Recycling PIN FR PET fibres

Recycling PIN FR PET fibres

Jiuke Chen, Empa Extruded PET (polyethylene terephthalate) fibres neat or with two different phosphorus PIN FRs (DOPO derivate DOPO-PEPA, phosphonate compound) were tested for mechanical recycling, with twin-screw extrusion – quench – spin-melt – reprocessing cycles...
Bio-based intumescent PIN FR coating for NYCO

Bio-based intumescent PIN FR coating for NYCO

Nathalie Vest, Texas A&M University Nylon-cotton fabric (NYCO) was multi-layer coated with phytic acid, chitosan and tannic acid, achieving self-extinguishing with 17% weight added. NYCO is widely used in military uniforms and workwear, but has high flammability...
Polymeric PIN FR for PLA

Polymeric PIN FR for PLA

Marie-Odile Augé, Centrale Lille France A self-polymerising commercial additive was compounded into poly lactic acid (PLA) using a twin-screw extruder operating at 185°C. The flame retardant was is able to polymerise under heating. Screw compounding of 20% loading of...
Bio-derived PIN FRs for cotton

Bio-derived PIN FRs for cotton

Alessandro Beduini, University of Milan Polyamidoamines, synthesised from a bisacrylamide (MBA) and natural amino acids, soaked into cotton, significantly improved fire performance. Nine different α-amino-acids, with hydrophobic, neutral, acidic or basic side-chains,...
