“…Rest of the energy that is used in the textile processing plants is supplied by other energy sources of fuel, natural gas, and coal. 8,9 Sizing process is an important process between spinning and weaving processes. Sizing of yarns before warping mostly requires indirect steam that is heated using electricity, gas or oil.…”

A cost minimization concept of heat and energy consumption for direct dyeing process of cotton fabric coloration was experimented with triethanolamine instead of sodium carbonate in the dyebath of direct dyeing with low temperature at 30˚C, medium temperature at 60˚C and high temperature at 90˚C and compared with the conventional method of direct dyeing with high temperature at 90˚C where an acceptable range of increasing color strength (K/S) and color difference were observed for low temperature dyeing with triethanolamine (TEA method) comparing to the conventional dyeing process of high temperature with sodium carbonate (SC method). Considering heat and energy consumption in direct dyeing of cotton fabric coloration with triethanolamine method, the low temperature dyeing cost was minimized Rs. 2.24 comparing to high temperature sodium carbonate method dyeing cost.Citation: Hossain A, Samanta AK.

“…In India, the Textile industry contributes 14% to the total industrial production, 4% to the GDP and 11% to the country's export earnings. This is also an energy-intensive industry and is the second largest industry in the world in terms of fiber production and employment generation (IBEF, 2014;Palanichamy and Sundar, 2005). This sector has large process variants in terms of products, namely, man-made fiber, cotton, handloom, woolen, jute, and sericulture and silk.…”

The annual consumption of petroleum products in India was about 221 million metric tons in 2015. Of this, 84% was imported. The Indian industrial sector accounts for about 16%-20% of the total fuel consumption for thermal energy for different heating applications in the temperature range of 50°C-250°C. Solar collectors can meet these temperature requirements and offer the possibility to mitigate the consumption of oil. This study highlights the fact that conversion efficiency from solar energy is much higher for process heating than for electricity generation and that process heating applications constitute a significant share of industrial energy consumption. In this paper, a methodology has been developed to estimate the potential for integration of solar collectors for process heating. The methodology employs process operating temperatures to select the type of solar collectors. The size of the solar field is estimated taking into account the thermal heat loads, working fluid and temperatures of these processes, the efficiency of the chosen solar collectors, location-based solar irradiance and capacity utilization of the solar collectors. The proposed methodology has been validated with a software tool called System Advisor Model (SAM). The techno-economic analysis will indicate the viability of solar systems for integration in industries. Therefore, the consociated parameters on economic (capital cost, fuel oil savings, monetary benefits), financial (Payback periods, Rates of Returns) and environmental (Carbon savings) are estimated. Further, the methodology has been applied to select Indian industries to verify its potential quantitatively. The industries selected include Textile, Pulp & Paper, Dairy, Leather and Automobile. Processwise energy demands are considered while estimating the potential as the fuel requirement offset by solar energy in terms of absolute fuel oil savings, monetary benefits and carbon savings. The other economic and financial parameters mentioned above were estimated to verify the capability and present the market position of solar systems. Further, sensitivity analyses have been performed with respect to solar energy penetration and fuel oil prices to address the viability of integration of solar energy for process heating.

“…Although OTI is a vital industry sector with significant energy consumption, few scientific papers have addressed energy efficiency issues in this industry. Palanichamy and Babu (2005) acknowledged the fruitful energy conservation experiences of the Indian TI and proposed the potential of increased energy efficiency. Ozturk (2005) estimated the energy consumption per production for the textile sector and surveyed the relationship among energy usage, energy cost, and textile production.…”

This study analyzes the overall textile industry (OTI) energy efficiency gap between China and the US and measures the longitudinal changes in OTI energy efficiency over time. A breadthwise comparison of the energy efficiency among OTI subsectors indicates that the chemical fiber industry (CFI) is the key subsector for improving energy efficiency. This study conducts a quantitative analysis of the influencing factors of energy efficiency of the CFI in China. The energy efficiency of the CFI in Fujian and its influencing factors are compared with that of the national level. Results indicate that the main factors influencing the energy efficiency of CFI in China include economic structure, energy structure, industry scale, and technology, whereas industry concentration has no significant effect. Economic indicators show that the energy efficiency of
