1. High strength. The short fiber strength is 2.6~5.7cN/dtex, and the high strength fiber is 5.6~8.0cN/dtex. Due to its low hygroscopicity, its wet strength is essentially the same as the dry strength. The impact strength is 4 times higher than that of cotton and 20 times higher than viscose.

2. Good elasticity. The elasticity is close to that of wool, and when it is stretched by 5% to 6%, it can almost completely recover. The wrinkle resistance is superior to other fibers, that is, the fabric is not wrinkled, and the dimensional stability is good. The modulus of elasticity is 22~141cN/dtex, which is 2~3 times higher than that of cotton. Polyester fabrics have high strength and elastic recovery, so they are durable, wrinkle-free and non-iron.

3. Good heat resistance. The heat-resistant polyester is made by melt spinning, and the formed fiber can be further heated and melted. It belongs to thermoplastic fiber. The melting point of polyester is relatively high, and the specific heat capacity and thermal conductivity are small, so the heat resistance and heat insulation of polyester fiber are obtained. Sex is higher. It is the best among the fibers.

4. Good thermoplasticity and poor resistance to melting. Polyester is the most heat-resistant fabric in synthetic fabrics due to its smooth surface and tight internal molecules. It is thermoplastic and can be made into pleated skirts with long pleats. At the same time, polyester fabrics have poor resistance to melting, and they form holes in the presence of soot and Mars. Therefore, wear should avoid contact with cigarette butts, sparks, etc.

5. Good wear resistance. Wear resistance is second only to cotton with the best abrasion resistance, better than other natural and synthetic fibers.
