Development of the lower limb stump prosthetic sock

Abstract

Prosthetics compensates for the negative effect of lower limbs amputation. The quality of the prosthesis depends on the quality of the prosthetic sock. The use of hybrid knitted fabrics, which combine the properties of several raw materials, makes it possible to create prosthetic socks with improved hygienic quality. Three variants of lower limb stump prosthetic sock samples of plush fabrics were produced on a Lonati DF 616 machine. The raw materials used in the samples were following: cotton yarn, polyester yarn, elastane yarn, polyamide yarn. Hygroscopicity and capillarity of the samples were researched. On the basis of the experimental data, it was recommended to produce the moisture- transferring layer of the prosthetic sock using polyester yarn. It was recommended to produce the moisture-absorbing layer of the prosthetic sock using cotton yarn. 3D model of the prosthetic sock knitted fabric was created and analyzed.
