摘要：
An aqueous finishing agent for providing fibrous materials with a soft water and oil repellent treatment is provided. The finishing agent comprisesA) 25 to 65% by weight of a perfluoroaliphatic group-bearing water/oil-repellent agent (at least 5% by weight fluorine) in dispersion,B) 10 to 35% by weight of a dispersion of an emulsifiable polyethylene (density at 20.degree. C. at least 0.92 g/cm.sup.3, acid number at least 5) andC) 25 to 40% by weight of a fluorine-free dispersion of a soft-hand extender based on a modified hydrogen alkyl polysiloxane. A process for providing fibrous materials with a soft water and oil repellent treatment is also provided. The finishing agent provides fibrous material with excellent properties which are resistant to washing and dry cleaning and a particularly smooth, soft hand.
