'Back 2 Basics' Learning from experienced observation

摘要

This paper is designed (hopefully) to be informative and instructional rather than promotional. It does not seek to recommend one system of reactive dyes at the expense of another. Neither does it propose to recommend one modus operandi against another. Rather, it sets out to discuss the critical success factors of a reactive dyeing operation, how they relate to the requirements of a particular form of application to the cellulosic substrate, and how they can be optimised by an audit of "the basics" . The reactive dye system which might be considered optimum for pad-batch, for example, might not necessarily be the preferred choice for exhaust dyeing ( and vice versa). And, almost certainly, the preferred choice for continuous dyeing would not always be entirely suitable for exhaust dyeing. Since the most commonly used form of application of reactive dyes to cotton is currently that of exhaust dyeing, then this paper will concentrate on that application sector.
