Tarpaulin fabric: main varieties, markings.

Tarpaulin (tarpaulin) fabric: we will give a full description of the material - we will talk about the composition, look at it in different photos, talk about density and properties.

Until recently, tarpaulin fabric, which is not afraid of either water or fire, was the only material that could be used in bad weather conditions. And it is still widely used in the military industry, in the production of travel equipment, ammunition for firefighters, rescuers, etc.

On the site you can find other interesting information and descriptions of all types of woven fabrics.

Characteristics, description and composition

Canvas fabric as in the photo is a natural plain weave material based on cotton, flax or jute. Thick twisted fibers are used for production, which explains its high density. Real tarpaulin is made from mixed cotton and linen fibers and coated with a special water-repellent and fire-resistant impregnation. These are two different types of tarpaulin material that have their own purpose. Tarpaulin fabric has a natural composition with different ratios of linen or jute and cotton threads and the addition of synthetics.

We think you will be interested in reading about Cordura material - they have similar characteristics.

Characteristics and properties:

• tarpaulin fabric density – 300-600 g/m2;
• moisture resistance;
• windproof and dirt-repellent properties;
• strength, tear resistance;
• ability for air exchange;
• environmental friendliness;
• wear resistance.

What is tarpaulin made of?

Before talking about the properties of the material, let's figure out what tarpaulin is made of. This is a woven fabric for which natural coarse fibers are used as raw materials. The basis of the canvases can be cotton, linen, jute fiber, but more often - a mixture of these raw materials. Today, synthetic thread is sometimes added to the composition to lighten the weight of the finished material. However, this has a limited scope of application, since it has less fire resistance.

Depending on what the tarpaulin is made of, it receives texture and density. The most textured fabrics made from jute fiber. If the composition is linen and cotton, the material is smooth. Since it is woven, it allows water to pass through. To give it the required properties - fire resistance or resistance to water, the canvas is treated with a special impregnation.

Regardless of the composition, the properties of different types of tarpaulins are as follows:

• high fabric density;
• weight – from 300 to 900 grams per square meter;
• resistance to moisture and rot;
• resistance to microorganisms;
• frost resistance.

There is no concept of UV resistance for tarps. Natural fibers, unlike polyethylene and polypropylene, do not decompose when exposed to sunlight. The exception is canvases with polymer impregnation: only the top layer is subject to decomposition, while the base (tarpaulin fabric) does not deteriorate under the sun and retains its original strength.

Advantages and disadvantages

Advantages:

• natural composition;
• mechanical tensile strength;
• protection from wind and rain;
• fibers are not destroyed by rot and fungi;
• resistance to high temperatures;
• availability.

The disadvantages of tarpaulin include the fact that, as a result of its high density, thickness and rigidity, clothing and equipment made from it are quite heavy, which makes them not very convenient for movement.

Types of tarpaulin

The composition determines the properties of the material. Depending on the processing technique, the following types of tarpaulin are distinguished.

Refractory. It is impregnated with a polymer composition, which makes the canvas resistant to open fire. The color of such canopies is brown or brownish-yellow. High-quality material can withstand contact with fire for 90 seconds. None of the synthetic fabrics in a similar price category are capable of this. Does the tarp burn? No, if you expose it to fire for a long time, the threads will begin to break down and holes will appear on the canvas. But it is not capable of ignition, since it is a self-extinguishing material.

Fire-resistant tarpaulin with a density of 480 g/m2, treated with impregnation at the rate of 40 g/m2, is widely used. Its fire resistance time is 50 seconds.

Water resistant. To make the canvas waterproof, it is impregnated with SKVP. This impregnation creates a water-repellent layer on the surface of the canvas with a degree of water resistance up to 3000 mm water column. It also has light resistance, that is, its structure uses light stabilizers that do not allow the polymer to degrade in the sun. It also improves the anti-rot properties of canvases, increasing their resistance to moisture with regular contact with it.

Waterproof tarpaulins with a density of 450 g/m2 are in demand on the market; the impregnation volume is 40 g/m2.

Interesting

Another name for tarpaulin fabric is “canvas”. It comes from the Dutch word “pressening” and is translated as “shell”. Due to the rapid development of the navy, starting from the 15th century, this waterproof canvas material began to be widely used in the manufacture of sails.

What is canvas fabric

Increased strength and technical characteristics that are many times superior to analogues made from synthetic materials: tarpaulin is a fabric for which, despite the development of the polymer industry, they have not been able to find an equivalent replacement. It is massive, dense, tear-resistant, durable. And for a number of industries these features are preferable.

Traditionally it is called canvas, since the canvas was originally used to make sails. Canvas is highly resistant to rotting and serves in adverse weather conditions, exposed to sea spray, rain, salt air and winds for years. Today, the material is used in other areas: canvas has become a thing of the past, while tarpaulin is in demand in construction, manufacturing, cargo transportation, and is indispensable in the manufacture of workwear and shelters.

In which industries is it used?

Tarpaulin canopies developed in accordance with GOST are used in many sectors of human activity. At the time of its creation, canvas was used mainly in shipbuilding, but over time, tarpaulin spread to:

• Production of specialized clothing - suits, mittens, raincoats for construction workers. Tarpaulin is actively used in the creation of protective clothing for fire-fighting welders and metallurgists due to its ability to withstand the effects of fire, sparks, etc.
• Agricultural sectors - tarpaulin canopies are actively used to cover agricultural crops. Office vehicles are stored under them and equipment is protected from corrosion, since the awning will not allow moisture to pass through. Another application in agriculture is that a tarpaulin canopy is suitable for covering crops.
• In construction, tarpaulin is used in the construction of temporary canopies; building materials and buildings are stored under tarpaulin canopies with eyelets, completely protecting them from the negative effects of the environment. In addition, the material is actively used in the construction of fences, slopes, and formwork when heating concrete joints.
• In military affairs, the production of canvas awnings began during the Second World War. In those days, canvas replaced leather, which was too expensive during military operations. Belts, belts, and boots for soldiers were made from tarpaulin.

Now tarpaulin is used by fishermen, hunting enthusiasts, summer residents and motorists. Tents, backpacks, canvas for covering supplies, chairs for tourism, etc. are made from it. Most of the elements of ammunition continue to be made from canvas. Every item made from it is durable, practical and does not require special care.

In you can purchase tarpaulins of Russian and foreign production. All materials are made from the highest quality raw materials and have passed appropriate tests. If necessary, our managers will advise you and select the best tarpaulin awnings for your garden, home or travel.

Description of semi-linen canvas (tarpaulin)

Close-up photo of tarpaulin

Semi-linen canvas, or as it is more often called, tarpaulin, is used in many areas of life, in construction, in production, in the army, etc., the list is huge. Many people have probably encountered this fabric in one way or another. In this article we will tell you what types of tarpaulin there are

, what characteristics it has, how it differs, what it is used for. I would like to note right away that not all possible ways of using tarpaulins will be described here, but only those that I know about.

Tarpaulin impregnation

First, let's talk about canvas impregnations. Here are the types of tarpaulin impregnations:

• OP - Fireproof Impregnation, indicates that the tarpaulin has a certain resistance to fire, depending on the article - 35 or 50 seconds. (if the tarpaulin complies with GOST 15530-93), if the tarpaulin is produced according to the manufacturer’s specifications, then this parameter may differ. Further, all values ​​will be indicated for tarpaulins manufactured in accordance with GOST 15530-93.
• VO - Water-repellent impregnation, with such impregnation the tarpaulin must withstand up to 100 mm of water column.
• SKPV - Light-resistant Combined High Water Resistance, withstands from 125 mm to 250 mm depending on the article.
• SCOP - Light-resistant Combined with Increased Fire Resistance, fire resistance for more than 50 seconds.

Using canvas curtains to protect premises during the cold season

During the cold season, curtains made of tarpaulin are often placed in the windows and openings of warehouses or other utility rooms. The Tarpaulin curtain is an inexpensive option for industrial curtains that have a high density. It allows you to protect the interior from the penetration of cold air and drafts, and also perfectly retains heat inside the building.

The Tarpaulin curtain is impregnated with a special water-repellent composition and is slightly airtight. Thanks to the high density of interwoven threads and special impregnations, such a tarpaulin does not allow moisture to pass into the room even during heavy rainfall.

Tarpaulin curtains can also have fire-fighting properties when using fire-resistant impregnation. Due to their high wear resistance, such curtains can be used for several seasons. To hang curtains on a beam or hook, metal eyelets are placed along one edge of the panel. The bottom edge of the curtains is hemmed using lavsan threads. This allows you to strengthen the edge and make the entire product more neat.

Tarpaulin products are widely used for insulation of warehouses, industrial workshops, transport terminals, and garages. Also, tarpaulin curtains are often placed in gazebos and open verandas. In this case, they are the best alternative to glazing, as they are low cost and very easy to install.
