This document defines the principal terms used to describe the various forms into which textile fibres can be assembled, up to and including cabled yarns.

It contains only terms of general application. Terms and definitions which are specific to particular fibres (such as hemp, silk, textile glass fibre, metal fibre, carbon fibre, etc.) are excluded.

A morphological scheme as shown in Annex A is included which illustrates the relationship among various terms from a production point of view.

This document does not include terms which describe the manufacturing or processing methods, or terms used to quantify fibre and yarn properties.
