“…In addition, durability limit increases by 13.0%, the yield of thickness -by 4.2%, vapour permeability by 2.0 times, the yield of area by 1.5%, grade of quality by 0.5 %. Furthermore, as a result of decreasing the tanning process length by 2.5 times and decreasing the chrome compounds content in discharged chrome-containing solutions by 2.0 times, as well of lowering the content of sulphates by 1.5 times, chlorides by 1.2 times, BOD 5 by 2.0 times, COD by 1.2 times the ecological and energetical load on the environment also goes down [34].…”

A UNIFIED TECHNOLOGY OF CRUST LEATHER PRODUCTION USING POLYMERIC COMPOUNDS DEVELOPMENT ABSTRACT. Nowadays there is a considerable deficit of extractive, material and energy resources. Thus, there is a topical issue of creating, developing and application of ecologically friendly, resource-saving technologies of natural leather development, using modern materials, which are able both to replace toxic reactive chemicals, fully or partially, and maintain the high quality of products. We have developed a standardized technology of crust leather production regarding the tanning and crusting processes, using ecologically friendly polymeric compounds of the new generation. This technology provides a more sustainable use of leather raw materials and chemicals, decreasing the processing length and environmental harm. KEY WORDS: crust leather, standardized technology, tanning, crusting processes, polymeric compounds O TEHNOLOGIE UNIFICATĂ DE FABRICARE A PIELII CRUST UTILIZÂND DEZVOLTAREA COMPUŞILOR POLIMERICI REZUMAT. În prezent, există un deficit considerabil de resurse extractive, materiale şi energetice. Astfel, există o problemă de actualitate privind crearea, dezvoltarea şi aplicarea tehnologiilor ecologice, care să ducă la economisirea resurselor pentru fabricarea pielii naturale, folosind materiale moderne, care sunt capabile să înlocuiască integral sau parţial substanţele chimice reactive toxice şi să menţină calitatea ridicată a produselor. S-a dezvoltat o tehnologie standardizată de producţie a pielii crust cu privire la procesele de tăbăcire şi prelucrare a pielii în stadiul crust, folosind compuşi polimeri ecologici din noua generaţie. Această tehnologie oferă o utilizare mai durabilă a materiilor prime şi a substanţelor chimice în prelucrarea pielii, reducând durata prelucrării şi prejudiciul adus mediului. CUVINTE CHEIE: piele crust, tehnologie standardizată, tăbăcire, procese de prelucrare a pielii crust, compuşi polimerici LE DÉVELOPPEMENT DE LA TECHNOLOGIE UNIFIÉE DE LA PRODUCTION DU CUIR EN CROÛTE EN UTILISANT DES COMPOSÉS POLYMÈRES RÉSUMÉ. Il existe actuellement un déficit considérable de ressources extractives, matérielles et énergétiques. Ainsi, il y a un problème actuel concernant la création, le développement et l'application de technologies de développement du cuir naturel respectueuses de l'environnement et de l'économie, utilisant des matériaux modernes et capables de remplacer totalement ou partiellement les produits chimiques toxiques et réactifs, et de maintenir la haute qualité des produits. Nous avons développé une technologie standardisée de production de cuir en croûte en ce qui concerne les étapes de tannage et de finissage liquide, en utilisant des composés polymères écologiques de la nouvelle génération. Cette technologie permet une utilisation plus durable des matières premières et des produits chimiques pour le cuir, réduisant ainsi la durée de traitement et les dommages environnementaux. MOTS CLÉS : cuir en croûte, technologie unifiée, tannage, finissage liquide, composés polymères

“…The approach proposed in [5][6][7][8] to solve the optimization problem is associated with the complexity of the formalization and requires a significant amount of calculations. In papers [10,11] it is shown that in some cases the wrong selection of driving directions to the optimum does not lead to the desired result.…”

The article is devoted to the investigation of the efficiency of chromium-modified montmorillonite dispersions to stabilize the collagen structure of the dermis. The interaction of modified dispersions of montmorillonite with collagen of the dermis was studied with the use of IR spectroscopic studies method. The high level of absorption of chromium compounds and their reduction by 30 % in the exhaust fluid was found. The use of montmorillonite dispersions provides qualitative formation of the structure of the dermis and physical and mechanical properties, with a reduction of tanning agents’ costs/waste by 16 %.
