Textiles — Determination of fineness of flax fibres — Permeametric methods

Fineness can be considered as a vital characteristic of flax. However, because their special structure, the measurements of the fineness of such fibres presents a difficult problem. Two permeametric methods for the determination of the fineness of flax fibres are specified (a reference method, with two compressions, using a test piece of parallel fibres and a simplified method, with one compression, using a test piece of fibres distributed at random). – Replaces the first edition (ISO 2370-1972).
