Abstract
A nylon 6.6 yarn suitable for a tire cord reinforcement for pneumatic tires includes higher than 12.0 g/dtex Tensile Reinforcement Index (TRI) and tenacity between 9.3 g/dtex-10.5 g/dtex, where the TRI is defined as: TRI (g/dtex)=Tenacity (g/dtex)+Stress at 7% Elongation. The nylon 6.6 yarn is suitable for using as tire cord reinforcement in pneumatic tires.
Claims7
A nylon 6.6 yarn for a tire cord reinforcement for pneumatic tires comprising a Tensile Reinforcement Index (TRI) and a tenacity, wherein the TRI is defined as below:
- TRI (g/dtex)=Tenacity (g/dtex)+Stress at 7% Elongation;
- wherein the TRI is higher than 12.0 g/dtex and lower than 13.5 g/dtex, wherein the tenacity is between 9.3 g/dtex-10.5 g/dtex, and wherein the elongation at break is 18.8% when measured at 24° C.±1° C. and 55% Relative Humidity (RH)±2%.
