The Birth of Nylon: A Milestone Breakthrough in Polymer Science In 1935, American scientist Wallace Carothers (1896–1937) went through a long and arduous research process and proposed the epoch-making **condensation polymerization theory**. This theory, like a "golden key" opening the door to the mysterious palace of polymer science, laid the core foundation for synthetic polymer materials.
After hundreds of failed experiments, Carothers finally succeeded in developing polyamide material (i.e., nylon 66). This achievement broke humanity’s 5,000-year dependence on natural fibers and was praised by the industry as "claiming the pearl on the crown of fibers," completely ushering in a new era for the synthetic fiber industry.
The synthesis of nylon not only laid the foundation for the synthetic fiber industry but also took the lead in bringing disruptive changes to the textile sector. Stockings woven from nylon fiber combined transparent texture with ultra-high wear resistance, outperforming traditional silk stockings by a wide margin.
On October 24, 1939 (the original text mistakenly wrote "10 目" [10th mesh] which should be "10 月" [October]), DuPont publicly sold nylon stockings at its headquarters location, instantly causing a market sensation. At that time, nylon stockings were regarded as rare treasures, and people scrambled to buy them. People even used the praise "as slender as spider silk, as tough as steel wire, and as soft as silk" to describe this epoch-making fiber material.
With the outbreak of World War II and until the end of the war in 1945, the production direction of the nylon industry was urgently adjusted to focus on the military sector. Leveraging nylon’s properties of high strength and light weight, it was used to mass-produce key military supplies such as parachutes, aircraft tire cords, and military uniforms. This not only provided important support for wartime material security but also further verified the multi-functional application potential of nylon materials.
