Abstract:
A process of treating textiles comprising the steps of:A) providing an aqueous emulsion comprising a composition comprising: 1) an aqueous emulsion of a compound of the formula: A1(Si[R1]2O)u(Si[R2][E]O)vSi(R3)2A2; 2) an aqueous emulsion of a compound of the formula: B1(Si[R4]2O)w(Si[R5][G]O)xSi(R6)2B2; and 3) an aqueous emulsion of a crosslinker of the formula: Z1(Si[R7]2O)y(SiH[R8]O)zSi(R9)2Z2; â€ƒwherein R1, R2, R3, R4, R5, R6, R7, R8, and R9 are independently selected from the group consisting of alkyl groups of from 1 to 4 carbon atoms; E is a monovalent organic group comprising at least one epoxy group; A1 and A2 are independently selected from the group consisting of alkyl groups of from 1 to 4 carbon atoms and monovalent organic groups comprising at least one epoxy group; u is an integer from 1 to about 2000; v is an integer from 0 to about 200; the sum of u and v is from 1 to about 2200; G is selected from the group consisting of hydroxy and alkoxy; B1 and B2 are independently selected from the group consisting of alkyl groups of from 1 to 4 carbon atoms, hydroxy, and alkoxy; w is an integer from 1 to about 1000; x is an integer from 0 to about 50; the sum of w and x is from 1 to about 1050; Z1 and Z2 are independently selected from the group consisting of hydrogen and alkyl groups of from 1 to 4 carbon atoms; y is from 1 to about 1000; z is from 0 to about 2000; the sum of y and z is from 1 to about 3000; provided that component 1) comprises at least one epoxy moiety, component 2) comprises at least one alkoxy- or silanol moiety, and component 3) comprises at least two silicon bound hydrogen groups; B) providing a catalyst suitable to the aqueous emulsion that will promote a condensation reaction between compounds 1), 2), and 3), C) mixing the aqueous emulsion and the catalyst to form a mixture; D) applying the mixture to the textile; and E) heat treating the textile to form a condensation reaction product of compounds of 1), 2), and 3), whereby the textile has enhanced durability, water repellency, and softness.
