ABSTRACT:
A composition and method for providing a non-formaldehyde durable press finish to cellulosic fabrics by employing polyphosphinocarboxylic acids are disclosed. The polyphosphinocarboxylic acid is preferably polyphosphinoacrylic acid, and is optimally used in combination with phosphonoalkylpolycarboxylic acid, and, for cost effectiveness, a low-cost polycarboxylic acid such as citric acid. The catalyst for the curing reaction is preferably a phosphorus-containing acid or alkali metal salt thereof such as a mixture of sodium monophosphate and sodium hypophosphite.
