Poly(thioether ketones) are, in a sense, derived from polythioethers through the appropriate choice of monomers. Poly(phenylene sulfide) (PPS), which is the polythioether that has been investigated most, is an excellent engineering plastic with outstanding thermal, mechanical, and chemical stabilities; in certain areas of application, it has inherent advantages over even the polytetrafluoroethylene polymers.1–4 The thermal stability of the poly(thioether)s is probably because their structure involves C–C, C–H and C–S bonds, all of which are thermodynamically stable. PPS retains about 40% of its original weight at 1000 °C under nitrogen.

Polyphenylene sulfide (PPS) is a semi-crystalline thermoplastic with an excellent chemical resistance. Polysulfone (PSUL) is an amorphous thermoplastic with very high elongation to failure and excellent stability under hot and wet conditions.

The effect of 3DOW fabric engineering in electromagnetic shielding is estimated in this paper. The present work is designed according to response surface methodology (RMS), Box and Behnken’s experiment design. Polyphenylenesulfide (PPS), a semi-crystalline thermoplastic material, has found versatile applications due to its outstanding electrical properties, mechanical strength, thermal stability, and inherent flame-retardant potential (Minisik et al., 2020; Rabate et al., 2013). The copper filament diameter was selected in the range of 0.10 to 0.12 mm to manufacture 2D knitted fabric for EMS purposes (Perumalraj & Dasaradan, 2009). The copper filament diameter, the linear density of PPS fiber, and the hybrid yarn are altered to create different 3D orthogonal fabric samples.
