Testing Methods

1. Mechanical tests

1.1 On fibres: fineness, staple length, tensile strength and crimp.

1.2 On yarns: count, twist, regularity, cleanliness, faults, tensile strength, crimp, crimp rigidity, abrasion and shrinkage.

1.3 On fabrics: fabric mass, fabric sett, fabric density, thickness, tensile strength, slip resistance, seam strength, tearing strength, bursting strength, abrasion resistance, crease recovery, air permeability, water resistance, shrinkage, elasticity, flexural fatigue, moisture and water (sorption and desorption) and pilling resistance.

2. Physical tests

Heat resistance, melting point, flammability, electrostatic behaviour, heat conduction, optical properties, lustre and physiological properties.

3. Chemical tests

Analysis of fibres and finishes, degree of whiteness, colour, dye affinity and colour fastness.
