How Is Nylon Made In Factories?

How Is Nylon Made In Factories? -- Nylon production in factories begins with a chemical process called condensation polymerization. The most common type, Nylon 6,6, is made by reacting two monomers derived from crude oil: hexamethylenediamine and adipic acid. These chemicals are heated together in a pressurized reactor, causing them to link into long, repeating polymer chains and form a molten substance known as nylon salt, releasing water as a byproduct. This molten polymer is then extruded through a spinneret, a device resembling a showerhead with thousands of tiny holes, to create continuous filaments. As these filaments emerge, they are cooled by a blast of air, which causes them to solidify. The crucial final step is "drawing," where these solid fibers are mechanically stretched to several times their original length. This process aligns the polymer molecules, imparting nylon's signature strength, elasticity, and durability before the fibers are wound onto bobbins for use in textiles and other products. ⚠️ Disclaimer: Videos are created for educational purposes only and do not constitute professional, medical, financial, or legal advice.
