This review concerns the application of vat dyes, sulphur dyes, azoic colorants, direct dyes and reactive dyes to both natural and man-made cellulosic fibres from aqueous dyebaths using exhaust dyeing processes and the role of added inorganic electrolyte in such dyeing processes. In this part of the paper, the various theories/hypotheses/concepts which have been proposed to account for the promotional effect exerted by added inorganic electrolyte on dye uptake are reviewed and scrutinised, from the viewpoints of the essential physico-chemical properties of the five classes of dye used and the fundamental aspects of their application.

无机电解质（盐）在纤维素纤维染色中的作用：第 2 部分关于无机电解质如何促进染料吸收的理论

本综述涉及还原染料、硫化染料、偶氮染料、直接染料和活性染料在使用浸染工艺的水性染浴中对天然和人造纤维素纤维的应用以及添加无机电解质在此类染色工艺中的作用。在本文的这一部分中，从五种基本物理化学性质的角度，回顾和审查了各种理论/假设/概念，这些理论/假设/概念已被提出来解释添加无机电解质对染料吸收的促进作用。使用的染料类别及其应用的基本方面。
