AQUEOUS FINISHING AGENT AND PROCESS FOR A SOFT HAND,WATER AND OIL REPELLENT TREATMENT FOR FIBROUS MATERIALS
The invention describes an aqueous finishing composition for conferring soft water/oil repellancy on fibre materials which is composed of the following components: A) 25 to 65% by weight of a water/oil repellant which contains perfluoroaliphatic groups (at least 5% by weight of fluorine) and is in d...

Zusammenfassung: | The invention describes an aqueous finishing composition for conferring soft water/oil repellancy on fibre materials which is composed of the following components:
A) 25 to 65% by weight of a water/oil repellant which contains perfluoroaliphatic groups (at least 5% by weight of fluorine) and is in dispersion,
B) 10 to 35% by weight of a dispersion of an emulsifiable polyethylene (density at 20 DEG C at least 0.92 g/cm , acid number at least 5) and
C) 25 to 40% by weight of a fluorine-free dispersion of a soft handle extender based on a modified hydrogenalkylpolysiloxane.
There is also claimed a process for conferring soft water/oil repellancy on fibre materials.
Very good oil- and water-repellant effects are achieved which, what is more, are very highly wash- and drycleaning-resistant. Also, the particularly smooth, soft handle is notable. |
