Polyester Core Spun(poly-poly)

Made with a polyester continuous filament core and a polyester staple 
wrap, this is a high performance core spun thread designed to minimize 
sewing problems and maximize seam quality. It is stronger than other 
spun thread constructions, which means you can use a smaller thread 
size without lessening strength. Smaller thread sizes help to reduce 
seam puckering on today's high-tech fabrics. It delivers the ultimate 
in sew-ability on manual and automatic multi-directional sewing machines, 
with proven results.

Characteristics:
1) Improved seam strength over staple spun threads
2) The polyester cover provides an excellent abrasion resistance
3) Superior color fastness compared to polyester cotton
4) Excellent stitch formation with low tension, helping to reduce seam 
    pucker
5) Unique lubrication method to reduce needle heat and allow sewing on 
    high-speed multi-directional machines without interruption
6) Excellent resistance to chemicals and UV
