Abstract | ||
Angora Rabbit hair has received special attention in recent years in Iran. Some of its specifications such as fineness, uniform diameter, snowy-white colour, softness and bulkiness have made it a precoius raw material in texile industries. For the first time, Jahad imported 206 rabbits from New Zealand in 1988 in order to grow the hair for it's textile application as raw material for yarn and fabric manufacturing. This study aims at assessing some important physical and mechanical specifications of Angora Rabbit fibres such as staple length, fineness, crimp, grease, breaking strength and breaking elongation to point out and justify the effect of the new environment and nutrition on fibre properties. The general stress-strain behavior of fibres is studied as well. The results show that the fibres continue to keep their desirable properties such as fineness and uniform diameter, characteristics arrtibuted to the controlled nutrition of Angora Rabbits. The multi-serial moduli a structure, surface morphology and scale density have been studied by Scanning Electron Microscopy (SEM). The interaction between the fibre properties and its spinning behavior is studied to evaluate the controlling effect of physical, mechanical and structural specifications of Angora Rabbit fibres. It was found that the main barrier in spinning of Angora Rabbit fibres is the slippage of fibres and their poor cohesion which leads to hair dropping through various stages of spinning procedure. | ||
