COMPOSITION FOR IMPROVING WETTABILITY OF SURFACES

摘要

The invention is directed to a method for improving the wettability/hydrophilicity of hydrophobic substrates by applying block copolymers to said substrates wherein the block copolymers comprise a quaternary ammonium polymer block and a hydrophobic block. The method of the invention is especially advantageous when used to improve the wettability of nonwovens and in the treatment of hydrophobic surfaces encountered in the home to prevent the buildup of soil residues.
