Fire retardant treatment based on intumescent concept for non woven polypropylene for back coating process

In order to perform fire behaviour, an alternative plan to treat the polypropylene non woven consists in back coating the textile with formulation based on binder resin.

The formulation of back coating is based on dispersion of fire retardant system based on intumescent concept.

In this way, the protection of fibre during the combustion is ensuring by intumescent structure. The carbon char issue of degradation of binder resin has clearly 3 functions:
- To trap combustion gas in cells, it involves a decreasing a heat release,
- To limit thermal transfers in the materials: thermal insulation,
- To limit the diffusion of oxygen to the materials.

The setting up the treatment is directly interesting for textile industry. It is an opportunity to propose a fire retardant product based on polyester totally free of halogen. The potential applications cover a large range of fields: carpet, home furniture, automotive equipment, railways.
