Fluorine-free water-repellent polyester staple fiber
Facing global environmental challenges, we fully recognize the potential risks that conventional fluorinated water-repellent fibers may pose to both the environment and human health during both production and use.
Traditional water-repellent fibers largely rely on fluorinated compounds (such as PFOA and PFOS), which are difficult to degrade, tend to accumulate in the environment, and can harm ecosystems. As environmental awareness continues to grow, the market demand for fluorine-free water-repellent fibers is steadily increasing. In response, fluorine-free water-repellent polyester staple fibers have emerged—featuring a unique, non-fluorinated finishing agent that imparts water-repellent properties to the fibers while eliminating the environmental risks associated with conventional fluorinated chemicals.
Fluorine-free, water-repellent polyester staple fibers feature a chemically cross-linked water-repelling film on their surface, characterized by highly oriented hydrophobic molecules and low surface tension. When water droplets come into contact with the fiber surface, their cohesive forces—driven by the lower surface energy—are stronger than the adhesive forces between the water molecules and the fiber, preventing the droplets from spreading out. Instead, water forms beads that easily roll off, effectively repelling water. This unique property not only ensures water beads form and roll away on the fabric surface but also maintains excellent water-repellent performance even after multiple wash cycles. The fabric’s water-repellent capability has been rigorously tested according to the AATCC 22 standard, scoring above 90 points, demonstrating outstanding durability and long-lasting water resistance. Additionally, it has passed the AATCC 193 test, achieving a rating of Level 7, highlighting its exceptional ability to repel moisture while remaining breathable.
