Cotton/polyester Solo-Sirofil composite yarn

Cotton/polyester Solo-Sirofil composite yarn The effect of introducing a Solospun roller in the Sirofil spinning system in order to improve the properties of cotton/polyester composite yarns, especially the yarn hairiness was studied. For this purpose, as part of the experiment, 9 different cotton/polyester composite yarns, with yarn count (linear density) of 35 tex/75D, 39 tex/75D and 48 tex/75D, and twist factors of 390, 425, 460 were produced, by using the Sirofil spinning system, with and without a Solospun roller. Afterwards, the yarn physical properties including hairiness, breaking intensity, breaking elongation and irregularities were measured and compared. The results obtained indicate that the hairiness of Solo-Sirofil spun yarn was decreased by 90%, while yarn breaking elongation, breaking intensity and evenness were slightly deteriorated.
