As a visiting professor at the Faculty of Textile Technology, University of I am prepared and published the academic textbook. This work, estimated by the reviewer to have a connotation of a scientific book, deals with the objective evaluation of textile materials and clothing, based on the mechanics of flat textiles. The central part of the topic deals with mechanics of textiles from the point of view of elastic deformation that occur in textile material during production, resp. processing of textiles as a result of different elastic loadings, such as simple (tensile, compression, shearing, bending and torsion) and complex deformation. The seven chapters of the book provide a detailed coverage of objective evaluation regarding textile structures and clothing. The introductory part presents the role of mechanics, resp. mechanical properties of fabrics for the engineering approach to the study. The second chapter deals with the development and the role of basic and applied research in the field of the mechanical properties of textile materials. The importance and theoretical basis of elastic deformation of textile materials are presented in the third chapter, which is the starting point for further understanding of the objective measurement of the mechanical properties of flat textiles. The fourth chapter presents the evaluation methodology of fabric hand as a starting point for the development of the objective measurement of mechanical and physical properties of fabrics, which is needed for the development of new technologies in garment engineering. The methodology of objectively measuring the mechanical and physical properties of textile fabrics, which represents an important tool for the quality control of textile materials during the production and finishing processes, as well as during fabrics’ processing within the garment industry, is presented in chapter five in three subchapters. The penultimate chapter presents the objective evaluation of garment appearance with an emphasis on the impact of the mechanical properties of the fabric on its behaviour during the garment manufacturing processes. The final chapter deals with the garment design quality based on the mechanical and physical properties of the fabric. The work is fitted with many mathematical expressions and illustrations and is enriched with many knowledge and achievements of own research, research and the results achieved within the research program. According to decision of the Senate of the University of Zagreb, Class: 032-01/11-01/50, No: 380-061-117-12-3 from October 17, 2012., the manuscript entitled Objective evaluation of textile materials and clothing, author Jelka Geršak has approved use of the title of a university textbook (Manualia Universitatis Studiorum Zagrabiensis).

COBISS.SI-ID: 17645590Measuring system for programmed measurement and evaluation of mechanical properties of liner and flat flexible materials consists of the measurement hardware with built-in measuring unit with the sensor system for testing tensile and/or compression loads and their mechanical deformations. Furthermore, the system has appropriate software for programming and controlling the measurement process, automated data acquisition, evaluation and display of results. It is intended for testing and programmed measuring of various mechanical deformations of linear flexible materials such as threads, yarns, ribbons, and flat materials such as woven and knitted fabrics, nonwoven textiles, leather, laminates, and composites. The deformations in these materials are a consequence of tensile forces and/or longitudinal compressive forces, deformations in cyclic loading and relaxation of tension in flexible materials. Hardware design solution with the corresponding software enables automated capture of numerical data of load-deformation measurements, calculation of the average stress-strain curve and numerical evaluation of parameters of viscoelastic properties of flat and linear materials. The system uses two sensors. For lower loads it uses an inductive force transducer while for higher loads a resistive force transducer is used.

COBISS.SI-ID: 16252438The very beginnings of the International CEEPUS Winter School Design Week goes back to 2012, when the concept of the Winter School was conceived. Its aim is to cover the whole spectrum of modern engineering design, clothing and/or other textile forms in the broadest sense, including the closely related areas, such as: Art, colour/light theory, fashion theory, photography, smart and intelligent materials, wearable computer technology, human-clothing systems, ergonomics of the thermal environment and innovativeness. The aim of this interdisciplinary concept of a Winter School, which can be understood as the interaction of different disciplines, is to combine scientific and artistic disciplines and connect the creativity of students from different universities and from various countries. In the framework of lectures and a wide range of targeted Workshops, the students dealt with the theoretical and practical aspects of design in the broadest sense. Here, a broad openness to different disciplines was required, which allowed interaction between science, art and society, the development of new ideas and their application in a real environment. The topic of the fifth International CEEPUS Winter School Design Week 2016, which took place under the motto Design in the Light of the Light - New Challenges - New Solutions, reaffirmed again the wide openness to different disciplines. The International CEEPUS Winter School Design Week 2016 took place from 16. 10. 2016 to 22. 10. 2016 at the Faculty of Mechanical Engineering, University of Maribor. It was organised by the Research and Innovation Centre for Design and Clothing Science. Solutions was the motivation that connected this year’s participants. Winter School Design Week 2016 brought together scientific and artistic disciplines and connected the creativity of students from different universities and countries. Winter School participants developed through interdisciplinary designed creative Workshops (Light-Dark, Fashion in the light of technology, The play of the light, 3D modelling tools helping the clothing design process, Portfolio, Photography – painting with light, Transparency, Study of white matter’s transparency in the case of small white dresses) a collective philosophy of ideas, as a key element in the search for new solutions. The CEEPUS Winter School was attended by 81 participants, 40 foreign students from 9 different universities from 6 countries (Croatia, Slovakia, the Czech Republic, Serbia, Bosnia and Herzegovina and Romania), 25 students from the Department of Textile Materials and Design, 6 students from the Department of Engineering Design at the Faculty of Mechanical Engineering, University Maribor, as well as 10 students from secondary schools. Realization of the International Winter School involved renowned foreign and domestic experts, including: Prof. Anu Kylmanen and Prof. Päivi Rautajoki from the Faculty of Art and Design University of Lapland, Finland, Prof. Karin Košak from the Faculty of Natural Sciences and Engineering, University of Ljubljana, Assoc. Prof. Andrea Pavetić from the Faculty of Textile Technology, University of Zagreb, Croatia, Assoc. Prof. Maria Fulkova and Jaroslava Frajova from the Academy of Fine Arts and Design in Bratislava, Slovakia, Mag. Kiki Klimt from Ljubljana, Dr. Sc. Željko Knezić and Petra Krpan, MA from the Faculty of Textile Technology, University of Zagreb, Croatia, and others. As an important achievement of the 5th International CEEPUS Winter School we can highlight, from many new ideas and solutions, the prototype of an intelligent fest dress with built-in lighting effects. The garment is a reflection of the co-harmony of fashion and technology, that fits into the garment integrated miniaturized electronic components that allow specific functional effects, based on the development of their own applications. The 5th International CEEPUS Winter School was marked by a specific, extremely rich structure of participants.

COBISS.SI-ID: 15772950For today's buyer it is not enough that clothing satisfies only basic functions, such as body protection and functionality. It is expected that clothing satisfies fashion demands such as shape, colour and material. Furthermore, the clothing should assure us to feel comfortable, attractive and relaxed. Comfort while wearing is important clothing qualitative characteristic mainly consisting of these three components, which should be optimized according to textile and clothing construction: thermo-physiological, ergonomic and mechanical comfort while wearing. Various number of factors have impact on sense of a comfort as in an example: kind of the material, which is used in garment production (raw material, surface mass, treatment type, touch, physical, mechanical and thermal features), construction of the clothing cut and other. The comfort while wearing the clothing represents the result of a balanced process heat exchange between the body, clothing and environment and depends on special thermal characteristics of clothing that represent its ability to transfer heat and moisture from the surface of the human body in the environment. The measuring magnitudes, which are the reflection of those abilities, are thermal resistance or thermal insulation of the clothing Rc and clothing water vapour resistance Re. With regard to the doctoral thesis the influence of the material properties for summer womenćs clothing on thermo-physiological comfort while wearing in warm environment was investigated. The warm environment corresponds to high summer temperatures. For this purpose five fabrics were manufactured according to the plan of experiment and defined materials (natural fibres (linen, cotton), synthetic (polyester) and mixtures there of), which have approximately equal surface mass, but different raw material. Based on the research of physical, thermal and mechanical properties of the manufactured fabrics, and research of the body covering with the clothing on thermophysiological comfort, the two models of womenćs clothing for warm environment were designed and manufactured. Investigation of the influence of fabrics properties on thermo-physiological comfort of clothing was performed at different climatic conditions that were artificially set up in climate chamber, i.e. at three ambient temperatures (25 oC, 30 oC and 35 oC), wind movement velocities (0,2 ms-1, 0,5 ms-1 and 1,2 ms-1) and at constant relative humidity of 40 %, where the tested persons carried out the following activities (20 min acclimatization, 20 min flat walking in the direction of wind at velocity of 2,5 kmh-1, 5 min rest and 20 min walking of velocity of 3 kmh-1 in the direction of wind). Climate conditions were determined according to the data from Hydrometric institute of Banja luka. The average summer temperatures, noted for four months in the last three months, were applied. The influence of the clothing fabrics on thermo-physiological comfort was experimentally determined as a change of the three physiological parameters: average skin temperature, heart rate and amount of evaporated sweat, resp. skin humidity and amount of accumulated sweat in the clothing. The impact of the individual thermal clothing characteristics on subjective perception of the comfort was established by questionnaire with special scales by appreciation. The tested persons were answering before, during and after the investigation. Based on research results of the physical, mechanical, thermal and sorption properties of the clothing fabrics and results of the evaporated sweat amount in the analysed models while wearing the clothes it is established that evaporated sweat amount depends on the woven fabricsć properties (surface mass, fabricsć relative humidity, air permeability and water retention).
