Abstract (English):
This work solves the problem of choosing an intensifier for the sorption of silver ions by textile materials made from natural fibers to obtain medical products as a result. The conducted studies were aimed at studying the process of sorption of silver ions (Ag+) by natural textile materials, such as cellulose (linen, cotton) and wool fibers. The purpose of the study was to identify the patterns and features of this process, taking into account the chemical structure and structural organization of materials. In addition, an important task was to determine the conditions under which the maximum sorption capacity of fibers with respect to silver ions can be achieved. One of the key aspects of the study was the analysis of the kinetics of sorption of silver ions by various textile materials. To increase the sorption activity of these materials, they were modified with synthetic polyelectrolytes. Among the polyelectrolytes used were polydiallyldimethylammonium chloride (PDADMACH) and Acremon LK 2 - a ternary copolymer of acrylic, methacrylic and maleic acids, as well as their salts. When choosing polyelectrolytes for the experiment, an important factor was the charge that they acquired when dissolved in water: for example, Acremon LK 2 is an anionic polyelectrolyte, and VPK-402 has a high cationic charge. Experiments to study the kinetics of sorption of silver ions were carried out using a limited volume solution method under static conditions from aqueous solutions of silver nitrate with stirring and thermostatting. Based on the data obtained, sorption kinetic curves were constructed and the sorption parameters of the process were calculated. The results of the study showed that when silver ions interact with non-activated natural materials, wool fiber exhibits the maximum sorption capacity, followed by cotton and linen fabrics. This indicates the potential of wool as an effective sorbent for silver ions. The intensifying effect of anionic polyelectrolyte on the absorption of silver by all types of fiber has been proven. Textile materials treated with silver preparations in combination with polyelectrolytes have high antibacterial characteristics. The finish has good resistance to wet treatments. The feasibility of preliminary activation of textile materials with a cationic polyelectrolyte has been shown, which allows obtaining high-quality antimicrobial finishing of textile materials.
