A functional modelling of supportive clothing is proposed in this paper. Body forms and measures were analysed. The digitisation of the human body was performed by 3D scanning, and based on point clouds measurements were taken. and the forms of body parts for which the pattern of clothing was developed, were defined. Pattern parts of the male supportive underwear model proposed were translated into numeric form, and a program was developed in the C++ programming language through which the pattern parts are adjusted to individual measurements and to the material used for the compression of parts of the body. Since clothing can be used post-operatively as well, an analysis of the biodegradable Tencel® materials proposed to be used for these applications was conducted. Material samples were subjected to steam sterilisation at 134 °C, after which tests of microbial barrier permeability were performed using the new method. Aerobic bacterial endospores were used. Based on the samples tested and their properties, the construction of supportive medical clothing which, by their design, enhance the functionality and possibility of preventing infections of a body part subjected to surgery was carried out.

W artykule zaproponowano projektowanie funkcjonalnej bielizny męskiej. Analizowano kształt ciała i wymiary. Digitalizacja ludzkiego ciała została przeprowadzona za pomocą skanowania 3D, wykonano pomiary na podstawie „chmur” punktów i określono kształt ciała, dla których opracowano wzór bielizny. Proponowane fragmenty męskiego modelu bielizny zostały przekształcone na postać numeryczną, a program został opracowany w języku programowania C++, dzięki czemu części wzoru zostały dostosowane do indywidualnych pomiarów i materiału użytego do kompresji ciała. Ponieważ bielizna funkcjonalna może być również używana pooperacyjnie, przeprowadzono analizę materiałów biodegradowalnych Tencel® proponowanych do zastosowania w tych przypadkach. Próbki materiału poddano sterylizacji parowej w temperaturze 134 °C, po czym przeprowadzono testy przepuszczalności barier mikrobiologicznych przy użyciu nowej metody. W oparciu o przebadane próbki i ich właściwości wykonano funkcjonalną bieliznę medyczną, która poprzez swoją funkcjonalną konstrukcję poprawiła możliwość zapobiegania zakażeniom części ciała po zabiegach chirurgicznych.

In this research, the use of new technologies for the development of special protective overall for sport aircraft pilots was studied, with a focus on a comparative analysis of the static and dynamic body postures’ dimensions, intended for the development of the overall’s pattern design. For this purpose, digitalization of five male persons was carried out with the 3D human body scanner Vitus Smart by using 3D printed markers, precisely positioned on defined body locations, intended for exact measurement of body dimensions. Male persons, aged between 19 and 35 years with the same athletic body type and different body heights and body mass indexes (BMIs), were scanned in a standard static standing body posture and three dynamic body postures. A comparative analysis between the static and dynamic body postures was carried out. Based on the established body dimensions and girth dimensions of the 3D body model with 3D-modeled compression elements, made-to-measure construction of the overall pattern design was carried out. The function of these compression elements is redistribution of the blood from the lower extremities to the upper body parts at the appearance of high g-forces. Therefore, increased girth dimensions due to the use of compression elements were applied in the overall development process as construction measures with needed ease allowances. The functionality of the developed special protective overall was explored on the scanned 3D body model with 3D-modeled compression elements in a real sitting posture of the sport aircraft pilot in a cab by using virtual prototyping. The virtual simulation technology showed that a well-fitted protective overall for sport aircraft pilots can be developed by using a 3D scanned body model of a person in a sitting posture and its 3D body dimensions.
