Abstract
Compact spinning is the modification of existing ring spinning technology. The structure and quality of yarn are improved by using this spinning technique. This experimental work explores the effect of air suction pressure on the quality of compact yarn. Due to this reason, five samples of 52 Ne yarn were produced using different negative suction pressures such as 17 mbar, 19 mbar, 21 mbar, 23 mbar and 25 mbar (1 mbar = 100 Pa) in Suessen Elite@ system by changing the frequency of inverter. Samples were collected and then results were carried out. After that, the quality parameters of the produced yarn such as Mass variation (CVm%), Imperfection index, Hairiness and Count Strength Product (CSP) were analyzed along with calculating the power consumption against different suction pressures using the inverter frequency. Finally, the test results showed that yarn obtained from 23 mbar negative suction pressure was optimum considering the yarn quality and power consumption compared to others. This experimental work will provide an idea for spinners’ to choose optimum suction pressure for producing minimum imperfection and hairiness of compact yarn.
