The first water repellent agent composition contains amino-modified silicone, a silicone resin, and a polyfunctional isocyanate compound. The second water repellent agent composition comprising dimethylpolysiloxane having a hydroxyl group and/or an alkoxy group having 1 to 3 carbon atoms, an amino group-containing silane coupling agent, a silicone resin, and a polyfunctional isocyanate compound.

A method of preparing a water-repellent and moisture-permeable fabric, includes: preparing a water-repellent fabric by: immersing a raw fabric in a non-fluorinated water-repellent emulsion containing a non-fluorinated water repellent and an aqueous blocked polyisocyanate crosslinking agent; and drying and curing the raw fabric, which has been immersed, at a temperature of 150 C. to 200 C.; applying a polyurethane-based moisture-permeable coating liquid to the water-repellent fabric; and drying the water-repellent fabric while increasing a temperature from 100 C. to 150 C.

The invention relates to copolymers comprising or consisting of, preferably consisting of three components:

component a) having at least one biuret or isocyanurate substructure,
component b) selected from polysiloxanes and polyhydrocarbons, preferably polysiloxanes,
component c) comprising a hydrocarbon which is different from component b) and has at least 6 carbon atoms and not more than 3 heteroatoms selected from the group of N, 0, S,
where component b) is joined to 2 different or identical components a) via at least two positions; and to the preparation and use thereof for finishing of fabrics.
