Sanding leather - Buffing leather
When sanding leather, the leather surface ([Leather grain - Grain side|grain side]]) or back side (flesh side) is sanded by means of abrasive paper on a rotating roller. This results in a uniform suface. In the earlier times of leather production, such work was purely manual work.
When sanding the grain side, you get a light velvet-like pile. The leather is then called nubuck.
If a smooth leather is sanded for smoothing the surface, the tanner also calls this buffing. Buffing is also called the flat sanding of scars in the leather. That result is a nubuck.
Nubuck
Nubuck is made by sanding rough (buffing) the grain side.
Corrected grain
Sometimes, buffing is carried out before applying a binder-based pimgent colour layer and embossing the leather. The result is then a corrected grain. The reasons are to make skin damages invisible and also the desire to obtain a uniform grain pattern in order to reduce the cutting waste. Such leather does not belong to the superior quality, because the finish and the embossing reduces softness and naturalness. Aniline leather and semi-aniline leather are not buffed and are rarely embossed and are therefore higher quality and more beautiful leather.
There are also leathers, which are only slightly buffed and emboosed and [Haptic evaluation of leather surfaces|feel beautifully soft and warm]]. But this is an exception.
[[Corrected grain|Buffed and embossed leather]]. The hair pores are removed by buffing and embossing.
Um zu prüfen, ob unter einer Farbschicht geschliffen wurde, muss diese mit einem Lösungsmittel entfernt werden. Kommt eine nubukartige Oberfläche zum Vorschein, ist das Leder vor der Färbung angeschliffen worden.
Unter der Farbschicht kommt eine leicht aufgeraute Oberfläche zum Vorschein. Hier wurde geschliffen.
Unter der Farbschicht kommt eine stark aufgeraute Oberfläche zum Vorschein. Es handelt sich um beschichtetes Spaltleder.
