Abstract: The spinning system employed for the spinning of coir yarn from coir fibers follows the principle of open end spinning. Coir yarn produced by manual or mechanical means is of two ply structure. The single yarn produced by the mechanized process is a an open end type of yarn where two single yarn from the adjacent spinning heads are converged together and then twisted together before winding it on a bobbin. The single yarn produced is of core yarn type and the core component is generally a mono filament polyester fiber, with coir fibers wrapped over the filament to form a sheath. Fiber length distribution, packing fraction and breaking strength of both single and two ply coir yarn were tested and analyzed.
Keywords: Coir Fiber, Core Spun Yarn, Fiber Length Distribution, Packing Fraction, Sheath Fibers, Wrapper.
