A novel idea to prepare anti-dripping polyethylene terephthalate (PET) fibers is presented. The novel process incorporates benzoguanamine (BG) into PET resins with a melt spinning extrusion method, and then forming complex fibers through reactions between the BC and formaldehyde. The reactions to form the fibers and their thermal degradation behavior were investigated by Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA). In combination with the elemental contents on the surface of the complex fibers (found by Energy Dispersive X-ray spectrometry (EDS)), we find that the anti-dripping property depends on the formation of a three-dimensional crosslinked polymer. When the content of BC in the sample is 10%, the UL-94 rating is V-0 and no dripping phenomenon is found while performing the UL-94 measurement.
