application known in the state of the art, discloses applying hybrid carbon fiber and glass fiber in tires of cars and motorcycle segments as bandage reinforcement in order to avoid heat during working.
United States Patent document no. US6667110, another application known in the state of the art, discloses that the steel/carbon fiber hybrids are used in order to increase aging and corrosion strength by targeting tires produced with steel carcass layer.
Japanese Patent document no. JP2004285498, another application known in the state of the art, discloses using carbon/aramide hybrid cords by aiming to acquire high strength and simultaneously excellent flexing resistance and dimensional stability in a single cord. The said document discloses the production of a cord where in the carbon fibers are present in the center twisted, whereas the aramide fiber is twisted again outside the carbon fiber.
As a result of the expansion of the cap ply under the effect of the centrifugal force, the steel cords reduce the durability of the tire by moving on each other. The density of the steel cord materials being high also increases the weight of the tire.
In carbon fibers, there is no shrinkage feature besides the lack of elongation feature. In case it is used alone, it cannot show shrinkage feature required in cap ply layer. Furthermore, because of the brittle structure of the carbon fibers, twisting around itself and around each other with conventional methods causes loss in strength. In twisting machines, the carbon fibers can easily be broken in transition pats and as a result of the angular movement generated because of the twisting. Because of all these reasons, using carbon fiber material with another material as hybrid will increase the life of the tire and decrease the weight.
Summary of the Invention
The objective of the present invention is to provide a twisted hybrid cord wherein the carbon and nylon fibers are wound being twisted around each other, and a production method thereof.
Another objective of the present invention is to provide a twisted hybrid cord which has high strength, elongation and shrinking properties, and a production method thereof.
A further objective of the present invention is to provide a twisted hybrid cord used as reinforcing material in vehicle tires, and a production method thereof.
Yet another objective of the present invention is to provide a twisted hybrid cord enabling homogenous temperature distribution to vehicle tire, and a production method thereof. Detailed Description of the Invention
The twisted hybrid cord developed to fulfill the objectives of the present invention is illustrated in the accompanying figures wherein
Figure 1 is the enlarged microscopic view of the Z*S twist of the twisted hybrid cord.
Figure 2 is the perspective view of the tire wherein a woven cap ply produced using twisted hybrid cord is present.
Figure 3 is the graphic wherein the tensile stress of the carbon-carbon (CF/CF) and carbon-nylon (CF/NY66) twisted cords under load.
Figure 4 is the graphic wherein the physical properties of 2000 dtex CF/CF in Z*S direction and 200*200 tpm (twists per meter) and 2000 dtex CF and 1400 dtex NY66 twisted and finished hybrid cord yarns under same conditions are compared.
Figure 5 is the graphic wherein the physical properties of 2000 dtex CF/CF in Z*S direction and 300*300 tpm (twists per meter) and 2000 dtex CF and 2100 dtex NY66 twisted and treated hybrid cord yarns in Z*S direction 315*315 tpm are compared.
The twisted hybrid cord production method (10) developed to fulfill the objective of the present invention comprises the steps of
twisting carbon fiber and nylon fiber together (11), treatment of hybrid cord (12), - dipping hybrid cord (121), curing the hybrid cord (122).
In the inventive twisted hybrid cord production method (10), first the carbon fiber is twisted together with the nylon fiber (11). The said fibers, which can be twisted in Z or S direction around each other, can be or cannot be twisted around themselves in Z or S direction previously. In the preferred embodiment of the invention, in 670-8000 dtex range, the carbon fiber (CF) twisted in Z direction around itself is used such that the twist amount will be in 50-400 tpm (twists per meter) range. The elongation and shrinkage value is zero since the said carbon fiber (CF) does not have viscoelastic structure. In the preferred embodiment of the invention, the said carbon fiber (CF) twisted in Z direction is twisted in S direction with nylon 6.6 in 470-2800 dtex range by winding in 50-400 tpm range, and by means of the viscoelastic structure of the nylon 6.6, elongation and shrinkage (flexibility) features are achieved in the hybrid cord which is prepared.
The twist direction defines the helix incline direction of a yarn or a cord when it is in vertical position. In twisting process, if the helix incline is applied in a way similar to the letter S, it is called "twist in S direction"; if the incline shows similarity with the letter Z, it is called as "twist in Z direction". Twisting a cord around itself is called as 1st level twist, and twisting with another cord is called as 2nd level twist. For example, if the cords are twisted around themselves in Z direction and twisted around each other in S direction, twisting is described as Z*S twist. In the preferred embodiment of the present invention, carbon fiber/nylon 6.6 fiber twisted hybrid cord in Z*S direction is realized.
The twisted cord obtained after hybrid twisting the carbon-nylon fibers (11) is subjected to treatment process (12). The treatment process (12) is performed by dipping the hybrid cord into a dipping solution comprising resorcinol, formaldehyde, styrene butadiene polymer latex and vinyl polymer latex. In the preferred embodiment of the invention, resorcinol in range of 0.5-5%, formaldehyde in the range of 0.5-8%, vinyl polymer latex in the range of 1-40% and styrene butadiene polymer latex in the range of 1-40% is used in the dipping solution. In the preferred embodiment of the invention, the total amount of solid in the dipping solution is in the range of 30-75% by mass. Then, the hybrid cords which are finished are cured at temperatures between 150 and 240 °C (12).
The parts in the figures are described as:
HC. Twisted hybrid cord
CF. Carbon fiber
NY66. Nylon fiber
L. Reinforced tire
CP. Cap ply
SB. Steel belt
The twisted hybrid cord (HC) produced with the inventive twisted hybrid cord production method (10) essentially comprises
at least one carbon fiber (CF) which is twisted as Z,
- at least one nylon fiber (NY66) which is twisted as S together with the carbon fiber (CF).
Producing reinforced vehicle tires (L) the physical features of which are enhanced, is possible by using the twisted hybrid cords (HC) produced with the twisted hybrid cord production method (10) in especially cap ply (CP) of the vehicle tires as reinforcement (Figure 2). During the use of the tire (L), the nylon fiber (NY66) present within the hybrid structure will keep the tire (L) together by shrinking because of the temperature and prevent the steel belt (SB) thereunder from performing shear movement.
In order to keep the physical features of the inventive twisted hybrid cord (HC) such as elongation/shrinkage in different ranges, different twisting levels and treatment conditions can be applied. By means of the inventive twisted hybrid cord production method (10), the CF/NY66 yarns twisted as hybrids enable tire production which is lighter and having more strength. The density of the steel belt (SB) is 7,75 gr/cm , whereas the density of the carbon fiber (CF) is 1,76 g/cm and the density of the nylon 6.6 (NY66) is 1.14 g/cm3.
The samples prepared as the inventive twisted hybrid cord (HC) are subjected to many tests. During tensile stress test, which is one of the these said tests, the elongation during breaking, the amount of the load in the determined elongation and the starting modulus are measured with Instron 4502 test device. The graphics wherein the several physical properties of carbon-carbon (CF/CF) and the inventive carbon-nylon (CF/NY66) twisted hybrid cords (HC) are compared are shown in Figures 3, 4 and 5.
The letters in Figure 3 refer to the following: CF/CF raw cord
