Yam hairiness is reflected the amount of free fibers protruding from the spun yam body towards the outer yam surface. From a spinning point of view, studying this phenomenon is considered essential step because it influences the post spinning operation and the characteristics of the end textile structure. Many spinning factors are affecting the yam hairiness. The main objective of this search is to examine the effect of yam count and twist multiplier on yam hairiness under six different spinning systems. Accordingly, three yam counts (40's, 50's and 60's Ne) and three twist multipliers (4, 4.4 and 4.8) were applied. The used spun systems were carded, combed, carded compact, combed compact, jetring carded and jetring combed systems. Three-dimensional response surface graphs were used to easy and faster understand the results. Results indicated that the lowest hairy yam was spun by jetring combed spinning system with significant differences compared to the other spinning systems. Jetring carded and combed compact ring spinning systems occupied the second order regarding the production of the least hairy yams with significant differences than the others. Overall the used spun systems, it is indicated that the hairy yams may be dramatically decreased with increasing yam count to a certain extent and then slightly decreased while the hairiness was gradually decreased with increasing twist multiplier. However, the percentage of decrease % of hairy yam with increasing yarn count was greater than that observed by increasing twist multiplier under all spun systems. Multiple regression analysis exhibited that yam count and twist multiplier explained the most variation of hairiness expressed as high values of coefficient of determination (R2 %). Also, it is presented that the relative importance % of yarn count toward yam hairiness was greater than that observed by twist multiplier overall applied spun systems. |
