Abstract
Purpose
The purpose of this paper is to present the influence of modifying the fabric surface made from basalt fibers by the magnetron sputtering of chromium and aluminum layers on its resistance to contact heat and comfort properties.
Design/methodology/approach
In order to modify the surface of basalt fabric, the process of physical deposition from the gas phase was used. It relies on creating a coating on a selected substrate by applying physical atoms, molecules or ions of specific chemical compounds. The trial of modification was carried out using the magnetron sputtering method due to the material versatility, application flexibility and ability to apply layers on substrates of various sizes and properties.
Findings
The findings obtained regarding the heat resistance to contact heat and thermal insulation (comfort) properties show different values depending on the type of metal deposited and the thickness of coating layer. It was found that the modification of basalt fabric surface at the micrometer level changes the tested parameters.
Research limitations/implications
This paper presents the results of resistance to contact heat and thermal insulation properties only for the twill fabric made of basalt fiber. The surface modification of fabric was carried out using the chromium and aluminum of two values of layer thickness (1 and 5 µm).
Originality/value
So far, no tests have been carried out to modify the surface of fabric made from basalt fiber yarns using the magnetron sputtering method. In addition, it has not been studied, how the modification of fabric affects its resistance to contact heat and thermophysiological properties.

Abstract
The chapter discusses the effects of climate change on tourism development in Estonia, Latvia, and Lithuania by combining these countries into a single Eastern Baltic Sea Region. The chapter explores the current situation and investigates the trends that will affect the economic development if the present climate conditions are situated in historical context. The first part discusses how destinations can be better managed if they are informed by the scholarship on ecological modernization and updated by a coevolutionary approach to climate change. This discussion proceeds with an analysis of the impact climate change has on tourism following different scenarios of current and future climate conditions. The development of tourism in the Baltic countries is then assessed with references to sustainable development. Overall the chapter demonstrates how destinations can cope with the changing preferences of tourists even in the face of highly unpredictable climatic developments.

Abstract
Examines the thirteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
Purpose
The purpose of this paper is to develop artificial neural networks (ANNs) allowing us to simulate the local thermal insulation of clothing protecting against cold on a basis of the characteristics of materials and design solutions used.
Design/methodology/approach
For this purpose, laboratory tests of thermal insulation of clothing protecting against cold as well as thermal resistance of textile systems used in the clothing were performed. These tests were conducted with a use of thermal manikin and so-called skin model, respectively. On a basis of results gathered, 12 ANNs were developed that correspond to each thermal manikin’s segment besides hands and feet which are not covered by protective clothing.
Findings
In order to obtain high level of simulations, optimization measures for the developed ANNs were introduced. Finally, conducted validation indicated a very high correlation (above 0.95) between theoretical and experimental results, as well as a low error of the simulations (max 8 percent).
Originality/value
The literature reports addressing the problem of modeling thermal insulation of clothing focus mainly on the impact of the degree of fit and the velocity of air movement on thermal insulation properties, whereas reports dedicated to modeling the impact of the construction of clothing protecting against cold as well as of diverse material systems used within one design of clothing on its thermal insulation are scarce.

Abstract
One of the fundamental human requirements is a working environment that allows people to perform their work optimally under comfortable conditions. Given that buildings and air conditioning systems are designed on the basis of a certain level of discomfort, this raises the key question ‘What is the effect of the level of comfort on the productivity of people working in office environments?’ The purpose of this paper is to quantify this relationship as an aid to making choices regarding the working environment at strategic level within the facilities management process, with particular emphasis on thermal conditions.

Abstract
Looks at the eighth published year of the ITCRR and the research, from far and near, involved in this. Muses on the fact that, though all the usual processes are to the fore, the downside part of the industry is garment making which is the least developed side. Posits that the manufacture of clothing needs to become more technologically advanced as does retailing. Closes by emphasising support for the community in all its efforts.

Abstract
Purpose
For years, the main reason for using textiles in the health care sector was to protect the patient from the medical staff. Nowadays, the garment has to play another role and protect the wearer. For dentists, risks can come from saliva which is considered potentially infectious because it frequently contains blood. This paper aims to define dentist gown specifications according to the new situation, and to propose new garments providing safety protective function as well as comfort.
Design/methodology/approach
Enquiries, direct interviews as well as internet forums have been used to extract dentists' requirements taking into account their need of barrier and their comfort concerns. Studies of the spraying area on the gowns have been performed to define the location of the required protection. A study of the warmer zone of the garment via IR camera has been done. Two prototypes have then been constructed and tested.
Findings
Images of impacts of drops that could cause cross‐infection allow defining the zones which are to be specifically protected. Thermographic images provide maps of hot zones of the garment when worn in working conditions, and information is obtained of desired open space zones which have been designed to create preferential ventilation required for comfort improvement. A second prototype was designed to improve results of the first one.
Practical implications
Replacement of current dentists garment in routine situation.
Originality/value
Dentists' gowns used in dental care have not been studied and not been redesigned yet, whereas new dentists are facing new risks and eagerly looking for personal protective equipment providing safety protective function as well as comfort.

Abstract
Purpose
The purpose of this paper is to analyze the corona discharge films (CDFs) taken from the fingertips of human subjects who had contact for a long period of time with two sets of clothes, in order to establish in what way a long period of contact with textiles influences life's parameters: the heart beat (HB), the blood pressure (BP), and the volunteers' level of comfort.
Design/methodology/approach
Three volunteers took part in the experiments. They were placing a fingertip in the area of a strong electrical field of high voltage (10 kV) and high frequency (1,024 Hz) to register a CDF. A digital camera placed within the area of corona discharges records this phenomenon.
Findings
The paper finds that there is no statistical difference between the parameters of a CDF taken from the fingertips of volunteers after 5 h of wearing two sets of clothes. There is a connection between the level of comfort of the volunteers and their CDF.
Originality/value
The CDF shows the consequence of the different factors, impact on human subjects. The authors are moderate in their opinion about the influence of extreme textiles‐related feelings.
