In order to spin the aromatic nylon by the interfacial polycodensation, the experiments are carried out by the reaction between the hexamethylene diamine and isophthaloyl diacid chloride. The optimum spinning conditions for this case are as follows:
a) Molar ratio of the diamine to acid chloride=0.6
b) The interfacial area=48.7mm²
c) Temp. of reaction=55°C
d) The winding up speed=3.47m/min.
e) The concentration of NaOH=0.14mol/100 cc H₂O
f) The concentration of surfactunt (SLS)=1.17×10^-3mol/100 cc H₂O.
The Young's modulus of this fiber is five times greater than the 6.10 nylon after the drawing of five hundred percents.
