________________________
The production of aramid fibers known under their trademark names Kevlar® and Nomex.® have unique and beneficial properties. These two aramids are similar in basic structure and are sometimes produced in the same production plants. The difference is in their structure, Kevlar® is a para-aramid while Nomex® is a meta-aramid. An aramid is a polyamide where at least 85% of the amide bonds are attached to aromatic rings. The first aramid produced was called Nomex® introduced by Du Pont in 1961. For this report we will dissect each fiber separately.

Aramid is a synthetic fibre that is produced by spinning a solid fibre from solution. ... This is necessary to keep the highly insoluble polymer in solution form during synthesis and spinning. The manufacturing process of Kevlar is expensive and dangerous partly because it is dissolved in concentrated sulfuric acid.
