ABSTRACT

Ultramicrofiber(UMF) PET knitted fabric and regular PET plain woven fabric as reference sample were impregnated with waterborne polyurethane(PU) in a two-step process with dyeing/PU treatment and PU treatment/dyeing to investigate the effect of the treatment sequence. The waterborne PU impregnated fabrics were dyed with two kinds of vat and disperse dyes to investigate the dyeing properties and the dyeing fastnesses. In vat dyeing the rank of color strength(K/S) was in order of dyeing/PU impregnation>dyeing only>PU impregnation/dyeing, whereas in case of disperse dyeing, the order was dyeing/PU impregnation>PU impregnation/dyeing>dyeing only. Wash fastness of vat dyeing showed a higher 2-3 grade than disperse dyeing, while rubbing and light fastnesses were not good for disperse dyes.
