Can polyester filament thread be used to sew tents?

what kind of thread for leather

When it comes to sewing tents, choosing the right thread is crucial to ensure durability, strength, and longevity. Polyester filament thread is a popular choice for various sewing applications, but can it be used to sew tents? In this article, we will explore the suitability of polyester filament thread for sewing tents, discussing its characteristics, benefits, and considerations to help you make an informed decision.

The vast majority of tents are made out of man-made fabrics, either polyester or nylon based. For family tents, you will typically find Polyester. Nylon is used for lightweight backpacking tents. So the answer is: yes;

Understanding Polyester Filament Thread

Polyester filament thread is a type of thread made from continuous polyester fibers. It is known for its high tensile strength, excellent resistance to abrasion, and durability. Let’s delve into the key characteristics of polyester filament thread:

High Tensile Strength

Polyester filament thread offers exceptional tensile strength, making it capable of withstanding high levels of stress and tension. This strength is crucial for tent construction, as it ensures that the seams can withstand the forces associated with setting up, taking down, and using the tent in various weather conditions.

Resistance to Abrasion

Polyester filament thread is highly resistant to abrasion, which is essential for sewing tents. Tents are often exposed to rough surfaces, constant movement, and friction from the environment. Polyester filament thread’s resistance to abrasion helps maintain the integrity of the stitches, reducing the risk of seam failure and ensuring the longevity of the tent.

Polyester filament

Polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a ball.


  • Polyester filament is divided into three types: POY, DTY, and FDY.
  • DTY – Draw texturing yarn, the fibers are crimped.
  • POY and FDY fibers are straight, and the strength of FDY is better than that of POY.
  • The production cost of FDY is low, and the quality of the finished product is stable, the yarn breakage is less, and the dyeing uniformity is good.

Polyester filament thread

Polyester filament thread is known for its strength, durability, and low shrinkage and stretch. It’s the most common thread for outdoor applications. Compared to nylon thread, polyester thread has superior resistance to UV rays and moisture, but much of its strength is lost after prolonged exposure to sunlight.

  • High strength, good heat resistance, elasticity, wear resistance, low moisture regains, and good insulation performance. Poor staining.
  • Polyester filament thread has a wide range of applications, mainly divided into civil and industrial use:
  • Polyester is used as a clothing fiber, and its fabrics are wrinkle-free and iron-free after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., and is widely used in various clothing and decorative materials.
  • Polyester can be used for conveyor belts, tents, canvas, cables, fishing nets, etc. in industry, especially polyester cords used for tires, which are close to nylon in performance.
  • Polyester can also be used for electrical insulating materials, acid-resistant filter cloth, medical industrial cloth, etc. Synthetic fibers have been widely used in various fields of the national economy due to their high strength, wear resistance, acid resistance, alkali resistance, high-temperature resistance, light weight, warmth, good electrical insulation, and no fear of mildew.

Benefits of Polyester Filament Thread for Sewing Tents

Polyester filament thread offers several benefits that make it suitable for sewing tents. Let’s explore these advantages in detail:

Durability and Longevity

Polyester filament thread is renowned for its durability and long-lasting performance. When used to sew tents, it can withstand the rigors of outdoor use, exposure to UV rays, moisture, and temperature fluctuations. This durability ensures that the stitches remain intact, contributing to the overall longevity of the tent.

Resistance to Moisture and Mold

Tents are often exposed to moisture, whether from rain, dew, or humidity. Polyester filament thread has inherent moisture resistance, which helps prevent water absorption and reduces the risk of mold or mildew formation. This feature is particularly important for maintaining a dry and hygienic environment inside the tent.


Polyester filament thread is known for its excellent colorfastness, meaning it retains its color vibrancy even when exposed to sunlight or frequent washing. This is advantageous for tents, as the thread’s color remains intact over time, contributing to the tent’s aesthetic appeal.

Wide Range of Colors

Polyester filament thread is available in a wide range of colors, allowing for customization and coordination with the tent fabric. Whether you prefer a subtle blend or a vibrant contrast, polyester filament thread offers versatility in color choices, enhancing the visual appeal of your tent.

The key benefits of using polyester filament thread for sewing tents

  • High tensile strength for withstanding stress and tension.
  • Excellent resistance to abrasion, ensuring seam integrity.
  • Durability and longevity in outdoor conditions.
  • Moisture resistance, reducing the risk of mold and mildew.
  • Colorfastness for vibrant and long-lasting thread color.
  • Wide range of color options for customization.

Two Considerations for Sewing Tents with Polyester Filament Thread

While polyester filament thread is generally suitable for sewing tents, it is essential to consider a few factors:

  • Needle and Stitch Selection:To ensure optimal performance, select the appropriate needle and stitch type for sewing tents with polyester filament thread. Consider the tent fabric thickness, construction, and the desired seam strength. Using a suitable needle size and stitch type will contribute to the overall strength and functionality of the tent.
  • Seam Sealing:To enhance the tent’s water resistance, it is advisable to apply seam sealer or waterproofing treatment to the seams. This additional step helps prevent water penetration through the stitch holes, ensuring the tent remains watertight during rainy conditions.
