Polyester threads are widely used in the manufacture of rubber hose skeletons due to their good heat resistance, sufficient breaking strength, dimensional stability, light resistance, and corrosion resistance. However, some external factors include light, heat, high-energy radiation, mechanical forces, and mold-to-polymer damage, which can cause irreversible changes in polymers, degraded performance, and loss of use.
1. The degree of influence of pressure on the performance of the polyester thread is significantly greater than other factors, that is, his use environment is the biggest influencing factor.
2. When the pressure is constant, the speed of the performance of the polyester yarn is proportional to the temperature and time. That is to say, when the polyester thread is used in the same field, the higher the temperature and the longer the use time, the faster the aging speed.
3. When the thermal oxygen aging temperature exceeds 150 ° C, the performance of the polyester yarn is accelerated.
