Individual amide molecules forming the aramid chain polymerise in the direction of the fiber axis, lending greater structural integrity to the resulting fiber. This is due to the higher proportion of chemical bonds which contribute to the physical strength and thermal resistance (melting point >) versus other synthetic fibres, such as nylon.
