Leather

LEATHER IS NOT JUST LEATHER

Depending on how the surface was processed after tanning, a distinction is made between natural leathers (aniline leathers), slightly pigmented leather (semi aniline leather) or pigmented qualities (covered leather). Is the surface of aniline leather sanded to a greater or lesser degree it is called leather with nubuck effects or nubuck leather.

Another distinguishing feature is the strength and quality of the leather. Leather is often split over the entire surface. Basic leather begins by a thickness of 0,9 mm - 1,1 mm. Leather with a thickness of 1,4 mm - 1,6 mm is already considered thick leather. Our strongest leather on the other hand takes a full of 5mm thickness and requires special understanding for the material and hand-craft Know-How.

Pure nature - for furniture with characterPURE NATURE - FOR FURNITURE WITH CHARACTER

With natural leather, the so-called aniline leathers, transparent dyes penetrate deep into the hide and color it "from the inside out". No pigments whatoever are applied to the surface of the skin. The pores remain open and all signs of nature and growth remain compeletely visible. The leathers are characterize by a high breathability and its comfort qualities. Aniline leathers give the furniture character, they make the furniture individual and natural. They "share our live" and become more beautiful the older they get. Short: From these leather qualities the highest quality covers are produced.

Aniline leather with nubuck effects or proper nubuck leather remain aniline but are additionally sanded for finishing. This creates a velvety surface, which gives the leather its sympathetic-soft feel and provides the so-called writing effect. The structure of the skin remains visible. The leathers look matt, almost powdery. They are very soft and are characterized by vibrant colors and high breathability.

People who prefer a leather which is more consitent in look and color, often choose a slightly pigmented leather. With this so-called Semi aniline leather the surface of the hide is dyed slightly in addition to the dyed hide itself. Smooth color pigments make the skin texture mor consistend. A part of the pores remains open, the leather can contain wetness and can give it off again. But the pigments make it more insensible and more robust against outside influences. Slightly pigmented leathers have very good comfort and wear properties.

Allrounder -  tough and harmoniousALLROUNDER - TOUGH AND HARMONIOUS

An absolutely uniform surface can only be achieved if a covered, full pigmented leahter is choosen. In addition to the dyeing of the skin, the main surface is completely refined with pigments. The surface loos harmonious. Allthough the breathing capacity is restricted but pigmented leather are particularly insensitive and thus easy to clean and user friendly.



LEATHER IS HOME DECOR

Leather is a natural product and one of the oldest materials with which humans surround themselves. In winter it warms, in summer it cools. It is robust, resilient, pleasantly soft and natural. A great material: smell it, feel it - a unique experience for all the senses! Our leathers are leathers that perfectly combine aesthetics and suitability for everyday use. Only through them do our upholstered furniture become personalities.

EACH SOFA IS UNIQUE

Leather is a natural material, grown, a piece of lived nature. Each hide reflects the life of the cattle, has a different shape and size as well as an individual surface with a multitude of natural features, which are reflected in structure and color due to growth or which are caused by overgrown injuries - life leaves behind over time his tracks. And you can see them.

NATURAL AND GROWTH FEATURES

This already explains an important characteristic that is typical of the goods and determines its appearance: natural and growth features are completely natural components of leather. In fact, it's the naturally occurring features that make leather such a unique material. They are quality indicators that testify to the authenticity of the material, because every skin is different. They allow us to bring a piece of lived nature home. And they give every piece of furniture a very individual touch, making it unique, one of a kind.

COLOR AND STRUCTURE DEVIATIONS

The natural features also include color and structure variances. Due to the natural origin of the material, color and structure deviations are possible and permissible within a single item or within a group. However, we guarantee careful color sorting and selection for the corresponding amount of leather required per commission.

NATURE THAT YOU CAN SEE

The extent to which natural and growth features are visible in the finished leather depends on the quality of the leather. With natural leathers (aniline leather), the surface of the skin is neither changed nor covered. This means that all natural features remain completely visible. In the case of partially covered qualities (semi-aniline leather) or completely covered leathers, an additional layer of pigment is applied to the surface. Under it, existing natural features appear less strongly without being completely lost.

PROCESSING OF NATURAL FEATURES

Natural features as natural components of the leather have no influence on the quality of the leather. Their processing during the upholstery production is therefore not a reason for complaint. However, we make sure that natural features appear evenly in the finished product. The decisive factor for this is the harmonious overall appearance of the furniture: We always use natural features when they are not impaired. Real mistakes, however, which could affect the quality of the leather, are spared when the leather is cut.

FROM SKIN TO LEATHER

Our leather is mainly produced in Italy, because this is where the world's best tanneries are located, but there are also many well-known companies in the south of Germany. They ensure that a by-product of meat production is turned into high-quality second-hand goods. The basis for this is the careful selection of the raw hides, which are refined into leather in highly complex processes over several weeks.

RAW MATERIAL

Depending on the demands on the material to be produced, hides of different races and countries of origin are used. Most of the KOINOR leathers come from well-bred cattle in Europe. These are considered to be of particularly high quality, as the animals often grow up in the barn and are fed appropriately. The best leather qualities can be made from them: as large as possible, with a good skin structure and only a few natural features (fattening folds, scarring, etc.).

Unlike cattle in South America, for example. The animals there live free and are exposed to completely different growth conditions. Therefore, traces of life (scars from cracks in the hedge, insect bites or battle marks, etc.), which appear naturally in the skin and ultimately also in the leather, are much more common and varied.

WATER WORKSHOP

First of all, impurities, meat and hair must be removed from the cowhide using a machine. This is done with a whole series of work steps in the so-called water workshop, in which the raw material is prepared for the actual leather production. Many washing processes in large drums or barrels are characteristic.

With a heavy bull, the skin is still a good 8 mm thick. Because this is too strong for leather and you also want to get leather that is evenly thick, the hides are split over the entire surface.

TANNERY

Only now does the central process of leather production begin: tanning. The animal skins are now permanently preserved through a chemical process. Various tanning substances are introduced into the skin, which leads to a cross-linking of the fibers. The animal skin maintains its resistance to water, temperature and rot. Most leathers are tanned using minerals. However, only chrome tanning is of economic importance. The so-called "wet blue" is produced as an intermediate product after tanning.

Originally, many of the high-quality KOINOR leathers were vegetable tanned with a vegetable raw material: with tanning agents from the South American tara pod. In the meantime, many of our leathers are tanned with mineral metal salts, but the name has remained. “Tara” is and remains the label for high-quality KOINOR leather.

FINISHING

But no ready-to-use product has yet been created. The leather lacks essential properties. It still has to be "trimmed" and further refined in terms of its texture and appearance:

Should the leather be soft or a little firmer? Should it have a special structure? and which color? Should the natural surface be completely preserved or should additional pigments be applied for protection?
