The Textile Industry is one of the largest industrial sectors and the fifth largest exporter of the textiles employing 45 million workers in India. The Indian textile industry has changed its ways in the production of finished textiles, Energy is involved in each of stage processing. Thus, this study aims to evaluate the energy efficiency of the processes in the textile industry and identify opportunities for improvement in the process involving raw fabric to the finished textile product. The energy efficiency determination in an industry can be evaluated by the energy consumption of the respective process equipment in an industry which includes the performance evaluation of the textile manufacturing processes. This paper describes the operations in textile manufacturing such as weaving, yarn production, spinning, drying, and also the significance of PAT schemes in energy improvement opportunities for various industries, including the technical improvement studies and also provides the brief description on validating various unit operations and respective parameters that affect the performance of various process equipment such as stenter, heaters, compressors, motors, and other non-production equipment. This review paper also described the impact of PAT cycle 1 in validating the energy intensity of technologies used in textile industries and some important measures required to improve the energy efficiency of a process as this could improve the functioning of the system. The best available techniques in the process has also been discussed in the sections which can be implemented in practice for improving the energy efficiency of the processes.
