Evaluating Thermophysiological Comfort Using the Principles of Sensory Analysis

Thermophysiological comfort applies to the way in which clothing lets through or retains heat and moisture and helps the body retain heat balance in rest position or at various levels of activities. In this paper, the principles of sensory analysis are used to define the protocol of new method for the evaluation of thermophysiological comfort wearing different garments. Sensory analysis was chosen because as a scientific discipline that applies experiment principles using human senses is used for the evaluation of consumer goods. Test protocol using assessors described in this paper consists of the following steps: defining the interview content, finding potential assessors and making an interview, creating a survey, conducting a survey, group discussion, test and group discussion scoring, selection of assessors, assessment preparation and subjective assessment. On average the most distinctive increase in the sensation of warmth was recorded for the polyester clothing ensemble, and the lowest one for the cotton clothing ensemble. Concerning the average grades of comfort given by assesors, the most comfortable clothing ensemble is the one made of viscose. It was also found out that the method is especially suitable if a representative group of assessors is formed

Technology – Based Assessment of Soft Skills in Higher Education

The importance of soft skills, both for the learning process and employment, is well outlined in a number of documents and strategies. At the moment, digital badges seem to be an important technology that can be used to assess soft skills. Digital badges, or more specifically, Open Badges, provide a whole new way of issuing credentials to individuals that demonstrated certain skill. Furthermore, badges allow individuals to complete with themselves or others, and are good instrument that can motivate continued engagement. Taking all this into concern, it should be pointed out that digital badges have great potential to validate evidences of educational achievements in formal education. This paper describes the 4-phase model SAGRADA, developed within the EU LLP project GRASS, in order to support awarding badges. The whole process is additionally explained trough application case developed at one partner institution. The paper also gives overview of student’s reactions towards the whole badging principle and discusses the outcomes.

Design of fancy yarns for the collection of evening dresses

Different samples of fancy yarns are designed and produced using the twisting machine with hollow spindle. The designed yarns are used to create a collection of evening dresses and the main inspiration for the collection was the use of metalic yarn. In order to get the feedback from potential buyers of designed yarns, subjective assessment of yarns is carried out. At the core of methodological approach is the use of paired comparison test

Tjelesno mapiranje pomoću termografskih mjerenja pri različitim utjecajnim čimbenicima

The presented research focuses on the use of thermography to observe influences of different influencing factors on the changes of lower body temperatures. Based on the outcomes of the research fit of garment plays an important role for the retention of heat between the textile material and skin, especially in the zone of both upper and lower shin. Also only tight model of trousers is capable to preserve the temperature in zones of thigh and knees of male volunteer. The given body-maps present differences in values of average temperatures (ΔT) considering the garment fit. In the indoor environment, tight model of female trousers has significant influence on the average temperature in the zone of upper shin. This observation is even more pronounced in the outdoor environment. For the male volunteer, higher differences, between temperatures are seen in the outdoor environment only.Istraživanje se bavi korištenjem termografije za promatranje utjecaja različitih čimbenika na promjene temperature donjeg dijela tijela. Rezultati upućuju da pripijenost odjevnog predmeta ima važnu ulogu u zadržavanju topline između tekstilnog materijala i kože, posebno u zoni gornje i donje potkoljenice. Nadalje, samo pripijen model hlača može zadržati temperaturu u zonama natkoljenice i koljena kod muškog ispitanika. Predstavljene tjelesne mape prikazuju razlike vrijednosti prosječnih temperatura (ΔT) s obzirom na pripijenost odjevnog predmeta, tj. koliko tijesno ovaj pristaje uz tijelo. U zatvorenom prostoru tijesan model ženskih hlača znatno utječe na prosječnu temperaturu u zoni gornje potkoljenice. Ovaj je nalaz čak i više izražen u vanjskom prostoru. Kod muškog ispitanika veće razlike u temperaturi primjećuju se samo u vanjskom prostoru

Measurement of thermal parameters of skin-fabric environment

Background and Purpose: In combination with metabolic heat, the heat generated by human activities and worn garment produce 6 basic factors (sometimes called 6 basic parameters because they are in space and time, but fixed representative values are frequently used in analyses) which define thermal body environments. The aim of this paper is to investigate the impact of one parameter – clothing insulation on the total transfer of heat and water vapor. Materials and Methods: The measurement was carried out on knitted fabrics commercially used for the production of underwear or different types of next-to-skin-wear. The transfer of heat and moisture trough fabrics was observed in two simulated climatic environments (moderate and hot) with the constant parameters metabolic energy and air velocity. Results: The results indicated that the heat resistance increases by laying a knitted fabric layer or under real conditions when the body is dressed in lightweight knitwear by 25%. The test results of the samples under different environment conditions indicated a reduction in heat resistance under moderate conditions. It also applies to the measurement results of the resistance to water vapor transfer, but the differences within the observed relationships are higher than it was in the case of heat transfer resistance. Conclusions: The study showed that both heat and moisture transfers are freely movable controlling elements of comfort perception. Therefore, the optimal design of clothing systems is important factor of comfort
