Core Spun Sewing Thread

Corespun threads, sometimes referred “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. 

Product Feature

This core contributes to higher strength per size (higher tenacity). The wrapper of a corespun thread can be either staple polyester or staple cotton. The wrapper gives the thread a fibrous surface that contributes to:
• A softer “hand” or feel than a 100% continuous filament threads
• A matte finish stitch appearance similar to a spun thread construction
• Superior frictional characteristics compared to a continuous filament threads

Material

Polyester continuous filament and Polyester or cotton staple
