New flame-retardant polyester high-tenacity yams

摘要

The manufacturer of high-strength polyester filament yarns for technical textiles The Fila-mentFactory (TFF) GmbH, Bad Hersfeld/Ger-many, will introduce a new line of permanent flame-retardant polyester high-tenacity filaments. The flame-retardant properties of the Type 704 FR yarns are achieved by the use of a halogen-free polymer additive. The additive is linked to the polymer by means of both physical and chemical bonds and is thus permanent and non-migrating. The new product line is manufactured according to a newly developed process and allows variable adjustment of phosphor levels depending on the final end-use requirements. TFF is currently the only manufacturer with such a product.
