Abstract Elastane yarns are often used to produce stretch fabrics on knitting machines as well as rapier weaving machines. On air-jet weaving looms their use is still limited. That is why the objective of this paper is to investigate the weavability of elastane based stretch yarns on air-jet looms. Bobbins of elastane were woven on an air-jet loom and a distinction of the bobbins in three categories was made according to the most important production processes for elastane yarn: core twist, core spun and air covered. Yarn properties such as linear density, elongation at break and Air Index value were determined, weaving tests were performed and properties of the resulting fabric were determined.
