Polyester Knitted Fabrics: Why Are They Dominating Modern Textile Applications?

What makes polyester knitted fabrics the preferred choice for today's activewear, fashion, and technical textiles? This versatile material combines synthetic fiber advantages with knitting technology's flexibility to create fabrics meeting diverse performance demands. Let's examine what sets these textiles apart.

How Are Polyester Knitted Fabrics Constructed?

Knitting Techniques Matter

• Weft knitting (circular/jersey): Produces stretchy, drapey fabrics

• Warp knitting (tricot/raschel): Creates dimensionally stable textiles

• Specialty constructions (interlock, piqué): For specific performance needs

Fiber Engineering Innovations

• Microfiber variants (0.5-1.0 denier) for ultra-soft hand feel

• Cross-section modifications (tri-lobal, hollow core) for enhanced properties

• Blend combinations with spandex, cotton, or nylon for optimized performance

What Performance Advantages Do They Offer?
