The effects of inlay yarn amount and yarn count on extensibility and bursting strength of compression stockings

Abstract

In this study, an experimental work is presented to determine the effects of body and inlay yam counts and inlay yam amount on the extensibility and the bursting strength of knitted compression stockings. For this purpose calf high compression stockings were produced, and then bursting strength and extensibility of these stockings were tested.

The results reveal that, when the course number of inlay yams at knit structure increases, there is a significant decrease in course way extensibility values of compression stockings. Bursting strength values of compression stockings knitted with coarse body and/or inlay yams were higher than that of compression stockings with fine body and/or inlay yam. The compression stockings with coarse inlay yams have the highest course way extensibility values. As the result of correlation analysis, we confirmed that at there was the strong correlation between "fabric way strain" which obtained by extensibility test and "the strain" which obtained by bursting strength test.
