- This application discloses a non-fluorine-based water repellent composition and a method for producing a water-repellent textile product.
- Fluorine-based water repellents containing fluorine-based compounds are produced, for example, by polymerizing a monomer having a fluoroalkyl group. Articles treated with such fluorine-based water repellents have excellent water repellency. However, monomers having a fluoroalkyl group are an environmental burden. For this reason, non-fluorine-based water repellents that exhibit excellent water repellency have been internationally sought.
- Patent Document 1 discloses a water-based water repellent treatment agent that contains a non-fluorine-based water repellent component and a crosslinking component that can react with the water repellent component, and is composed of a hybrid emulsion in which the water repellent component and the crosslinking component are contained in one particle.
