A well-known type of aramid fiber (a Para -aramid Nylon ) is commonly known by its DuPont trade name, Kevlar , or Teijin trade name Twaron. It was developed by Stephanie Kwolek . An especially Fire proof Meta variant is Nomex . ARAMID FIBER CHARACTERISTICS
MAJOR INDUSTRIAL USES
PRODUCTION The Federal Trade Commission definition for Aramid fiber is "A manufactured fiber in which the fiber-forming substance is a long-chain synthetic polyamide in which at least 85% of the Amide Linkages are attached directly to two aromatic rings." Aramid fiber is produced by Spinning a Solid fiber from a Liquid chemical blend. This relies on a co-solvent with an Ionic component ( Calcium Chloride ) to occupy the Hydrogen Bond s of the ''amide'' groups, and an organic solvent ( N-methyl Pyrrolinidone ) to dissolve the Aromatic Polymer ; prior to DuPont's (Kwolek's) invention of this process, no practical means of dissolving the polymer was known. First U.S. Commercial Aramid Fiber Production: 1961, DuPont Company. Current U.S. Aramid Fiber Producers: INVISTA SEE ALSO |
