 * Core Detailed Product Description * 

1.What is core spun thread?

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

Core spun  thread Vs Spun Polyester Yarn

 1).Evenness of yarn/polyester wrapped polyester core spun thread

2)Strength. core spun thread  Vs Spun Polyester Yarn 

 

 

 4.The stype of core spun thread /polyester wrapped polyester core spun thread

cotton poly core spun thread and poly poly core spun thread:

 

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
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
