The objective of this study was to determine the influence of cotton type in order to find out if it is possible to produce a carded compact yarn of comparable quality to the combed conventional yarn. Marzoli spinning frame was used to produce combed and carded cotton yarns with linear densities of 14.76 tex (40 Ne), 19.68 tex (30 Ne), and 29.53 tex (20 Ne), were manufactured from the same LS cotton (Giza 80 and Giza 90, as Egyptian cotton and MLS, Greece Upland cotton. Combing was carried out 18% noils during the combing process. Within the tests carried out, the followingquality parameters were analyzed of fiber and yarn quality properties such as single yarn strength, elongation, mass irregularity, yarn faults, and hairiness. Yarns spun on the Olfil carded compact spinning frame were found to have the following advantages when compared to those spun on the combed ring spinning frame: higher strength and elongation at break, somewhat equivalent or higher yarn unevenness, and a significantly lower number of yarn faults such as thin, thick places and neps, as well as a lower hairiness. This study also revealed that compact spinning could be used for producing coarse and medium yarn counts from 20s to 40s, from Long staple Egyptian cotton with comparable quality to the combed conventional ring spun yarns
