Determination of Ignition Properties of Vertical Test Samples
Determination of Ignition Properties of Vertical Test Samples

With the developing technological possibilities of today, four different methods are applied to obtain flammable fabrics:

  • When weaving fabrics, use of flame retardant fibers such as carbon, asbestos or glass
  • Modification of fibers by chemical modification methods
  • Addition of a number of chemical substances to synthetic polymers which allow the ignition of fibers during fiber spinning
  • Treatment of fabrics with some chemical materials

Each of these four methods is widely used in the textile sector. In addition, depending on the area of ​​use of the fabric, these methods can be used alone or together to achieve the best power ignition and combustion behavior. In this way, power flammable fabrics are produced for petrochemicals, aircraft, aerospace, steel industry and other sectors requiring high protection.

During finishing processes, the following chemical elements are generally used: phosphorus, antimony, chlorine, bromine, boron and nitrogen. These elemental compounds have been synthesized to impart strength ignition properties to textile products.

The following standards apply to tests carried out by authorized laboratories to determine the ignition property of vertical test specimens:

  • BS EN ISO 6940 Textile fabrics - Combustion behavior - Determination of ease of ignition of vertically oriented samples
  • TS 5775 EN ISO 6940 Textile fabrics - Combustion properties - Determination of ignition properties of test specimens in vertical position

These standards include a method for determining the flammability of textile products and industrial products consisting of single or multiple components (coated, multilayer, quilted, sandwich structure and the like) in vertical position if exposed to a certain small flame.
