Tent material
— Nylon. Synthetic material with good water resistance and average characteristics in terms of strength and resistance to negative influences: quite main function light weather conditions, however, when wet, it loses some strength (tends to stretch), and is also sensitive to prolonged exposure to ultraviolet radiation. As a result, it is used relatively rarely.
— Polyester. It also refers to synthetic materials, it is considered a slightly more advanced option than nylon: it withstands wetting and heating well, is less sensitive to ultraviolet radiation, and as a result, it has greater durability. At the moment it is the most popular material for awnings.
— Polyamide. The general name for some varieties of synthetic fabrics, including, in particular, nylon and nylon described above. The properties of polyamides are similar to nylon: on the one hand, low cost, resistance to moisture and abrasion, as well as strength, on the other hand, a tendency to stretch when wet and loss of strength when exposed to UV radiation
— Polycotton. A material that combines cotton with synthetic fibers (usually polyester), usually in a ratio of 1:2 (synthetic-cotton). This combination provides durability, resistance to adverse conditions, polycotton resists moisture well and at the same time “breathes”. It's also better than pure synthetics at keeping you cool on a hot day and warm on a cold day. At the same time, this material is quite heavy and expensive, which is...why it is rarely used and only in camping tents (see "Purpose").
— Polyurethane. Typically, this refers to a polyurethane coating applied to a synthetic polyester or nylon backing. The main function of such a coating is to improve the water resistance of the awning (see below). However, the specific values of water resistance in different models can vary markedly. The base material (and, accordingly, the main features of the awning) usually depends on the price category of the tent.
— Polyethylene. Polyethylene is absolutely waterproof, but it also does not let air through. As a result, this material is found exclusively in tents (see "Destination").
— Texit membrane. A variety of high-quality membrane fabrics, combining, on the one hand, high water resistance values (10,000 mm Hg and above), on the other hand, the ability to "breathe" and let water vapor through, which contributes to thermoregulation and maintaining a comfortable climate in the tent. However, this material is expensive, and therefore it is used only in high-end expeditionary equipment.
— Cotton. Natural cotton, usually, with nylon or polyester rip-stop threads, as well as additional water-repellent impregnation. This material is durable, reliable and at the same time passes air well and provides convenient thermoregulation, keeping cool in hot weather and warm in cold weather. Its disadvantages are the high cost and rather large weight, which limits the use of cotton for advanced models of camping tents.
Bottom material
— Polyester. Synthetic material with good durability and waterproof performance. In addition, it is resistant to adverse effects (does not lose strength when wet, exposed to acidic and alkaline environments, temperature changes).
— Nylon. In general, the characteristics of nylon are somewhat lower than those of polyester: it tends to stretch when wet and is generally less resistant to adverse effects. At the same time, given that most owners use tents in relatively simple conditions, these points are not critical; in addition, some manufacturers use a special treatment to improve the durability of nylon.
— Polyethylene. This material is mainly used in inexpensive models of camping tents (see "Purpose") — this is primarily due to its significant weight. For other characteristics, it does not have key differences from other materials.
— Polyamide. The general name for a class of fabrics, which includes, in particular, nylon and nylon. Some manufacturers use this term for marketing purposes: "polyamide" sounds more solid than "nylon", although these materials practically do not differ in characteristics and are used in the same way — mainly in inexpensive models.
Water resistance of bottom
An indicator that reflects the degree of resistance of the bottom of the tent to moisture. For more information about the features of measuring this indicator, see "Tent waterproofness". Here also note that, for obvious reasons, the bottom, unlike an awning, is practically not subject to rain drops — as a result, the requirements for bottom water resistance are significantly lower. So, fabrics with a water resistance of 3000 mm of water. Art. are considered absolutely waterproof (up to the possibility of putting a tent in a puddle), and higher values usually indicate an increased thickness of the fabric and corresponding strength and wear resistance. Just like with an awning, more waterproof fabrics tend to have a significant amount of weight, so it doesn't always make sense to look for bottoms with maximum water resistance.
Reinforced corners
The corners of the tent are one of the "critical" places: in the unfolded state, they have almost the greatest stress, and the fabric in this place can be torn. To avoid this, many tents are equipped with
reinforced corners. In this case, strength can be increased due to multi-layer sewing, special fabric or additional firmware.
Reinforced knots
Reinforced nodes in the design of the tent take on the resulting stress. So, reinforcements in the places of fastening of the arcs prevent the deformation of the load-bearing elements of the frame and prevent their destruction. Also, a lot of stress falls on the corners and seams of the tent awning when unfolded - the fabric in these places can tear due to high loads. The strength of such knots is increased by multi-layer sewing of the awning, the use of special fabric or additional firmware. A reinforced structure may have another weak point of the tent - attaching the awning to pegs (for example, eyelets). What specific knots are reinforced in the tent, you need to check with the seller of the goods in advance.
