Recently, There has been increased requirement to high performance leather for the change of life-pattern. By the trends, high performance leather which has launder-ability, water permeability, and environmental friendship introduced and has been attracted interest in market. A lot of solvent are used to make synthetic leather, e.g. DMF, 2-butanone(MEK), toluene, and they were confirmed as cancer caused or suspicious chemical by clinical researcher. However, physical properties solvent based polyurethane are very excellent, evaporated a lot of corrosive gas included DMF, 2-butanone, toluene during leather manufacturing In this study, water-bone polyurethane with high performance developed to overcome these problem, and develop environmental friendly synthetic leather made of them. We will try to not only develop the foaming technology of water-bone PU but also study manufacturing technology of synthetic leather. |
