【正文】 C)applications, such as rubber pretreatment and vulcanization, food processing, wood curing, textiles, polymers and biochemistry. In most of these areas the technology has been successfully mercialized, and lowtemperature industrial microwave furnaces are now available worldwide [3].In this study microwave energy and its properties are discussed for increased applications of MW in textile sector. The information relative too textile finishing applications, advantages, processing efficiency and contribution to energy gain are given.2. General Structure of Textile SectorTextile is covering the processes which start from fibers such as spinning, weaving, knitting and dyeing. And apparel industry covers transformation of this process to the user stuffs. From fiber to finished fabric all processes are assessed as textiles and the process from finished fabric to garment is assessed as confection sector.Textile and apparel are important building blocks for industrialization period and this is the leading labor intensive sector which makes major contributions to recovery of developing countries.Turkish textile and apparel sector is a strong position of Turkey’s economy as both provided employment and in excess of one billion dollar export revenue. According to January 2010 data of Social Security Institution, while 687 441 insured people are determined as working in textile and apparel sector, in general 2,5 million people is estimated to be employed. Additionally 40320 offices have been registered in textile and apparel sector according to social security institution. On the other hand, there are approximately 11 000 manufacturing and exporting panies within and around the city of Istanbul.According to the published statistical study of International Textile Manufacturers Federation (ITMF)about the sales of textile machinery in the world, as of 2008 in terms of machinery park, 3% of the short fiber spindle capacity, 5% of the long fiber spindle capacity, % of open end (OE) rotor capacity, % of cotton system shuttleless loom, % of cotton system gripper shuttle loom, % of silk/filament weaving loom and % of wool woven fabrics are located in Turkey. According to the same study, for the European part of the study, % of the short fiber spindle capacity, 12% of the long fiber spindle capacity, 19% of the OE rotor capacity, % cotton system shuttleless loom, % of the cotton system gripper shuttle loom, % of the silk/filament weaving loom and % of the wool woven fabrics are located in Turkey.3. Energy Usage in Textile Sector Textile industry is one of the industries which use intensively water and energy. Very high amount of energy and water is being consumed and long lasting process is required during wet processing, especially washing off, dyeing, rinsing, desizing, being hydrophilic and bleaching [4]. In addition, technological improvements in textile industry increase energy consumption ratios. According the results of a survey made by Turkish Textile Finishing Industry Association, energy costs (16%) have the biggest share after human resources (26%) in expenditure [5]. In reference to 2010 general energy balance, approximately 40% of energy and 47% of electricity consumption originates from the textile industry in Turkey [6]. Power usage values in Textile industry are shown in Table 1. Electricity consumption (in terms of tone equivalent to petroleum TOE) indicates the maximum value for all textile industry as shown in Table 1. Similar results are also seen in textile finishing sector that uses the most energy (Table 2).Table 1.

For this reason the use of MW radiation in especially textile finishing processes, is expected to decrease electricity consumption and make a favorable contribution to the Turkish economy in a very short period of time.Table 2.
