In this study, different amounts of lubricant were applied to air-jet polyester, polyester-spun, core-spun (poly/poly) and cotton ring sewing threads having the same final count. Mechanical and frictional properties of these sewing threads were measured. An evaluation was made in order to determine the effect of the amount of lubrication on yarn elongation, frictional forces, friction coefficient, electrostatic charging and seam breaking strength of different sewing thread types. The relationship between yarn strength and seam breaking strength was also evaluated.
