Filament machine sewing thread

摘要

A filament machine sewing thread comprising a spun combined filament yarn obtained by combining polyester filaments A having an intrinsic viscosity [eta]F within the range of 0.7 to 1.2 with polyester filaments B having a lower intrinsic viscosity [eta]F than that of the polyester filaments A by 0.2 to 0.7 and a higher elongation than that of the polyester filaments A in a spinning stage.
