Zusammenfassung:	Using a burn-out processing agent which is safe or of little pressure on environment to provide a fabric and a burn-out processing method thereof featuring sufficient burn-out effect free of strength reduction after treatment. Being a weight reduced fiber, a modified polyester fiber is copolymerized from: ethylene terephthalate as the main unit of structure; aliphatic dicarboxylic acid in mole fraction above 12 mol% and below 25 mol%, with carbon number above 4 and below 8; and metal sulfonate-based aromatic dicarboxylic acid in mole fraction above 2 mol% and below 5 mol%. The fiber number per filament of the modified polyester fiber is above 0.6 dtex and below 3.5 dtex. A mixed fabric containing at least two fibers of modified polyester fiber and a common polyester fiber optionally further comprising polyurethane fiber can, by comprising as the burn-out promoter, such as Meiprinter OP-2 produced by Meisei Chemical Co., Ltd. and sodium carbonate burn-out processing agent, obtain excellent burn-out and have le
