Dyeing of polyamide
WebDifferently, polyamide is a kind of man-made fiber with an almost hydrophobic surface, in which dyes are diffused into fibers based on the theory of free volume model (Cleve et al., 1997, Yan et al., 2024). Therefore, silk/polyamide fabrics with good color levelness are difficult to be dyed.
