Among the variety of fabrics found in textile, which is designed to create special costumes. Most often, this material serves to protect the rights not only when performing hazardous work, but also in extreme situations. The extraordinary properties of aramid fabric.aramid fabric

What is it?

For the manufacture of such a material is aramid fiber. This fabric is widespread. It is a polymeric material used as a reinforcing component in the manufacture of workwear.

In Other words, coveralls, bulletproof vests, helmets and other accessories – products made of aramid fabric. They are able to protect from bullets and fire. Such products are not only military and test pilots, but also firefighters, Steelworkers and other representatives of dangerous professions.

A Little history

Aramid fiber was first created by the chemist of the American company DuPont in 1964. Initially, the resulting material was named as Kevlar. Now this is one of the leading brands. Similar material properties were made in the USSR. Its name is SVM – ultra-high-strength material. Some time later came the product Twaron.

Since 1970, the Kevlar fabric was produced on an industrial scale.aramid fiber

Where to use fiber

Aramid fabrics produced in Russia is widespread. Today they are used in many areas. Initially, the Kevlar fabric used:

  1. In the manufacture of tires.
  2. Fiber was part of the heavy-duty ropes and slings.
  3. Material used as a component of composite structures for aerospace and aircraft industry, in the construction of high-speed yachts and cars, durable parts, cameras internal pressure, high speed flywheels, and more.
  4. On the basis of the aramid fabrics has been created bullet proof vests and helmets.
  5. Fiber is also used for sports equipment, household appliances, modeling, and musical instruments.Kevlar fabric

Material Properties

Aramid fabric has unique properties. The molecules of this material are long chain. The majority of amide linkages bonded with several aromatic rings. This is the main advantage of aramid fabric. Because such compounds have a sufficiently large dissociation energy. While aromatic rings provide high levels of thermal stability molecules.

Among the properties of this material is to provide:

  1. High durability. Aramid fabric is able to withstand up to 600 kg per 1 mm2. The strength of this material is higher than that of steel.
  2. High temperature resistance. Aramid fabric, whose properties are unique, does not melt. A breakdown of the fibers starts at a temperature of about 500°C. the Material is able to withstand contact with an open flame within 50 seconds. This fabric does not smolder and ignite. However, its strength at this exposure is significantly reduced.
  3. Low density. Aramid fabric is very lightweight, which makes it simply irreplaceable in the manufacture of workwear.
  4. Low cost. Most sales you can see aramid fiber. The cost of a standard bobbin of such filaments is about $ 20. Length – not less than 3 km away.aramid fabric properties

Fabrics

Aramid fabric has a higher elastic ratio, in contrast to the materials of glass and carbon fibers. To create this canvas can be using conventional weaving equipment. The weave of the fibers can be any. In addition, the finished fabric, if desired, can be painted in any color.

Aramid fabric practically does not tear and does not burn. The material can withstand fire, high temperatures, petroleum products and chemical solvents. Under load, aramid fibers are not deformed. However, the torsional strength is reduced.

As for the cost of a cloth of aramid fiber, it is approximately $ 30 per 1 m2.

Scope fabric

Aramid fabric is used today for the manufacture of:

  1. Protective devices and clothes for metallurgists, welders and firefighters. Due to the unique properties, the canvas protects the skin of workers from exposure to high temperatures, contact with molten metal, sparks, and open flame.
  2. Protection and clothing for the many employees of power structures and military.
  3. Vzryvotehniki tents and other equipment.

The Cost of a suit of this fabric depends on the design and type of material. The price of the cheapest is 250 dollars. However, studies have shown that best protects human costume, which combines layers of plastic and aramid fabric.aramid fabrics of the Russian manufacture

How to care for this fabric

Products made of aramid fabric, if necessary, can be washed. This material does not shrink. However, numerous studies have shown that as a result of repeated washings, exposure to direct sun and UV rays the basic properties of the fabric deteriorate, shebegins to lose its strength.

Experts do not recommend to remove stains from the surface of such material with the help of bleaches, as well as tools designed for chemical cleaning. They degrade the strength of aramid fabrics. This lack deprived of the material which has waterproof coating. In other cases, erasing products made of Kevlar with great caution.
