Hilaire de Chardonnet

Hilaire de Chardonnet (* 1. May 1839 in Besançon; † 12. March 1924 in Paris) was a French chemist and Industrieller and became famous by the invention of artificial silk.

Chardonnet was actually a civil engineer, worked however for Louis Pasteur. Chardonnet became attentive on studies of Pasteur, which concerned themselves with diseases of the silk crawler-type vehicle. Thereupon it looked for an artificial replacement for silk. Its point of origin were Maulbeerblätter, the food of the silk worms. It transformed these into a cellular fibrous material with nitrogen and sulfuric acid and stretched it to fibers. The original fibers were extremely inflammable, but in the year 1889 this problem was solved and it developed the celanese.

In the year 1891 artificial silk was shown for the first time on that Paris exhibition and was at that time a sensation. It was called at this time “Chardonnet silk”. It created this, by it Nitrozelloluse to Chardonnet silk strut, first industrially produced synthetic fiber and a forerunner of celanese, nylon, and Dacron.

Chardonnet opened factories for the production of celanese.
