DESIGN OF CONSTRUCTIONS AND TECHNOLOGIES OF ADAPTIVE SOCKS FOR PEOPLE WITH CALF SICKNESS

Abstract

Development of functional socks for people with special needs who have diseases associated with ankle defects, including patients with diabetes.
Methodology. The analytical method of reviewing scientifi c, technical, and patent documentation in the fi eld of research is used in the work. An experimental method for determining the elongation on a tensile tester WDW-05M, unfolding method.  Analysis of problems associated with the elimination of excess pressure of the sock on the foot in people with increased measurements of the feet and ankles due to gunshot wounds, injuries or chronic diseases, including varicose veins, diabetes, edema, tumors, etc. confi rms the need to deve lop a new range of functional sock products. In the course of the research, the properties of weft-knitted
structures were analyzed and a scientifi cally substantiated design of adaptive socks for home use was proposed. The design includes at least two sections, the elastic properties of which diff er. The back side
of the leg, heel, sole, and toe are made of 1x1 rib knit, the instep and the front part of the leg are made of 3x3 rib knit. The section with higher stretchability and elasticity, made of 3x3 rib knit, softly maintains the shape of the socks’ leg, practically without creating pressure on the ankle and allowing to signifi cantly increase the perimeter of the sock in the area of the foot, toes, and/or heel. A sam ple of adaptive socks made of PAN yarn 32x2 tex х4 by knitting according to the shape of the unfolding of
its 3D surface was made on the fl at knitting machine PVRK of the 8-th gauge. The connection of the product's parts in order to give the product a three-dimensional shape is made on a linker machine Hague D280E.
Practical value. The design and technology of manufacturing functional socks have been developed. It is proposed to use industrial and semi-industrial double-bed fl at-knitting machines as technologic al
equipment for their production. The use of various rib knit patterns for diff erent functional zones o f a sock allows providing the set value of conditional tension of threads when using the sock on a foot of
atypical measurements.
