Is Polyester Filament Thread Strong?

Yes, polyester filament thread is known for its strength and durability. Polyester is a synthetic fiber that is commonly used in the production of sewing threads due to its numerous advantageous properties. Here are some reasons why the polyester filament thread is considered strong:


  • Tensile Strength: Withstand a significant amount of stress and tension without breaking. This property makes polyester filament thread suitable for a wide range of sewing applications, from lightweight fabrics to heavy materials.

  • Abrasion Resistance: Resistant to abrasion, meaning it can withstand friction and rubbing without wearing down or breaking. This makes it ideal for sewing projects that involve repeated use or contact with rough surfaces.

  • Chemical Resistance: Resistant to many chemicals, oils, and acids. This property makes it suitable for applications where exposure to chemicals or environmental elements is a concern.

  • Moisture Resistance: Resistance to moisture absorption helps prevent the weakening of the thread when exposed to wet conditions.

  • UV Resistance: Generally resistant to UV radiation from the sun, which means it won't degrade as quickly when exposed to sunlight. This makes it suitable for outdoor applications where exposure to sunlight is a factor.

  • Color Fastness: It retains its color well and doesn't fade easily when exposed to light or washing. This is important for maintaining the appearance of sewn items over time.

  • Low Stretch: Low stretch compared to some other types of thread, which helps maintain the stability of stitches and prevents them from becoming loose over time.

  • Easy Care: Easy to care for. It can withstand machine washing, drying, and ironing without losing its strength or shape.


Due to these properties, polyester filament thread is widely used in a variety of sewing projects, including apparel, home textiles, upholstery, outdoor gear, bags, and more. It's suitable for both lightweight and heavy fabrics, and it can handle various stitching techniques. However, it's important to select the appropriate weight (thickness) of polyester filament thread based on the weight of the fabric and the requirements of your project.
