Skin Types Most Requested
The skins used for the car interior come mainly from cattle, preferably large, to efficiently cover extended surfaces such as seats, dashboards and door panels. The most requested types are:
* Tassel: Often synonymous with high-end leather in the automotive world, nappa is a full-grain or semi-aniline skin extremely soft and smooth to the touch. Its delicate workmanship preserves its natural grain, offering a tactile and visual experience of pure luxury. It is used for seats, steering wheels and details that require refined elegance.
* Pigmented Leather (or Correct Flower): Essential for its resistance, it is the most common type in automotive. Its surface is treated with pigments and a protective finish that makes it extremely resistant to wear, abrasions, stains, thermal changes and UV rays. While being less soft than tassel, it guarantees a long service life and easy maintenance, making it ideal for intensive daily use.
* Frosted Skin: Sometimes used to create particular aesthetic effects, this skin has a slightly smooth surface for a uniform appearance. It is then pigmented to increase the resistance.
Automotive Specific Processing
Automotive leathers must pass a series of rigorous workmanship and testing to meet the high standards of the industry:
* Tanning: Most car skins are chrome tanned, a process that gives robustness, flexibility and excellent heat and moisture resistance, critical factors in the interior environment of a car.
* Finishing: The leathers are treated with protective finishes (often based on polyurethane) to make them resistant to rubbing, stains and fading. These processes are crucial for safety, as the skins must comply with flame-resistant standards and must not release odors or harmful substances ("fogging").
* Craftsmanship: Despite the need for large-scale production, the luxury market is looking for craftsmanship. The skins can be perforated, quilted or embellished with contrast stitching and embroidered logos, to create custom details that make each vehicle unique.
Quality Required by the Market and Interior Designers
Car interior designers require leathers that are a perfect balance between beauty and functionality:
* Durability and Resistance: The skin must withstand continuous use and extreme environmental conditions, including temperature changes and prolonged exposure to sunlight.
* Uniformity and Coherence: It is essential that the supply offers a uniformity of color and thickness over the entire surface, to avoid visual defects in the finished product.
* Hand and Touch: Feeling to the touch is a luxury factor. The skin must be soft, pleasant and "warm", conveying a sense of superior quality.
* Sustainability: There is a growing demand for leathers that come from sustainable tanning and finishing processes, certified by bodies such as the Leather Working Group (LWG).
* Technical Performance: The leather must pass specific sector tests for tensile strength, abrasion, color strength and "fogging", ensuring maximum safety and reliability.
