The tensile properties of yarns tied to the scout knots

The knowledge of knotting techniques on yarns with complex constructions is extremely important in a series of activities. One such activity is the scouting, towards which this paper is focused. In the introductory part of the paper is given a review of the types of yarns related to the formation of scout knots. The main objective of the paper is to examine the tensile properties of yarns that are tied to various scouting knots and furhrermore, to determine which knot is more appropriate for the use regarding the values. On the basis of the measurements, it was found that the breaking elongation is the highest for the the yarn tied to figure eight double knot. As far as the braking force is concerned, the highest values have yarns tied to granny knot. The importance of the examination is evident in the fact that knowledge about the tensile properties of the underlying samples is essential for the preservation of personal and general safety of the persons who use them.
