There are certain abbreviations that you will find often. So, to make things easier for you, we have added a list below:

BISFA – Bureau International pour la Standardisation des Fibres Artificielles, or The International Bureau for Standardisation of Man Made Fibers.

CIRFS – Comité international de la Rayonne et des Fibres Synthétiques or the European Man Made Fibers Association
