Introduction In functional insole design, the performance of the top-cover textile determines the user’s immediate tactile experience. Coolmax®, a patented moisture-wicking fiber developed by Invista, is globally recognized as the expert in thermal regulation and perspiration management. Aybroad seamlessly integrates Coolmax® technology with core insole materials to create an all-weather dry-foot system.
Core Technology: Engineered Fibers and Capillary Action
The secret of Coolmax® lies in its specially engineered fiber cross-sections, featuring four or six-channel designs. Compared to standard round fibers, this irregular structure vastly increases surface area and creates powerful capillary action. It rapidly transports sweat away from the skin, diffusing it across the fabric surface for accelerated evaporation. Its drying speed is several times faster than natural cotton, effectively lowering the foot's surface temperature.
Aybroad’s Integration Expertise: Breathable Lamination & Wicking Systems
-
Breathable Lamination: Traditional bonding often uses excessive adhesive, which clogs moisture-wicking pores. Aybroad utilizes Hot-melt Web or Scatter Coating techniques, ensuring high peel strength while preserving 100% of the fiber's wicking capabilities.
-
Air-Flow Engineering: We typically combine Coolmax® top covers with perforated EVA or open-cell PU bases to create a 3D ventilation network. This ensures the fabric remains non-sticky even in humid conditions, significantly reducing the risk of friction-induced blisters.
Applications
Coolmax® is an essential configuration for summer collections, high-intensity athletic lines, and long-distance travel insoles. Aybroad assists clients in the brand authorization process, enhancing product marketability with official hangtags.
