“…В ядро капсулы вводили маслорастворимый краситель Судан красный IV, моделируя процесс выделения активного вещества из капсулы. Исследованы параметры, характеризующие скорость выделения краси-теля из капсулы в зависимости от концентрации катионного полиэлектролита (КПЭ), применяемого для формирования ее оболочки [30][31][32]. Увеличение концентрации КПЭ в процессе синтеза капсулы приводит к образованию более плотной, менее проницаемой для функционального вещества оболочки капсулы.…”

The results of studies aimed at the creation of new functional textile materials through the use of microencapsulated TE (textile excipients) and metal nanoparticles, metal and non-metal oxides, as well as clays of natural origin were summarized. The developed methods for the synthesis of capsule shells of various architectures, including natural and synthetic polyelectrolytes, were presented. The technologies for encapsulation of functional preparations for aromatic, repellent and antibacterial finishing of textile materials were described. A description of the formation of microcapsules based on a highly active repellent drug - alpha-cypermethrin is given. An antimicrobial preparation containing silver nanoparticles has been developed, and recommendations for its use have been given. The production of silver nanoparticles were based on the reduction of metallic silver from silver nitrate using reducing agents such as glucose, glyoxal, and sodium dithionite in various concentrations. The sizes of synthesized particles vary from 145 to 2 nm. Modifying compositions based on synthetic polyelectrolytes and new complex compounds with predictable prolonged stability, functional substances and macrocycles (cyclodextrins (CD) and crown ethers) have been obtained. A technique was presented for the synthesis and strong fixation on cellulose fiber by introducing silver ions into the cavity of β-cyclodextrin of bioactive Ag-containing preparations with nanometer-sized particles. Methods for obtaining nanosized particles of zinc oxide were presented. Zinc acetate and zinc chloride were used as precursors. The sizes of the obtained nanoparticles are 70-90 nm. The technological bases for obtaining polyfunctional coatings on textile materials by impregnation and printing methods using polymers were described. The resulting coatings exhibit enhanced antibacterial and self-cleaning properties. The polyfunctionality of the action of fluorinated aluminosilicate in the processes of textile chemistry was shown.

“…The capsule shell architecture is made of polydimethyldialylammonium chloride and acrylic copolymer of acrylic, methacrylic, maleic acids, and their salts. We obtained a stable dispersion of microencapsulated acaricide-repellent preparation with particle size from 30-300 nm depending on the number of layers in the shell composition [87]. Suits treated with such a preparation ("Barrier-Insecto U") have been tested in the conditions of the natural focus of viral tick-borne encephalitis in natural biotopes of the Irkutsk region and Khanty-Mansiysk Autonomous Okrug.…”

Nanotechnologies play an important role in the modern world economy. As they deal, as a rule, together with other convergent (nano-, bio-, info-, cognitive) technologies. This connection causes a synergy effect, i.e. non linear development of innovations. The growth dynamics of the world's nanotechnology products is impressive. The world market of nanotechnologies in 2021 was 85 billion dollars, in 2024 (plan) will be 140 billion dollars. The forecast for 2030 is $288 billion. The production of nanoparticles of different nature and their use in different industries, fields of science, and technology takes a special place in nanotechnology. Both nanotechnology itself and the production and application of nanoparticles are interdisciplinary and cross-sectoral ones. Their users and customers are developed industries, including the textile industry. Metal nanoparticles are used both in the form of colloidal solutions and as part of microcapsules containing functional substances of different nature in the core. The article considers some methods of obtaining metal nanoparticles and microcapsule synthesis. The authors list the technologies of microcapsules application for textile functionalization.
