Claims
- 1. A process for treating organic fibers which comprises applying to the organic fibers an organopolysiloxane composition which can be stored under substantially anhydrous conditions, but when exposed to moisture cures to a solid consisting essentially of:
- (A) a diorganopolysiloxane having terminal Si-bonded hydroxyl groups;
- (B) an organosilicon compound selected from the group consisting of organosilanes of the formula RSiR'.sub.n X.sub.3-n, in which R is a monovalent radical having at least two amino groups which are bonded to silicon via silicon-carbon bonds, R' is selected from the group consisting of an alkyl and aryl radical, X is selected from the group consisting of alkyl and substituted alkyl radicals having from 1 to 14 carbon atoms per radical which are bonded to silicon via oxygen, n is 0 or 1, partial hydrolysates of said organosilanes and mixtures thereof and
- (C) an organosilane other than (B) having the formula R"Si(ON.dbd.CX).sub.3, where R" is selected from the group consisting of monovalent hydrocarbon radicals and halogenated monovalent hydrocarbon radicals and X is selected from the group consisting of R".sub.2, a bivalent hydrocarbon radical and a halogenated hydrocarbon radical and an organic solvent, and thereafter curing the composition on the organic fibers.
- 2. The process of claim 1, wherein a condensation catalyst (D) is present.
- 3. The process of claim 2, wherein the catalyst (D) is a tin acylate.
- 4. The process of claim 1, wherein the composition is cured at room temperature.
- 5. The process of claim 4 wherein the organosilane (C) composition is present in the organic solvent in an amount of from 1 to 30 percent by weight based on the weight of organosilicon compounds (A) and (B).
- 6. The process of claim 1, wherein the monovalent radical contains carbon, hydrogen and an aminonitrogen.
- 7. The process of claim 1, wherein the monovalent radical contains carbon, hydrogen, oxygen and an aminonitrogen.
- 8. The process of claim 1, wherein the organosilane (C) is present in an amount of from 1 to 30 percent by weight based on the weight of organosilicon compounds (A) and (B).
- 9. The process of claim 1, wherein the organosilane (C) is methyltris-(ethylmethylketoximo)-silane.
- 10. The product obtained from the process of claim 1.
