Résumé : |
The trend to produce more aniline leathers even from inferior rawstock has existed for years and is still continuing. In the meantime, all types of leather ranging from shoe-upper leather through fancy leather to upholstery leather are involved in this trend. Since coverage of grain damage by finishing is possible to only a limited extent for aniline leathers, the levelness of aniline dyeings has become even more important. The uniformity from skin to skin within a batch of leather to be dyed is of equal importance.
Even if the same processing procedure and the same chemicals are used, differences in depth and levelness of shade may often occur from drum to drum.
The question now arises as to which factors are responsible for these variations. In our investigations into this matter, we have concerned ourselves with the influence of the wetblues on aniline dyeings. We studied the influence of wetblues under varying conditions by changing the important parameters to such an extent as may occur in daily practice.
The five parameters that were varied consisted of temperature an pH value of the chrome liquors as well as storage time, water content and shaved thickness of the wetblues. |
