Sports fabrics (also known as Activewear or Technical textiles) are specialized, performance-engineered materials designed to keep the wearer comfortable, regulated, and supported during physical activity. Unlike traditional materials like cotton, these fabrics are built around core functional benefits: Moisture Management: They use moisture-wicking properties (like polyester or nylon blends) to actively draw sweat away from the skin and quickly spread it to the fabric's outer surface, where it evaporates. Breathability: They allow for high air circulation and water vapor permeability, which helps the body dissipate heat and prevents overheating. Flexibility & Support: Many incorporate high-stretch fibers like Spandex (Lycra/Elastane) to offer four-way stretch, recovery, and compression, providing optimal mobility and muscle support. In short, sports fabric is a category of functional materials, usually synthetic or specially treated natural fibers, where performance (like quick-drying and temperature control) is prioritized over traditional aesthetics
