Abstract
Purpose
The purpose of this article is the development of up-to-date equipment for making nanocomposites for investigation of the antimicrobial properties of nanotextiles and the creation of a scientific base to choose materials of clothing with a special purpose.
Design/methodology/approach
Investigations are focussed on modifying the surface of textile materials by metal ions nanoparticles (AgJ, CuJ). The work of the equipment is based on the creation of metal nanocomposites in polyethyleneglycol (PEG). It is heated up to a temperature of not more than 130ºС, followed by adding the dispersion of metal in small portions to water. Nanoparticles are uniformly distributed on material surface that provides the improvement of its characteristics.
Findings
It has been found that modifying natural fibrous materials by nanoparticles of metal ions (AgJ, CuJ) promotes increasing their bactericidal and fungicidal properties with a comparison with traditional cotton materials. Microbiological investigations of antimicrobial properties of the cotton fabric have been conducted according to their effects on staphylococcus bacteria, E. coli and fungi.
Research limitations/implications
This research is limited to cotton fabrics. Therefore, other fabric types can be investigated to expand the data basis in the future.
Practical implications
The main practical point of developed equipment is that it can be used for obtaining bactericidal and fungicidal properties of natural and fibrous materials modified by nanoparticles of metal ions (AgJ, CuJ). That provides new characteristics of textile materials that can be used in the future for special clothing tailoring.
Social implications
The use of engineering equipment will allow in perspective to produce clothes with bactericidal and fungicidal properties, which can improve people’s lives through the prism of health and finished product quality.
Originality/value
Special equipment for investigation of antimicrobial properties of nanomodified textile materials of different kinds has been engineered, and there is an opportunity to create materials with antibacterial and antifungal properties. The application of this equipment provides the receiving of new characteristics for textile materials with silver ions nanoparticles. Such properties of nanomodified materials are useful for human health and can be used in the production of various textile products.

Abstract
Purpose
The purpose of the work is development a novel of hydro-vibration technology for the formation of hats from fabrics, which will expand the functionalities of application of various fabrics.
Design/methodology/approach
The work is based on a novel technology of forming hats from different fabrics with the use of liquid-active working environment (LAWE). This hydro-vibration technology is characterized by high efficiency, productivity, manufacturability and potential opportunities when compared to existing technologies. This allows expanding its range of applications and increase functionality.
Findings
In the article, hydro-vibration technology is developed for the formation of hats from fabrics. As a result of the experiment, regression dependences of the shape stability coefficient on the formation factors having a close correlation were obtained. The performed optimization allowed determining the optimal values of technological parameters of the vibroforming process from fabrics: LAWE pressure 0.26 MPa, vibration frequency LAWE 4.3 Hz, forming time 74 s.
Practical implications
The use of developed hydro-vibration technology has great practical significance in the textile industry. This technology increases labor productivity and reduces the cost of production of hats due to its high efficiency. Increased efficiency is provided by the use of special equipment, methods and optimal parameters of the hats formation. With sufficient refinement, the developed technology can be applied to other technological processes.
Originality/value
Originality of the work is using liquid-actin working environment at vibroforming of heads of headdresses from fabrics. It is determined that the use of LAWE is effective in the formation of hats. To ensure maximum plasticization of textile fibers in the fabric of the part and increase the force field, it is developed a novel hydro-vibration technology of forming the heads of hats from fabrics.
