“…In recent years, a large number of studies have focused on the implementation of environmentally-oriented technologies, aimed at the use of the compositions based on bentonite clays for the production of leather for different purposes. According to the results of the presented studies [2], this is caused by the special colloid-chemical properties of the basic mineral of bentonite clays -montmorillonite. Thus, research [3] proved the enhancement of physical-mechanical indicators of finished leather, improvement of state of waste water of leather producing enterprises and improvement of ecological safety of production, indicating the prospects of the application of montmorillonite and compositions on its basis for treatment of skins.…”

lization of the capillary-porous structure with the required level of hygienic properties. An innovative direction of effective tanning of leather is the use of tanning compositions based on montmorillonite dispersions [1]. This contributes to the complex formation of the structure of derma via formation of bonds not only between collagen and tanning compound, but also between the mineral, tanning compound and collagen. To enhance the effectiveness of the above-mentioned method of tanning, it is important to establish and identify chemical interactions both for the modified mineral, and for derma collagen after treatment with obtained tannic compositions. Accordingly, it is necessary to consider that research, aimed at the application of modified montmorillonite dis

“…We should mention that synthesis and industrial implementation of new types of dyes mean considerable money, time and material investment. For this reason researches (Haroun and Mansour, 2008;Danylkovych et al, 2016) are being done, dealing with the use of chemicals which can influence the colour and aesthetic qualities of finished leather positively without damaging its consumer properties in liquid finishing processes. To understand the interaction between collagen of derma, materials used and dyes better various analytical methods are used, such as the method of Fourier infrared spectroscopy (Sudha et al, 2016;Pellegrini et al, 2015;Campos Vidal and Mello, 2011;Sukhodub et al, 2004;Kanagaraj et al, 2015).…”

Nowadays, leather industry is suffering from low quality of raw materials, usage of efficient and environment unfriendly materials. This situation may be corrected by upgrading the existing or developing new technologies using efficient chemical materials, such as polymeric compounds. The aim of the study was to improve the leather dyeing processes through usage of water-soluble polymers derivatives of acrylic and maleic acids in the direction of simplification and reduction of processing materials consumption, ensuring high product quality, establishing the mechanism of interaction between these materials and collagen. The reactions in the "collagen-polymeric compounds-dye" system were studied using IR-spectroscopy. The fiber preparation from the untanned leather industry waste was used for the collagen prototype. The data obtained show correlation between interaction type in the system under study as well as leather properties and processing conditions. We have established a positive effect of investigated polymers on the physical, mechanical, and hygienic leather properties. It can be explained through their ability to be absorbed on the surface of the derma structural elements; to interact with them and other applied reagents (tannins, dyes etc.), there by promoting structure formation and improving product quality.
