Making fire retardant textiles halogen free
Halogen free fire retardant properties for textile materials can help in meeting the evolving European fire regulation requirements. The new method involves back coating the textile with a binder resin base. This fire retardant dispersion system is based on the intumescent halogen free concept which ensures fibre protection. The carbon char phenomenon of degradation of binder resin is useful in many ways. It can trap combustion gas in cells thus decreasing heat release. It limits thermal transfers in the materials which aids in thermal insulation and it also limits the diffusion of oxygen to the materials. The use of this treatment is of particular interest to the textile industry. This is because it provides a means to offer a fire retardant product based on polyester that is completely free of halogen. What's more is that the potential applications of this product span an array of fields. These include carpet, home furniture, automotive equipment and railways.
