Polyester and nylon are both strong options for sewing thread—literally! These durable thread materials are often chosen for their strength, shine and low-lint qualities. However, they are not completely interchangeable, and each has its own advantages and disadvantages. In this post, we’ll explore the main differences between nylon thread and polyester thread and give examples of when to use each.

NYLON THREAD VS POLYESTER THREAD
Before we begin, remember that material is only one factor that affects a thread’s properties. Even threads made from the same material can vary quite a bit. The type, weight, treatments and quality of the thread also play a big role in how well it will work for your project. For more details on different types of sewing thread and how to choose the right one, check out our previous post, WAWAK'S Comprehensive Guide To Sewing Threads.
First, let's take a look at polyester. Polyester thread is an all-arounder: it's strong, a bit flexible, colorfast and often a less expensive option than materials like nylon. It also has some heat tolerance, meaning most polyester threads can tolerate ironing at the appropriate heat settings. For these reasons, polyester is a very popular option for a wide variety of sewing projects. It's very common to see all-purpose threads made of polyester or polyester blends due to the material's versatility. Here are a few key qualities of polyester thread:
Characteristics:
Strong and durable
Some elasticity
Colorfast and comes in a large variety of colors
Water resistant — will dry more quickly than Nylon
UV resistant — choose a UV treated variety if using for an outdoor application
Heat-tolerant
Less expensive
What Is Polyester Thread Used For?
As mentioned, polyester thread is an excellent choice for general use: it's ideal for garments, bags, drapery, crafts and much more. If you're not sure what thread to use for a basic sewing project, a polyester all-purpose thread is usually a safe bet.
Polyester is also ideal for outdoor projects due to its UV and water resistance. This includes items like outdoor furniture, active wear and other items that will be exposed to sunlight or water. For projects intended for extensive sun exposure, such as umbrellas, sails, tents or outdoor gear, UV-resistant outdoor threads like A&E Sunstop offer further protection against fading and degradation.

Nylon thread is generally stronger than polyester, but less versatile. Unlike polyester, nylon thread is not water or UV-resistant, meaning it's not ideal for outdoor use. It's also not as heat-tolerant as polyester and can distort or melt under high temperatures. Where nylon thread shines, however, is in its strength and flexibility. Nylon is generally stronger and more elastic than polyester, making it ideal for heavy-duty or stretch applications.
Characteristics:
• Super Strong and durable — makes it ideal for heavy-use items like upholstery
• Excellent elasticity — options for low to high stretch
• Not Colorfast and comes in fewer colors
• Not Water resistant — will absorb water so it takes longer to dry
• Not UV resistant — not ideal for outdoor applications
• Not heat-tolerant — will distort under high temperatures
• More expensive — still an affordable option
What Is Nylon Thread Used For?
Nylon threads are an excellent option for heavy-duty sewing, like upholstery. Specially-treated nylon bonded threads are extra strong, with a smooth coating that makes them super durable and abrasion-resistant. These threads are great for heavily used items or high-friction sewing applications like upholstery, leather sewing, high-speed sewing, outdoor gear and more. Nylon stretch threads are available for highly elastic materials like activewear, lingerie and stretch fabrics. Transparent monofilament nylon threads, known as invisible thread or blind stitch thread, are also available for subtle hems and other inconspicuous stitching.
NYLON THREAD USES: HEAVY FABRICS, HOME DECOR, ACTIVEWEAR, STRETCH FABRICS, BAGS, GENERAL-PURPOSE (NOT RECOMMENDED FOR PROLONGED OUTDOOR USE)
NYLON VS POLYESTER THREAD FAQS
Frequently Asked Questions
Is Nylon Thread Stronger Than Polyester?
Yes, nylon thread is generally stronger than polyester thread. Nylon has a higher tenacity than polyester, meaning it is stronger relative to its size. In other words, a lighter nylon thread could be as strong as or even stronger than a comparable polyester thread in a heavier weight.
What Is Bonded Nylon Thread?
Bonded nylon thread is a heavy-duty sewing thread with a resin coating that makes it stronger, smoother and more fray-resistant. It's ideal for high-friction sewing applications such as stitching stiff materials like leather and vinyl, or high-speed industrial sewing. It's also an excellent option for items that need to withstand heavy use, such as automotive interiors, upholstery, shoes, carpet and more.
Can You Use Polyester Thread For Quilting?
Yes, you can use polyester thread for quilting. While cotton thread is the traditional choice, many quilters choose polyester thread for its durability, washability and colorfastness.
