Rapid drying times make polyester materials easy to wash and maintain

  Drawbacks of Polyester Materials

 
While polyester materials are incredibly popular, manufacturers should keep a few drawbacks in mind. Notably, polyester materials are not always biodegradable; polyesters tend to build up static a lot, and they commonly hold odors for a longer duration than many other materials. This may make them somewhat less suitable for certain applications. They are also limited in terms of breathability, too, which can make them a little uncomfortable to wear for extended durations of time.

  How are Polyester Materials Used?

 
Among the most common applications for polyester materials in the modern world include clothing and equipment manufacturing, largely for their excellent value for money.
