What is Polyester Sewing Thread
Polyester is a kind of polymer fiber made by spinning, mostly referring to the fiber produced from ethylene phthalate as raw material, referred to as “PET” fiber.
Sewing machine polyester thread is the thread required for knitted clothing products. Sewing thread can be divided into three categories according to raw materials: natural fiber, synthetic fiber sewing thread, and mixed sewing thread. Sewing thread uses pure polyester fiber as its raw material.

Polyester sewing thread refers to sewing thread produced with polyester as raw material.
Features of Polyester Sewing Thread
Polyester sewing thread is made of polyester long fiber (CF polyester thread) or short fiber twist (Spun polyeter thread), wear resistance, low shrinkage, good chemical stability. However, the melting point is low, and it is easy to melt at high speed, block the needle eye, and easily break the thread. Due to its high strength, good wear resistance, low shrinkage rate, good moisture absorption, and heat resistance, polyester sewing thread is resistant to corrosion, mildew, and insects. It is widely used in garment sewing of cotton fabrics, chemical fibers, and blended fabrics.
In addition, polyester sewing thread also has the characteristics of complete color and luster, good color fastness, no fading, no discoloration, and sun resistance.
Polyester vs Nylon
The difference between polyester sewing thread and nylon sewing thread, polyester ignites a lump, emits black smoke, smells not heavy, and has no elasticity.
Nylon sewing thread ignites a lump, emits white smoke, and has a strong smell when pulled up. Nylon sewing thread has high wear resistance, good light resistance, mildew resistance, coloring degree of about 100 degrees, and low-temperature dyeing.
