ABSTRACT:
A full-grained milled napa leather is provided on its grain side with a dressing formed from a solidified plastics dispersion. Required leather properties are still ensured and the production process is substantially simplified and more economical. First, the leather, such as cowhide, is subjected on a mechanically untreated grain side to a milling process for at least two hours. This results in a typical napa structure with a natural pebbled grain. Then, a polyurethane dispersion is applied to the grain side containing pigment particles and optionally further additives. Then the hide is allowed to dry. The solidified dispersion forming the dressing has a thickness of, preferably, from 0.05 mm to 0.07 mm.
