Abstract

This project was executed in Crescent Bahuman Limited which is a vertically integrated denim unit in district Hafizabad, Punjab. Crescent Bahuman Limited is pioneer in denim manufacturing in Pakistan. The Heart of manufacturing denim is rope dying process where yarn is dyed in indigo shades to get desired color of final denim product. CBL was facing limitation in its research and development as it was lagging in technology in what is regarded as core process in producing denim. A classic 1994 GMC rope dying machine was used for this purpose which surely had its limitations keeping in view the market has moved on to more sophisticated processes and it was about time CBL moved to a newer version or modify the existing machine after analyzing its mechanical structure. It was decided that machine would be modified to new control system, for this purpose meetings were held with Smartec, a leading name in rope dying machine manufacturing. A proposal was approved and project was approved after formal sign off. This modification work of a rope dying machine included replacement of all electrical control system, instrumentation.
