What is Polyester?

1.Material composition

Polyester is a synthetic fiber of a species, which is based on purified terephthalic acid (PTA) and ethylene glycol (EG) as raw material by esterification or transesterification and polycondensation of prepared fiber-forming polymer, after spinning and filaments formed after processing. We are known as "Dacron" That's it made of.

2.Performancev

Polyester synthetic fiber technology are the three most simple one, the price is relatively cheap. It has a variety of characteristics, features mainly reflected in:

• High strength. Impact resistance strength than nylon high 4 times, 20 times higher than that of viscose fibers.
  
• Good elasticity. Elastic strength nears elastic strength of wool, and therefore, the production of polyester textile does not fold.
  
• Lightfastness, good wear resistance. Second only to wear nylon, and nylon is the best wear resistance of the material. Than natural, synthetic fibers are better.
  
• Preservative. There is a strong acid and alkali and UV resistance.
  
• Not faded, but poor dyeability.
  
• Smooth crisp, washable and quick drying advantages. But feel rough. Comfort is not good enough, breathability and moisture absorption somewhat less than other materials.
