Transforming Competitive Swimming: The Science Behind Fastskins and Sharkskin Technology

Fastskins are advanced swimming suits made from synthetic fabrics derived from petrochemicals. These materials, which originate from the components of petroleum, undergo a process where liquid is spun and cooled to create solid threads that are woven into fabric. Inspired by sharkskin, Fastskins feature micro-structures that reduce water friction, enhancing a swimmer's performance. The design mimics shark denticles, promoting smoother movement through water and offering a gliding effect without adverse health impacts.

  1. FASTSKINS (SHARKSKINS) Cassidy Butler

  2. Composition • Fastskins are made from synthetic fabrics, which are made from petrochemicals • Petrochemicals are chemicals found in petroleum and natural gases • The components of petroleum (all basically composed of hydrocarbons)- • Gasoline • Dissolved natural gas • Benzene (picture) • Naphtha • Kerosene • Heating oils • Diesel fuel • Tars http://www.infoplease.com/ce6/sci/A0860338.html

  3. Production • Those components start out in liquid form and are put through fine holes in a spinneret. When they are out of the nozzle, they are cooled so they become solid and form threads, and are woven together to make a fabric. http://www.infoplease.com/dk/science/encyclopedia/synthetic-fabrics.html

  4. Operation • Fastskins improve competitive swimmer’s performances • Scientists got the idea of Fastskins from sharks. The denticles on a shark’s body make it so there is a low friction as it swims. These “denticles” were put on Fastskins to reduce the friction between the swimmer and the water, and also give a gliding sensation. • No health effects • http://www.ccmr.cornell.edu/education/ask/index.html?quid=1024
