The FilamentFactory in Bad Hersfeld, as a leading manufacturer of polyester filament yarns, has a proven track record of producing flame retardant multifilament yarns. Our FR yarns are the result of continuous product development and our commitment to offer our customers best-in-class products. This next generation of polyester industrial FR yarns combines non-toxic flame retardant performance with low shrinkage and the highest possible tenacity.

First and foremost our FR yarns offer long lasting safety to your products. It helps support shorter burn length and lower flame propagation.
Flame-retardant polyester yarns have historically resulted in lower tenacity values than conventional polyester yarns. Now with tensile values up to 70cN/tex, our FR product line sets a new bench mark in industrial flame-retardant yarns. Combined with extremely low shrinkage values, this next generation fibre is an absolute powerhouse.
The industrial yarn quality makes our FR permanent flame retardant and more durable than textile grade flame-retardant yarns. The flame retardant properties are strongly anchored into the polymer chain. This will guarantee yarn properties throughout your production process and deliver them to your end product.
