To reveal the effect of acid dyes on the melt processing of recycled nylon 66, 17 acid dyes with different chemical structures were used to dye a nylon 66 yarn. The thermal stability of dyestuffs, the thermal degradation of the dyed nylon 66 during compression molding, and the melting and crystalliz

The sorption behavior of acid dyes by a nylon 6 film was investigated in the presence and absence of a bolaform electrolyte. The time dependence of the sorption changed with the pH values of the dye bath. At pH 3, equilibrium sorption was not established even after the immersion of the film in the a
The yield stress of nylon filament dyed with several acid dyes has been determined as a function of dye content and the molecular weight of acid dyes. The nylon filament dyed with acid dye has greater yield stress than undyed one. The relation between the increment of the yield stress ( f ) due to t
