Natural protein animals fibres are essential source in textile materials make use of wide range production yarns, warp and woven fabric. In this study single fibres and yarns were taken from 3 grade of animals: alpaca, merino and goat. All of this samples were tested destructively in axial direction using a uniaxial material testing machine. The mechanical properties between different animals fibres and yarns were determined by the force-displacement and stress-strain curves. The results of the experimental tests define strength, stiffness and high quality of textiles.
