This study examines how the counts of PET yarns and spandex fibers influence the properties of tubular knitted fabrics. PET yarns and spandex fibers with different counts are combined to form wrapped yarns, which are then made into tubular knitted fabrics. The surface of the knitted fabrics is observed, after which the knitted fabrics are tested for their tensile strength. The test results show that the tensile strength and thickness of the tubular knitted fabrics both increase as a result of the increasing content of PET yarns; however, the content of either spandex fiber or PET yarns is not correlated with the deformation of the tubular knitted fabrics.
