Compression therapy along with the use of compression materials is one of the main prevention methods against scars and keloids. Compression knitted fabrics must be characterized by parameters that enabling to reaching class I compression (16–24 mmHg). When constant pressure higher than capillary vessels pressure is applied to scars, it will have a negative influence on formation of keloids and significantly prevents their hypertrophy. Long-term pressure causes tissue hypoxia, slowed-down metabolism, and reduction of the amount of fibroblasts. One of key elements of compression therapy is choosing the required knitted fabric with necessary structure and physicomechanical parameters as well as designing methodology based on Laplace law, which will ensure the application of desired value of single-unit pressure on post-burn scar. Apart from physicomechanical parameters, a medical device, such as compression garment, must be characterized by high level of biocompatibility. An added value in terms of functional parameters is the antibacterial action of the product. It was obtained from the fibers used which contain a compound in their matrix and out of which silver ions are released. Additionally, the antibacterial action was also obtained via impregnation of the knitted fabric in RUCO-BAC AGP which contains silver. In the course of the research presented in the article, compression fabric was designed with a special construction - a knitted fabric comprising two layers. The first layer, which is in direct contact with human skin, is manufactured out of a yarn with conductive-diffusive characteristics. The second layer is made of microfibers which keep the moisture out of skin surface and also diffuse it to the outside. The following article describes the final stage of developing a compression garment aiding the external treatment process; the mentioned stage is related to biological tests such as microbiological contamination, cytotoxicity, sensitization, and irritation. The article closes a series of publications presented by the Authors in bibliography. It also presents the antibacterial activity tests done on the developed double-layer knitted fabric enriched with silver. The obtained results suggest that the fabric may be used not only in compression therapy, but also in the field of cosmetics and aesthetics.

In this paper, a pressure sensing device for analysing pressure comfort on elastic garments was designed and developed. The device was calibrated and tested on different compression garments for its reliability. This pressure comfort measurement device is used to measure the pressure between the human body and garments. The fabric resistance due to each and every body movement is noted to evaluate the effect of fabric compression on body muscles in order to assess the pressure comfort for sports persons. The new device proved that elastic garments certainly improve stamina and speed through its quick recovery and lower stress with higher elongation. There is a good correlation found between the pressure values given by the new sensing device and the Instron tester.

Opracowano układ pomiarowy umożliwiający pomiar ciśnienia w układach ubiorów kompresyjnych mający istotny wpływ na komfort użytkowania takiej odzieży. Układ pozwala na pomiar ciśnienia pomiędzy ciałem człowieka a warstwa odzieży, również przy zróżnicowanych ruchach ciała, co jest niezbędne dla określenia komfortu odzieży np. w przypadku sportowców. Badania rożnych ubiorów kompresyjnych pozwoliły ocenić przyrząd jako dobrze nadający się do tego celu. Dzięki zastosowanemu przyrządowi udało się stwierdzić, że ubiory kompresyjne pozwalają na polepszenie zdolności wysiłkowej oraz szybkości regeneracji układów mięśniowych.
