Abstract
An investigation of the factors which affect lead time in spinning mills producing carded and combed counts is reported. Data were collected from 27 mills producing 40 Ne Carded Yarn and 9 mills producing 40 Ne Combed Yarn. A number of 13 parameters which affect lead time were identified and they are FQI (Fibre Quality Index), Roving Production, CSP (Count Strength Product), Yarn Realisation, Spindle Production, Top Arm Roller Pressure (Front), Top Arm Roller Pressure (Middle), Top Arm Roller Pressure (Back), End Breaks, UKG, HOK (the number of Operative Hours required to produce 100 kg of yarn), YQI (Yarn Quality Index), Machine Utilisation. Multiple linear regression analysis have been carried out to find out the dominant parameters which affect lead time. While 71.4% of the variables account for lead time in respect of carded counts, about 78.4% of the variables have dominating influence in combed yarns.
