The gap between aniline leather and semianiline leather
Pure aniline leather may not have a pigmented surface according to the definition of this type of leather. Even minimal pigmentation is not permitted. Therefore, aniline leather is susceptible to stains. As soon as a pigmentation takes place, the leather is no longer an aniline leather. If the leather is only minimally pigmented so that the leather remains as natural as possible, the leather does not meet the minimum requirements for the leather type semianiline leather. Between aniline leather and semianil leather, there was so far no standardized leather.
Aniline leather are not allowed to have a pigment coating.
This conflict occurs mostly in upholstery leathers. On one hand, the leather furniture manufacturers want the best leather quality (aniline leather), but on the other hand, the aniline leather should not fade, should not have natural markings on leather and as few color deviations as possible and should not be susceptible to stains.
In aniline leather liquid penetrates immediately. A light finish improves protection.
To solve this dilemma, some tanneries have applied thin layers of pigment onto the leather. This was intended to be as close as possible to the aniline leather, but nevertheless to apply a light protection in order to meet the legitimate wishes of the furniture trade and the end users. If pigments were found on the surface during investigations, the accusation arose, that no high quality aniline leather had been sold. If it was then tested for semianil leather, it did not meet the minimum requirements for light fastness or friction resistance.
This regulatory gap gave the impression that the tannery had produced a deficient leather. But a leather between aniline leather and semianil leather is an excellent leather of excellent quality. It is coated as little as possible to preserve the naturalness. It has a minimum protection which is better than with completely porous aniline leather. It does not fade so easily and is not so stain-sensitive.
For the consumer its not understandable that pure aniline leather, which is located in the highest price class, fades in the course of time and that normal stains are difficult to be cleaned. Thus, slightly pigmented leather between aniline leather and semianil leather is an enrichment and a positive development for the leather manufacturers, leather traders, furniture manufacturers and the final consumers.
Aniline leather, refined – Refined aniline leather
At the beginning of 2016, the term "aniline leather, refined" appeared for the first time in the new formulation of RAL 430/4. According to the definition there, a refined aniline leather must have almost completely visible hair pore. A applied pigment coating is not allowed to exceed 0.015 mm. In the case of aniline leather, a pigment-free coating should not be above 0.01 mm.
In RAL 061 A1 (March 2016) the rules were tightened once more. Accordingly, the pigmentation is not allowed to exceed 0.01 mm. The natural hair pores must remain clearly visible, the hair pore channels are not allowed to becompletely filled.
Presumably the "aniline leather is refined" will overtake the pure aniline leather in the furniture sector. The tendency to the patina formation of the high-price pure aniline leather only makes sense for buyers who want exactly this property.
Although the distinctiveness of the types of leather does not get easier for consumers and experts by this new kind of leather, the manufacturers should adhere to the new definitions in the declarations of the leather. This solution is the right way to offer the end users the best smooth leather in the high price segment. It will certainly take a few years until the new term "aniline leather refined" has become established.
The following exsamples of pore recognizability are only indicative. Depending on the leather batch and area of the skin, large fluctuations of the pore visibility can already be present within one skin.
Reinanilinleder ist komplett offenporig ohne Pigmentzurichtung.
Anilinleder veredelt hat nur eine ganz dünne Pigmentzurichtung auf der Oberfläche, die kaum auffällt.
Bei Semianilinledern ist das Porenbild noch gut erkennbar, aber nicht mehr nahezu vollständig.
Ist das Porenbild kaum noch erkennbar, handelt es sich um pigmentiertes Glattleder.
