Productivity improvement in a dyehouse in the textiles industry

This dissertation describes the application of productivity improvement techniques in a dyehouse in order to reduce costs and to improve quality and delivery performance. It consists mainly of investigations into the high reject rate in the dyehouse and into the dyeing process itself. In these, the technique of Pareto analysis and the application of the principle that all processes contributing to product quality should be controlled, were applied. In addition, work study techniques were used to improve process flow, planning and batch sizes. A number of conclusions and recommendations were made: there are no major obstacles to successful first-time dyeing; the proportion of rejects produced tends to increase with increasing workload; the overall ability of the dyehouse operators and supervisors needs to be improved; the dyeing process is very vulnerable to human error, and increased automation, such as the purchase of a more sophisticated machine control system, is recommended; investigation into the purchase of a colour matching computer is also recommended.
