“…The physical properties of leather change depending on the animal type and the animal individually. Furthermore, these properties exhibit variations in different parts over the leather area (Mutlu et al, 2014). Thus, sampling is important for all leather test methods.…”

Fabrics, leathers and artificial materials show structurally different properties. For example, if a fabric material is woven, it is formed by connecting the threads at a right angle to each other with a certain system; on the other hand, leather is formed by naturally binding complex collagen fibers with specific and different angles depending on their area. Also, artificial materials are produced disparately using PVC and PU. These structural differences directly affect the mechanical properties of materials and therefore Turkish Standards Institute (TSE) offers different test methods for textile and leather materials. There are some differences between these standards according to the shape/size of test samples, jaw length, speed, etc. Since leather is an expensive material and has a limited area, sample sizes of leather standards are smaller than the dimensions specified in the textile standard; however, sample sizes in textile standards can be a problem for some expensive textile materials e.g., silk, silver-added fabrics, vicuna, etc. The aim of this study is to examine the differences between the results obtained from the textile and leather standard methods. In this scope, the tensile strength, elongation and tear load values of the two different tanned garment leathers, artificial material, and two different kinds of woven fabrics were obtained by applying both leather and textile standard methods. While there was a statistical difference between the two methods in tensile strength and elongation values for all materials, no difference was observed in tear load values.

“…Distinctive qualities of sheepskin are: relatively low thickness and friability of leather tissue, its unevenness in topographic areas, which results in low strength, unsatisfactory elastic-plastic and cutting out properties of leather goods. Thus, when improving the existing technical processes or developing new ones we must consider how to solve these problems [3,4].…”

In natural leather production polymeric compounds are generally used during leather finishing coating. However, given that liquid processing is crucial for derma structure and properties development, we have identified the rationale for applying polymers based on maleic and acrylic acids during chrome and titanium tanning of garment leather by analysing specimens of polymer-mineral tanning. We have applied analysis techniques traditional for leather industry (strength of surface, strength and percentage extension, shrinkage temperature, moisture content, mineral substances content etc.), as well as mathematical statistics techniques, in order to do it. It has been established that structure and custom properties development of polymer-mineral tanning leather products has been improved as compared with pickle-chrome tanning ones.
