Understanding the Differences between Filament Sewing Thread and Spun Polyester Thread

When it comes to selecting the right thread for garment construction or other sewing projects, choosing the right thread type is important. Two popular types of threads that are used in sewing are filament and spun polyester threads. In this article, we will discuss the differences between these two thread types, their characteristics, and their ideal use.

Filament and spun polyester sewing threads are two of the most commonly used threads in garment construction and other sewing projects. Understanding their differences is essential in making a wise choice in selecting the appropriate thread type for your specific sewing needs.

What is Filament Sewing Thread?

Filament threads are made using continuous single strands of synthetic fibers. These strands are highly twisted and wound together to form one thread. Filament threads are characterized by their high strength and low linting properties.

Advantages of using filament sewing thread

  • High strength and durability.
  • Low risk of breakage and skipping during sewing.
  • High resistance to abrasion and stress.
  • Good for high-speed machine sewing.

Disadvantages of using filament sewing thread

  • Filament threads are less flexible and tend to be very stiff, making them unsuitable for sewing certain types of fabrics.
  • They may leave visible needle holes or marks on some fabrics due to their stiffness.
  • They are not suitable for high-temperature applications as they have the tendency to melt under heat.

What is Spun Polyester Thread?

Spun polyester threads are made from shorter polyester fibers that are twisted and spun together to create a single strand of thread. These threads are characterized by their softness, flexibility, and low-fuzz properties.

Advantages of using spun polyester thread

  • Softness and flexibility, making them suitable for various fabrics including stretch fabrics.
  • Low risk of leaving visible needle marks as they tend to slide through the fabric with ease.
  • High resistance to sunlight, moisture, and chemicals.
  • Highly versatile and ideal for garment construction and embroidery.

Disadvantages of using spun polyester thread

  • They tend to be less durable and break more easily than filament threads.
  • Not suitable for certain types of technical fabrics as they have the tendency to fray and break.
  • May produce a higher amount of fuzz and lint during sewing.

Comparison between Filament and Spun Polyester Threads

To compare the differences between filament sewing thread and spun polyester thread, we’ve created a comparison table below:

From this comparison, it is clear that filament thread is stronger, more durable, and has high abrasion resistance, making it suitable for heavy-duty sewing whereas the spun polyester thread is more flexible, suitable, and highly adaptable to various fabrics, including stretch fabrics, garment construction, and embroideries.

Deciding on the Right Thread Type

Deciding on the right thread type to use for a specific project largely depends on the type of fabric, the complexity of the project, and the intended use of the final product. If you are working on a project that requires heavy-duty sewing or requires high abrasion resistance and strength, filament sewing thread is a good option. On the other hand, if you are working on a project that requires flexibility, adaptability, and a soft finish, spun polyester thread is preferred.

Conclusion

In conclusion, filament and spun polyester threads are two of the most popular types of threads used in garment construction, embroidery, and various sewing projects. Each thread type has its unique properties and advantages. Determining the right thread type to use depends on various factors such as fabric type, application, and durability expectations. With this guide, you can better understand the differences between these two thread types and make a wise decision about which one to use for your next project.
