The aim of this work is to establish spinning equipment and conduct a metrological comparative analysis with traditional spindle methods and openend industrial spinning. To achieve this, five selected artisans were tasked with producing yarn using both sets of equipment, using conventional cotton fibers in roving form, followed by a comparative study with conventionally industrially produced yarn, using open-end industrial spinning.. Physical parameters such as twist, count, elongation, tensile strength, and tenacity were analyzed using USTER AUTOSORTER 5, USTER EVENNESS TESTER 6, and AUTODYN II MESDAN instruments. We have obtained the following results for the designed equipments: twist 424 tr/min, count 15.24 tex, elongation 7.81%, tensile strength 3.77 N, and tenacity 25.92 cN/tex, compared to 437 tr/min, 14.33 tex, 8.38%, 3.13 N, and 22.02 cN/tex for artisanal equipment. Morphological analysis revealed irregularity rate, size, fineness, imperfection count, and hairiness of 15.95%, 36.66, 19.33, 23, and 1262%, respectively, for the designed equipment, as opposed to 17.13%, 81.33, 29.4, 54.2, and 1919% for artisanal equipment. Based on these results compared to yarn produced industrially, we can conclude that this equipment allows for the production of industrially acceptable quality yarn, with a daily production capacity 13 times higher than that of traditional equipment.
