   PROPERTIES AND USES OF NYLON 66                        

 Nylon comes from a family of synthetic polymers known as polyamide . It was first introduced by Wallace Carothers on 28th February 1935.Nylon 6,6 is a polyamide made by polycondensation of adipic acid  methylenediamine , and contains  a total of 12 carbon atoms in each repeating unit . The properties which make Polyamides suitable for plastic applications are resistance to toughness , thermal stability , good appearance , resistance to chemicals etc .The advantages of Nylon 66 are-                                                                                                                                                                                                                                               1.Nylon 6,6 persues excellent abrasion resistance and a high melting point .

2.Nylon 6,6 has  high tensile strength and exhibits only half of shrinkage in steam .

 3. It also provides a very good resistance to photo degradation .

 4.Nylon 6,6 also has good advantage over industrial products because it reduces moisture sensitivity in raw products and has a high dimensional stability and melting point .

The fact that makes Nylon 6,6 resistant towards heat and fraction and enables it to withstand  the heat for retention is that it has a melting point of 268 degree C for a high synthetic fibre . The physical properties of nylon 6,6 is that :

1. Nylon 6,6 has a repeat unit with molecular weight of  is 226.32 g/mol and crystalline density of 1.24 g/(cm)^3 .

2.Nylon 6,6 has long molecular chains resulting in more  hydrogen bonds , creating chemical springs and making it very resilient .

3. Nylon 6,6 is an amorphous solid so it has a large elastic property and is slightly soluble in boiling water .

4.Nylon 6,6 is very stable in nature.

5. Nylon 6,6 is very difficult to dye but once it is dyed it has a high colorfastness and is less susceptible to fading .

6. Its chemical properties does not allow it to be affected by solvents such as water , alcohol etc .

The applications of Nylon 6,6 is :  >  Because Nylon is a light material , it is used in parachutes .

 > Nylon 6,6 is waterproof in nature so it is also used to make swimwear.

 > Nylon 6,6 having a high melting point make it more resistant to heat and friction so it is suitable to be used in  in airports , offices and other places which are more liable to wear and tear .                                                     > Nylon 6,6 being waterproof in nature is used to make machine parts. It is also used in the following like airbags , carpets , ropes . hoses etc . Hence Nylon 66 is a very useful creation by mankind .
