physical tests on leather

Chemical analysis of leather is essential to check for the presence of potentially harmful substances such as chromium VI, formaldehyde, azo dyes, and heavy metals. These tests guarantee the safety of materials and compliance with international regulations, such as REACH regulations and ecological standards for products intended to come into contact with human skin. The analyses are performed using advanced instruments, such as spectrometers and chromatographs, capable of detecting even the smallest traces of prohibited substances. This service is particularly sought after in the high fashion, luxury, and furniture sectors.

Color fastness is an essential aspect for ensuring the aesthetic quality of leather over time. This test verifies the resistance of the dye to various factors such as rubbing, sweat, sunlight, and chemical agents. Using specialized machines, the leather is subjected to rubbing tests with specific materials, prolonged exposure to UV rays, and contact with synthetic substances to simulate degradation due to daily use. The results allow us to determine color stability and prevent unwanted discoloration in sectors such as fashion, automotive, and furniture. The most requested tests are Martindale, Bally, Flexometer, Xenotest, climatic chamber, perspiration, and tensile testing.

In addition to testing skin samples, it is essential to check the quality of the finished product. We carry out customized analyses and tests on footwear, clothing, leather goods, and accessories. This analysis assesses the mechanical strength, durability, and reliability of assembled leather goods, such as bags, belts, seats, footwear, fashion accessories, uppers, eyewear, watches, heels, linings, insoles, soles, heel tips, laces, zippers, and small parts. Tests may include seam tensile tests, resistance to mechanical stress, and simulations of prolonged use, with the aim of ensuring that the final product meets the required standards in terms of quality, comfort, and performance, and avoiding defects that could compromise its durability.

The definition of technical specifications is a fundamental step in ensuring consistent leather quality throughout the production chain. This service involves the drafting of detailed technical specifications, customized according to customer requirements and the final application of the material. A risk analysis approach also helps to assess the analyses that are actually necessary, reducing time and costs. The drafting of technical specifications is particularly useful for brands and manufacturers who wish to ensure high standards of performance and compliance with current regulations.
