High tenacity yarns are a crucial component in the manufacturing of high-performance tyres. Tyres are subjected to various kinds of stress and strain during their lifetime, including the weight of the vehicle, road friction, and impact from bumps and potholes. High tenacity yarns are turned into fabrics that help to reinforce the rubber compound of the tyre and provide it with the strength and durability necessary to withstand these forces.
Which yarns are used in tyres?
The most commonly used high tenacity yarns in tyre manufacturing are nylon and polyester yarns. Kevlar was also originally invented during DuPont’s efforts to make car tyres lighter. These synthetic fibres have high tensile strength, which means they can withstand a lot of tension without breaking. The yarns are typically coated with a layer of adhesive to help bond them to the rubber compound, and then arranged in a specific pattern to create layers of reinforcement within the tyre. This adhesive is necessary because synthetic filament yarns can be very slippery.
What do yarns in tyres do?
One of the key advantages of using high tenacity yarns is the improved handling and performance of the tyre. The arrangement of the yarns in the rubber compound can be customized to provide specific characteristics such as improved traction, better handling, and increased stability at high speeds. This means that tyre manufacturers can tailor their products to meet the specific needs of different types of vehicles and driving conditions.
Another advantage of using high tenacity yarns in tyres is that they improve the tyre’s resistance to punctures and cuts. The yarns form a network of fibres within the rubber compound, which helps to distribute the load evenly across the surface of the tyre. This means that when the tyre encounters sharp objects or rough terrain, the load is spread out and the tyre is less likely to be punctured or cut.
Finally, using high tenacity yarns in tyres is that they improve the tyre’s overall durability. The yarns help to prevent the rubber from cracking or splitting over time, which can occur as a result of exposure to heat, UV light, and other environmental factors. By providing additional strength and support to the rubber compound, the high tenacity yarns help to extend the lifespan of the tyre and reduce the need for replacement.
High tenacity yarns are a crucial component in the manufacturing of high-performance tyres. They provide the tyre with the strength, durability, and resistance to punctures and cuts necessary to withstand the stresses and strains of everyday use. By incorporating high tenacity yarns into their products, tyre manufacturers can create tyres that offer improved performance, handling, and safety for drivers and passengers alike.
