At the International Conference of Technical Textiles, Nonwovens and Equipment Technotextil 2024 in Moscow, Ekaterina Tsobkallo, Head of the Department of Engineering Materials Science and Metrology of 草榴短视频, Scientific Director of the Laboratory of Mechanics of Oriented Polymers, Doctor of Technical Sciences, Professor, spoke at a panel discussion on innovations in the use of smart materials. She also spoke about the development of technologies for the production of new types of electrically conductive and antistatic materials from composite synthetic filaments containing various types of carbon nanofillers. Recall that one of the scientific partners of the business program of the conference, which was attended by representatives of Russia, India, China, Uzbekistan, Turkey and Tunisia, is the University of Industrial Technology and Design. We publish the main theses of the speech by Professor Ekaterina Tsobkallo at the Technotextil 2024 conference.

What needs to be produced.

Recently, the problem of creating textile materials from yarns with electrically conductive properties and heat-dissipating, heat-dissipating properties has become acute. Fibers for such materials must have high strength, manufacturability, and low specific gravity, which is not feasible in the case of using metal filaments.

A popular field of application today is the shielding of electromagnetic fields, the removal of static electricity, and heat鈥攄issipating properties. Static electrification of synthetic materials leads to violations of technological processes, especially in the presence of fire and explosive mixtures, dust and vapors of flammable liquids. Currently used domestic materials do not fully protect humans from the harmful effects of electromagnetic fields and static electricity.

The main results and directions of scientific research at the Department of Engineering Materials Science and Metrology of 草榴短视频.

The concept of creating technologies for the production of new types of electrically conductive, antistatic, shielding and heat-dissipating synthetic textile yarns and webs for the manufacture of work clothes, technical products that shield electromagnetic fields of webs, heat-dissipating materials has been developed.

Textile composite yarns of a new generation have been created based on a fiber-forming polymer matrix and carbon nanofillers of various types: carbon nanotubes, carbon black particles, carbon nanofibers with high mechanical properties, as well as electrical and thermal conductivity properties and others.

The theoretical foundations of forecasting and modeling of electro- and thermally conductive, physico-mechanical and special properties of nanostructured fibrous composite materials are being developed.

The results of the work will be used in the production of synthetic materials for technical purposes that have protective properties against the effects of static electricity and from the effects of an electromagnetic field. The improvement of the physical and mechanical properties of such materials will be achieved through the use of new carbon nanofillers 鈥� carbon nanotubes.

Development of domestic medical textile materials.

Medical textiles are used in endoprosthetics surgery. Currently, surgical braided meshes are the most common in the production of surgical non-absorbable endoprostheses. Mesh explants made of various synthetic materials are used. The main types of mesh surgical endoprostheses are synthetic, biological and with cellular coatings. Today, foreign analogues have a more diverse range, including bioresorbable materials and materials with cellular coatings, which in some cases are extremely in demand in surgery. From the analysis of the types and market of mesh endoprostheses, it follows that the development of domestic products capable of replacing imported analogues is an urgent and most important task in the field of medical materials science.

The Russian market of medical devices offers an assortment of mesh endoprostheses from domestic manufacturers, among which the main ones are Lintex LLC and Volot LLC. The products of these companies are mesh endoprostheses made on the basis of synthetic threads.

What is smart textiles today? What properties do such fabrics have?

With the simplest approach, "smart textiles" 鈥� innovative textile products of a new generation 鈥� are materials with a certain set of pre-designed special properties.

In a more general approach, textile and fibrous materials whose properties can change when exposed to various external factors, temperature, electromagnetic, and so on.

What is needed to attract young people to science at universities?

In order to attract young people, it is necessary to constantly update the instrument and technological bases and the availability of modern laboratories. It is necessary to form scientific groups of 3-5 people to solve the set scientific tasks. Young researchers need colleagues and a qualified supervisor. Research groups should have government funding. At the University of Industrial Technology and Design, for example, we attract lecturers from the BTK Holding to teach students disciplines in the field of special clothing. Of course, we must prepare graduates with a specific purpose for enterprises.
