Abstract
A composition and method for treating fibers is based on a mixture of an organopolysiloxane having at least one amino-substituted hydrocarbon radical directly bonded to a silicon atom and a carboxylic acid containing at least one ethylene oxide unit. The carboxylic acid reacts with the amino radicals to reduce yellowing and oxidation of the fiber treatment. The composition and method provide non-yellowing fibers and a treatment agent that does not gel during use, such as when exposed to carbon dioxide and/or used to treat carbon fibers.
