BISFA– the internationally recognised authority on technical standards and test methods in man-made fibres – has issued two new and updated standards on test methods for:
• Polyester staple fibres; and
• Textured filament yarns.
The new standards – replacing older ones first published 18 years ago – take account of changes in technology, markets and test methods.
They provide essential guidance to companies to help them produce fibres to high and consistent standards of quality, and to provide a neutral and objective basis on which to resolve any disputes about the technical properties of fibres supplied to customers.
The new standards cover criteria such as:
• Sampling
• Commercial mass
• Finish level
• Fibre length
• Linear density
• Tensile properties
• Twist
• Intermingling
• Spin finish
• Crimp contraction
• Hot air shrinkage
• Boiling water shrinkage
• Statistical process control parameters
• Terminology.
This international association of man-made fibre producers was founded in 1928 under the French name of Bureau International pour la Standardisation des Fibres Artificielles, hence the abbreviation BISFA. BISFA establishes terminology of man-made fibres for the continuous improvement of intercompany, customer and consumer communications.
