Process for finishing leather |
摘要 |
In the finishing of leather by spray application in an electrostatic field it is possible to use highly concentrated solutions if these solutions are sprayed into a solvent atmosphere in the presence of inert gases. The finishing process utilizes a solvent atmosphere which has a solvent content of 15-90% of the saturation concentration and a residual oxygen content of less than 10% by volume. The finishes contained are immediately stackable. By working with concentrated solutions it is possible to recycle the solvent from the waste air in an economically acceptable manner.
