At the forefront of textile technology, we have successfully incorporated hydrophilic groups into the hydrophobic PET component of Sorona through precision modification technology. This innovation not only preserves the excellent properties of the fibers, It also endows it with unique moisture absorption and quick drying characteristics. The unique spring like structure of Sorona not only enhances the elasticity and comfort of the fabric, but also cleverly promotes the rapid penetration and evaporation of water molecules. This yarn has achieved a dual leap in both moisture absorption and sweat wicking efficiency. The core of this modification technology lies in balancing the water repellent and hydrophilic functions of fibers, optimizing their morphological structure, and leading textile materials moving towards higher performance and more environmentally friendly direction.
