2. Let’s take a look at inherently flame
retardant fabrics. Before we get started,
it’s important to note that no fabric is
actually fireproof; given enough time,
they will burn. For example, we all know
that cotton burns easily and rapidly.
However, fabrics like wool and Kevlar
resist flames inherently because of the
structure of the fiber. A tightly woven
wool fabric will take longer to burn than
cotton or linen.

3. Fiber use for flame retardant fabric
 Rayon
 Cotton
 Nylon
 Modacrylic
 Nomex
 Kevlar

4. Types of flame retardant fabrics
There are two main types of flame retardant fabrics; inherent fabrics and
coated fabrics.
 Inherent fabrics: Are woven by using a yarn that has been
scientifically modified to reduce its flammability.
 Coated fabrics: Are retardant because a "topical" treatment is applied
to the reverse of the fabric to reduce flammability. There are a wide
range of FR treated fabrics available but it is important to note that the
treatment will diminish over time and isn't suitable for washing.

5. Factors Influencing The Flame Retardancy
• The thermal or burning behavior of textile fibers
• The influence of fabric structure and garment shape on the burning
behavior
• Selection of non-toxic, smoke-free flame-retardant additives or
finishes
• Design of the protective garment, depending on its usage, with
comfort properties
• The intensity of the ignition source
• The oxygen supply.

6. Functions of flame retardant fabric
•Maintain a barrier to isolate the wearer from the
thermal exposure
•Traps air between the wearer and the barrier to
provide insulation from the exposure
•Reduce burn injury
•Provide escape time
•Does not burn, melt or drip

7. Requirements in FR Product:
• Fire and heat protection.
(Also, if necessary, other Protection properties: High visibility, antacids,
antistatic...)
• Comfort, aesthetics, durability.
(Breathability, strength, abrasion, stable colour fastness, easy care,
weather resistance.)
• Price.
(The cost must be reasonable and according to the different risk
situations. The best solutions at the best price)

8. Flame retardant fabric can be achieved by some methods
• Flame retardant by chemical treatment : PBDEs (polybrominated diphenyl
ethers) , TDCPP known as chlorinated tris, TBBPA (tetrabromobishphenol A) ,
TPHP (triphenyl phosphate), Firemaster 550,
• Flame retardant by heat resistant fibers
• Flame retardant by suitable Structural Engineering

9. Layered Structure
 For the purpose of protection and comfort
 Flame resistant outer shell and
 Thermal liner composed of a moisture barrier Thermal barrier and a
lining material

10. Advantages
• Safe human Body from fire.
• Ensure safety in fire friendly working area.
• Reduce the amount of losses.
Disadvantages
• Less Comfort than other cotton made fabrics.
• More cost than cotton made fabrics
• Need extra care to maintain for long term use
• Not as much fashionable as other fabrics have.
• Very high add on (6-10%) (makes fabric heavy)
• Stiffening of material
• Brittleness and hand loss

11. Application field
• Back coatings for institutional Drapery, Upholstery, Carpets
• Home furniture
• Aircraft /Automotive textiles
• Mattresses and bedding
• Racing suits
• Fire Fighters suits
• Children’s nightwear
• The military

12. CONCLUSION
 Flame retardant fabrics are arranged in the form of several layers,
where each plays its own function of thermal insulation, thermal
barrier and moisture barriers.
 Weight, thickness and structure of the fabric play an important role in
influencing the Moisture Vapor resistance Value and Radiant
Protection.
 The air gap between the skin and fabric play a very important role in
determining the amount of energy transferred to the skin, which is
described using various quantitative models built on different
parameters. The heat transfer takes place through conduction,
convection and radiation (greatest) depending on the air gap distance.
