| titleOfInvention | Method for the hydrofugation of hides and skins |
| abstract | Method for the waterproofing of hides and skins characterized in that the skin or leather is treated, before, during or after retanning, with one or more formulations containing from 1 to 30% by weight, based on the formulation, of a mixture of polysiloxanes containing from 10 to 90% by weight, based on the mixture, of one or more polysiloxanes containing carboxyl groups, from 90 to 10% by weight, based on the mixture, of one or plus polysiloxanes free of carboxyl groups, and from 3 to 25% by weight, based on the formulation, of at least one emulsifier, where the polysiloxanes containing carboxyl groups are those polysiloxanes that contain the structural elements of formula I, II and optionally IIIa and IIIb ** Formula ** in which the variables are defined as follows: R1 is hydrogen, hydroxyl, C1-C4 alkyl, C6-C14 aryl, C1-C4 alkoxy, amino, mono-C1-C4 alkyl- same or different amino, dialkyl-C1-C4-amino or Z1-A1-COOH and independently one of l other; A1 are the same or different C5-C25 alkyls and linear or branched, Z1 is a direct bond, oxygen or an amino, carbonyl, amido or ester group and in which the carboxyl group-free polysiloxane (s) are linear or cyclic or branched and are composed of structural elements of formula I and optionally IIIa, IIIb and / or IVa, ** Formula ** where R1 is hydrogen, hydroxyl, C1-C4 alkyl, aryl-C6-C14, identical or different C1-C4 alkoxy and independently one from the other, where - the linear polysiloxanes free of carboxyl groups consist of structural elements of formula I, IIIa and / or IIIb, - the cyclic polysiloxanes free of carboxyl groups consist of structural elements of formula I, - the branched polysiloxanes free of groups carboxyl consist of structural elements of formula I, IVa, IIIa and / or IIIb. |
