In January 2026, a new trend emerged in the field of textile functional finishing. Fabric water repellents have undergone multiple stages of technological iteration and are accelerating towards green and environmental protection. Early water repellents were mainly aliphatic hydrocarbon fluorine-free products, but they failed to meet market demand due to poor wash and wear resistance or insufficient environmental protection. Since then, researchers have continued R&D, driving products into the silicone, fluorosilicone and organic fluorine stages in turn. The comprehensive properties of water repellents such as hydrophobicity, oleophobicity, heat and stain resistance have been greatly improved, enabling them to adapt to harsh service environments and gain market recognition. Although fluorinated water repellents have outstanding performance, their complex production, high cost and poor degradability are contrary to the concept of green development. At present, the industry has formed four mature categories: fluorine, silicone, fluorosilicone and fluorine-free. The market shows a trend of returning to fluorosilicone and fluorine-free water repellents, and a variety of special water repellent products have emerged as the times require, providing customized solutions for different textile scenarios such as cotton, chemical fiber and shoe materials. Greenization and specialization have become the core development directions of fabric water repellents. For more information, please click: https://www.tiktok.com/@mia_iota/video/7597717976720149782
