This research presents the results of the study in which the artworks are exhibited to blind and visually impaired persons and an automatic verbal tour guide with capacitive sensors is implemented. The aim of the research is the development of a prototype for audio interpretation of 3D printed artworks for enhancement of the experience of blind and visually impaired persons. The proposed solution enable the blind and visually impaired persons to touch and hear information when accessing the 3D printed object, i.e. after the approatching of the 3D object and the user’s touch there is a programmed synchronised turn on of the voice explanining the set of information about the object. For each touched form (shape) of the artwork the blind and visually impaired person has a complete insight in relation with other shapes in the vicinity, and consequently the user is able to experience the whole artwork, to comprehend what it is all about, which artistic movements or age it belongs to, the handwriting of artist, and in the context of experiencing the exhibition place, the concept of the exhibition, etc. In front of each artwork there is a plate in Braille alphabet with the name of the artist, year of its creation, used technique, and the name of the gallery. Further, in the results the technology of the sensors is presented, their composition and the implementation in 3D printed objects is explained and based on a usability testing advantages and disadvantages of the presented application of capacitive sensors are critically discussed.

Barrier coatings of fibrous materials are of great interest for the packaging paper producers as increased resistance to oils, grease and other agents with the paper packaging increases the usability of the product. The barrier coatings have to withhold several parameters regarding resistance for the penetration of various agents, runnability on the machines regarding mechanical properties and also printability futures to enhance the packaging. Different sacks, bags and other products are mainly produced by coating the surface of the paper with the appropriate coatings which can be petroleum-based waxes, polymers solutions or pigments. By applying the barrier coatings the surface topography and porosity as well the surface chemistry is changed as the used polymers, waxes and other products which fill the fibrous network of the packaging change the macrostructure and induce different chemical compounds on the surface. These products are mainly printed with flexo technology We have checked the grease resistance with the KIT test (Tappi T 559), dynamic contact angle change, the penetration of liquids and the surface coverage of plasma treated waxed and base papers. Our results indicate improved printability and liquid penetration but also the lowering of grease resistance after plasma treatment. The treatment is possible but further adjustments regarding plasma power and time of treatment are needed to find the optimal parameters for different kind of barrier coated papers.

Dyes and pigments are important industrial chemicals. The structures of dyes can be very diverse and complex, so the treatment of wastewater containing these chemicals can be very challenging. Fenton process is particularly attractive and effective to degrade a wide range of dyes. In order to reduce the expenses related to applying these processes, the use of waste materials in the heterogeneous Fenton process, as alternative sources of catalytic iron, is recently investigated in scientific literature. In this study effluent was obtained from dye house unit of carpet factory (Serbia) and it contained the mixture of six commercial dyes. Pyrite cinder, a residue from sulfuric acid production, was also used in this process as a source of catalytic iron. Effluent decolourization rate reached 75% under optimal condition. Additionally, the research included further characterization of obtained effluent in terms of mineralization and metal leaching. A significant degree of mineralization was achieved under the applied conditions. Although, dye degradation was satisfactory, the metal content of the solutions after the process suggests that an additional treatment step, by using lime, is necessary. Results indicated that the applied waste material is effective as iron source in modified Fenton processes for treatment of effluent containing mixture of dyes.

This research observes alteration in optical properties of two commercially available hemp office papers exposed to various methods of accelerated ageing. Both handmade office papers, natural colored and non-chlorine bleached were formed from 100% hemp plant fiber. In order to establish their optical stability under controlled conditions two different accelerating ageing treatments were carried out for the period of 24 hours as a simulation of different degradation processes that naturally occurs in cellulosic materials: thermal oxidation (TO) and photo-oxidation (PO). Before and after ageing treatments the changes in the optical properties of papers were monitored by X-rite DTP 20 spectrophotometer and obtained differences in Reflectance index (R), Euclidean difference (ΔE00*) and Yellowness Index (YI E313) have been discussed. The results have shown how the paper optical stability is dependent upon manufacturing process. Namely, it was found that bleached hemp pulp provide better optical stability of papers than unbleached hemp pulp.

Surface nonuniformity can appear at a print in two forms: random or as a systematic variation. Both types appear in digital printing, but in this study, an only random variation on the digital prints was analyzed. We used two methods for quantification of the nonuniformity: M Score and ISO methods, which are based on physical measurement of the prints, using one of the measuring instruments that measure the colourimetric (L*a*b* values) and densitometric (optical density) values. Samples used in this paper were generated using the software MATLAB Macro Uniformity Toolbox add-in that is printed on the same paper using ink jet printing machine Epson Stylus PRO 7800. We used spectrophotometer Eye One Pro2 and software Measure Tool to measure samples. Other calculations are done in a software application in Microsoft Excel. Based on the results obtained in the research, it is concluded that both methods can be used to measure the random variation of the print nonuniformity.

The human body transforms the chemical energy of the food into the work and the heat through the process of metabolism. The produced heat through the skin is transferred to the environment. In this case, in the state of thermal equilibrium, the amount of heat produced is equal to the amount of heat lost by conduction, convection, radiation, evaporation and breathing. The process of conduction of heat is transferred from the body to the environment, through layers of clothing and air, with the person standing still. Conductivity of heat in clothes depends on the thermal conductivity of the fibers from which the clothes are made, the conductivity of the air trapped in the pores of the clothes and the air on the surface of the clothing, the surface of the clothing layer through which the heat and the thickness of the clothes pass. The amount of heat transferred by conduction is usually negligible because the clothing, by its characteristics, slows down heat transfer in this way. Additionally, ink layers made in printing process significantly affect the properties of textile materials and clothes made from these materials. And today textile materials are increasingly being subjected to the process of printing due to aesthetic requirements of the people. This paper investigates the influence of digital printing parameters on the thermo-physiological features of textile materials. The essential print parameter was a different number of passes. In this research were used textile fabric materials of 100% cotton fibers. With printing process parameters, such as number of passes in the print, it is possible to influence the amount of ink that is applied on and in printed material, and thus the achievement of desired values of thermal parameters of printed materials. The influence of print parameters to thermo-physiological properties of the material is evaluated through a thermal conductivity and heat retention ability. Results of the research demonstrated that, in addition to material composition, the printing process with its parameters have a significant influence on the thermo-physiological characteristics of textile materials. The values of the thermal conductivity of the printed samples show that the increase in the number of application of ink in the printing results in a rise in the value of thermal conductivity coefficient, and decrease in heat retention ability value.
