The high-performance polyester film fiber polyester anti-cracking cloth has a smooth surface, more uniform thickness, loss of transparency, stronger compatibility with asphalt mixtures, and more obvious use effects. Laying a layer of high-performance polyester cloth between the lower layer of the asphalt pavement structure and the surface layer can reduce and delay the pavement cracking caused by the overlap of the new and old pavement and the semi-rigid base layer, and prevent the damage of the base layer caused by water intrusion. Compared with ordinary anti-cracking cloth, the high-performance polyester anti-cracking cloth has lower elongation and higher tensile strength, which ensures the longer use effect of the product. The high-performance polyester anti-cracking cloth has stable chemical properties. After the updated technology and formula, it can prevent all kinds of chemical erosion and climate change, and has a wider application range. The high-performance polyester anti-cracking fabric will not be damaged below  degrees Celsius, and the temperature of the asphalt is controlled at degrees Celsius, which can make its stable performance unaffected.

The high-performance polyester anti-cracking cloth has good compatibility, which can form an effective waterproof layer. Even in the case of small cracks on the surface, it can basically prevent the surface water from infiltrating and avoid the road base materials from water. Erosion. Polyester includes polyester resin and polyester elastomer. Polyester resins include polyethylene terephthalate, polybutylene terephthalate and polyarylate. Polyester elastomer  is generally polymerized by dimethyl terephthalate, butanediol and polybutanol. The chain segment includes a hard segment and a soft segment, and is a thermoplastic elastomer.Polyethylene terephthalate  is a polymer compound. Polyethylene terephthalate  is produced by polycondensation of terephthalic acid  and ethylene glycol , and part of the PET is finally produced through underwater pelletizing.


Fiber-grade polyester chips are used to make polyester staple fibers and polyester filaments. They are the raw materials for polyester fiber companies to process fibers and related products. As the largest variety of chemical fibers, polyester occupies nearly 80% of the market share in the chemical fiber industry. The market changes and development trends of polyester series are the focus of the chemical fiber industry. At the same time, polyester is also used in bottles and films, which are widely used in the packaging industry, electronic appliances, medical and health, construction, automobiles and other fields. Among them, packaging is the largest non-fiber application market for polyester, and it is also the fastest growing field of PET. It can be said that polyester chips are an important intermediate product connecting petrochemical products and products in multiple industries.With the rapid development of China's economy, the apparent domestic consumption of polyester chips has increased rapidly. China's polyester production capacity is developing rapidly.


The fluctuation of world oil prices in  triggered changes in the international raw material market, and the development of China's polyester raw material industry was seriously lagging behind downstream industries. The domestic polyester raw material market was highly dependent on imports, which affected the 2004 polyester series market. It is completely dominated by the trend of polyester raw materials and continues to rise under the push of cost. While rising throughout the year, the weaker downstream price transmission of the petrochemical industry has led to a sharp decline in the efficiency of the polyester industry. The polyester fiber is on the verge of loss, and the polyester industry has entered a downturn in industry reshuffle. In this market situation, production companies especially need macro and micro analysis of the industry, and need to conduct research and investigation on international and domestic production, sales, market competition, market structure, and international trade to formulate corresponding strategies and development plans.
