摘要

The dyeability of chemical pulp and chemithermomechanical pulp (CTMP) and their mixtures with direct dyes were investigated. It was found that direct dyes were useful mainly for dyeing paper containing chemical pulps, but they can also be used for high-yield pulps (with high lignin content -for example BCTMP), reducing costs as a result of using cheaper fibrous semi-products. When increasing the amount of high-yield pulp in the paper product, we have to take into account that after dyeing the colour may change markedly in comparison to dyed chemical pulps.
