摘要：

Cotton and wool fabrics were dyed with the natural dyes chlorophyll and carmine after treatment with the enzymes cellulase, alpha-amylase and trypsin. Wash and light fastnesses of the dyed samples were studied. Enzymatic pretreatment resulted in an increase in pigment uptake in all cases compared with the corresponding untreated samples, and did not affect fastness properties. Pretreatment with metallic salts and dyeing of pretreated samples was also carried out and the fastness properties of the dyed materials were studied. The effect of conventional mordanting with metallic salts was compared with that of enzymatic treatment on the dyeing properties of the dyes used.
