Abstract:

Based on the models developed, the changes in unit pressure exerted by ready-made compression products were evaluated in dependence on the longitudinal rigidity, compression class, dimensional tolerance and product size. Tests made it possible to determine the maximum permissible values of longitudinal rigidity for individual compression classes and product sizes, which, if not exceeded, ensure that the pressure exerted falls within the given compression class. Experimental verification carried out on an example of a commercial compression product from the first and second compression classes showed that the main reason for the differences between the declared and experimentally determined values of unit pressure was the overestimated longitudinal rigidity of the knitted fabric and dimensional tolerance of the size ranges and errors in the design procedure, resulting from not sticking to the principle of designing the product for the middle circumference value and the middle pressure from the compression class.
