摘要

A package of carbon filament yarn having no slipover tendency upon unwinding thereof, in which a yarn trace formed by a traverse is repeated every n cycles at a predetermined shifting ratio in a range of 50% to 150% relative to the yarn width, n being a positive integer of not more than 9. The package can be obtained by using a conventional spindle drive winder under a selected winding ratio and winding tension.
