Abstract

Disclosed is a fiber binding powder composition for consolidating fiber materials, comprisinga) a polymer powder based on a polyvinyl alcohol stabilized polymer of one or more monomers selected from the group consisting of the vinyl esters of branched or unbranched carboxylic acids having 1 to 12 carbon atoms, the esters of acrylic acid and methacrylic acid with branched or unbranched alcohols having 1 to 12 carbon atoms, aromatic vinyl compounds, vinyl halides, olefins and dienes, andb) an inorganic compound which is solid at room temperature and which enters a chemical bond with the OH groups of the polyvinyl alcohol on introduction of said powder into water.
