Abstract
Abstract A process for imparting to textile materials a soft handle finish is disclosed, wherein an acid amide of the formula CH.sub.2 ═C(X)--CO--NH--R.sub.1 or a reaction product from acrylic or methacrylic acid, or the lower alkyl esters of these acids, and an amine of the formula R.sub.1 --NH.sub.2 is used as a soft-handle agent. R 1 is alkyl or alkenyl having 14 to 22 carbon atoms, and X is hydrogen or methyl. There is preferably produced from the acid amide and commercial emulsifiers and wetting agents, in a novel composition, a concentrated high-pressure emulsion, which is diluted to give an aqueous preparation that is applied to the textile materials.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
A process for imparting to a textile material a soft handle, which process comprises immersing the material at 20° to 100° C. for 5 to 120 minutes in an aqueous preparation containing an acid amide of the formula CH.sub.2 ═C(X)--CO--NH--R.sub.1 or a reaction product from acrylic or methacrylic acid, or an alkyl ester thereof, and an amine of the formula R.sub.1 --NH.sub.2 wherein R 1 is alkyl or alkenyl of 14 to 22 carbon atoms and X is hydrogen or methyl, and subsequently drying the material at 50° to 150° C.
Claim 2
Dependent Claim
91 words
A process for imparting to a textile material a soft handle, which process comprises immersing the material at 20° to 100° C. for 5 to 120 minutes in an aqueous preparation containing an acid amide of the formula CH.sub.2 ═C(X)--CO--NH--R.sub.1 or a reaction product from acrylic or methacrylic acid, or an alkyl ester thereof, and an amine of the formula R.sub.1 --NH.sub.2 wherein R 1 is alkyl or alkenyl of 14 to 22 carbon atoms and X is hydrogen or methyl, and subsequently drying the material at 50° to 150° C.
Claim 3
Dependent Claim
27 words
A process according to claim 1 in which there is used the acid amide of the formula CH.sub.2 ═C(X)--CO--NH--(CH.sub.2).sub.17 --CH.sub.3 in which X is hydrogen or methyl.
Claim 4
Dependent Claim
32 words
A process according to claim 1 in which the preparation contains 0.1 to 0.5 percent by weight, relative to the dry textile material, of the acid amide or of the reaction product.
Claim 5
Dependent Claim
20 words
A process according to claim 1 in which the preparation is in the form of an aqueous emulsion or dispersion.
Claim 6
Dependent Claim
37 words
A process according to claim 1 in which the preparation contains, in addition to the acid amide or to the reaction product, 0.01 to 0.05 percent by weight, relative to the dry textile material, of an emulsifier.
Claim 7
Dependent Claim
44 words
A process according to claim 1 in which the preparation contains, in addition to the acid amide or to the reaction product and in addition to the emulsifier, 0 to 0.05 percent by weight, relative to the dry textile material, of a wetting agent.
Claim 8
Dependent Claim
18 words
A process according to claim 1 in which the preparation has a pH value of 4 to 6.
Claim 9
Dependent Claim
25 words
A process according to claim 1 in which the textile material consists of natural or synthetic fibers, or of mixtures of natural and synthetic fibers.
Claim 10
Dependent Claim
18 words

Claim 12
Dependent Claim
30 words
A composition for performing the process according to claim 1, which has a pH value of 4 to 6 which is adjusted to the required value with a weak acid.
Claim 13
Dependent Claim
29 words
A composition for performing the process according to claim 1, which is obtained from a high-pressure emulsion and which at room temperature is in the form of a dispersion.
