Yarn hairiness controlled by modified yarn path in cotton ring spinning.

The influence of yarn path on spinning triangle and, in turn, on yarn hairiness has been studied. The yarns have been produced from cotton (40s Mali-juli and 60s MCU5) and 45s polyester/cotton (Recron/MCU5, 67:33) by varying the yarn path in right and left diagonals by spinning with adjacent spindles and then tested for hairiness, strength, unevenness and breakage. The test results have been compared with the respective conventional straight path yarns. It is observed that there is a 50% reduction in hairiness in the left diagonal path with slight increase in strength. Right diagonal path shows deterioration in spinning efficiency and no improvement in hairiness. [ABSTRACT FROM AUTHOR]
