About fire /flame retardant fabrics

  • The regular textile consists of highly flammable materials and turn into primary source of fire percolation in case of break-out. However fabrics is required for visual appeal.
  • Fire retardant fabrics per form both the task of providing aesthetics to the surroundings and preventing spread of fire.
  • The there are typically two major categories of fire retardant fabrics which are coated fabric and inherently fire retardant fabric.

Product characteristics:
 

  • The fire retardant fabrics are primarily of two types:
  • 100% cotton fabric with coating of fire retardant chemical.
  • Inherently fire retardant fabric.
  • The cotton fabrics are coated with fire retardant chemical in a bath which results in a layer of fire retardant getting formed on the cotton surface.
  • The weave and the basis weight of the cotton fabric too decide the performance of this fabric.
  • However, incomplete coverage of fire retardant chemical reduces the performance with wear and tear, cracking, flaking, bending and aging.
  • The other type of fabric is the one which uses inherently fire retardant fibres. These are modified polyester fibre with permanent fire retardant properties. The fibre is obtained after high level of polyester modification. The fabric made from inherently fire retardant fibres results in uniform fire retardant features.
  • The other fibres used for fire retardant fabric are:
  • Meta Aramid
  • Para Aramid
  • Modaacrylic
  • Polyamide
  • Vinal

The typical characteristics of the fire retardant fabric are:

  • Very low fume toxicity in fire
  • High tear and abrasion resistance
  • Breathable and comfortable
  • Anti decay and Anti mould
  • Crease resistance
  • High dimensional stability
  • No fading and excellent color tone

Raw-materials:

1. Coated fire retardant fabric:

  • The base cloth is 100% cotton generally.
  • The strength of the fabric is dictated by the cotton yarn and basis weight of the cotton fabric.
  • By means of higher gram per square meter (GSM) of the fabric, its weight strength loss can be delayed.
  • The cotton fabric of desired weave and basis weight is treated with fire retardant chemicals and a chemical bath and processed further to give the finished fabric.
  • The commercial name of some chemicals used for flame retardant are PYROVATEX® and PYROGUARD®.

2. Inherently fire retardant fabric:

  • The fabric is made from fire retardant fibre like Trevira.
  • The fabric characteristics are decided by the weave and basis weight.
  • The filament yarn used is in the range of 50 – 1350 dtex
