What Is UV Resistant Bonded Polyester Sewing Thread,Advantages

Filament Thread

Sewing 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 threads mostly use pure polyester fiber as their raw material.

Polyester is a type of fiber made by spinning polymers, mostly fibers produced from ethylene phthalate. Polyester fiber is a high-quality synthetic fiber. The sewing thread made from it has high strength and good wear resistance.

Polyester sewing thread, also known as high-strength sewing thread, refers to sewing thread produced from polyester as raw material. The polyester sewing thread has high strength and does not lose strength when wet. Its shrinkage rate is small, and the shrinkage is less than 1% after proper shaping, so the sewing stitches can remain flat and beautiful. The stitching and fabric can maintain consistent expansion and contraction without shrinkage.

Characteristics Of Polyester Sewing Thread

Polyester sewing thread is widely used in clothing products, leather products, military supplies and other fields due to its high strength, good wear resistance, no knots, corrosion and mildew resistance and other good properties.

  1. High strength, smooth and beautiful stitches, and good wear resistance;
  2. No mold or rot, rich in color, no shrinkage.
  3. It has good color fastness and light resistance, and is not easy to fade or change color.

What Is UV Resistant Bonded Polyester Sewing Thread

UV resistant bonded polyester thread is engineered with a specialized formula that enhances its ability to withstand prolonged exposure to UV radiation. It combines the inherent strength of polyester with a unique treatment that imparts resistance to the damaging effects of sunlight. This thread serves as a shield, preserving the integrity of stitched seams and ensuring that the final product remains durable and fade-resistant over time.

Advantages of UV Resistant Bonded Polyester Sewing Thread

  1. Longevity: The ability to resist UV radiation translates into prolonged durability, making this thread type an ideal choice for outdoor applications.
  2. Color Retention: UV resistant bonded polyester thread maintains its vibrant colors, even when subjected to the sun’s rays. This feature ensures that the final product remains visually appealing.
  3. Strength and Performance: The inherent strength of polyester combined with UV resistance ensures that stitches remain secure, withstanding the stresses of various applications.
  4. Versatility: UV resistant bonded polyester thread is suitable for a wide range of sewing projects, making it a versatile option for both indoor and outdoor applications.


UV resistant bonded polyester thread stands as a testament to the harmonious fusion of innovation and functionality. As the sun’s UV rays pose a significant challenge to the endurance of stitched products, this thread type emerges as a dependable safeguard against fading, weakening, and degradation.
