[Hygienic study and evaluation of textile materials with reduced combustibility with reference to the use of the new...

The new anti-flammable preparations, proposed by the Higher Chemical Technology Institute (Sofia), were studied, namely: Pyrofix 2--for treatment of textile materials and Torflam--for production of anti-inflammable polyester fibres. The following parameters were studied: skin-irritating and skin-sensitizing effect of both preparations, skin toxic effect of Pyrofix 2 and migration of chemicals from the anti-inflammable textile materials (from the composition of the preparations used). The results obtained revealed the absence of skin-irritating and skin-sensitizing effect of both preparations and cumulative dermal toxicity of Pyrofix 2. The textile materials with reduced combustibility are chemically stable and do not release compounds in the contact aqueous medium, imitating the underclothes space. Formaldehyde from recipe for the treatment of Pyrofix 2 migrates in the air environment. In conclusion, Pyrofix 2 could be applied for the final anti-inflammable treatment of the textile materials for industrial needs, working garments and everyday textile (with the elimination of formaldehyde compound from the recipe). Torflam could be used in the production of anti-inflammable polyester fibres for textile materials intended for industry and everyday life without immediate contact with the skin of the consumers.
