PROCESS FOR PRODUCING ARTIFICIAL LEATHER |
摘要 |
<p>Artificial leather is produced by applying a dope comprising urethane prepolymers containing terminal isocyanate groups, an amine catalyst and a foam stabilizer onto a releasing carrier sheet, exposing the resulting coating layer to a moisture-containing gas under controlled conditions, laminating the coating layer onto a backing material and stripping off the releasing carrier sheet. The resulting artificial leather has a cellular structure of polyurethane microfoam in adhesion with the backing material and an adhesion strength of 100 to 10,000 g/cm of width.</p> |
