The study of flame retardancy and thermal properties of seacell fabrics

Abstract

In this study, the properties of flame retardant woven fabrics produced from the SeaCellactive and SeaCellpure yarns, which are known as ecological and medical textile materials, were investigated. The yarns were produced from SeaCell stapel fibres and then were woven into fabric. After dyeing, the fabrics flame retardants which has phosphorus-inorganic synergism and organophosphorus compounds (N-hydroxymethyl-3-dimethylphosphonopropionamide), were applied to the the SeaCellactive and SeaCellpure fabrics, and later the flame retardant properties were determined before and after washing processes. In addition to that, thermal properties of the fabrics and the effects of flame retardants were studied. The flammability of the flame retardant treated SeaCellactive and SeaCellpure were characterized by using limiting oxygen index (LOI). Structural changes of the treated SeaCellactive and SeaCellpure and the compounds were carried out by using thermal analysis methods of differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA). After flame retardant treatment on the 100% SeaCell fabrics, the LOI value of the sample with phosphorus-inorganic synergism reached to 31 % and after 15 successive washing the LOI value was 20%. On the other hand, while obtaining 28% LOI value with the application of the N-hydroxymethyl-3-dimethylphosphonopropionamide after 15 successive washing this was achieved only 26%. It was also observed that both DSC and TGA thermograms were verifies their results.
