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

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

The formulation of padding is based on dispersion of fire retardant system based on untumescent concept.

A low pick up rate, allows to maintain the softness of textiles. The padding process is adequate for non woven and woven with low density.

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 polypropylene totally free of halogen. The potential applications cover a large range of fields: carpet, home furniture, automotive equipment, railways.
