Abstract
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 a 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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
128 words
A fiber-treatment agent composition comprising (A) an organopolysiloxane represented by the formula wherein R is a monovalent hydrocarbon group; A is an R group or a group with the formula -R¹(NHCH₂CH₂) a NH₂; R¹ is a divalent hydrocarbon group; a = zero to 10; p and q are zero or more; with the proviso that p + q = 10 to 2,000, and there is at least one -R¹(NHCH₂CH₂) a NH₂ group in each molecule; and (B) 0.2 to 5.0 moles, per 1 mole of primary and secondary amino groups in component (A), of a compound represented by the formula R²O(C₂H₄O) b R³COOH wherein R² is a monovalent hydrocarbon group having 10 to 20 carbon atoms, b is at least one, and R³ is a divalent hydrocarbon group.
Claim 2
Dependent Claim
128 words
A fiber-treatment agent composition comprising (A) an organopolysiloxane represented by the formula wherein R is a monovalent hydrocarbon group; A is an R group or a group with the formula -R¹(NHCH₂CH₂) a NH₂; R¹ is a divalent hydrocarbon group; a = zero to 10; p and q are zero or more; with the proviso that p + q = 10 to 2,000, and there is at least one -R¹(NHCH₂CH₂) a NH₂ group in each molecule; and (B) 0.2 to 5.0 moles, per 1 mole of primary and secondary amino groups in component (A), of a compound represented by the formula R²O(C₂H₄O) b R³COOH wherein R² is a monovalent hydrocarbon group having 10 to 20 carbon atoms, b is at least one, and R³ is a divalent hydrocarbon group.
