Propriété intellectuelle (droit international)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Intellectual property rights have become one of the most important components to enhance China's international competitiveness and image and have increasingly become an academic hot spot. However, most of the studies are focusing on the areas including the improvements of law and the construction of protection systems. Based on a search of existing domestic and global literature, this paper used the Cobb-Douglas production function to establish a model for the development of leather industry in China, which has calculated the output coefficients of fixed capital input, labour input and intellectual property input in the leather industry, and the Solow Remainder Value Method has been further used to calculate the contribution rate of intellectual property input to the economic growth of the leather industry in China. The above calculated results show that investment in intellectual property contributes significantly to the growth of China's leather industry economy. This paper also contributes by proposing a new path for the transformation and upgrading of China's leather industry, which will be driven further under the background of intellectual property innovation.

PerméabilitéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Based on the grey system theory, this paper analyzes the comprehensive influence of the quality parameters of sheep leather on the moisture permeability of different parts of sheep leather. The differences in specific surface area and average pore size of sheepskin in different parts were analyzed, and the grey correlation analysis between the three influencing parameters and the moisture permeability of sheepskin in different parts was carried out. The study found that the specific surface area and average pore size of sheep skin in different parts were different. The specific surface area of sheep skin in different parts was ranked as follows: belly > back > neck > hip, and the average pore size was ranked as follows: neck > back > belly > hip. Through the comprehensive analysis of grey correlation, it is found that the order of influence of quality parameters on the moisture permeability of natural sheepskin is: average pore size > thickness > specific surface area.

Peau -- HistologieIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Most people around the world regard mink skin as luxurious commodities, since the mink hair is generous and guard hair length is moderate. However, a variety of reasons will attribute to hair loss or orientation phenomenon of upper hair in the processes. The paper studied the processing histology of mink in the processing, which could build a scientific foundation to optimize the process, improve the technical skills and improve product quality. Mink skin samples used in the experiment were taken from soaking, degreasing, bating, pickling, and tanning processes. The photomicrographs were observed by bio-optical microscope. Besides, samples were performed by frozen section method and stained with iron hematoxylin staining method as well as Gill modified hematoxylin staining method. It is found that the hair follicles of the mink were distributed irregularly in the form of compound hair follicles or individual hair follicles. Mink fat glands were very developed. In other words, each hair follicle generally was surrounded by a pair of fat glands. With the increase in degreasing time, the number of fat cells in the fat glands was reduced and the fibers around the hair follicles were initially dispersed. The voids between the collagen fibers became larger and more fully loose after the processes of bating and pickling. In addition, the collagen fiber wove more orderly and closer by tanning. In the case of pickling and bating, most of the hair follicle openings were opened, which could abate the chained force between hair and the follicles and/or the dermal papilla.

Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : A highly expeditious method for the direct analytical control of leather fat as an alternative to the officially endorsed methods was developed based on solvent extraction. The proposed method uses multivariate calibration with partial least-squares regression (PLSR) of diffuse reflectance spectra (NIRRS) for leather specimens. The reference values of the calibration matrix are used to derive those for powdered leather extracted with methylene chloride using the official method. Two different approaches based on matrices containing spectral information for powdered leather and spectra directly recorded on unpowdered leather samples were developed.
The optimum calibration model for powdered samples is based on the second spectral derivative and 3 PLS components, and provides overall relative calibration and prediction errors in the region of 5%. On the other hand, the optimum prediction model uses the first spectral derivative and 5 PLS components; the results are similarly as good as those of the calibration model, but the prediction of some external samples results in larger errors arising from the inability to construct calibration sets encompassing the whole variability of the prediction set.
Fibre optic-based NIR spectroscopy in combination with multivariate calibration appears to be an effective alternative to existing methods for the analysis and control of fat in the leather tanning industry as it is a rapid method and uses no reagents.Note de contenu : - EXPERIMENTAL PROCEDURES : Leather and fat-liquoring - Samples - Apparatus and software - Recording of NIR spectra - Processing of data
