What Is Polyester Density?
Polyester density is the mass or weight of polyester material per unit volume. It determines how much fibers are packed together in a given volume of polyester. High-density polyester means there is more fiber packed together per unit volume, resulting in a more durable and heavier fabric. Conversely, low-density polyester means that the material is lighter and less durable. Polyester density is an important factor in determining the strength, durability, and other physical properties of the polyester material.
