Summary

In this study, flame retardant modification of partially oriented (POY, partially oriented yarn) poly(ethylene terephthalate) (PETPOY) fibers were applied using a high temperature bath method similar to dyeing fibers with disperse dyes. The flame retardant modifier used in this work – water-glass (WG) – was commercially available technical product. The flammability of fibers was evaluated by limiting oxygen index (LOI) method. Samples of the modified fibers were examined by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Effect of the flame retardant on change in the supermolecular structure of PETPOY fibers was evaluated using wide- and small-angle X-ray diffraction (WAXS and SAXS). As a result of the applied modification, PETPOY fibers were provided with effective and durable flame retardant properties. Also noteworthy is the relatively low cost and simplicity of applying the proposed technology.
