Abstract
Although widely used fluorine-based water repellents, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), have the advantages of excellent in water repellency, chemical stability, and maintenance of the original properties of fibers, their use are limited due to non-biodegradation and toxicity to human body. In this study, a non-fluorine repellent was synthesized through an emulsion polymerization process using nonionic and cationic emulsifiers, and stearyl acrylate, as a long-chain alkyl acrylate, in the presence of alkysiloxane resin in order to maximize water repellent effect. The synthesized water repellent was applied to a fiber substrate, dried and coated to evaluate the water repellency and surface properties through the contact angle measurement and AATCC 22 water repellency test.
