core spun thread / core spun polyester sewing thread / core spun sewing thread

Product Description

core spun thread / core spun polyester sewing thread / core spun sewing thread 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. The continuous filament polyester core makes up approximately 65% of the thread construction.

core spun thread / core spun polyester sewing thread / core spun sewing thread 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 corespunthread 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 corespunthreads
o Superior “union dyeing” because of one-step dyeing process
The Cotton wrapper contributes to :
o Superior needle heat resistance
o A “wash-down” stitch appearance
