The INTIMIRE project targets the production of new fire retardant and flame resistant polyester (PET) and polypropylene (PP) fibres, films and upholstery end products based on the original intumescent flame retardancy concept. These products will offer a technical solution to the evolution in requirements defined in upcoming European norms for upholstered furniture and railway transportation. They also must offer improved durability and thermomechanical properties.

2° Needs of the SMES and sectors
   2.1° Furniture sector
The current approaches in developing flame retardant upholstery fabrics are no longer sufficient when novel requirements need to be fulfilled such as:
   · an exclusive use of fabrics with a low rate of heat release
   · an avoidance of the use of fabrics that spread the fire to other elements with burning droplets.
   · a use of fabrics able to prevent ignition of the underneath layers (foam, or stuffing) even at intense flames
     (e.g. in railway application against vandalism using flames).

1° Context
INTIMIRE’s first motivation is to address specific problems faced by European SMEs textile industries. They are connected with the evolution in the strict EC regulations and standards for fire retardant products:
          · the regulations for materials used in railway transportation: ST EN 45545
          · the novel standards of upholstered furniture: norm NF D 60-13
None of the textile products available today, achieves the following points: the criteria of new norms, the environment preservation and the requirement of consumer (comfort, price, design, …).
