<i />"Green Synthesis" of Silver Nanoparticles to Give Antimicrobial Properties to Textile Materials
At present, the problem of obtaining textile materials (TM) with high protective antimicrobial properties for various fields of application remains relevant. Imparting antimicrobial properties to TM has two basic goals: protection a person from the action of microorganisms (for this, dressings, medical applications, etc. are used) and protection from the action of pathogenic microflora of objects in contact with textile materials (shoe covers, medical gowns, medical and bed underwear, etc.). This is primarily due to the ever-increasing risk of exposure to pathogenic microorganisms on the human body and the emergence of their resistance to existing antimicrobial drugs. At the same time, the emergence of resistance was observe in microorganisms of various groups. It is possible to neutralize such a negative phenomenon by using silver nanoparticles for processing textile materials, which have a developed surface and unique antibacterial activity. The paper describes two methods for the synthesis of silver nanoparticles and the preparation of antibacterial materials and resistance to a wide range of microorganisms groups. Two methods for the synthesis of AgNPs and the preparation of antibacterial materials was used. The effectiveness of using sodium alginate for the preparation of NPs included in the printed composition based on sodium alginate was showed. The sizes (up to 60 nm) and shape of AgNPs were determined by spectrophotometry and electron probe microscopy. A composition for obtaining silver hydrosols in solution has been developed, including a reducing agent - glucose monosaccharide and a stabilizer - polyvinylpyrrolidone. The sizes of AgNPs were determined by the method of dynamic light scattering and amounted to 70-90 nm. The antibacterial activity of textile materials treated with synthesized AgNPs was confirmed.
