Nylon is a polymer which contains an amide group regularly interspersed along the repeat units of the polymer chain. Nylon 6/6 is the most common type of Nylon, it contains an amide group after every 6 carbon atom. Due to the presence of the amide group the Nylon polymer is highly polar in nature, and due to its high polarity Nylon acquires a crystalline structure. The sequence of atoms as shown in the diagram repeats over and over hundreds of times resulting in a very large molecule.
A molecule of nylon has a structure similar to that of a protein molecule. (The Science of Nylon) Mechanism of synthesis of Protein Nylon 6/6 is made from monomers adipic acide and hexamethylene diamine. In the process of manufacturing Nylon 6/6 the monomers adipic acid and hexamethylene diamine are made to react in methanol. This process leaves behind a precipitate of nylon salts. The Nylon Salts are then washed in water and then acidified in order to cause polymerization.
The polymers are then washed and dried in preparation for the spinning process which converts the dried pieces of Nylon polymers into fibers..
Nylon possess following properties which make it an excellent materil;
Nylon has many applications it is used widely for making clothes and tooth brush bristles, it is also used for making medical sutures. Due to its high strength it is used for manufacturing engineering equipments.
