| Abstract: | The mechanism of water vapour permeability of the coagulated PU leather is deacribed. The water absorptivity and water vapour permeability of semi-finished coagulated PU leathers were measured. The paper discusses the effects of water absorptivity of the fabric, the structure,density and thickness of the PU film, and cellulose filler, surface printing, transfer coating and embossing processes on water vapour permeability of coagulated PU leather. And the auther gives some suggestions to improve water vapour permeability. |
