Canvas suitable for tents
Half-linen canvas (tarpaulin) is a natural heavy fabric, which consists of a harsh thick yarn of cotton and linen. This material is ideal for different types of canvas tents: large military tents, camping hiking tents, summer marquees or winter tents for long-term living in field conditions. The canvas can be treated with different chemicals depending on the requirements of the finished product. Usually, the canvas is treated with anti-rot, waterproof or fireproof chemicals. It has a light olive green colour (beige if the fabric isn’t dyed). To produce high quality tents, the weight of the canvas must be at least 550 g/m² of fabric. In accordance with Russian state standards (GOST), the best canvas for tents is item number 11252СКПВ. Canvas tents made from this material protect against precipitation and heat, do not crack in the cold, do not tear in strong gusts of wind and do not rot in their packaging while waiting for the next camping season.
The advantages of Russian canvas compared to foreign equivalents
Currently, we only export canvas tents (to central and northern Europe, neighbouring countries and Africa). They are universal and popular with customers from all over the world thanks to the canvas’s special composition. Half-linen canvas is only produced in Russia. Its fibres are made from the stem of the annual grass, flax. The tent fabric is very strong, durable and resistant to sunlight; the canvas does not become deformed when stretched (this is important for frameless tents like the USB-56) . Foreign equivalents, consisting of 100% cotton or cotton with the addition of polyester are damaged by the aggressive impact of ultraviolet radiation over 3 to 6 months. Such second-rate tents are usually produced in Pakistan, India or China. They have a shorter service life, they fade and tear; the guarantee period for these cotton canvas tents does not exceed three months.
The advantage of canvas tents in summer
Half-linen canvas is a natural fabric with breathable properties; it remains breathable despite additional chemical treatments. Such a fabric is needed for the production of some tents, for example Pamir Deluxe tents. At high temperatures, the air in the canvas tent is not stuffy as it has natural ventilation and carbon dioxide evaporates through the canvas fibres, making air conditioning unnecessary.
Making tents from waterproof fabric does not guarantee their impermeability. Moisture can seep inside through technical holes, for example textile seams. This can corrode elements of the metal frame, damage the appearance of the inner tent (the fabric will be coloured by rust) and the fabric will rot. To stop water entering the tent through the seams, special waterproof thread should be used. Linen yarn has the ability to swell when it absorbs water and is very hygroscopic. When it starts to rain, this thread gets wet at first (the seam leaks a little), then the holes created during sewing are filled with the swollen linen and moisture no longer penetrates the seam. If you are not sure which thread was used in the tent you want to buy, you should choose a tent with a PVC roof and canvas walls, such as the Headquarters tent.
The importance of canvas in single-layer tents
A single-layer tent is cheaper, doesn’t take up much space in your car and is easier to carry and assemble. If you require a single-layer tent (without insulation walls or an inner tent), have a look at canvas tents (conical Scandinavian tents). Canvas is vapour permeable, which means that condensation will not form in the tent. To avoid dampness in a single-layer tent, make sure you buy a tent made from vapour permeable fabric. Canvas can also be used to sew industrial curtains, canopies and covers, as the equipment that they cover will not get damp and will not corrode from rain or condensation.
Universal fabric for winter frosts
Canvas tents are the best option in harsh winters, when the thermometer drops below -30°C. This is especially true when you need to pitch your tent in the bitter cold, when your temporary accommodation has been in the cold for a long time and the components have frozen. To assemble winter tents, it is vital that the tent remains elastic, otherwise cracks will form in the fabric and the material will be damaged. Canvas remains «soft» at low temperatures, but in such conditions a canvas tent should be equipped with a heating device (a stove or fan heater) to heat up the air, and the inner tent should have insulating walls (to retain heat and create a microclimate inside the tent).
