What's Poly Poly Core Spun® Polyester Sewing Thread ?

In some area it’s alias Poly-Wrapped Poly Core Thread, or Poly Poly Core Spun® sewing thread would be wildly known. The strength of the poly poly core spun® polyester sewing thread depends on the core wire, while the wear resistance and heat resistance depend on the covered yarn. Therefore, the core spun polyester sewing thread is suitable for high-speed sewing, as well as the need for higher sewing firm clothing.

A polyester filament coated with polyester staple fiber during spinning, and then strands of these yarns are combined to make a thread.

Main features and advantages

  • High strength and durability: Its strength is much higher than that of pure cotton or pure polyester staple fibers of the same thickness. Sewing thread is not easy to break, making the stitches very firm.
  • Excellent sewing performance: Smooth and less prone to pilling, twisting, or static electricity on high-speed sewing machines. This greatly improves production efficiency and reduces parking rates.
  • Good heat resistance: In high-speed sewing, the needle will generate high temperatures due to friction. Polyester has a high melting point (about 250-260 ° C), while the cotton sheath can further buffer heat and effectively prevent melting and breakage caused by high temperatures.

Main Features

  • High speed
  • High return
  • Excel in
  • High efficiency

Structure of Core Spun Yarn.

First of all, our poly poly core spun® sewing thread is twisted by 2 or more single yarns which be called ” core spun yarn ” by TFO technical machine.

The mainly performance of strength depends on the core of the core spun yarn, it’s a kind of continuous fibre named filament. This core support high tenacity and low shrinkage speciality of polyester sewing thread. Over the core, there wraped with the short fibre, that makes the yarn has cotton’s looking and smooth touching.

Generally speaking, core spun yarn( thread) combined the advantage both of staple fibre and filament, which becomes more strength and easiliy using.

Application

Poly poly core spun sewing thread has both the high strength of polyester filament sewing thread and the natural fuzz and feel of polyester short fiber sewing thread or cotton thread, making it very suitable for high-speed sewing. To improve production efficiency, many garment companies use high-speed sewing machines that can reach speeds of over 5000 revolutions per minute. Ordinary spun polyester threads cannot withstand high heat or have insufficient tensile strength to break, so the most ideal sewing thread is to use poly poly core spun sewing thread.
