1. High intensity
The short fiber strength is 2.6 to 5.7 cN/dtex, and the high strength fiber is 5.6 to 8.0 cN/dtex.
2. Good flexibility
The elasticity is close to that of wool, and when it is stretched by 5% to 6%, it can be almost completely recovered.
3. Corrosion resistance
Resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decompose. also
4. Good light resistance
Polyester fabrics have better lightfastness, and their lightfastness is better than natural fiber fabrics except for acrylic fibers.
5. Good heat resistance
Polyester is the most heat-resistant fabric in synthetic fabrics. It is thermoplastic and can be made into pleated skirts with long pleats.
6. Good wear resistance
Wear resistance is second only to nylon with the best abrasion resistance, better than other natural and synthetic fibers.
7. Good chemical properties
Polyester fabrics are resistant to a wide range of chemicals. Acid and alkali have little damage to them, and they are not afraid of mold and are not afraid of insects.
