Sažetak
For a number of human activities, a knowledge on yarn knotting techniques is extremely important in order to ensure high level of safety. This paper focuses at investigation of knotted yarns used for scouting, but can also be applied for similar activities, like mountain climbing. In the introductory part of the paper is given a review of the scouting activity and importance of yarn knotting. It is followed by results of previous investigation.The main objective of the present paper is to examine the tensile properties of knotted yarns, i.e. yarns that are tied to various scouting knots. The investigations are carried out on knotted yarns in 4 different states: (a) in dry state, (b) in dry state, after exposure to aging in water, c) in wet state, after exposure to aging in water, (d) in dry state after 100 cycles of abrasion and (e) in dry state after 300 cycles of abrasion. The results obtained are compared and conclusions are drawn. The importance of the presented examination is evident in the fact that knowledge on the tensile properties of targeted samples is essential for the preservation of personal and general safety of the individuals who use them
