 * Core Spun Yarn * 

1.What is core spun Yarn?

 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

the wrapper of a corespun Yarn can be either staple polyester or staple cotton.

The wrapper gives the yarn 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
The Poly wrapper contributes to :
o Superior color fastness, chemical and abrasion resistance
o Higher strength than cotton wrapped corespun threads
o Superior “union dyeing” because of one-step dyeing process
