As explained earlier, Kevlar is a polymer. A polymer is comprised of monomers, or simply individual molecules. The monomers are attached in a series of chains that creates the polymer. A polymer is synthetic or man-made, which means it is prepared in a lab.

Kevlar is also a carbon-based aramid. The name aramid is an abbreviation for aromatic polyamide.

Kevlar does not start out as a polymer. Like all other synthetic substances, it has to undergo a fabrication process. A condensation reaction with a diamine, a terephthalic acid and sulphuric acid create the substance that will become the final product. A diamine is any organic compound containing two amino groups (NH2) while a terephthalic is a carboxylic acid that consists of a benzene ring in its molecule.

The substance that the condensation reaction has created is called the intermediate. In order to make the Kevlar, it must be drawn. Drawing is essentially stretching the product at a set temperature to strengthen the product. Once the intermediate has been drawn, poly-para-phenylene terephthalamide is created, or simply, Kevlar 29. In order to become a stronger product, Kevlar 29 must be hot-drawn at 400ºC. Hot drawing allows higher degrees of strength and crystallinity and this creates Kevlar 49, the strongest type of Kevlar.

Once the Kevlar has been drawn it must be spun to produce the filaments. In order to do so, it is extruded though a spinneret. After this, it is washed and neutralized and then taken to be dried. The final step of the manufacturing process is winding the Kevlar into spools. This creates a more flexible approach for the buyers so that they can use the threads for their needs instead of buying the Kevlar in sheets.
