Sweat Invisible Fiber

Sweat Invisible Fiber is a revolutionary functional fiber developed through a unique composite spinning and additive technology, which significantly increases the content of "functional compounds" in polyester/nylon-based products to approximately 7-12%. 

By leveraging the special properties of the additives, this new functional fiber combines multiple powerful features such as UV resistance, thermal insulation, sweat-free, anti-see-through, stain resistance, and antibacterial properties.

1. Sun Protection - UV Resistance  

The UV resistance reaches 5-10 times that of conventional UV-resistant fibers. Combined with fabric design, it can pass the most stringent UV protection test in the world: the American AATCC-183 standard (UV blockage rate of 99.8%).  

2. Thermal insulation

Infrared resistance effectively shields solar thermal radiation heat. The fabric exhibits excellent thermal radiation protection performance.  

3. Hidden Sweat - Sweatless Fabric  
Unique craftsmanship creates a diffuse reflection effect, rendering it visually imperceptible—sweating feels like not sweating, making movement more graceful.  

4. Stain Resistance

Easy to Clean  Strong stain absorption and easy washability. Combined with fabric design, it can achieve a level above 4.5 in the American AATCC-130 Stain Release Test Standard.  

5. Bacteriostatic - Antibacterial  
Features long-lasting antibacterial and bacteriostatic properties, effectively preventing body odor caused by excessive sweating.  
6. Privacy Protection - Anti-See-Through  
In conjunction with fabric design, it achieves a Japanese JIS-L1923 measurement method anti-see-through rating of Level 4 or higher in both dry and wet states.  

7. Unique Visual and Tactile Experience - The fabric is soft and matte, with a gentle, skin-friendly touch, closely resembling the effect of natural fibers.
