Noflan - a new flame-retardant for wool
The market for flame retardants (FRs) suitable for public area wool seating has until recently been dominated by Zirpor, a flame-retardant developed by IWS in the early 1970s. These are based on the exhaustion of negatively charged titanium and zirconium complexes on the positively charged wool fibres in acid conditions, during or after dyeing. The Zirpor treatments act in the solid phase, by producing a protective char around the fibres. There is now a modern alternative called Noflan, a new FR for wool. This organophosphorous compound (OP) based on the ammonium salt of an amidoalkylophosphonic acid was developed in Russia and subsequently by Firestop Chemicals Ltd (UK). It is a patented flame-retardant process that imparts flame-resistance to wool by enhanced charring in the solid phase. Noflan has already been EINECS certified. Advantages of Noflan FR treatment: - can be applied by the continuous pad-dry technique, - enhanced FR performance and charring when compared with Zirpor, environmentally responsible chemical with low eco-toxicity, - no problems with batch treatment effluent, wool carpets could be treated by the spray-dry-cure. Limitations are: Noflan cannot be applied by exhaustion; loose stock, top or yarn treatment is not viable. Evaluations indicate that the following special finishes can be combined with the Noflan FR treatment by a suitable sequence of finishes: - natural stretch wool seat covers, - stain-blocked seat covers, - aromatherapy.
