Objectives

The principal obstacles to getting appropriate polyester fibres quality have been:

• lack of clarity about and quantification of quality and
• problems of selecting appropriate means to control the process against the product objectives.

Very considerable and successful efforts have been made in recent years in all parts of the ICI Group to remove both obstacles. This paper is designed to summarize the results of the ICI Europa Systems Technology Group work in the last 3 years, it being understood that much of it has been done in close collaboration with factories in Europa territory, the UK and ICI Fibres RTD. For pressing commercial reasons results have been directed at improvements to the appearance of piece-dyed fabrics. However, the basic understanding developed has always been seen to have application to other polymer products, to the design of unit operations, and to the evaluation of technological strategy.
