Abstract:
A synthetic fiber treatment agent composition comprising(A) an amino group-containing polyorganosiloxane, where the terminals of the molecular chain are groups described by general formula where each R is selected from a C1 to C20 monovalent hydrocarbon group, a substituted C1 to C20 monovalent hydrocarbon group, and a hydroxyl group, with at least 80 mol % of all the R comprising monovalent hydrocarbon groups and substituted monovalent hydrocarbon groups; R2 is a C1 to C10 divalent hydrocarbon group; R3 and R4 are each selected from hydrogen atoms, C1 to C20 monovalent hydrocarbon groups, and substituted C1 to C20 monovalent hydrocarbon groups; a is an integer from 5 to 5; p is an integer from 0 to 2; q is an integer from 0 to 3, and r is 0 or 1, where (p+q+r)=3, and at least 30 mol % of all siloxane units per molecule are amino group-containing diorganosiloxane units described by general formula where R, R2, R3, R4, and a are the same as above and(B) a mixture of a polydiorganosiloxane where y is 0 and an amino group-containing polydiorganosiloxane in which y is an integer of 1 or more, in each case described by general formula where each A is selected from a trialkylsilyl group, a hydrogen atom, a C1 to C20 monovalent hydrocarbon group, and a substituted C1 to C20 monovalent hydrocarbon group; R, R2, R3, R4, and a are the same as above; x is an integer of 1 or more; where y/(x+y) is no more than 0.1.
