Water and Oil Repellent and Durable Press Finishes for Cotton Based on a Perfluoroalkyl-Containing Multi-Epoxy Compound and Citric Acid

摘要

A novel perfluoroalkyl-containing multi-epoxy compound (PFME), designed and synthesized in our laboratory, is applied to cotton fabrics by the pad-dry-cure process to give durable water and oil repellency by developing permanent covalent bonds to the textile substrate. The specimens pretreated by citric acid are further treated with PFME. The dual finished cotton shows both durable water and oil repellent appearances and durable press properties. The optimum treatment conditions for the dual finishing are discussed.
