*Detailed Product Description * 

1.What are polyster wrapped polyster Core spun Yarns?

Core spun, or “poly core”, yarn is created by twisting staple fibers around a central filament core, usually made of polyester for extra strength.

It is 40% to 50% stronger than normally spun yarn of the same weight, and reduces the number of broken stitches when sewing seams and hems on denim.

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

2.The polyster wrpped polyster core spun thread’structural drawing:

  1) Our staple fibers is 38MM,it is come from Japan toray brand .

 2)Our long fiber have 50D,75D,100D etc.All oftension strengtht are over 7.3gram per denier

 3.Advantagese shows:

Core Spun Vs Spun Polyester Yarn

1).The dyeing process(core spun yarn VS spun polyster yarn)

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

 2)Strength. Core Spun Vs Spun Polyester Yarn

3).Shrinkage:

 4)The wrapper of a corespun thread can be either staple polyester or staple cotton. T

he 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

5) washing effects

5. Application

 Use for :Jeans,Hand bag,sofa,book binding ,and so on .

1. Use for thread factory
2. Use for book binding
3. Use for cotton qulited products.
