Spinning Akund Fiber Into Yarn And Analysis Of Yarn Properties

Akund floss referring to yellowish,thin and hollow seed fiber that is not unknown,but not enough explored.The few published information about it indicate that it is very fine,hollow,yellowish fiber with smooth surface whose structure is similar to that of kapok,and its tensile strength comparable to that of cotton fiber.These characteristics make akund fiber an interesting target for research and increase the possibility for its application in textile purposes.This master thesis had the objective of converting akund fiber into ring spun yarn with favorable properties that will enable production of weaving and knitting fabrics.The properties,such as friction coefficient and strength of akund fiber previously treated with different chcemicals were tested.The results obtained were statistically analyzed in order to identitfying the most accurate chemical treatment for preparation of akund fiber for spinning.Blended akund cotton fiber mass was spun after identifying the most suitable parameters for carding,drawing,roving and spinning.The final product was akund/cotton blended yarn in ratio 67/33,in count 32Ne,with braking tenacity of 6,86 cN/tex;twist:726 tpm;3.34%elongation at break;Zweigle hairiness index of 3,87;and coefficient of variation by mass of 16,8%-properties that enable its application in textile purposes.
