description The invention discloses a preparation method of a macamide finishing agent for fabric finishing. The method includes the steps of dissolving PEG in acetone, adding TDI under the condition of water bath cooling after complete dissolution, adding a proper amount of initiator, and stopping reaction after a certain period of time; uniformly mixing macamide and a prepolymer obtained in the step A according to a certain proportion, adding the mixture into aqueous solution containing an emulsifier and a dispersion stabilizer under the conditions of heating and rapid stirring to form an oil-in-water emulsion system, adding a chain extender after emulsifying until the particle size of the microcapsule meets the requirement, and continuing for a certain time under the condition of constant-temperature stirring; and obtaining the macamide finishing agent. According to the preparation method of the macamide finishing agent for fabric finishing, maca microcapsules coated in the form of polyurethaneare used for finishing,
