Polyamide 6.6
General
It is the most produced fiber of polyamide fibers.
It is a thermoplastic polymer which is the crystal structure.
The adipic acid and hexamethylenediamine which are the starting materials of Polyamide 6.6, heated in ethyl acetate consist of Nylon 6.6 salt.
Solution of the salt in the water start to polymerization when holding under pressure and giving steam at 215-220º C.
When the desired degree of polymerization temperature, polymerization is terminated by adding acetic acid.
The polymer which is the milky white color and solid state is formed into filament by cutting in small pieces.
