In the present work an application of fuzzy neural networks for leather quality determination is investigated. An overview of the surface defects characteristics and their significance has been made. For leather quality estimation the most important features are the size and the location of the defects. These characteristics are measured using image analysis and they are used by fuzzy neural ne...

It is easy to visually distinguish a ceramic knife from one made of steel, a leather jacket from one made of denim, and a plush toy from one made of plastic. Most studies of material appearance have focused on the estimation of specific material properties such as albedo or surface gloss, and as a consequence, almost nothing is known about how we recognize material categories like leather or pl...

In the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. Initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. Then the pigmented samples were scanned, and the values of RGB of images were calculated. The artificial neural network (ANN) method used to make relation between RGB va...

Leather industry is the most important traditional industry to provide the leather products in the world for thousand years. The fierce global competitive environment and common awareness of global carbon reduction make livestock supply quantities falling, salt and wet blue leather material reduces and the price skyrockets significantly. Exchange rate fluctuation led sales revenue decreasing wh...

Yeso sika deer is one of the red deer species inhabited Hokkaido and exhibits seasonal molt twice a year. We investigated seasonal variations of morphological and biochemical characteristics of yeso sika deer skin as well as physical, chemical and morphological properties of its vegetable tanned leather. Morphologically, in spring and autumn, which is just active phase of molting cycle, yeso si...

Raw hides and skin are preserved before processed into leather. Salt preservation is the general and age old popular practice. Possibilities of using other methods of preservations have been analysed in order to reduce the pollution load in the soaking process of leather by many scientist. However, in the present study less salt preserving systems based on herbal extract have been investigated ...

Antimicrobial coating is of great important in leather finishing. Herein, we report a newly synthesized polyurethane with zwitterionic sulfobetaine side groups and evaluate their performance in the antifouling leather coatings. The microstructure of the synthesized zwitterionic polyurethane (iNPU) films has been examined by Fourier transform infrared (FTIR), X-ray diffraction (XRD) and atomic f...

The binding of chlorosulphonated paraffins to collagen triple helices is studied by means of classical molecular dynamics simulations and experimental spectroscopic techniques in order to disclose the principal characteristics of their interaction during the leather fattening process. Indeed, collagen is the main target to develop new leather modifying agents with specific characteristics, and ...

Ecological pressures on chromium have now forced the leather industry to look for possible alternatives. A vegetablealuminum combination tannage has been studied, with special attention being given to intended final product. Aluminum is mineral tanning agents that are widely used to stabilize collagens in the leather industry. In this study, the crosslinking of vegetable and aluminum, with coll...
