Abstract
A process for treating a polypropylene textile comprises treating the polypropylene textile with an emulsifier-free aqueous formulation comprising (a) at least one silicone compound having at least one hydrophilic group or (b) at least one ethylene copolymer obtainable by copolymerization of ethylene with at least one ethylenically unsaturated mono- or dicarboxylic acid or anhydride.

A process for treating a polypropylene textile, which comprises treating the polypropylene textile with an emulsifier-free aqueous formulation comprising
- (a) at least one silicone compound obtainable by the reaction of a silicone compound having at least one NH group or at least one C—OH group with at least one aliphatic, cycloaliphatic or aromatic diisocyanate, or
- (b) at least one ethylene copolymer obtainable by the copolymerization of ethylene with at least one ethylenically unsaturated mono- or dicarboxylic acid or anhydride.
An aqueous formulation comprising
- (a) at least one silicone compound obtainable by the reaction of a silicone compound having at least one NH group or at least one C—OH group with at least one aliphatic, cycloaliphatic or aromatic diisocyanate, or
- (b) at least one ethylene copolymer having a melt flow rate (MFR) in the range from 1 to 500 g/10 minutes, measured at 160° C. and under a load of 325 g in accordance with German standard specification DIN 53735, said at least one ethylene copolymer being obtainable by the copolymerization of ethylene with at least one ethylenically unsaturated mono- or dicarboxylic acid or anhydride.
