As global consumers demand high-performance swimwear, international buyers face critical sourcing challenges: meeting stringent UPF 50+ ultraviolet protection standards, ensuring quick-dry waterproof performance, and providing verifiable RPET eco-friendly certification. As a leading Hersteller von Boardshorts mit 23 Jahre Exporterfahrung, Yongrui integrates advanced textile engineering with certified sustainable supply chains to deliver premium swim trunks for over 200 global brands.
UPF 50+ Protective Fabric Technology
Achieving a certified UPF 50+ rating requires combining structural high-density weaving with yarn-level chemical defense. Standard lightweight swim fabrics allow UV radiation to penetrate loosened fiber gaps when stretched.
To prevent UV penetration, we utilize tight 240T to 300T polyester constructions embedded with non-toxic titanium dioxide particles. This hybrid approach mechanically reflects and absorbs harmful radiation, keeping solar barriers active after extended saltwater exposure.
Raw Yarns with TiO2 Embedment → 240T/300T High-Density Weaving → AATCC 183 Testing → UPF 50+ Certification
| Performance Metric | Standard Fabric | Yongrui UPF 50+ Board Shorts |
| UVA/UVB Protection | 85-90% Blockage | 98%+ Blockage |
| UPF Rating | UPF 15 – 20 | UPF 50+ |
| Wash Durability | Fades after 10 washes | 50+ Industrial Washes |
| Fabric Density | 190T – 210T | 240T – 300T High Density |
💡 Häufig gestellte Fragen
Q: How do board shorts achieve a certified UPF 50+ rating without sacrificing breathability?
A: Certified UPF 50+ protection is achieved by combining high-density 240T/300T weaving structures with embedded $\text{TiO}_2$ UV-absorbing fibers. This hybrid approach mechanically blocks 98%+ of ultraviolet rays while preserving micro-ventilation pathways for optimal airflow and quick-drying performance.
Waterproof And Sunscreen Testing Standards
When swimwear absorbs water, wet fibers swell and open the fabric matrix, potentially compromising UV defense. High-performance surf trunks require durable water repellency to maintain structural integrity in heavy surf conditions.
Our production applies fluorocarbon-free DWR (Durable Water Repellent) treatments that force ocean water to bead off instantly. This hydrophobic barrier prevents waterlogging, reduces surf friction, and ensures sun defense remains fully active when wet.
Hydrophobic DWR Application → Spray Testing (AATCC 22) → Hydrostatic Pressure Test → Wet UPF 50+ Verification
| Testing Standard | Evaluation Target | Yongrui Performance Level |
| AATCC 22 Water Repellency | Surface water shedding ability | Grade 90-100 (Superior Beading) |
| Wet UPF Rating | UV barrier retention after water immersion | UPF 50+ (Uncompromised Defense) |
| Color Fastness to Saltwater | ISO 105-E02 compliance | Grade 4.5+ (No Fading or Bleeding) |
💡 Häufig gestellte Fragen
Q: Does fabric water repellency affect the UPF 50+ sun protection rating of wet board shorts?
A: No. Advanced DWR coatings keep the fabric fibers from absorbing moisture. Because water saturation can otherwise cause fibers to swell and open the weave, hydrophobic quick-dry treatments ensure the UPF 50+ ultraviolet barrier stays intact even when fully submerged in saltwater.
