Abstract
Quality of end product in spinning can improve significantly by combing and removing of short fibers. Combing process removes short staple fibers and eliminates the impurities which are present in carded sliver or in drawn sliver. In comber sliver, the fiber strands are straighter, parallel and align while the end yarn produced has smoothness, clear appearance, and more strength.
If we check all the processes in yarn manufacturing in spinning process, the combing processes is the one which has a significant effect on improving yarn quality. The short fibers removed in the combing process are called Noil. The noil extraction in the combing process has a direct effect on yarn quality but it has a limitation as well because increasing the noil extraction also increases the cost of yarn. Trails have been carried out on carded yarn, along with 12%, 16% and 20% Comber Noil on 54/s yarn respectively while keeping the other parameters constant from blow room to winding and conditioning in spinning yarn manufacturing. Then the results for mechanical properties of yarn were compared for these noil percentages. We find as expected that the increasing noil extraction improves yarn quality but these improvement in results are getting less distinguishable as we go up extracting more noil. In our results, we find, there is less difference in the properties of yarn having Noil extraction between 16% and 20% respectively.
