“…Although few reports available on PVAc/MF blend, there is a scarcity in the literature on the studies of MF incorporated PVAc‐polyester nonwoven fabric composites. In the previous communications, the authors have studied the effect of MF on the physicomechanical and water sorption behavior of the composites 18, 19. In the present research article, authors have reported the effect of MF contents on the thermal stability of PVAc‐polyester nonwoven fabric composites using TGA and on the material morphology using scanning electron microscope (SEM).…”

The objective of the present research work is to study the effect of different amounts of melamineformaldehyde (MF) viz., 0-20 parts by dry weight on the thermal stability of polyvinyl acetate (PVAc) latex impregnated polyester nonwoven fabric composites. From the thermogravimetric analysis, the improvement in thermal stability of the composites was noticed with increase in the MF content. Composites fabricated with five parts MFincorporated PVAc showed a drastic increase in the onset degradation temperature when compared with unfilled composites. It was found that the degradation of MFloaded PVAc-polyester nonwoven fabric composites takes place in two steps. Degradation kinetic parameters were calculated for the composites using Broido and HorowitzMetzger methods. The tensile fractured composite specimens were analyzed using scanning electron microscope to know the morphological behavior. The increased percentage ash content also supports for the increased thermal stability of the composites with increasing the MF content in the system. The adhesion between the fiber and matrix can be seen from scanning electron microphotographs.

Phosphorus-containing poly(ethylene terephthalate-co-diethylene terephthalate) (PEDT) with a low melting temperature was synthesized through esterification and copolycondensation of terephthalic acid, ethylene glycol, diethylene glycol (DEG), and 3-(hydroxyphenylphosphinyl)propionic acid (HPPPA). DSC results showed that PEDTs still were crystallizable and that the lowest melting temperature of the PEDTs was reduced to 118.0 °C although the chain regularity was destroyed by the incorporation of comonomers. It was found that the addition of HPPPA can improve the thermal oxidative stability of copolyesters. The results of the limiting oxygen index (LOI) test, the UL-94 vertical test, and the cone calorimeter test indicated that HPPPA endowed PEDT with good flame-retardant properties. The LOI values of the PEDTs were increased to 30.5−34.8, the UL-94 ratings of vertical burning were improved to V-0, and both the peak heat release rate (pHRR) and the total heat release (THR) obviously decreased.

Composites were fabricated by impregnating needle punched polyester nonwoven fabric in the latex composition containing PVAc/MF (90/10) blend. Different amounts of flame retarardant (FR) were incorporated into PVAc latex blend viz., 100/0, 90/10, 80/20, 70/30, and 60/40 dry, weight-by-weight. The selected FR was a synergistic FR system containing antimony trioxide and brominated organic additive. The effects of different amounts of FR in PVAc/MF latex blend on physico-mechanical properties like tensile strength, percentage elongation, specific tensile strength, and reinforcement factor of the composites have been studied. The combustion behavior of the composites has been studied using the cone calorimeter. The combustion studies revealed that the incorporation of FR significantly lowered the percentage mass loss and heat release rate of the composites. A linear relationship was found between the total oxygen consumed and peak heat release rate. From the results, it can be observed that the rate of heat release, peak heat release rate, and the total oxygen consumed by the composites have been significantly reduced with increase in the FR. The total smoke production and smoke release rate of the composites have been increased with increase in the FR. The arbitrary scale developed by Petrella was discussed to assess the hazard of composites.
