Poly-Poly Core-Spun Thread

Supplied as raw white cones for dyeing and winding.

Poly-poly core-spun thread

A high-tenacity polyester filament core wrapped in polyester staple fiber, combining the strength of filament with the sewability of spun thread. A standard choice for mid- to high-end garments.

Why choose Poly-Poly Core-Spun Thread?

  • Clearly stronger than ordinary spun thread of the same count
  • A finer thread gives the same seam strength, for neater stitches
  • Fewer thread breaks at high sewing speeds
  • Staple-fiber surface with a soft, cotton-like look
