Nylon Patent
A filament of nylon may have a million or more molecules, each taking some of the strain when the filament is stretched. It was exactly what Du Pont had hoped for, and nylon was patented in 1935.

Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melt-processed into fibers, films or shapes. Nylon was the first commercially successful synthetic thermoplastic polymer. DuPont began its research project in 1930. The first example of nylon was produced using diamines on February 28, 1935, by Wallace Hume Carothers at DuPont’s research facility at the DuPont Experimental Station.
