Flame retardant and fire proof yarn and fibers with Swicofil, expert in yarn and fiber specialities
Swicofil has various possibilities and solutions in regard of FR products. This includes different materials as well as various ways of flame retardancy / proof as for example the novelty "spundyed PET high tenacity FR". This spundyed PET high tenacity FR yarn is thanks to a new additive so special, as this additive prevents losses in tenacity from happening, therefore combining the advantages  of a PET ht yarn, a PET FR yarn and a PET spundyed yarn all in one together.

Flame retardant and flame proof characteristics are typically added to industrial and consumer products to meet flammability standards for furniture, electronics, and building products like insulation. This also holds true for textiles. If for upholstery, fire fighter clothing or curtains, inherent and permanent flame inhibiting properties are there to provide safety, one of the paramount concerns of our society.

Flame retardancy (FR) in textiles can be meet via various ways:
  • additive
    the flame retardant substance, also called masterbatch, is mixed into the polymer before the spinning/extusion process
  • inherent
    the material itself is flame retardant / flame proof
  • coating
    the yarn or the textile are coated with a FR layer (e.g. TPU) after they finished production

Flame retardancy for plastics is usually measured in the LOI, the so called limiting oxygen index. The LOI describes the minimum concentration of oxygen, expressed as a percentage, that will support combustion of the polymer. The higher the LOI, the better the flame retardancy, whereas the crucial lower LOI for FR is higher than 21%. This due to the air normally consisting out of 21% oxygen, the most important substance in any combustion process.

Typical yarns that are either inherent flame retardant or become FR by additives or coatings are polyester, PTFE or glass fiber. But also specialities like stainless steel yarns or ceramic yarns form part of FR yarns.
