It is easy to make mixtures of the monomers or sets of monomers used to make nylons to obtain copolymers. On the other hand, nylon 6 is easy to dye, more readily fades; it has a higher impact resistance, a more rapid moisture absorption, greater elasticity and elastic recovery.
In springone of the Carothers team, Julian Hillaccidentally produced a strange gooey blob of material that he could draw out into long, thin fibers. Industrial synthesis is usually done by heating the acids, amines or lactams to remove water, but in the laboratory, diacid chlorides can be reacted with diamines.
The shorter skirts were accompanied by a demand for stockings that offered fuller coverage without the use of garters to hold them up. The most common variant is nylon 6,6, also called nylon 66, which refers to the fact that both the diamine and the diacid have 6 carbon backbones. This gives it almost the same carbon footprint as wool , but with greater durability and therefore a lower overall carbon footprint.
A polymer is a long molecule made up of monomers, which are identical smaller molecules that are bonded together in a chain. The solution found to problems with pure nylon fabric was to blend nylon with other existing fibers or polymers such as cotton , polyester , and spandex.
