Zusammenfassung: | A composite material is dyed with a dyestuff which is a reactive dyestuff or a combination of a reactive dyestuff and a dyestuff selected from an acidic metal containing dyestuff and dispersing dyestuff wherein all dyestuffs are solved in one bath. The reactive dyestuff is selected according to a classification based upon the ratio of tone of the dyed article of the synthesized polyamide fibre with respect to a cellulose fibre and a compensated color difference, the synthesized polyamide fibre and the cellulose fibre being dyed in a same bath. The composite material contains a single element selected from polyamide fibre and cellulose fibre, or an element selected from fibre and an element selected from cellulose, polyarylic and polyester fibre. |
