Abstract

The aim of this research was to analyse possibilities of making different woollen blend yarns with sheep’s wool and dog’s hair fibers and to investigate geometrical and mechanical properties of these yarns. In this paper sheep’s wool and dogs’ hair fibers were compared one with other in different geometrical (fibre surface, length, diameter, linear density) and mechanical (breaking tenacity, elongation at break, breaking toughness) properties. It was estimated that the sheep’s and the dog’s fibers are visually very different, they have various types of scales, also most of the dog’s hair have channels inside them. On the next stage of this work the woollen blend yarns were made by mixing the wool of German Blackface sheep with different breed (English Spaniel, Poodle, Yorkshire Terrier) dogs’ hair 15 %, 25 % and 35 %. After evaluating the linear density and mechanical properties of woollen blend yarns, it was estimated that influence of fiber composition in the yarns on these properties is different. Different values of the investigated properties are mostly influenced by spinning system of these yarns. The condenser spinning system affects inequality and unpredictable properties of woollen blend yarns. Also, obtained results depend on the breed of protein fibers, hairy surface, hollow structure and bending rigidity of fiber, the technological process or even compatibility of used devices.
