As the title suggests, we’re talking fabrics today.

To be more particular, we’ve two of the toughest fibers out there; rounded up for a head to head comparison.

In addition, we’ll talk about their definitions as well.

Without further ado, let’s take a look at these fibers and where exactly they differ.

600D Polyester

Also known as the “pack cloth”, this fiber happens to be one of the most commonly used fabric in this post cotton era. This is usually used in manufacturing different kinds of backpacks, school bags for kids, and even camping chairs. Moreover, this fiber also happens to be more common than Nylon.

With that being said, 600D is probably the most utilized fabric for manufacturing bags. There are several reasons that make the 600D polyester more popular a choice for manufacturers.

Some of the pros of this fiber are:

  • Come at relatively affordable prices
  • Suitable for use in top quality bags
  • Very durable and have a considerable thickness
  • Abrasion-resistant

1000D Nylon

The 1000D nylon is a fabric very similar to Codura. This nylon also happens to be one of the toughest fibers out there.

This type of nylon comes from the ballistic nylon which was developed as a protective fiber for WWII soldiers. While it didn’t do that much of a good job with deflecting bullets, the world moved on to Kevlar. Nevertheless, this is incredibly durable, water resistant, and easier to work with.

This happens to be the manufacturer’s top choice for specific purposes such as manufacturing military grade backpacks, tactical belts and camping essentials.

The pros of this fiber that make it so desirable in certain fields are:

  • Cheap to procure
  • Easy to work with
  • Very durable and strong fiber
  • Water resistant
  • Proven to be resistant to even the most extreme of weathers
  • Abrasion-resistant

The Differences Explained of 600D Polyester vs. 1000D Nylon

Yes, in case you’re wondering these two fibers seem to be very much alike in terms of properties and uses. However, there are certain areas where these two fibers differ. They are briefly explained below:

Materials They Are Produced From

The 600D polyester is made of polyester whose chemical name is Polyamide. The individual fibers are dried and spun in a mechanical manner, after initially being created as a liquid.

The Polyamide is usually made from petroleum. On the other hand, the 1000D nylon is made of nylon fibers with the chemical name Polyethylene Naphthalate. The chemical solution is spun into the threads of this fiber. The polymer is produced from coal, air, water, petroleum products.


The D in 600D polyester or 1000D nylon stands for Denier. You will be surprised to know that the Denier happens to be the unit of measuring yarn thickness.

In this system the higher the Denier counts, the thicker the yarn is. So 600D polyester is half as thick as 1000D nylon.

To be a bit more precise, 600D means that 600 grams of the yarn will have a length of 9000 meters. Again, 1000D means that 1000 grams of the yarn will have a length of 9000 meters.

Fiber Strength

Even though both the fibers happen to be relatively very strong fibers, the 1000D nylon is exceptionally strong, even more than the 600D polyester.

Moisture absorbency

Although both the fibers have high moisture absorbency, the Nylon has relatively lower absorbency than the polyester fiber.


The differences between the 600D polyester and the 1000D nylon sets them apart in their usage also. The 600D polyester is a top choice among manufacturers for making backpacks, school bags, carpets, camping, and other industrial products.

On the other hand, the 1000D nylon, which happens to be more rugged, strong and resistant to extreme weather conditions is used to make a military-grade backpack, camping materials, tents, and carpets.

The 600D polyester is a preferred choice when it comes to day to day commodities since it’s a durable fiber, comes in colors and even cheaper than its nylon or codura contemporaries.


All that being said, the 600D polyester and the 1000D nylon both happen to be two of the strongest, widely used and versatile fibers out there.

In spite of the similarities in a lot of aspects, the differentiating characteristics of each of these fibers pretty much set them apart in terms of use and happen to be popular choices in their respective fields.
