It’s a unit of density based on the length FR Tent Fabric and weight of a yarn or fiber. A single strand of silk is considered 1 denier. The fibers in a 40-denier nylon fabric have over times the diameter of the silk strand, and almost 1.5 times the diameter of fibers in a nylon fabric.Often it does, but not always. Strength also depends upon the material. For example, the following tent fabrics are shown in increasing order of strength.WThis measurement refers to the sum of the vertical and horizontal threads or yarns per square inch of fabric. A higher thread count doesn’t always mean a stronger fabric. For instance, our Carbon Reflex and Hubba tent canopies and rainflies which are made of nylon use a high thread count of threads per inch, yet our Elixir rainflies stronger because of their packcloth fabric use only 210 threads per inch.
Use our engineering and design expertise to determine when and where to use different fabrics to serve each tent best for its intended use. For example, we selected higher strength fabric for the hardwearing floors and rainflies in our Hubba series backpacking tents. But when designing our series tents, we chose packcloth for the rainflies. Packcloth, a polyester fabric, is not as light as nylon but is more durable and durability was a top priority for the Elixir tents. Polyester also doesn’t stretch as easily as nylon, making it more user friendly, and it’s naturally more UV and water-resistant.These are just a few of the many factors we consider when selecting fabrics for MSR tents.
The last set of specs in the formula refers to fabric coatings. The first part is the waterproofing rating, a measurement we’ll discuss at length the next post: Understanding Tent Fabrics.Waterproof Fabrics. In short, a fabric’s waterproof rating measures how much water can be sustained on top of the coated fabric in this case, 1200mm before water can leak through. For each MSR tent, we select an ideal level of waterproof coating, which is applied to the interior side of the base fabric, to achieve waterproofness without compromising tear-strength.The second part of the above spec refers to the type of water-resistant coating, such as silicone.
Water which is applied to the exterior side of the tent fabric to cause water from rain or dew to bead up and resist saturating the material. Silicone coating offers some UV resistance and makes the fabric softer, pliable and a little stronger, making it a good choice for rainflies carefully consider how thread count, fabric type and denier fiber thickness will affect the overall tent performance, and we make our decisions based not only on how the tent will be used thru-hiking, weekend backpacking, basecamping, but also on where the fabrics are used in the different parts of the tent. Tent floors, for example, require strong, tear-resistant fabric, while rainflies need to be strong yet also supple.
