At its core, Dri-FIT is predominantly made of polyester microfiber. This isn’t your grandmother’s polyester. Today’s polyester is a highly engineered synthetic fiber boasting a range of desirable properties that make it ideal for performance apparel. Its inherent characteristics form the foundation upon which Dri-FIT’s moisture-wicking capabilities are built.
Polyester: A Versatile Polymer
Polyester is a synthetic polymer, a type of plastic derived from petroleum. Its creation involves a process called polymerization, where smaller molecules (monomers) are linked together to form long chains. These chains are then spun into fibers, which are woven or knitted into fabric. The specific type of polyester used in Dri-FIT is chosen for its strength, durability, and ability to be engineered with specific performance characteristics. This engineering is key to Dri-FIT’s unique functionality.
Why Polyester Works
Polyester offers several key advantages that make it an excellent choice for sportswear:
- Low Absorbency: Unlike natural fibers like cotton, polyester is hydrophobic, meaning it repels water. This is crucial for moisture-wicking because the fabric won’t become saturated with sweat. Instead, moisture is pushed to the surface.
- Strength and Durability: Polyester fibers are strong and resistant to stretching, shrinking, and tearing. This ensures that Dri-FIT garments can withstand the rigors of intense activity and frequent washing.
- Lightweight Feel: Polyester is a relatively lightweight fiber, contributing to the overall comfort and unrestricted movement that Dri-FIT apparel provides.
