Whenever you sew for your business or personal use, you want to ensure you have the best thread for your items. Surely you don’t want the thread you used to sew your shirt to come undone, do you? Preventing a catastrophe might be as simple as selecting the right thread for your project.

When sewing for business or personal use, it is important to use the best thread possible. There’s no way you’d want your shirt unraveling because of a poor sewing thread pick. It’s possible to avoid a catastrophe by using the best and most appropriate thread for your particular job.

Learn about and compare Kevlar thread before making a purchase decision. I’ll explain you what each thread’s strengths are, as well as what they’re utilized for. What 40wt implies is something you’ll learn about later on, as are other sewing terms.

What Is Kevlar Thread?

Heavy-duty products like first responder gear and apparel can be made using Kevlar thread. Compared to nylon and polyester thread, its tensile strength is two and a half times greater.

10 Facts About Sewing Thread

For strength and durability, Kevlar thread does not compromise comfort. Even clients who utilize Dupont’s products can rely on their quality.

In terms of ballistic resistance, Kevlar outperforms steel and is more heat resistant. Only a few of the many benefits of this outstanding thread may be cited herein. However, how does it compare to other threads in terms of popularity?

Can Kevlar Thread Be Used for Sewing?

Everyone can stitch with Kevlar thread. Use this thread for ordinary stuff like cords, Goodyear tyres, and great pet toys! This thread has no restrictions on what it can produce.

What Is the Thickness of Kevlar Thread in a Sewing Machine?

The average thickness for Kevlar thread is 1.14mm (0.04 in). It can go up to a size 69 in personal sewing machines, making it perfect for at-home projects with ease. This thread can even be hand-sewn if you need more detailed stitching.

The average thickness for Kevlar thread is 1.14mm (0.04 in). It can go up to a size 69 in personal sewing machines, making it perfect for at-home projects with ease. This thread can even be hand-sewn if you need more detailed stitching.

Thread Types

Polyester Thread

The typical Kevlar thread thickness is 1.14 millimeters (0.04 in). Personal sewing machines can handle up to a size 69, making it ideal for at-home crafts. Because of its fineness, it can also be used for hand-sewing.

Polyester is resistant to mildew, abrasion, and weathering.. Tents, for example, are a better fit for this thread than inside ones.

After a given amount of time, if the polyester thread is not UV-treated, it loses its strength. When working on outdoor projects, choose for UV-treated thread.

Nylon Thread

Furniture, backpacks, leatherwork, purses, and a slew of other items are all made possible thanks to nylon thread. When compared to other threads, the strength-to-size ratio and durability of this one’s are unbeatable. Because of its strength, this thread is ideal for heavy-duty applications.

As a result of its lack of heat resistance, nylon is not recommended for use in applications where temperatures exceed 500°F (260°C). The thread will melt if left out in the sun or in a hot environment for a lengthy period of time.

As a result, it’s important to store any nylon-based crafts in a cool, dry location. To ensure the thread’s longevity, apply a layer of ultraviolet light protection.

Cotton Thread

Quilts, garments, and patchwork can all be made with cotton thread. A natural thread is one that is made from natural materials.

But because it is made of natural fibers, it lacks the same abilities as synthetic fibers. Bugs, mildew, and aging all pose a threat to cotton. You can’t tell if the cotton you bought is high-quality or low-quality.

Kevlar Thread

Strengthening equipment and gear using kevlar thread can be done. In addition to being fire retardant, this thread is twice as strong as nylon, and it is also puncture-resistant. It is safe for first responders to use as well as for regular use. Dupont has this thread in stock.

What is the strongest thread for sewing?

We now know that the strongest stitch we can make is the straight stitch. To ensure a long-lasting outcome, we’ll now look at the second component. A thread.

Upholstery nylon threads are the strongest. The resin coating on upholstery thread increases the thread’s tensile strength. It’s a lab-created substance, as we’ll see later.

The chemistry of nylon is what gives it its superior strength. The molecular linkages between the things are so strong that it’s impossible to separate them. Molecules are large and well-knit. It has a high tensile strength and is difficult to break thread because of it.

Nylon is a polymer, which is a plastic. It’s not a natural product, meaning that you won’t find it in nature. Organic chemicals like coal or petroleum are used to make it. Amazing things happen when you raise the temperature to a very high level.

The Best Heavy-Duty Threads for Strong and Smooth Stitches

Nylon is a polymer, which is a plastic. It’s not a natural product, meaning that you won’t find it in nature. Organic chemicals like coal or petroleum are used to make it. Amazing things happen when you raise the temperature to a very high level.

Selric High Strength Polyester Thread

Polymers are the building blocks of nylon. Because it isn’t a natural substance, it cannot be found in nature. An organic chemical, such as coal or petroleum, is used to make it. Putting it through a rigorous heating and cooling process culminates in a stunning end product.

Singer Clear Nylon Thread

This high-strength, low-stretch monofilament nylon thread is perfect for creating strong, yet undetectable, stitches on fabric. Sewing heavy fabrics like as leather, canvas, and vinyl with this abrasion-resistant thread is a breeze, and it’s also ideal for bead stringing, jewelry assembly, machine quilting, and other creative endeavors.

Gutermann Extra Strong Thread

Colorfast and fade-resistant polyester thread with enhanced strength. Heavy-duty fabrics don’t pull or break this thread’s consistent stitches, and it doesn’t pucker. This soft and elastic thread has a great abrasion resistance, making it ideal for topstitching jeans, repairing fabrics, and sewing leather. Rip-stop nylons and oxford cloth can also benefit from the treatment.

Coats & Clark Inc. Extra Strong Upholstery Thread

It’s no surprise that nylon is a popular thread for sewing upholstery, leather, and vinyl because of its high strength-to-weight ratio. Specially-treated nylon thread reduces friction while sewing at fast speeds, resulting in smooth stitches. Use a size 18 needle and make longer stitches with this thread, which is resistant to weather, abrasion, mildew, and UV rays.

Other strong threads

Threads composed of cotton, as well as nylon, are also highly long-lasting options. On the box for various types of thread you should look at the tensile strength.

In addition to these, the following factors have an impact on cotton thread strength:

  • The type of fiber
  • thickness
  • The cotton’s quality
  • and the process by which it is created

If you don’t plan on stitching a tent, a kite, or furniture, you may be able to get by with a good quality cotton thread. You should be alright if you use a fine thread.

What about stretchy fabric?

Stretchy fabrics make sewing a strong stitch a little more difficult.

When working with flexible fabrics, such as spandex or elastane (commonly known as “Lycra”), we cannot utilize the straight stitch. Stretchy fabrics shouldn’t be sewn with a straight stitch since it causes the thread to rip apart when the fabric is stretched. If you choose a straight stitch, which has no give, you risk removing the fabric’s capacity to stretch completely.

To avoid tearing the thread when the fabric is stretched, we wish to use a zigzag stitch instead of a straight stitch. It is recommended that you use the zigzag stitch because each stitch can cause the fabric to move slightly.

For underwear such as men’s boxers, the triple zigzag is both more stretchy and more durable than the standard zigzag.

Conclusion

Was this article of use to you? Nylon is the strongest sewing thread, according to our answer to the question, “What is the strongest sewing thread?”. Coated or bonded threads, which are among the most durable, are also an option.

High-quality, robust threads are recommended for stitching heavyweight fabrics and long-lasting projects. Feel free to make more comments below if you still have any questions after reading this article.
