TR stands for the composition in the fabric, n stands for nylon, r stands for rayon and t stands for polyester. Generally, if it is Roman cloth, it is nylon rayon Roman cloth and polyester rayon Roman cloth. The proportion of ingredients is generally 65, 35. That's 65% nylon, 35% rayon, 65% polyester and 35% rayon. T generally refers to polyester, such as T/C and TRS cloth. P is often used to indicate polyester in silk and wool, but it is also used to indicate PA nylon. The official abbreviation should be "t" Polyester fabric is a kind of chemical fiber clothing fabric widely used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention, so it is suitable for outdoor products such as coats and clothes, various bags and tents.

Main functions of polyester

1, improve high temperature stability, improve high temperature stability. Because of the three-dimensional distribution of polyester fiber monofilament, it has strong adsorption with asphalt without entanglement, and it can absorb too much free asphalt, thus increasing the viscosity and cohesion of asphalt. At the same time, due to the crisscross reinforcement and bridging, the fluidity of asphalt is reduced, the lateral displacement or flow of aggregate is limited, the high temperature stability is effectively improved, and the stability of fiber asphalt concrete is greatly improved.

2. The adsorption of fiber on asphalt improves the low-temperature crack resistance of asphalt concrete, thus improving the optimal asphalt content of asphalt concrete. The high asphalt content makes the fiber asphalt mixture maintain flexibility and high tensile strength at the low temperature of -40℃, effectively resist shrinkage stress, enhance the low-temperature crack resistance of the mixture, reduce the occurrence of temperature shrinkage cracks and prevent the development of reflection cracks.
