Abstract
Abstract Alkoxylation products in form of solutions in organic solvents or, preferably, in form of aqueous emulsions, stable against hydrolytic influences are used in a process for finishing textile materials to impart to these an excellent soft, superficially smooth fell connected with the improvement of tearing strength, abrasion resistance and sewability. The alkoxylation products are obtained by alkoxylation of hydrogen organopolysiloxanes, in particular of methyl hydrogen polysiloxanes with monovalent saturated and/or unsaturated alcohols having 4 to 22 C atoms.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
46 words
A process for finishing a textile which comprises applying to the textile a diluted composition which contains an emulsified or dissolved alkoxylation product of a hydrogen organopolysiloxane with at least one monovalent unsaturated alcohol having 11 to 18 carbon atoms, and heating the treated textile materials.
Claim 2
Dependent Claim
46 words
A process for finishing a textile which comprises applying to the textile a diluted composition which contains an emulsified or dissolved alkoxylation product of a hydrogen organopolysiloxane with at least one monovalent unsaturated alcohol having 11 to 18 carbon atoms, and heating the treated textile materials.
Claim 3
Dependent Claim
25 words
A process according to claim 1 wherein the hydrogen atoms of the hydrogen organopolysiloxanes are alkoxylated to at least 75 mole % with the alcohol.
Claim 4
Dependent Claim
25 words
A process according to claim 1 wherein the hydrogen atoms of the hydrogen organopolysiloxanes are alkoxylated to at least 90 mole % with the alcohol.
Claim 5
Dependent Claim
18 words
A process according to claim 1 wherein the hydrogen organopolysiloxane to be alkoxylated is a methyl hydrogen polysiloxane.
Claim 6
Dependent Claim
20 words
A process according to claim 1 wherein the said heating is effected at temperatures of from 80° to 160° C.
Claim 7
Dependent Claim
17 words
A process according to claim 1 wherein the composition comprises an aqueous emulsion of the alkoxylation product.
