Nylon is a popular material in many outdoor and indoor products because of its durability, versatility, and resistance to wear and tear. One of the most common questions that outdoor enthusiasts ask is what the difference is between 210T and 210D nylon. In this blog post, we'll answer that question and more.
What does 210T nylon mean?
The world of fabrics can be confusing, especially when it comes to deciphering the various codes and measurements used to describe them.
When you search the web for the meaning of 210T nylon, you'll likely come across different interpretations.
Some sources claim that the "T" in 210T stands for "Taffeta", while others suggest it stands for "Tex".
However, after conducting extensive research and consulting numerous fabric suppliers, the prevailing consensus is that the "T" in 210T stands for Thread Count.
In another word, its serves as a measure of density, indicating the number of threads closely woven together in a square inch.
In the context of 210T nylon, it means that there are precisely 210 threads or yarns per square inch of fabric. This count includes both the warp (lengthwise) and weft (crosswise) threads within the designated fabric area.
What does 210D nylon mean?
210D nylon is lightweight fabric that is often seen in bags, backpacks, and outdoor gear.
The "D" in 210D nylon refers to Denier, which is the unit of measurement used to describe the thickness of yarn. It is the mass in grams per 9000 meters of the yarn.
In the case of 210D nylon, it means each yarn weighs 210 grams per 9000 meters.
210D vs 210T?
When it comes to fabrics, there are two common ways to describe them: by Denier and Thread Count. However, these two measures are not comparable since they represent different aspects of the fabric.
Denier measures the thickness of yarn used in the fabric, while Thread Count measures the number of woven threads per square inch of fabric.
To clarify the differences between 210D and 210T fabrics, we have contacted some fabric suppliers to find out the typical Denier and Thread Count for 210D and 210T fabrics. Here's what we have learned:
For 210D fabrics, the Denier is obviously 210, and the Thread Count commonly ranges between 100T to 135T.
For 210T fabrics, the Thread Count is 210, and the Denier commonly ranges between 60D, 63D, 66D and 75D.
Apparently, 210D and 210T fabrics can be very different in terms of Denier and Thread Count. The former has much thicker yarn (about three times as thick), while the latter has double the density of its counterpart. To make the fabrics more comparable, we suggest naming them more completely by including both their denier and thread count, such as "210D 100T Nylon" and "75D 210T Nylon."
The photo below shows a close-up comparison of a typical piece of 210D fabric with a typical piece of 210T fabric. As you can see, the two pieces are very different from each other.
Is 210T waterproof?
It depends on the surface treatment and coating. For instance, 210T nylon is usually not waterproof, but water-resistant—meaning that it will eventually soak through. However, 210T nylon can still be a good choice for products that require breathability if those are your priorities.
Is 210T better than 210D?
The main differences between 210T and 210D nylons are in their yarn thickness and density.
210D nylon has a thicker and more durable yarn, making it more resistant to abrasion and more sturdy overall. Therefore, 210D nylon is a better option for products that require durability and strength, such as backpacks and luggage.
In contrast, 210T is a light-weight and high-density fabric. With proper surface treatment and coating, it is ideal for use in tents and other outdoor apparel such as lightweight jackets, windbreakers, raincoats and umbrellas.
So, if you want tough and durable products, 210D nylon is the way to go, while 210T nylon works better for lightweight and outdoor items.
What are fabric coatings?
Fabric coatings are applied to fabrics to make them more resistant to water, dirt, and stains. Depending on the type of coating, they can also improve the fabric's strength and durability.
What is a Polyurethane (PU) coating?
Polyurethane coating is a common type of coating applied to nylon fabrics to waterproof them. It is a thin layer of polyurethane that is applied to the fabric's interior or exterior. This makes the fabric more durable and water-resistant.
What are C8, C6, and C0?
C8, C6, and C0 are types of durable water repellent (DWR) coatings. These coatings are usually applied to fabric to make them water-resistant. The numbers represent the number of carbon atoms in the DWR, with C8 being the most effective and most toxic. C6 is less effective than C8 but is still effective against water. C0 is a more environmentally friendly option that is not as effective as the other two options but still provides some level of water resistance.
In conclusion, when choosing between 210T and 210D nylon, the decision should be based on the specific needs of the product. If durability and strength are required, go with 210D. If you are looking for a lightweight and smooth fabric, 210T is a great option. Remember, when it comes to nylon and fabric coatings, there is no one-size-fits-all solution, and it is always best to consult a professional before making a purchase.
