UPF 50+ Anti-UV Sun Protection Polyester Filament Yarn is produced via an advanced modified melt-spinning process that uniformly incorporates nano-scale inorganic UV-blocking agents (such as titanium dioxide) directly into the polyester polymer. Available in standard specifications ranging from 30D to 150D / 24F to 144F (including FDY and DTY filaments), supporting fine-denier customization for lightweight UV-protective fabrics.

Primary Applications: Widely used in sun-protective jackets, lightweight windbreakers, outdoor sportswear, cycling apparel, cooling sleeves, sun hats, and sunshade textiles.

Key Advantages:

Broad-Spectrum UV Protection: Blocks over 98% of harmful UVA and UVB rays, achieving a UPF 50+ rating for all-day skin defense.

Permanent & Wash-Resistant Performance: UV-blocking particles are permanently embedded inside the fiber core, ensuring long-lasting protection that will not wash off or degrade over time.

Cool, Comfortable & Durable: Combines polyester's high strength, wrinkle resistance, and quick-drying capabilities with a smooth texture, delivering lightweight breathability, a cool hand-feel, and excellent dimensional stability.
