It is very important to notice that the fire behaviour of complete materials (complex made of foams + textile covering) have no relation with the fire behaviour of component, if taken individually. For example, the following figure present the Rate of Heat Release of polyurethane foam, the one of fire retardant textile polyester structure and the one of the two elements bounded. It is clear that textile structure is not able to protect the foam, as the curve of the complex tends to be similar to the foam to be protected.
In order to achieve the criteria of the new standards, it is mandatory for upholstery fabrics to offer a much higher level of fire protection than what had to be fulfilled up to now. The standard flame retardant polyester fibres and certainly the existing flame retardant PP fibres (using halogen based flame retardants) will not be able to fulfil all these requirements.

Even the flame retardant back-coatings used today need to be dramatically improved  to prevent the ignition of  the foam underneath the fabric . The new material must have two main functions:
       • fire retardant properties: decrease the ignition time (not easy to ignite the materials)
         • flame resistant properties: able to stop the propagation of flame, after ignition
Currently, there is no textile product able in the same time, to achieve these two properties.
