In this review it is presented the insight of challenges faced by all branches of industry in the new age, and especially the maritime industry, strive for sustainable development, better energy control, use of materials with functional properties such as shape memory, all in the direction of increasing safety and comfort. Therefore, the development of new materials with shape memory, which is associated with the introduction of optimized production and the achievement of better func-tional properties. This leads to new applications in different systems and possible use on devices, which meet the rigorous requirements of the modern industry. The research into new materials with shape memory effect and their applied use in maritime is a challenge that many researchers have encountered in recent decades, and this is why in this paper we look at the basic engineering aspect of these materials and their current as well as future applications in the maritime industry. An overview of several innovations that testify shape memory effect and superelasticity in different maritime fields will be presented in this review.

Active clothing with protective properties adjusting to the level of hazards can be adopted at many workplaces e.g. in metallurgy. In particular, it concerns situations when the worker is not exposed constantly to the high level of hazardous factors, but only periodically e.g. during tlie inspection works. Therefore, a model of active clothing protecting against heat and flame is under the development within a project conducted in the CIOP-PIB. In this paper, assumptions fora construction of active textile systems intended for clothing protecting against heat and flame are presented and verified on a basis of laboratory tests. Tests of a resistance of textile systems to the radiant heat, as well as convective heat from the flame, indicated that implementation of distancing elements between the textile layers caused a creation of insulating air gap and as a consequence - an improvement of the selected protective properties. On a basis of test results, the most advantageous variant of materials with distancing elements has been chosen. For this variant, 80.0% increase of protective properties against radiant heat, and 74.3% increase against convective heat, have been achieved. These results confirm the correctness of undertaking research works aimed at the development of active protective clothing with shape memory elements for an improvement of safety and comfort at work in conditions of heat and flame hazards.

W artykule omówiono najbardziej znane grupy tekstyliów inteligentnych, stosowanych w odzieży. Tekstylne wyroby inteligentne można podzielić na dwie grupy: zmieniające swoje właściwości pod wpływem określonych bodźców (m.in. materiały z pamięcią kształtu i materiały przemiany fazowej) oraz elektroprzewodzące i zintegrowane z elektroniką. Tekstylia inteligentne mogą znaleść zastosowanie w konstrukcji ergonomicznych i aktywnych środków ochrony indywidualnej, a także monitorujących stan fizjologiczny organizmu ich użytkownika.

This paper presents the two most known groups of intelligent textiles which can be used in clothing. They are textiles that can change their properties after a specific stimulus (e.g., shape memory materials and phase change materials) and electroconductive textiles and textiles integrated with electronics. Intelligent textiles can be used in constructing ergonomic and active personal protective equipment, they can also monitor the user's physiological condition.
