What Is Kevlar Thread?

Kevlar thread is used to make high-strength items, including as clothing and equipment for first responders. Two and a half times that of nylon and polyester thread, its tensile strength is exceptional.

10 Facts About Sewing Thread

For strength and durability, Kevlar thread does not compromise comfort. Customers that often rely on DuPont products can rest assured in their reliability.

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

A typical Kevlar thread is 1.14mm thick (0.04 in). If you have a home sewing machine, you can use it to create items up to size 69. If more precise stitching is required, this thread can be sewed by hand.

Kevlar thread typically measures 1.14mm in thickness (0.04 in). Personal sewing machines can accommodate it up to size 69, so it’s great for use on smaller projects around the house. If you need to sew something more intricate, you can even use this thread to do it by hand.

Thread Types

Polyester Thread

Polyester is unaffected by mildew, wear, or the elements. Examples of outdoor structures that are more appropriate for this thread include tents.

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

Nylon Thread

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

Over time, polyester thread that has not been UV-treated will weaken. UV-treated thread is the way to go for any outdoor sewing.

As a result, it’s important to store any nylon-based crafts in a cool, dry location. Protecting the thread from the sun will extend its life.

Cotton Thread

Cotton thread can be used for quilting, sewing, and patching. Thread spun from natural fibers is referred to as “natural.”

However, its capabilities are limited in comparison to synthetic materials because it is constructed from organic materials. Cotton is vulnerable to pests, mildew, and the effects of time. You have no way of knowing whether the cotton you purchased is of high or low grade.

Kevlar Thread

Kevlar thread can be used to reinforce tools and gear. This thread is twice as robust as nylon and can withstand punctures without breaking. It can be used by emergency personnel without risk, and it’s also fine for everyday use. This thread is available in stock at Dupont.

Rip-stop nylons and oxford cloth can also benefit from the treatment.

Other strong threads

Strengthened, colorfast polyester thread that won’t fade. When using this thread, even thick materials won’t be able to yank or tear the stitches apart, and the finished product won’t pucker. The high abrasion resistance of this supple, stretchy thread makes it perfect for topstitching denim, mending clothing, and stitching leather. Similarly treated fabrics include rip-stop nylons and oxford cloth.

Additionally, the following also affect cotton thread strength:

  • Which sort of fiber
  • thickness
  • Exceptional quality of the cotton used.
  • and its method of production

It’s possible that you could get away with a good quality cotton thread if you weren’t planning on stitching a tent, a kite, or furniture. If you use a fine thread, you should be OK.

What about stretchy fabric?

Sewing a sturdy stitch onto stretchy textiles presents a minor challenge.

The straight stitch is not suitable for use with stretchy materials like spandex or elastane (also known as “Lycra”). When sewing on stretchy textiles, a straight stitch should be avoided because it can cause the thread to break. If you use a straight stitch, which doesn’t stretch, you can destroy the fabric’s elasticity.
