Pigmented & Corrected Grain Leather
Pigmented leather (also called corrected grain leather) is characterized by a finishing containing fine particles of pigment in suspension that cover the surface. The result is a leather with uniform surface, excellent light fastness, resistance to liquids, stains and scratches, good coverage of defects and easy maintenance.
"Pigmented" or "corrected grain" leather: What is it and what are the differences with aniline leather?
Pigmented leather, also called corrected grain leather, is a leather whose surface has been covered with very fine particles of suspended pigments that give it a uniform appearance. Pigmented leather is one of the most used leathers kinds and differs from leather tanned and finished with pure aniline, especially in the final aspect. Aniline, as we know, evens the surface and the color that comes out of the bath dye, but does not eliminate absolutely any imperfection or defect present on the vast majority of leathers sent for production; for this reason it exists the corrected grain leather. Each leather has unique characteristics and defects that can vary with respect to different factors. We do not want to dwell here on the origin and nature of these defects: let's just say that very often the pure aniline finishing accentuates the natural defects rather than limiting them. It is therefore necessary to use some sort of trick, in particular with the use of pigments, it is possible to mask defects more or less heavily; from this process also derives the distinction between aniline, semi-aniline and pigmented leather. The more massively the pigments are given, the more the skin moves away from the pure aniline finish and becomes precisely pigmented. With pigmented leather, part of the naturalness is lost but a great uniformity of the leather is obtained at a much more accessible price. The techniques of processing leather of this type, also called corrected grain, have now reached a level of such refinement that they often give a very pleasant appearance and above all, are appreciated by the market.
Corrected Grain Leather
To eliminate the presence of the defects, the leather can undergo a prominent removal (grinding) or lighter one (sanding) of its surface layer called grain side. The leather can therefore no longer be defined as full grain but as a corrected grain leather. A light sanding also gives rise to the nubuck leather, which has a pleasant writing effect and which is not covered by pigments or prints, but in this case the starting leather must be of excellent quality in order not to show signs or defects in the event of wants to make nubuck. After that the grain has been partially removed and then uniformed, the skin is heavily covered with layers of pigments and / or prints of various types in order to create the desired item. This type of processing as well as being used on poor quality leather to recover its appearance can also be performed on good raw hides on which a particular fashion effect is desired.
Vegetable Tanned Corrected Grain Leather
A veg tan skin with corrected grain is nothing but a leather, vegetable tanned instead of chrome, which has undergone treatments that are similar to those just described. Vegetable leather usually lends itself less to becoming a corrected grain leather as its main characteristic is to show the naturalness of the grain regardless of whether or not there are any flaws on the surface; indeed, they are usually the natural signs that characterize a vegetable tanned leather.
