SiTEX® FIR Yarn
Mineral-Infused Far-Infrared Yarn
Built Into the Fiber. Not Coated On.
Patented SiTEX® FIR Yarn integrates more than 20 natural minerals directly into nylon or polyester during spinning. The built-in mineral technology provides durable far-infrared functionality designed for performance apparel, wellness textiles, sportswear, recovery wear, and functional fabrics.
20+ Natural Minerals
Mineral-infused technology engineered for stable far-infrared emission.
Fiber-Level Integration
Minerals are embedded directly into the yarn fiber during spinning.
Wash-Durable Performance
Built-in FIR functionality remains effective after repeated laundering.
Recycled Fiber Options
Available with GRS-certified recycled polyester and nylon.
SiTEX® Far-Infrared Yarn Manufacturing Process
Unlike coated fabrics, SiTEX® integrates over 20 types of nano-ground natural minerals, such as tourmaline, germanium, and other FIR-active elements, directly into nylon or polyester polymer structures during the spinning process. This ensures that the yarn’s performance remains durable and effective throughout the lifecycle of the product, even after repeated washing and wear.
SiTEX® Dual-Layer FIR Yarn Structure
SiTEX® FIR Yarn uses a patented dual-layer fiber structure that combines a functional core yarn with a secondary sheath yarn. This construction enhances yarn stability and supports consistent far-infrared performance for functional textiles, performance apparel, and wellness applications.
SiTEX® FIR Yarn is a patented, mineral-infused far-infrared functional yarn developed by HITEK TEXTILE. Its performance is supported by third-party testing for FIR emissivity, antibacterial activity, wash durability, and functional textile performance.
