Water repellent textile finishes and method of making

A process of treating textiles comprising the steps of:

• A) providing an aqueous emulsion comprising a composition comprising:
• 1) a compound of the formula:
• A1(Si[R1]2O)u(Si[R2][E]O)vSi(R3)2A2;
• 2) a compound of the formula:
• B1(Si[R4]2O)w(Si[R5][G]O)xSi(R6)2B2;
• and
• 3) a crosslinker selected from the group consisting of:
• a) compounds of the formula:
• Z1(Si[R7]2O)y(SiH[R8]O)zSi(R9)2Z2;
• and
• b) compounds of the formula:
• 12
• wherein
• 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;
• D is selected from the group consisting of hydrogen, substituted or unsubstituted C1-C12 hydrocarbon moieties, OR14, and moieties of the formula:
• 13
• R10 and R15 are independently selected from the group consisting of hydrogen, substituted or unsubstituted C1-C12 hydrocarbon moieties, and OR13;
• R11, R12, R13, R14, and R16 are independently selected from the group consisting of C1-C6 hydrocarbon moieties;
• n is 1, 2, or 3;
• and
• a is 0, 1, or 2.
• 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.
