SIFAN (Single Fibre Analyser) produces a three dimensional model of the fibre by measuring the diameter at predefined number of angles.A length of fibre usually has a cross section that varies along its length. A fact which has a major influence on the fibre strength and breaking point. SIFAN is a compact test machine that was developed to meet the demand for fibre research with a new level of detail.

SIFAN measures the diameter along a single fibre from several directions at a number of pre-programmed tensions to produce 3 dimensional Models of fibres at increasing strain.

SIFAN also measures the force breaking curve after the diameter measurement and hence strength and fibre elongation, which determines the tenacity of a fibre. It works according to the principle of the constant deformation rate, i.e. the clamps with the clamped fibre depart from each other with constant speed. Strong yarn can not be made from weak fibres, therefore it is so important for the spinning mill and fibre research to measure both the fibre strength and fibre elongation with consideration to the fibre fineness along the fibre.
