1. Abstract
Polyester Microfibres offer higher levels of value addition in the Textile Supply Chain. However, the large internal surface area, much larger than with conventional polyester fibres, poses particular problems to the processor. This applies especially to the chemical preparation and dyeing stages.
The dyeing of microfibres is an extensive subject. There is insufficient space in this column to cover the question fully. It is hoped that the basic principles are outlined here, sufficiently to tempt interested readers to further their research by reference to the book about to be published entitled Polyester World.

Synthetic Microfibres should certainly be regarded as a higher value added sector driven by Niche Performance.

2.3. Definition of a Microfibre
Decitex - the weight in grammes of 10,000 metres of yarn
Denier - the weight in grammes of 9,000 metres of yarn
Hence, a 176 decitex yarn can also be described as a 150 denier yarn
