The aromatic moiety itself does not participate in elimination reaction, but it does increase the rigidity and strength of the resulting material which leads to Kevlar's renowned strength. In the diagram below, an aramid is made from two different monomers which continuously alternate to form the polymer chain. Aramids are aromatic polyamides:
Microfiber fabrics are man-made and frequently used for athletic wear, such as cycling jerseys, because the microfiber material wicks moisture (perspiration) away from the body; subsequent evaporation cools the wearer. Microfiber can be used to make tough, very soft fabric for clothing, often used in skirts, jackets, bathrobes, and swimwear.
When dry, polyamide is a good electrical insulator. However, polyamide is hygroscopic. The absorption of water will change some of the material's properties such as its electrical resistance. Nylon is less absorbent than wool or cotton. The characteristic features of nylon 66 include: Pleats and creases can be heat-set at higher temperatures
Aramid fibers, short for aromatic polyamide, are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage , marine hull reinforcement, as an asbestos substitute, [ 1 ] and in various lightweight consumer items ...

The insulation qualities of clothing materials are determined by the amount of "dead air" they can hold. The air is held in the voids inside the material itself as well as in the gaps between the clothing layers. Of the natural clothing materials, fur and leather provide the best insulation.
Lint is the common name for visible accumulations of textile fibers, hair and other materials, usually found on and around clothing.Certain materials used in the manufacture of clothing, such as cotton, linen, and wool, contain numerous, very short fibers bundled together. [1]
