Natural bamboo fibers were alkalized by caustic soda in slack state, and then subjected to direct dyeing. The influences of caustic treatment on the dyeing behaviours of bamboo fibers were investigated and the reasons for the change in their dyeability were discussed. The maximum increase in the uptake of direct dyes occurs for the bamboo fibers alkalized with the caustic soda solutions of the concentrations ranging between 115 g/L and 130 g/L, while the uptake almost keeps constant after the concentration of caustic soda solution is above 160g/L. The equilibrium exhaustion, substantivity, dyeability and building up properties of bamboo fibers are poorer than those of cotton fibers. These dyeing behaviours of bamboo fibers can be greatly increased to the comparable extents with those of cotton fibers if they are alkalized with the caustic soda solution of the concentration exceeding 190 g/L.
