Aramid are manmade organic fibers produced from aromatic polyamides. Polymerization of monomers TDC, PPD along with NMP, CaCl2 solvents results in PPTA.AT this stage chemical and heat resistance properties are obtained but is in powder form. During coagulation extraction with H20 solvent is recovered .Next stage involves dissolving polymer in sulphuric acid at low temp.-10oC.Self oriented liquid crystal molecules are obtained by extrusion which imparts good mechanical properties. Aramid fiber variants are standard modulus, high modulus and high tenacity fibers. Modulus can be increased during heat treatment under tension at 4500C.
