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