Réseaux neuronaux (informatique)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The leather industry is a traditional manufacturing industry with a long history in China. In recent years, the output of China's leather industry has jumped to the first place in the world, but some problems have appeared in the rapid development.' The most serious one is the ecological environment problem, which has already seriously hindered the healthy and rapid development of China's social economy.
In this paper, we focus on the evaluation of leather ecosystem. The evaluation indexes are set up for the sub-systems of leather's ecological natural system, leather's ecological economic system and leather's ecological social system. The BP neural network optimised by a Bayesian algorithm is introduced to evaluate the leather ecosystem. The grade of leather's ecological status in the last ten years is analysed to find the problems and put forward corresponding suggestions.
The study found that the leather ecosystem had a strong self-regulation ability. Since China is a developing country, the pursuit of economic benefits is more important and urgent than the pursuit of ecological benefits, and it is difficult to realise the ideal state of the leather ecosystem at present.Note de contenu : - A brief introduction to China's leather industry

However, there is a certain subjective element affecting the final result. It would be valuable to set up a scientific theory and find a parameterized objective test method for leather handle character. In this paper, research results were analyzed to determine whether there was a interrelation between the handle character (softness, fullness and elasticity) and mechanical parameters measured at specific technical states.
Softness can be characterized by bending coefficient (Kb) ; fullness can be characterized by compression index (Kc); stretchability by lastometer coefficient (K1) and elasticity by bending stress relaxation attenuation constant (αb) and bending stress attenuation (K). The statistical method of discriminatory two class analysis (DATC) was there adopted to characterize the handle of leather. The corresponding experiment and the application of DATC in the evaluation of leather handle character was carried out and the DATC results were found to be significant at a level greater than 99%. The findings indicate that the DATC method can be regarded as a comprehensive analysis method to, objectively and correctly, characterize the handle of leather.Note de contenu : - Interrelated research : Compressibility of leather - Bending property of leather - Lastometer property of leather

To monitor these reactions, we had added fluorescently labeled proteins to stock solutions and examined the resultant filled leather using a microscope equipped with an epi-fluorescent attachment. In this present study, based on our understanding of the effect that enzyme modification will have on physical properties of crosslinked proteins, we polymerized potential filler products prior to their addition to the wet blue. We characterized the products with respect to their physical properties and molecular weight distribution (degree of polymerization). These products were applied to wet blue and evaluated, again using fluorescent labels to monitor their filling capability. It was shown that the proteins were evenly distributed throughout the hide and, more importantly, were not removed during the washing steps. Micrographs showing the location of fillers using fluorescent labels are presented.

NubuckLe nubuck1 est une croute de daim ou de cuir. Sa particularité vient du fait qu'il a subi un traitement particulier. En effet, sa surface a été meulée ou grattée au papier de verre très fin. C'est pourquoi il revêt cette apparence veloutée et sa douceur au toucher. Le ponçage de la fleur lui donne un aspect qui diffère largement du suède. Comme seule la surface externe du cuir est touchée par le traitement, il possède une meilleure résistance et conserve toute la finesse de son grain.
Il est utilisé particulièrement dans l'industrie de l'ameublement pour la fabrication des fauteuils et canapés ainsi que par l'industrie de la chaussure. Il est souvent assez coûteux, car c'est une matière qui a une certaine noblesse. Son nom provient probablement de la langue anglaise, et de new buck qui signifie nouveau daim.
PhotocatalyseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Titanium dioxide (Ti02) is well known for its photocatalytic capabilities, and its applications coverl different areas, such as wastewater treatment, sunscreen and ultraviolet (UV) blocking, among others. Its application as a photocatalytic additive for self-cleaning properties has been reported with different substrates, resulting in stain degradation. As such, the goal of this work was to functionalise two types of nubuck leather, conferring on them self-cleaning properties. For this purpose, two photocatalytic materials were tested: a commercial TiO2 (Degussa P25 Ti02) and Si02@Ti02 nanoparticles, which were applied onto leather surfaces by a spray coating technique. The hydrophilic behaviour of these two types of nubuck leather was determined by contact angle (CA) measurement, using the sessile drop technique. The finished samples of nubuck leather were characterized by measuring their diffuse reflectance. The self-cleaning properties of finished nubuck leather samples were evaluated through their ability to photodegrade an organic stain, rhodamine-B dye. The P25 TiO2 and Si02@TiO2 particles did not provide self-cleaning properties for the two types of nubuck leather, indicating the need for more in-depth research on the use of these particles for self-cleaning purposes.

Titre : Evaluation of the stability of organic acid-masked aluminum complexes by size exclusion chromatography Type de document : texte imprimé Auteurs : Tingyou Zhang, Auteur ; Eisuke Takata, Auteur ; Kunio Shirai, Auteur Année de publication : 1996 Article en page(s) : p. 95-99 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Citrate, tartrate, and acetate-masked basic aluminum chloride solutions were stored in the acidic medium (pH 2.3 to 4.2) and analyzed for the proportion of polynuclear fractions of complexes by size-exclusion chromatography (SEC). Polynuclear fractions in citrate or tartrate-masked samples decreased clearly with lowering pH and prolong storage as well as with dilution as judged by SEC. In contrast, the polynuclear fractionsin acetate-masked and unmasked basic aluminum chloride indicated a significantly high stability under the same conditions. It is explained in terms of the higher stability of olated complexes that constitute the polynuclear fractions of both samples. The proposed SEC method can serve to evalute the stability of polynuclear fractions of masked aluminum tanning agents in acidic medium.
