core spun thread are made by wrapping spun thread ,the core is a continuous filament polyester thread during spinning, and then into a sewing thread. The continuous filament polyester core makes up approximately 65% 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
