VERFAHREN ZUR HERSTELLUNG VON TEPPICHEN MIT POLYURETHAN-RÜCKENBESCHICHTUNG AUS POLYURETHANLATEX

摘要

The present invention is a polyurethane backed carpet having a backing prepared by application of an aqueous dispersion of a polyurethane or a polyurethane-forming material to the back of a carpet substrate. The present invention can eliminate the need to prepare a polyurethane backing from its monomeric components at the carpet manufacturing site. The polyurethane backed carpet of the present invention can be efficiently prepared by a continuous process.
