How does chemistry affect the clothing that we wear?

Chemistry research is often full of surprises.  One such surprise came to Stephanie Kwolek of the DuPont chemical company.  She was working on a type of material known as polymers.  These chemicals had been around for a while and were being used for new types of textiles.  Kwolek was looking for a strong and rigid petroleum product.  She came up with a material that did not look like your average polymer.  But she played a hunch and had it made into threads.  This new material had stiffness about nine times that of any of the known polymers of the time.  Further research and development led to the production of Kevlar, a material now widely used in body armor (see figure above).  In addition, Kevlar has found wide application in racing sails, car tires, brakes, and fire-resistant clothing worn by firefighters.



Chemists are involved in the design and production of new materials.  Some of the materials that chemists have helped discover or develop in recent years include polymers, ceramics, adhesives, coatings, and liquid crystals.  Liquid crystals are used in electronic displays, as in watches and calculators.  The silicon-based computer chip has revolutionized modern society and chemists have played a key role in their design and continued improvement.  The calculator shown below uses both a liquid crystal display and chips inside the device.

Many chemists are currently working in the field of superconductivity.  Superconductors are materials that are able to conduct electricity with 100% efficiency, meaning that no energy is lost during the electrical transmission, as happens with conventional conducting materials like copper cable.  The challenge is to design materials that can act as superconductors at normal temperatures, as opposed to only being able to superconduct at very low temperatures.


The fibers that compose the materials for our clothes are either natural or human-made. Silk and cotton would be examples of natural fibers. Silk is produced by the silkworm and cotton is grown as a plant. Human-made fabrics include nylon, orlon, and a number of other polymers. These materials are made from hydrocarbons found in petroleum products. Synthetic polymers are also used in shoes, raingear, and camping items. The synthetic fabrics tend to be lighter than the natural ones and can be treated to make them more water-resistant and durable.

Materials originally developed as textiles are finding a wide variety of other uses.  Nylon is found in a number of plastic utensils.  Taking advantages of its strength and light weight, nylon is a component of ropes, fishing nets, tents, and parachutes.
