How is nylon made step by step?

Answer 1

Nylon is made through a process called polycondensation, primarily involving the reaction of diamines with dicarboxylic acids or their derivatives. The steps typically include: 1) reacting hexamethylenediamine with adipic acid to form a salt; 2) heating this salt to initiate polymerization, which produces the nylon polymer; 3) extruding the polymer into fibers; and 4) cooling and stretching the fibers to enhance their strength and elasticity. The resulting nylon can then be spun into textiles or used in various applications.
