Flame resistant polypropylene fibres

Results of research into the reduction of polypropylene fibres' (PP) flamma bility are discussed in this paper. Commercial flame retardant additives we re used for reduction of PP fibres' flammability. Fibre resistance against light action as well as resistance to additive washing were studied. A limi ted oxygen index was used for determination of fibre flammability. The elab oration of a technology of two new flame resistant fibre assortments, such as fibre-grade tapes and filaments, as well as their industrial implementat ion at the STRADOM S.A, mill were practical results of our research.
