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.

“…Huntite (Mg3Ca(CO3)4) and hydromagnesite (Mg5(CO3) 4(OH)2.4H2O) mixture as flame retardant agent exhibit the endothermical decomposition between 200 and 400 oC and releases water vapor and/or carbon dioxide, which gives rise to fall down of temperature, the dilution of flammable gases and isolation of flame [2][3][4][5]. APP as an acid source would collaborate with fabric with necessity additional carbon source such as chitosan to improve the efficiency.…”

In this study, it was investigated the coating of cotton fabric with huntite-hydromagnesite (HH) or ammonium polyphosphate (APP) solutions as anionic layer and chitosan solutions and nanosols as cationic layer by layer-by-layer (LBL) assembly to gain flame retardancy and antibacterial properties. Growth bilayer number, drying conditions and anionic layer type (HH or APP) affected the flame retardancy and antibacterial properties of coating with LBL assembly. 17% and 22% reduction in the peak heat release rate and 69% and 87% reduction in total smoke release and 26% and 14% reduction in mass loss rate were observed for fabric samples coated with AP solutions for 15 layers with drying after every dipping process (AP15DE) and fabric samples coated with HH solutions for 15 layers with drying after every dipping process, (H15DE) respectively. Thermogravimetric analysis revealed that the residual chars at 600 oC in air increased. The AP15DE exhibited the antibacterial activity against E. coli and S. aureus while H15DE displayed the antibacterial activity against only S. aureus.
