The word ‘ply’ refers to the strands or folds in a tyre’s cord fabric, which provides strength to the tire. Like ply-wood composite, nylon tyres have a slant to the left and right. The fabric of these tires bonds with the rubber, but still retains its flexibility compared to radial tires.
Nylon tyre cord fabric provides strength to a tyre
The material used in a tyre’s cord is usually made of nylon. The fabric is heated and stretched to a specific degree. This process increases the material’s tensile strength and gives it a better flex fatigue resistance. Another factor influencing the strength of a nylon tyre cord is its abrasion resistance. The tensile strength of nylon tyre cord fabric depends on the twist factor.
The fabric is arranged in a tyre in layers called cap plies. A steel belt is inserted below the cap plies to increase the tensile strength of the tyre. The steel belt is 0.2 to 0.38 mm thick and is plated with zinc or copper. On the inside of the tyre, there is a thin layer of rubber known as radial plies. Finally, the sidewall is a rubber sheet that is 1.5 to 3.5 mm thick.
Major players in the global tyre cord fabric market include Kolon Industries Inc., Hyosung Corporation, and SRF Limited. Other key players include Teijin Ltd., Hyosung Corporation, Century Enka Limited, and SRF Limited. A global market research report reveals that more than 90 percent of the world’s tire cord fabric production is made of nylon.
Globally, the tire cord fabric market is segmented by geography. By value, the replacement segment will account for the largest share of the market during the forecast period, followed by OEMs. The replacement segment is largely driven by the growing number of passenger cars. In addition, an increasing number of radial tires will lead to a growing demand for nylon tyre cord fabric.
It bonds with rubber
A nylon tyre bonds with rubber using a self-condensing polymer of dihydrophenol. This is an acetone-like solvent that can be too harsh for some rubbers. Also, this solvent contains plasticizer, which can work its way to the surface and threaten to weaken the bond in the future. For this reason, acetone is not a good choice for this preparation.
The process of tyre wear and tear releases tiny particles into the air. A large portion of these particles remain on the road. In the study, the researchers looked at the size distribution of these particles and their chemical composition. Some of the particles were larger than others and therefore a higher fraction of them became airborne. However, the researchers found that the mass fraction that became airborne varied from 0.1% to 10%, whereas some studies reported up to 30%.
The adhesive used in the manufacture of a nylon tyre has two primary components: the cord and the compound. The nylon cord is dipped in adhesive solution and bonded to natural rubber-based compounds. Then the resin-rubber ratio of the RFL adhesive was optimised, and the pull-through load was studied by varying the curing and drying temperatures. Among the compounds, the RFL adhesive based on vinylpyridine latex exhibited better rubber-to-nylon tire cord bonding. The polymer used in the bonding process has formaldehyde donor to improve adhesion.
When a car tires has a tyre with a nylon tyre, it is most likely that it has been bonded with rubber, as rubber is more grippy than nylon. The other benefit of nylon is that it is more resistant to heat, so the tire will last longer. If you are using a nylon tyre on a road with good conditions, radials will outlast a nylon fabric bias tyre.
While natural rubber is still the preferred material for tire cords, the synthetic counterpart has several advantages over natural ones. It is less susceptible to oxidation, provides superior resistance to wear, and is quiet. Another advantage of the synthetic rubber is that it retains its high strength even in extreme temperatures. This gives a nylon tyre its green reputation. So, if you’re looking for a tyre, why not invest in a nylon one?
It retains flexibility compared to radial tires
Compared to radial tires, a nylon tyre has greater sidewall and tread flexibility. This allows for a more stable tread foundation. It also reduces rolling resistance and energy consumption. This type of construction was adopted by many car manufacturers in the early 1980s. By the end of the decade, radial tires made up almost all passenger vehicle tire shipments.
The steel wires in radial tyres become magnetized with use. They create an alternating magnetic field when they rotate. You can measure this with an EMF meter placed near the wheel well. For auto enthusiasts, performance and SPEEDS are the most important considerations. In addition to maintaining performance, they must also give adequate feedback. This is not always possible with radial tires.
Nylon tyres retain flexibility compared to radial tires. Nylon is composed of multiple layers that act like cushions. They are stiffer, but their flexible design allows them to retain flexibility. While radial tires are better for hot and wet weather, nylon may be more durable for off-road use. They may also resist impacts better than their radial counterparts.
The main difference between bias-ply and radial tires is the sidewall structure. Bias-ply tires feature sidewalls that are made of overlapping and cross-ply fabric. In contrast, radial tires feature sidewalls that are flexible and do not deform when subjected to high speed. A bias-ply tire‘s sidewall structure deforms as it reaches high speeds. On the other hand, a radial tyre’s crown belt stays stable around the circumference.
Despite the difference in sidewalls, a bias-ply tire‘s sidewall structure provides better traction in irregular surfaces, while a radial tire’s sidewalls are flexible. This allows them to provide a smoother ride when navigating uneven surfaces. In addition, a radial tire‘s sidewall structure delivers more pressure and wear evenly than a bias-ply tire’s sidewall structure.
Unlike bias-ply, a nylon-ply tyre has no overlapping sections. Its ply structure follows the track of a wheel, providing better traction and lower cost. A nylon tyre also retains flexibility compared to radial tires. If you’re in the market for new tires, it’s worth your while to invest in a radial one.
It is a bias-ply tire
If you’ve ever wondered what a bias-ply tire is, you’re not alone. The majority of drivers don’t know that this type of tire uses more rubber than a conventional tire. Bias-ply tires are great for off-roading or drag radials because of their higher flexibility. However, they wear more quickly and exhibit more rolling resistance, which can cause them to develop flat spots and wander in bad surfaces.
Bias-ply tires don’t have a capital “R” on the sidewall, but they sometimes have a capital “B” between the aspect ratio and rim size. Despite the name, Bias-ply tires are generally harder to find these days. Fortunately, there are specialty tire shops that carry them. However, they cost more than radials, and are not available everywhere.
While both types of tires are round and air-holding, they differ in their construction. Radial tires are more flexible and conform to uneven terrain. Bias-ply tires have more sidewall layers than radials, but their sidewalls tend to be stiffer and less confirming. Bias-ply tires can also be made to behave like radials by lowering their air pressure, but this exposes the sidewall to more potentially damaging objects, so they are more likely to suffer from punctures than radials.
Bias-ply tires are a type of tire made from alternating diagonal layers of rubberized nylon or polyester netting. Each ply is laid at a different angle than the one underneath it. The plies are then covered with rubber to form the tread. Although bias-ply tires are cheaper, they do not perform well on curves and bends. However, they can carry heavy loads.
A bias-ply tire is a type of non-directional tire. Its plys are overlapped so that they form a crisscross pattern. One ply is placed 30 to 40 degrees away from the direction of travel, while the other one is positioned the opposite way. If you saw the tire through, the overlapped plies would form an “X.” Bias-ply tires may have four, six, or even 10 plies.
