![]() ![]() Nylon 66 lends itself well to make 3D structural objects, mostly by injection molding. For textiles, fibers are sold under various brands, for example Nilit brands or the Cordura brand for luggage, but it is also used in airbags, apparel, and for carpet fibres under the Ultron brand. It is used in fibers for textiles and carpets and molded parts. Nylon 66 is frequently used when high mechanical strength, rigidity, good stability under heat and/or chemical resistance are required. Fiber markets represented 55% of the 2010 demand with engineering thermoplastics being the remainder. ![]() It is not used in films due to its inability to be oriented. At that time, fibers consumed just over half of production and engineering resins the rest. In 2011 worldwide production was two million tons. It can either be extruded and granulated at this point or directly spun into fibers by extrusion through a spinneret (a small metal plate with fine holes) and cooling to form filaments. N ( HOOC − ( CH 2 ) 4 − COOH ) + n ( H 2 N − ( CH 2 ) 6 − NH 2 ) ⟶ n + ( 2 n − 1 ) H 2 O Removing water drives the reaction toward polymerization through the formation of amide bonds from the acid and amine functions. ![]()
