摘要

The current reactive dyeing process for cotton involves alkali addition as a separate step in the dyeing process. The fundamentals of cellulose hydroxyl dissociation were studied according to temperature and buffer system. Those reactive dyes tested could be fixed on cotton under neutral conditions in the presence of a buffer. Advantages of the new system are simplicity of operation, since the bath is set at pH 7-7.5 with a buffer, raised to the predetermined temperature, and held at this temperature for one hour; better dye levelness; comparable or even better fixation values than with the current alkali-based fixation process; and a system that offers the ability to dye cotton/wool blends.
