CORESPUN VERSUS SPUN POLY Threads
What are the major differences between A&E’s corespun brands like Perma Core® and
D-Core® and Spun Polyester know in Asia as “pp” threads? What impact does using
one versus the other have on the quality of your sewn products?
Corespun threads, sometimes referred “pcore” or “polycore” or “cottoncore”, are
made by wrapping a staple polyester or cotton wrapper around a continuous filament
bundle of polyester fibers during spinning, and then plying these yarns into a sewing
thread. The continuous filament polyester core makes up approximately 60% of the
thread construction. This core contributes to:
• Higher strength per size (higher tenacity)
• Greater uniformity in size, strength and other physical characteristics
• A higher initial modulus or resistance to stretching contributing to better loop
formation and reduced seam puckering.
• Better ply security – fewer unravel type thread breaks
• Superior abrasion resistance & durability
