All the actions tending to limit the number of road accidents are very important. One of such an activity done byroad users is wearing the warning clothing containing reflectivematerials and elements. Warning clothing enables noticing the moving person in good and/or bad atmospheric conditions. Reflective eiementspiaced on the clothing improve the visibility not only pedestrians, but also the other road users, for example, bicycle riders. In the paper there is presented the designed project of warning clothing - bicycle rider jacket and there are presented results of questionnaire and of visibility measurementsof jacket on the road in the darkness.

The task of clothing is to provide a state of physiological comfort. The criterion for identifying the physiological comfort is to ensure thermal equilibrium of the body. The possibility of heat exchange between human body and the environment is the result of processes: radiation, convection, evaporation of sweat, breathing. Depending on the intensity of effort and environmental conditions the contribution of these processes is different. The state of thermal comfort is affected by the biophysical properties of clothing: aeration, water vaporpermeability, hygroscopicity, water resistance and thermal insulation [9]. The research of heat transport is carried out in dynamic conditions using a new method of „artificial skin model", with which the amount of heat diffusing through the sample is determined. Another method for measuring the heat flux and the analysis of thermal capacity of textile products is with the use of the alambeta device. The article presents the results of thermal insulation (for 15 samples) that were conducted on the device of alambeta and „artificial skin model". [ABSTRACT FROM AUTHOR]

A phase change material (PCM) is a substance, which changes from the solid to liquid and vice versa at a certain temperature. This material absorbs, stores and releases large amounts of energy at this temperature. Many scientists are interested in a quality of PCM, especially in its cooling property, also in textiles. In Reinertsen & co. work, two cooling vests for suergeon were developed." the first one with the organic PCM--fibres with microcapsules filled with paraffines, and the second one with the inorganic PCM--Glauber's salt. Both vests improved moisture transfer, however, the cooling quality of the vest with the organic PCM was only 30% of the cooling quality of the vest with Glauber's salt. The cooling vest with Glauber's salt was also designed for the firemen and the athletes preparing to the Olympic Games. Scientists" proved the cooling effect of this vest by two tests carried out on people in a climatized room. Glauber's salt was also used in a head cooling system for motor drivers to improve their concentration and to protect the head from the uncomfortable environment conditions. In spite of the fact that in textiles both the organic and inorganic PCMs are used, it's a hydrate, which gives the best results and moreover, is cheaper than encapsuled paraffines.

Textile materials destined for the protective clothing belong to the group of textiles, which are the most exposed on the Sun radiation and atmospherical factors. In result of it different changes, worsening the physical and physio-chemical fabric properties as well as color changes (fading). For measurements there were selected two groups of fabrics applied in the protective clothing constructions: materials of modified surface and resistant on the chemical means, flame resistant, of antielectrostattic properties and fluorescent fabrics of background of warning clothing, There is described the range and methodogy of ageing measurements i.e, color change, change of strength properties, flameretardancy, thermoinsulation, electrostatic properties and penetration and repellency by acids and alkali after the fabric exposition on the Sun radiation and atmospherical factors in the natural conditions.

The development of modem fabrics with heat function is a result of increasingly requirements of users towards high-tech clothing. The article describes the possibility of apply the electroconductive yarns in the heating textile materials. The test stand for evaluation the possibility of heating the material has been developed for these studies. Two variants of fabric with different contents of metal fibers have been elaborated. To observe thermal effects of the electroconductive fabric powered by electricity an infrared camera was used. [ABSTRACT FROM AUTHOR]
