Color hazing or decoloring agent and method of producing fabric

A method of producing a fabric, the method comprising carrying out color hazing or decoloring of a fabric printed or dyed with a disperse dye, by heating the fabric while contacting with a color hazing or decoloring, wherein

• the color hazing or decoloring comprises at least one compound selected from the group consisting of compounds represented by general formula (1) and compounds represented by general formula (2):
• R1OOC—X—COOR2 (1)
• Y1O-(AO)n—Y2 (2)
• wherein,
• in general formula (1), X is an alkylene or alkenylene group of 2 to 4 carbon atoms, R1 is an alkyl group of 1 to 4 carbon atoms and R2 is an alkyl group of 1 to 4 carbon atoms, and
• in general formula (2), AO is an alkyleneoxy group of 2 to 3 carbon atoms, n is an integer of 1 to 3, Y1 is a hydrogen atom or an R3CO group, R3 is an alkyl group of 1 to 4 carbon atoms, Y2 is a hydrogen atom or an R4CO group, and R4 is an alkyl group of 1 to 4 carbon atoms.
