Protos Fil
Fire retardant sewing thread made from 100% para-aramid continuous filament
This thread offers excellent thermal resistance and protective seam durability in applications exposed to high external heat. Para aramid filament is very difficult to dye, but Coats® has developed a unique and innovative dyeing process to offer Protos™ Fil in a range of colours suitable for the mattress industry.
Protos™ Fil meets both American Fed 16 CFR 1633 Mattress Burn Test and Military AA 55220 specification requirements. A special coating is applied to the fibre in order to maximise sewing performance even in the most exacting operations.
