Compact cotton yarn

This article presents an analysis and comparison of the parameters of cotton yarn spun on the Fiomax EliTe compact spinning frame from Suessen, and on the PJ 34 conventional ring spinning frame. Combed and carded cotton yarns with linear densities of 15 tex, 18 tex, and 20 tex were manufactured from the same middle staple cotton on both spinning frames, by eliminating 24% of the noils during the combing process. Within the tests carried out, we analysed the following quality parameters of slivers and rovings: the linear density, the mass irregularity, and the tensile strength of the fibre stream (the cohesion strength). We have also assessed and analysed the quality parameters of yarns, such as tenacity, elasticity, mass irregularity, yarn faults, and hairiness. Yarns spun on the EliTe compact spinning frame have the following advantages when compared to those spun on the PJ spinning frame: higher tenacity and elongation at break lower mass irregularity measured on short segments, and a significantly smaller number of faults such as thin & thick places and neps, as well as a higher degree of elasticity, and a considerably lower hairiness.
