| Abstract | ||||
| In the present work, the rate of end-breakages during the spinning of carded yarns 20 Nm up to 50 Nm from Egyptian (Giza 75) cotton fiber have been observed. The phenomenon has been investigated considring the effect of twist, draft, spindle speed, traveller weight and doffing position. The experiments were carried out by varying two-variables at different levels and three-variables using 33 factorial design technique. The results declared that the end-breakage rate was found to be influenced significantly by: twist, draft, spindle speed and doffing position. In addition to the above parameters, the two-factor interaction such as spindle speed with doffing position and spindle speed with traveller weight affect significantly on the rate of ends down. | ||||
