| Abstract:
In this research core spun yarns were produced by three spinning systems namely ring, solo and siro spinning system under the same initial conditions such as filament pre-tension (100 gram) and twist per meter (T.P.M = 415), and then their physical and mechanical properties including strength, elongation percentage, abrasion resistance, CV% and hairiness were investigated. Moreover, the effect of feed position of core filament on physical and mechanical properties of siro core spun yarns studied and the best position was determined.
The results show that Solo core spun yarn has more strength than Ring and Siro core spun yarns; however, Siro core spun yarn shows better characteristics with respect to hairiness, abrasion resistance & CV percentage comparing to its Ring & Solo core spun yarns counterpart.
